Orbital Cutting Machines by PROTEM

Orbital Cutting on Tubes

Tube cutting is a necessary machining operation for the prefabrication, construction, maintenance, repair or removal of damaged parts, caused by corrosion, for example.

2017-03-03 065504

Tubular components are affected by channeled substances that affect the original condition of the tube. Oil, gas or water at high-pressures are abrasive and can alter the corrosion of the tube either chemically and/or mechanically.

When the replacement of the tube is absolutely necessary, the cut is made in upstream and downstream sections of the damaged tube. This maintenance operation can be done on-site and requires the best equipment for a perfect surface quality before performing welding operations.

Orbital Cutting Machines by PROTEM

PROTEM tube cutting and beveling machines are portable machines.
They are light weight, reliable, easy to use and they ensure a perfect weld preparation with no heat affected zones on all types of materials, such as, steel or inox tubes.

2017-03-03 065443

The PROTEM product range includes several types of cutting and beveling machines:

  • TT-NG Orbital Cutting Machines cut and bevel tubes with large wall thicknesses.
  • The TT-LW Series Machines, with a simpler design, cut and bevel tubes up to 25.4 mm (1″)
  • The TTS-NG Machines allow accurate cutting and/or beveling of tubes and pipes, of all schedules, from 10.3 mm (.406’’) up to 273 mm (10.7’’) OD in one simultaneous operation.
  • The TTS-RD machines have been specially developed to cut thin-walledl tubes from steel and titanium in restrictive space conditions.

They are composed of two rings; one fixed and one rotating. The tool holders are mounted onto the rings. They can be opened into two “half-shells” which allows them to be mounted on any type of pipe at the required place for machining.

CASE STUDY:
Machining a by-pass connection welded on a valve located in a nuclear facility.
The angle and the root face of the connection failed to meet the specifications for the welding operation.
The installation of the valve on a lathe is very complicated.
SERCO has, therefore, been requested to machine this connection directly on-site while respecting the dimensions and the tolerances of the drawing (0.1 mm (.004”).
• ID of the connection: 25 mm (1”).
• OD of the connection: 34 mm (1.339”).
• Tolerance of the root face dimension: 0.1 mm (.004”).

EQUIPMENT USED:
PROTEM US25 pipe beveling machine with pneumatic drive.
• Mandrel - Ø 18 mm (.709”).
• Specific tool bits.
• Protective collet for the ID of the connection.

2017-01-30 091717

MACHINING TIME:
Assembly of the machine.
+ adjustment of the machine in the connection.
+ machining of the connection.
+ disassembly of the machine.
TOTAL : 20 minutes

2017-01-30 091732

RESULTS:
The customer performed a control with the use of a wax molding.
The result was verified to the tolerances requested.
The use of a portable machine avoided the need to install the valve on a conventional lathe.
The adjustment on a lathe would have required a great deal of time.
In addition, the accuracy would not have been guaranteed.
Only the PROTEM machine was rigid and accurate enough to perform such a machining.

In an industrial setting, a material is never selected by chance. During the design phase, the characteristics of the materials must be carefully studied and determined in order to avoid subsequent complications when in use, and to avoiding incurring unnecessary costs.

This is especially the case when choosing a material to be used in a pipe. This is because some pipes are subjected to considerable mechanical, thermal or chemical stresses, depending on the type of fluid they convey, with pressure and temperature playing a determining role.

The material used to manufacture the pipe has an influence on all the manufacturing operations, including machining. The machinability of the pipe depends directly on the material used to manufacture the pipe, and for each given material, specific precautions must be taken in order to ensure high quality machining.

Machining is a common operation when preparing a piece for welding. The pipe end has to be machined at specific angles so that the weld can penetrate the entire thickness of the pipe material.

Standard steel

Standard steel pipes are the most commonly used types of pipes owing to their low cost and mechanical properties which make them suitable for a wide range of applications. Steel pipes are resistant to mechanical stresses, durable and formable. This means that they can be used for applications with significant temperature or pressure variations. Standard steel pipes are also very commonly used in situations where impacts or vibrations can affect the pipeline (underneath roads, for example). In addition, steel pipes are fairly easy to manufacture, bend and cut.

Steel pipes are, however, very prone to corrosion if no preventive treatment is applied. Galvanization is a common corrosion-control treatment; this consists of applying a zinc coat to the steel pipe. This coating then oxidizes in the place of the steel which it protects, with the all-important difference, however, being that the zinc oxidizes very slowly.

Low-alloy steel (i.e., with a low carbon level between 0.008% and 2.14%) can be easily machined. When the carbon rate increases, the material properties (such as hardness or mechanical resistance) tend to improve significantly. However, machining steels with a high carbon level is more difficult.

2016-10-28 093208

P91 Steel

P91 steel is an alloy steel with a high chromium (9%) and molybdenum (1%) content. Adding chromium increases the mechanical resistance at high temperatures as well as corrosion resistance, and adding molybdenum improves creep resistance. Small amounts of nickel and manganese are added to enhance the overall hardness of the material. P91 steel is very sensitive to changes in its microstructure that can occur during excessive heating. These microstructure variations tend to weaken the material. This is why cold machining is often preferred for cutting this material.

P91 was initially developed for the manufacturing of pipelines in conventional or nuclear thermal power plants, where the steam leaves the superheater of a boiler in a modern conventional/thermal plant at a temperature of between 570°C to 600°C and a pressure of 170 bars to 230 bars. This means that the final stages of the superheater and the pipelines delivering the turbine steam must be able to withstand these extreme conditions. In such a case, the high mechanical resistance of P91 and its fatigue strength makes it the right choice.

By using P91 in such circumstances, the engineers were able to reduce the thickness of the pipelines while simultaneously increasing the operating temperature, all of which enhances the overall thermodynamic efficiency of a power plant.

The high mechanical resistance of P91 steel means, however, that machining is difficult. Thus, the tool bits should be changed regularly to ensure their sharpness, and the cutting speeds should be kept slow. The feed rate can also be adjusted to increase the machining speed.

2016-10-28 093300

Duplex steel

A Duplex stainless steel consists of stainless chromium steel with nickel added. The matrix contains both ferrite and austenite, hence the name Duplex. This alloy was designed to provide corrosion resistance and tensile strength. Duplex steel pipes are very commonly used in gas and petroleum offshore platforms where the pipelines are subjected to intense pressures and corrosive elements (salt water). Duplex steel tubes can also be found in industries with chlorinated products and acids, such as in the chemical or pharmaceutical industries. In recent years, more strongly alloyed Duplex steels have emerged under the name of Super-Duplex or Hyper-Duplex.

Duplex steel pipes are relatively difficult to machine due to their tensile strength and high yield strength. This can lead to very high cutting temperatures and to plastic deformation of the pipe. In any case, the tooling and clamping must be sufficiently rigid and stable in order to machine a Duplex steel pipe.

2016-10-28 093412

 

Stainless steels

Just like standard steels, stainless steels are comprised of iron and carbon, to which chromium has been added. Upon exceeding a certain proportion of chromium (10.5%), a chromium oxide layer is formed on the steel surface. This so-called “passive layer” is chemically inert, corrosion resistant and stable.

Other elements can be added to improve the mechanical strength (nickel) or high-temperature performance (molybdenum, titanium, vanadium, tungsten).

Although more expensive than standard steel pipes, stainless steel pipes are widely used in many industries (chemical, petroleum, pharmaceutical, food, aerospace, shipbuilding, etc.).

Their popularity stems from their corrosion resistance and chemical stability which make stainless steel piping suitable for fluids that must not be contaminated (pharmaceutical industry, food industry, etc.) and for corrosive fluids (the chemical industry, in particular).

The machinability of stainless steel is highly dependent on the proportion of alloying elements. Specifically, a high proportion of chromium, nickel or titanium makes machining more difficult, whereas adding carbon or sulfur facilitates machining.

The cutting edge must be sharp to facilitate chip detachment from the material and reduce the cutting forces.

The cutting tool must be sufficiently well assembled and the machine itself must be sufficiently rigid to support the forces caused by machining; as a rule of thumb, the forces deployed when cutting stainless steel can be more than 50% higher than with standard carbon steel.

2016-10-28 093601

Superalloys

Most of the superalloys used to manufacture pipes belong to the range of nickel-based superalloys. This range includes Inconel and Austenite, named after the alloy manufacturer.

Therefore, the alloy base is nickel which can be alloyed with chromium, iron, titanium or aluminum. These alloys have the same advantages as stainless steels, but to a greater extent. Specifically, their heat resistance is higher (about 900°C) as is their corrosion resistance (corrosion in chlorine ion solutions, ultrapure water and caustic mediums). They are also much more expensive than standard alloys, but this is justified for applications where operator safety is an essential criterion.

Pipes made from nickel-based superalloys are used in aerospace (in combustion chambers, for example), the chemical industry (due to their corrosion resistance), nuclear engineering, and, to a lesser extent, in the food industry.

Superalloys are considered very difficult to machine. This can be attributed to several factors. First, one must bear in mind that 70% of the heat is returned directly to the cutting tool (as opposed to 15% for standard steel, for example). Therefore, it is essential to keep the cutting-edge cooled during machining. The second complication is the hardness of the material; in fact, the lifetime of a cutting tool used to machine a superalloy can be reduced to just a few minutes if the tool does not have the necessary power, or if the cutting speeds and tools are not suitable.

2016-10-28 093648

Titanium

Titanium is an extremely interesting metal for the industry. Titanium can be used to manufacture pipes which are light and yet highly resistant to corrosion and able to withstand very high temperatures (600°C). Its mechanical properties (resistance, fatigue and ductility) are also appreciated. Titanium is, however, expensive and this limits its use to specific applications. In general, one finds titanium in the aerospace sector where its low density combined with its attractive mechanical properties make it an essential material.

Since the thermal conductivity of titanium is very low (about ten times lower than steel), the heat dissipation during machining is relatively poor. Therefore, the cutting edge needs to be properly cooled to avoid machining defects.

Sharp tools should be used to facilitate chip detachment from the material, and thus reduce the cutting force.

Machining is even more difficult in the case of treated titanium (e.g., treatment by precipitation hardening, presence of chromium coating or alloying).

2016-10-28 093733

Aluminum

Aluminum is very widely used in the industry. Aluminum pipes are inexpensive, easy to form and assemble. They are also light and corrosion-resistant, making them a natural choice in the aeronautics, transport and construction sectors. Aluminum pipes are also used to build compressed-air pipelines.

Aluminum pipes have a very low level of hardness, and are therefore relatively easy to machine. However, the malleability of aluminum can cause problems (shavings can lead to machine jamming, for example). In this case, the best response is to increase the cutting speed, the depth of the pass and the feeding speed. There is also a risk of aluminum pipes being deformed during machining if the machine tool, and in particular, the clamping jaws, are not correctly chosen.

The high thermal conductivity of aluminum allows for good heat dissipation. Thus, the cutting speed can be increased without reducing the lifetime of the tools.

TU TE series from Serco

2016-04-07 063844The TU TE series of machines is like a portable CNC machine with a numerical center. This machine allows standard operations such as facing, boring, beveling, and can also create landings and threads.

There is already opportunity for the standard operations, but these are improved with the new TU TE series. The machine can perform facing operations, but also, an improvement on this function, the cutting speed is not dependent on diameter. Boring is also improved because there is no minimum speed due to the brushless motor.

While serrated surfaces are possible on the standard machine, this machine has more possibilities. Because of the programming capabilities, the space between serrations can be variable and creating concentric circles is much faster. Beveling is a function of the standard machine, but also improved with the new series, with a longer stroke depth and unlimited possibilities of beveling angle.

At first, the goal of the machine was to create a way to thread with a single tool bit instead of a tap, but this machine has many more capabilities. A tap can be easily broken, which can cause huge problems, especially with large or expensive equipment. With single point machining, the tool can be easily changed if broken, with almost no lost time.

2016-04-07 063907Another advantage of the new series is the ease of switching from manual to programmed mode. The manual functions are still important, but when programming is needed, it just takes the push of a button. By writing a program for the machine, any shape can be created.

These machines have high rigidity and precision, both necessary for threading. There cannot be any play in the machine at all during the threading process because the tool must pass at the same precise location each time to create perfect threads.

2016-04-07 063919Another improvement is the ability to control the machine remotely – although the controls are attached by a cord, the control box can be moved away from the machine which is a huge advantage when radiation exposure is possible. Programming can also be done remotely as long as the machine is connected to the internet.

This machine has a similar application to a lathe or grinder, but is portable and lightweight and has a brushless motor, so it can go anywhere and the motor has no risk of spark.

Because of this new technology, we are learning more every day and stepping up in innovation.

The TTNG Series is the premier choice for perfect welding preparations.  Over decades our machines have undergone advanced development and have consistently delivered reliable technology.

Each TTNG meets the demand for high accuracy in today‘s welding applications.  They are designed to machine virtually any wall thickness, perform superbly on heavy wall tubes and pipes, and have been applied successfully on materials with high hardness. TTNG cutting and beveling machines are versatile, dependable, feature powerful drive motors, and a durable yet light weight design. Machines you can trust!

2015-07-22 094919

The machines are mounted to pipe by opening the two half-shells connected with a single hinge, greatly simplifying the mounting process.

Concentric alignment is achieved by independently adjustable clamping jaws; perpendicularity is adjusted simultaneously. Additional clamping screws are tightened to distribute and bear the axial forces. Tool carriages with covered bearings and gears protect against the ingress of chips and debris; this ensures long machine life.

Two tool carriages equipped with the tool bits can perform a simple cut or will cut and bevel in one operation. Two incremental feed speeds can be selected. The machines can be operated in all rotated positions.

A wide range of modular options extends the capabilities of the TTNG machines:
•    Carriages with double stroke length
•    OD-Tracking carriages to follow the ovality of the tubes
•    Counterboring carriages to perfectly round the inside diameter
•    Copying carriages to perform j-bevels or compound bevels on heavy wall pipes
•    Cutting wheels for chip free cutting operations
•    Enveloping jaws for thin wall thicknesses
•    Remote control for hazardous operations such as: radiation, deep waters, and others
•    Axial copying carriage to perform profile matching on the outside diameter
•    Flat gearbox and radial positioned drive with no exposed parts on the backside
•    Milling modules instead of the tool carriages for special applications

Bevel shapes & angles: I, V, U, X, Compound Bevels, Others upon on request
Feed: Automatic with clutch
Motorization: Pneumatic or hydraulic  Electric drives upon request

2014-08-14 103407 protemSome maintenance or repair works can suppose that some parts or components will have to be put on a workshop fixed machine which will be mobilized for those works. This will mean that in most cases, the following actions will have to be done:

- First, the part(s) will  have to be disassembled.
- They will have to be packed for the shipment.
- A specific shipment will have to be organized.
- If the case arises, the parts will be stored awaiting the availibity of a lathe, or of a milling machine or other appriopriate workshop fixed machine.
- Several persons, including material handlers, will also be mobilized.
- A return shipment will have to be organized.
- Strict and complicated handlings will have to be performed in order to avoid damaging the parts during their shipment and during their re-assembly on site.
- Any other actions which will be necessary (particularly, if the components that need a re-machining, a maintenance or a repair, have been subject to hazardous environment - ionizing radiation for example...).

An on site machining, performed by machining professionals, with portable machining equipment adapted to the need, represent then an undeniable better solution:
- the operator is travelling on site
- the operator performs the job directly on the part to machine.

PROTEM and SERCO machines are portable machines, designed to perform on site high quality machining operations.
PROTEM and SERCO operators are experienced technicians, able to operate on your sites, whatever they are, wherever they are.

- have machines known all over the world, for their quality, their sturdiness, their reliability and their capacities;
- are professionals who offer the industry their know-how and competences.
