OD ORBITAL CUTTING & BEVELING MACHINES

50 years of experience and technical expertise worldwide

TT series machines ensure perfect cuts and bevels for maximum efficiency. Wherever the priority is to minimize installation downtime and maximize equipment runtime, you will find PROTEM TT machines.

TT series machines are a perfect example of PROTEM’s 50 years of knowledge and expertise in providing job oriented machining solutions.

2019 09 26 092118

TTNG

The tube cutting machines of the TTNG series are built to cut and bevel tubes up to 3.937” (100mm) thick (larger upon request) in the field. Their low clearance design of rotating parts is highly appreciated by customers in all industries such as Nuclear, Oil and Gas and Chemical.

Options for counterboring jobs, cam-copying operations and wheel cutting are possible within the wide range of diameters covered by each model in the TTNG series. The splitframe configuration opens in two half-shells joined together with a hinge. Clamping is ensured by independent adjustable jaws for easy in place set-up. The completely enclosed drive gears and tool holders provide an increased operator safety.

2019 09 26 092144

TTLW

If the TTNG’s low clearance is not enough for you, TTLW machines are the ones you need! These machines are the light weight version of the rugged TTNG. Because of their narrow and lightweight body design, they are the ideal solution for use in confined areas.

TTSNG

The TTSNG version are designed for machining small diameter tubes and pipes. They are built in the same manner as the TTNG machines which allow accurate cutting and/or beveling of tubes and pipes from 0.406” (10.3mm) up to 10.751” (273.1mm) OD.

TTSRD

The collet clamping system of the TTSRD series allows for quick set-up and an easy concentricity adjustment. This clamping method is particularly suited for small wall thicknesses in order to avoid tube distortion in case of poor machine set-up. These machines have the lowest clearance of the range.

2019 09 26 092209

Main advantages:

  • V track and rollers: The V shape design compensates for axial and radial forces to ensure maximum precision and less wear.
  • Aluminium body: Lightweight and durable for limitless machining jobs!
  • Splitframe design with hinge: Easier to set up on continuous or long length pipes.
  • Fully enclosed tool holder design: Protects the feed system from chips and prevents damage during machining.
  • Sliding tool holders: Easier and faster to set up.
  • Machine design permits cutting and beveling operation simultaneously, maximizes productivity!
  • Large diameter machines delivered with two standard configuration motors allowing more power for highly demanding jobs.

TT series machines are available in many configurations with standard or special accessories and options. All the devices provided with the TT series machines are built with the knowledge of PROTEM to provide enhanced performance and job specific solutions.

Axial and radial adjustable clamping jaws:

OD tracking tool holder

The OD tracker ensures consistent machining, regardless of the tube’s ovality. Its roller follows the tube’s OD profile and adjusts the position of the tool holder.

Radial Copying carriage

Copying carriage allows the user to machine any geometry of bevel thanks to a cam-following system. This technology of single point machining is particularly suited for heavy wall machining.

Axial copying carriage

It performs special shape machining on the inner or outer diameter.

Counterboring tool holder

Counterboring operations ensure consistent thickness all around the tube by machining the inside diameter. Operations of this type are essential when automatic welding machines are used.

Cutting wheel

The cutting wheel accessory allows the user to cut the tube without producing chips. The wheel is very useful when cleanliness standards require that no chips can be introduced inside the tube during machining.

Enveloping jaws

Enveloping jaws are designed to clamp the machine onto even the thinnest tubes without any distortion.

Remotely operated machine

TT series machines can be remotely controlled for operations in areas under ionizing radiation or in underwater/subsea environments.

Flat gearbox

Combined with radial positioned drives, this gearbox allows the user to fit the machine in extra low profile spaces.

Milling modules

The tool carriage is replaced by a milling head.

Special configurations and options on request.

In the field of welding, irrespective of the process used, when we examine what is needed for making a top-quality welded joint, preparation is an operation that is often neglected. Normally investments are made on what concerns the welding operation itself, unfortunately without taking account of any prior operations. But, this is a field where judicious investment can be a source of substantial savings.

Even now, certain preparatory operations for welding are done with a grinding wheel or other equally unsuitable tools. Poor preparation will affect the end quality of the weld and lead to rejects, breakage or even leaks in use if defects are not detected in time.

Good preparation for welding is even more important when mechanically welded structures are subject to heavy loads when in use (pressure, heat, mechanical stress, etc.). For example, this is the case in nuclear power or oil and gas industries, two domains where welding needs to be perfect.

Welding preparation equipment that is available on the market can meet practically all users’ requirements, in terms of speed, quality or even size. It also gives companies the possibility of making both rapid and substantial savings.

Splitframe Protem TTNG900Splitframe Protem TTNG900

What economic gains can be identified by setting up a suitable welding preparation system?

Productivity

Gains in time observed when using a suitable welding preparation tool rapidly prove to be considerable.

Preparing for welding on a 10” pipe with 1” thick walls only takes the operator a few minutes (5 at the most) with a PROTEM US80 inside clamping beveller for example, irrespective of the material to be welded (Austenite, Duplex, Inconel, stainless steel, etc.). By using a grinding wheel or other unsuitable tooling, the time taken for preparing for welding will easily be multiplied by 2 or 3 (between 10 and 15 minutes for a far-from-perfect result, which will necessarily be non-repetitive. An operator doing just five welds per day on this type of pipe will need to bevel 10 pipe-ends. If we count a gain in time of 10 minutes per bevelling operation, we will obtain a total saving of 100 minutes per day or 1 hour and 40 minutes. As the average hourly cost of industrial labour is 36.8 Euros, according to Eurostat data, the financial gain is at least 63 Euros per day, which makes a total of 14,238 Euros per year (considering that there were 226 working days in 2018). In this way, gains will rapidly cover initial investments made by the company.

Perhaps, this case study may not be representative of what can be found in all companies, but, even so, by making the calculation, keeping suitable equipment in mind and making a comparison with the savings made over a year, it can be seen very clearly that gains are by no means negligible.

Quality and repeatability

The cost of quality is a sensitive element when looking at welding in detail. Tolerances are increasingly difficult to attain, tests are increasingly precise and specification requirements are increasingly restrictive.  Suitable equipment for preparing welding operations is most certainly a real asset in the search for excellence, expected by contractors. But what financial gain can be found by using this type of machine when it is a matter of quality?

In fact, savings are visible on two levels. Firstly, the number of reject parts will drop naturally by mechanising the task. Tolerances will be maintained more easily and welds will be of higher quality. As a result, the time spent on re-machining reject parts could be devoted to production and make the company’s general productivity increase. A second form of saving can also be made by using this type of equipment. As the process is more reliable and more especially because it provides repetitive good-quality results, the need to check each preparation operation individually is no longer necessary. Statistical checks can be made (1 check every 10 preparation operations, for example, depending on the machine’s reliability) and, as a result, the company’s inspection costs can be drastically reduced (in this case, reduction is close to a factor of 10.

Protem Pipe Beveling MachineProtem Pipe Beveling Machine

Industrial catastrophe

This paragraph is the direct follow-on to the paragraph on quality. Whenever a poor quality weld succeeds in getting through all its inspections, costs can be calculated in millions or even billions of euros if ever a catastrophe occurs. This is the case in sensitive domains such as nuclear power, refineries or pipelines where the slightest defect is synonymous with catastrophe.

A number of accidents due to poor welding have marked history, such as what occurred at Romeoville, Illinois in the United States in 1984, where the explosion of a poorly welded tank killed 17 people and caused a loss of 200 million Dollars for the company. More recently, in 2004, a gas leak from a pipeline at Ghislenghien in Belgium caused an explosion killing 24 people.

Unfortunately, this type of incident is not all that rare in refineries and on pipelines and the only way of avoiding them is to implement clear welding procedures, based on the use of reliable equipment, irrespective of the level of welding, of preparation and of inspection.

OilGas industry

Safety and user-friendliness

Using a welding preparation machine is also consistent with safety improvement plans. An incorrectly selected machine may prove to be non-ergonomic for the operator, both noisy and dust-producing, both of which are dangers to health. Vibrations are also responsible for a large number of long-term disabilities.  

Choosing a light-weight, easy-to-use machine with practical functions such as torque control will undoubtedly cost money when it is acquired, but the acquisition will immediately reduce risks of injury and time off work, be this at short or at long term. At short term, fatigue will be felt less during the day, which will enable operators to be more efficient. At long term, muscular or bone affections will be less important if suitable equipment is used.

Therefore, safety and user-friendliness can be considered as being an economic benefit for a company that has a global view integrating purchase costs for equipment that contributes very considerably to optimizing its operators’ work conditions.

Splitframe Protem TTNG1200Splitframe Protem TTNG1200

The case of automatic welding

Certain companies would like to invest in orbital welding equipment for gaining time and improving quality when welding pipes and tubes. One of the most frequent mistakes is to neglect preparations for welding.  For automatic orbital welding to work correctly, it must be remembered that there must be no gap whatsoever between the pipes to be welded. Furthermore, ‘J’ shaped bevels are recommended for minimising the need for filling. As a result, geometric tolerances are very complicated to attain Accuracies required can only be attained by using a machine devoted to this type of preparation, a machine that possesses specific options such as a carriage capable of following the pipe’s profile or a counterboring system for maintaining a constant bevel over the pipe’s whole circumference.

Therefore, when investing in automatic welding, it is extremely important to plan for sufficient investments in welding preparation equipment or risk seeing the project fail completely by having automatic welding machines that cannot be used to their full capacity due to shoddily made welding preparation operations.

Conclusion

Therefore, choosing a suitable machine for preparing for welding is an economic asset no matter from what angle this type of investment is considered. It considerably improves productivity and quality. Operator safety is guaranteed and probabilities of a catastrophe resulting from a poor weld are reduced. Lastly, correct preparation for welding is an essential condition for carrying out welding operations, especially automatic welding, in total peace of mind.

Therefore, a company with a long-term view will not merely stop at the cost of the initial investment, but it will look in detail at all the potential savings that this type of machine can offer it.

Portable beveler saddle beveling machine

COMPETENCY, PROFESSIONALISM, QUALITY, SAFETY ARE OUR KEYWORDS

The saddle type tappings allow the perpendicular connection of lateral sections on main pipes. Saddle type tappings are located on collectors and boiler superheaters.

EQUIPMENT THAT POWER PERFORMANCE

2019 04 01 170444The saddle cut is created to produce a T-shaped joint to join the branch pipe to the main pipe. Once the saddle has been cut and properly fit, the field weld can be executed.

These T-shaped joints are mainly done with stationary machines or with Oxy-fuel cutting or grinding machines.

The process sounds simple, but because it’s cut by hand, it’s not always consistent, which requires a lot of grinding to make sure that the profile fits good enough to weld. Typically, though, one pass of grinding and fitting isn’t sufficient.

Using a tool designed for a specific purpose, in this case for beveling saddles, helps to ensure consistency in bevel angles and dimensions, which assists in making welds that are robust and durable.

2019 04 01 170510The portable US25GL Saddle Pipe Beveling machine is a portable, powerful, robust, reliable and versatile machining equipment.

The time to prepare (which can take up to one hour using conventional techniques), is now reduced to minutes thanks to the PROTEM US25GL Saddle Beveling Machine.

  • Medical/Pharmaceutical
  • Paper mills
  • Sugar refineries
  • Cement plants
  • Industrial Boilers
  • Cryogenics
  • Etc.

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.

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”).

2017-01-30 091700

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.
