A breakthrough in high integrity tube connection technology offering instrumentation system designers and installers major performance and time-saving advantages is now available from Parker Hannifin - the global leader in motion and control technologies.
- flared cone design prevents tube ejection and incorporates redundant second seal for enhanced reliability
- very short make-up time: up to 5 times faster than traditional cone and thread
Designed for working pressures as high as 22,500 PSI (1,550 bar), the new 'flared cone' technology advances the performance of compression style tube connections. It provides users with a simple and reliable means of speeding the assembly of instrument tubing systems for use in higher pressures applications in the oil and gas industries.
Developed by Parker Autoclave Engineers, the new flared cone connection (FCC) technology is a significant advance on the type of 'cone and thread' tube connections pioneered by the company.
The new flared cone connections are much simpler to make up. Installers can typically complete the task in less than four minutes, after only minimal training. This time-saving can result in significant cost reductions on installations with a large number of tube connections. Flared cone connections are also especially cost-effective in applications where leaks caused by vibration are an issue.
According to Michael O'Keane, Product Marketing Manager for Parker Autoclave Engineers, "Our new FCC technology offers the best of both worlds. It combines the make-up and installation simplicity of compression style connections with the strength of cone and thread, and has more features and higher pressure capabilities than similar technologies."
Parker Autoclave Engineers' patent-pending FCC technology is based on a single sleeve compression style system. However, unlike conventional designs, the tube end is flared to prevent any possibility of ejection - and also provides the connection's primary metal-to-metal seal. When the gland nut is tightened, the inside surface of the anti-ejection flare mates with a cone in the fitting or valve. The compression sleeve then mates with the body of the component to form a second, redundant, metal-to-metal seal. This dual seal approach has a major reliability benefit; in the unlikely event that the primary seal fails, the secondary seal preserves the integrity of the connection. Installing a flared cone connection is simply a matter of screwing the gland nut into the fitting or valve and tightening it to the prescribed torque.

A choice of three styles of modular fluid distribution manifold, backed by a factory configuration service, has been announced by the Instrumentation Products Division of Parker Hannifin – the global leader in motion and control technologies.
Parker's new manifold range supports a wide range of applications, from the distribution and control of low pressure instrument air or plant air, to high pressure instrument or hydraulic applications operating at up to 6000 PSI.
Two of the distribution manifold options are based on ball valves for quick on-off actuation and control. A further option offers a needle valve manifold, to suit applications that might require lower flow rates or more precise control, or compact construction.
The first of the ball valve options, the Hi-Pro Distribution Manifold, is based on a 10 mm orifice version of Parker's Hi-Pro ball valve - which is rated for pressures up to 6000 PSI. Up to 20 of these 316 stainless steel valves can be factory-assembled to order by Parker onto the distribution manifold base. Users can also specify other build options including fitting a purge valve.
A similar style of manifold is available for lower pressure air distribution applications. This version - the Hi-Pro Air Header Manifold - provides up to 20 Hi-Pro 10 mm ball valves mounted onto on a distribution manifold body made from a two-inch 316 stainless steel pipe with either a flanged or threaded inlet at one end. The manifold is rated for pressures up to 800 PSI depending on the options specified.
Parker's third option - H Series Distribution Manifold - provides a compact manifold body that accepts a user-defined choice of five or 10 metal-seated needle valves - rated for pressures up to 6000 PSI. Users can also specify numerous build options including the addition of a single isolate valve connected to the inlet.
An educational resource focused on raising the performance and reducing the risk of small-bore tubing systems will be on site at Offshore Europe 2013.
An educational resource focused on raising the performance and reducing the risk of small-bore tubing systems will be part of Parker Hannifin's exhibit at Offshore Europe.
The educational centre is part of one of the most recognisable booths at this regular exhibition: the mobile demonstration centre run by the instrumentation products division of Parker Hannifin - the global leader in motion and control technologies.
This year, Parker will be hosting mini training sessions, with experts providing no-cost tuition on the best practice installation of small bore tubing systems using industry-standard two-ferrule tube connections, and another version of the training for medium and high pressure connections up to 150,000 PSI. These valuable seminars will be complemented by many other useful educational presentations from Parker experts. Topical presentations throughout the show include materials selection for corrosion resistance, achieving close-coupling of instruments to piping connections, and improving integrity and reducing potential leak paths by eliminating threaded connections.
"Process instrumentation connections have evolved over a hundred years, and inevitably, connection and valve techniques are steeped in tradition," says Parker Hannifin's Charles Harris. "There's enormous scope for rethinking how things are done to provide more reliable systems and improve performance. Our mobile presentation centre gives us the means to give practical introductions on such innovations to instrumentation and piping engineers."
Parker's trailer will also feature the industry's most comprehensive selection of instrumentation valves, manifolds and tube fittings. Many of these are displayed in a real-world format using a long process pipeline equipped with the spectrum of common plant instrumentation, but interfaced using components based on next-generation principles.

The design of fluid instrumentation systems for use in harsh and corrosive environments has been boosted by an optimised new grade of 6Mo tubing.
The mechanical characteristics of the new ‘Parker Grade’ 6Mo tubing have been optimised to ensure integrity of connections made using instrumentation compression type fittings from the Instrumentation Products Division of Parker Hannifin – the global leader in motion and control technologies. Parker’s long history in specialpurpose alloy tube fittings has enabled it to build up a wealth of expertise and knowledge about corrosion resistant materials such as 6Mo. The company has played a formative role in the industry take-up of the alloy, which is now the material of choice for many instrumentation tubing systems on new and refurbished North Sea oil and gas production platforms. Containing at least 6 percent molybdenum, 6Mo alloy is a super-austenitic stainless steel. The material is more resistant to chloride-induced pitting, crevice attack and stress corrosion cracking than standard 300 series or duplex stainless steel, making it ideal for offshore applications demanding durability and reliability in a hostile environment. Parker produces 6Mo versions of various types of instrumentation tube fittings, together with a series of 6Mo tubing clamps, and can also machine instrument valves and manifolds in the material.
Many instrumentation system designers specify two ferrule compression fittings for the assembly of small-bore tubing, with the 6Mo version of Parker’s A-LOK design proving a popular choice for today’s offshore projects. As with all two ferrule fittings, the rear ferrule needs to be harder than the tube it is gripping so that it ‘bites’ into the tube material during assembly helping to create a reliable, pressure-tight seal. Parker hardens the rear ferrule of 6Mo A-LOK fittings using its unique Suparcase process, which provides marketleading corrosion resistance.
However, when ordering instrumentation tubing, customers often simply specify an ASTM standard to their supplier. These standards do not always guarantee an optimum material property for a high integrity tube and fitting combination. The result can be tubing that is harder than necessary, for example, and therefore less than ideal for use with twin ferrule compression fittings.
As part of its ongoing commitment to helping users improve the integrity and corrosion resistance of instrumentation systems, Parker ensures that all tubing stocked by the company and its distributors is fully compatible with its range of fittings. After exhaustive testing and analysis of 6Mo tubing, Parker has defined a stringent specification and tolerances for its manufacture that allows the material’s properties to be controlled very precisely.
By collaborating with its supplier and auditing the company to verify compliance, Parker is able to provide the new Parker Grade 6Mo tubing with mechanical characteristics that are optimally matched to the capability of its 6Mo instrumentation fittings. According to Paul Shaddick, Product Manager for Parker Hannifin’s Instrumentation Products Division, “Extending the reach of our quality control standards to encompass the manufacturing processes used by our supplier of 6Mo alloy tubing is a major step forward in our product development strategy. Our customers can now obtain all the 6Mo instrumentatio connection technology they need for an offshore project from a single source, secure in the knowledge that the components are compatible. This simplifies component procurement and distribution, helps speed installation, and eliminates potential leak paths in 6Mo compression fittings.”
Parker Grade 6Mo instrumentation tubing is available in a wide range of imperial and metric sizes up to 1 inch/25 mm OD, and its 6Mo A-LOK two ferrule compression fittings are suitable for the majority of topside applications involving pressures up to 413 bar/6,000 PSI.
