The next generation of materials for the oil and gas industry
As the oil and gas industry faces increasingly harsh and extreme operating conditions, the technology employed has to evolve in order to meet the new demands. Materials technology is no exception and for over 50 years James Walker has led the development of materials used in such harsh applications.
Manufacted in the UK by API-licensee James Walker Moorflex, these metal seals conform to both ASME and API standards.
Products include R, RX and BX ring joints, as well as lens, convex, wedge, double-cone and weld ring metal gaskets.
Tiflex® Acoustic Barriers effectively attenuate the transmission of noise and vibration between the floors of multi-occupancy buildings.
We have three grades that meet UK Building Regulations Document E, providing maximum performance at minimum thickness.
Our vast range of compression packings caters for all known operating conditions with valves, rotary and reciprocating pumps and similar plant. Exfoliated graphite packings, such as Supagraf® Control and Premier packings are proven for fugitive emission control in valves. In addition, many of our multi-service packings, such as Liongraf® are renown for long trouble-free operation in pumps and valves handling steam, fuel oils, process water and highly abrasive fluid media.
These products form the core of our oil and gas industry ranges.
Our high pressure sealing components range from O-Rings in a vast range of materials, to special ranges developed for dynamic or static duties on down-hole, wellhead, surface equipment, valves, pipelines and riser systems.
We have vast experience in the design and manufacture of customised and standard components in many high specification and exotic materials - as well as more general polymers such as nylon, polyurethane and PTFE. Our facilities enable us to produce parts in small batches up to millions, using techniques such as plastics moulding, casting, machining and bonding.
Comflex® expansion joints cover all duties and temperatures from -60°C to well over +500°C. Applications include gas turbine exhausts, hot air ducts, fans, boiler side walls and exhaust gas ducts. Our flexible bellows protect components from abrasive environments and retain lubricants on duties ranging from hydraulic rams to machine slides, and valve stems to screw threads on precision equipment.
James Walker companies supply industry worldwide with professional flange management and joint integrity programmes and services that go well beyond the accepted norms in terms of professional advice and planning, quality of on-site and off-site workmanship, standards of safety and care and customer satisfaction from initial survey to completion and beyond.
We have six 'flagship' grades of rapid gas decompression (RGD) resistant elastomer, each of which has been specifically developed for sealing duties in oil and gas production.
Three of these grades - Elast-O-Lion® 101, FR25/90 and FR58/90 - are qualified to Norsok M-710 for RGD-resistance and sour gas ageing.
Dedicated to the precision manufacturing of high-performance metallic components for use in industry’s most demanding applications.
Our machine shop specialises in the high-precision machining of geometrically complex components in exotic alloys.
RotaBolt® stud and bolt tension monitoring systems are accurate to ±5%. These are used across all industry sectors where the failure of a bolted system could have serious health and safety, environmental or financial consequences. RotaBolt tension control is recommended for structural, mechanical and flange tightening applications.
