Advances in metal-to-metal seal
technology
On-going development at James Walker Moorflex in manufacturing metal-to-metal seals and components for oilfield equipment has expanded the company's advanced capabilities
On-going development at James Walker Moorflex in manufacturing metal-to-metal seals and components for oilfield equipment has expanded the company's advanced capabilities in the CNC manufacture of annular products, typically incorporating complex sealing profiles and precise sections up to 2.3m diameter Precise annular rings incorporating radial and tangential drilling, slotting and threaded parts from 10mm to 2300mm diameter can also be supplied following the addition of CNC vertical machining and drilling facilities to the company's turning equipment

The company, in partnership with sister company James Walker and Co, has also developed a unique combined expertise in high performance elastomer technology and metal-to-metal sealing to produce advanced oilfield sealing products for equipment such as wellheads, chokes and valves.
Further products have also been developed to handle the most demanding surface and subsea environments.
Metal end cap seals.
James Walker Moorflex is also producing metal end caps which are used in fully bonded end cap seals.
These have complex profiles requiring specific surface finishes and close dimensional accuracy manufactured from difficult to machine materials.
With the seals radially compressed in operation, end caps make intimate metal-to-metal contact with housing surfaces, eliminating the potential for extrusion of the elastomeric sealing element in high-pressure service.
Solution-annealed and stress relieved in Stainless Steel 316 or Inconel 600, they are machined from special thin-walled billets.
Pairs of machined rings are fully mould-bonded to high performance elastomers at temperatures exceeding the maximum seal service level of +177deg C.
The one-piece moulded products are used as the primary seal in casing and tubing spools on wellhead equipment.
Suitable for service with hydrocarbons, sour gas, explosive decompression and injection fluids, the seals operate at down to -29C and at up to 1035 bar. Request a free brochure from James Walker Moorflex ...
