fs casing & tubing seal

description
our fs casing & tubing seal has been specially developed to undertake arduous fluid sealing duties where there are large clearances between mating parts of wellhead and associated assemblies.
it has been tested in accordance with api re for use on surface wellhead-to-casing systems, where the seal can readily replace metal end cap and plastic pack sealing arrangements. 
special features
the combination of design, materials and construction ensures that high-performance fs casing & tubing seals retain their sealing integrity under adverse operating conditions, including:

• stab-in operations.
• wide ranges of temperature and pressure.
• chemically aggressive and highly asbrasive oilfield media.

operating conditions to api re
the fs casing & tubing seal has undergone dnv witnessed tests on rough casings in accordance with api 6a, appendix f, pr2 procedures. it is suitable for:

• maximum operating pressure: 69mpa (10,000psi).
• operating temperature range: -29°c to +177°c (-20°f to +350°f).

construction
the seal is precision moulded in rapid gas decompression (rgd) resistant hydrogenated nitrile hnbr elastomers. anti-extrusion capability is provided by two toroidal springs mould-bonded into the outer edges of the primary sealing face.

materials selection
hnbr elastomers:elast-o-lion® 101 or elast-o-lion® 985. both these grades are well proven for their toughness, wear resistance, rapid gas decompression (rgd) resistance, and broad temperature capability.

elast-o-lion® 101 is our premier rgd resistant hydrogenated nitrile grade. elast-o-lion® 985 is proven for use in very low temperature applications whilst exhibiting good rgd resistance.

toroidal springs (anti-extrusion): standard material is stainless steel to bs en 10270-3-1.4401 (formerly grade 316 s42). nickel-based alloy 600 - uns n06600, is also available.

installation
fs casing & tubing seals are system pressure energised, and designed to accommodate the od tolerances and surface finish of api 5ct casing and tubing. the stab-in end of the casing needs needs just simple hand-ground chamfer preparation before insertion.

the flexibility of the seal, combined with the benefits of securely mould-bonded springs, helps to simplify the fitting operation and ensure correct location in housings.

fs casing & tubing seals can be retrofitted to many conventional p-seal housings with minor modifications to the ports. the seals offer reductions in installation time without the need for separate pack-off operations.
