Description Our P-Seal is a static seal comprising a profiled elastomeric sealing element that is energised by the injection of plastic packing.
In operation, the inside diameter (primary sealing face) of P-Seal acts on the outside diameter of the casing/tubing running through it. The groove/recess in the opposite face of P-Seal accommodates the injected plastic packing to energise the system and create an effective seal.
Typical applications Used in casing and tubing heads to seal rough casing and production tubing. Specifications James Walker P-Seals have been tested in accordance with API 6A specification.
Construction Primary sealing element: either homogenous elastomer or rubberised fabric - a wide selection of top quality elastomers and fabric materials suitable for oilfield duties is available to meet customer specifications. Anti-extrusion elements: mesh of compressed stainless steel wire to BS EN 10088-3-1.4436 (formerly Grade 316 S33).
How supplied (P-Seal) Available to suit standard API casing/tubing sizes.
Plastic packing sticks
We manufacture two standard grades for duties with our P-Seal and other designs that are energised by the injection of plastic packing. Both grades are well proven for their thermally stable viscosity/flow characteristics, together with low friction and good surface adhesion.
Standard temperature packing sticks (LR5640/C2 grade) Hydrocarbon fluid-based, filled with PTFE and crystalline silicate, and reinforced with aramid fibres.
Higher temperature packing sticks (LRCM100/B grade) Silicone fluid-based, filled with PTFE, graphite and crystalline silicate, and reinforced with aramid fibres.
How supplied (Plastic packing sticks) Extruded in standard diameters of 19mm to 38mm (0.75-inch to 1.5-inch) and cut to lengths of 100mm to 300mm (approx 4-inch to 12-inch) as required. Other diameters and lengths supplied on request.
