Finite Element Analysis (FEA) is extremely important in critical seal design. JST conducted PR2 tests as per API6A, as well as FEA to its FS seal, S seal, valve stem packing seal, valve face seal. So why FEA is important and necessary? FEA capabilities make possible: 1. Seal failure prediction from cracks, leaks, or deformation, allowing a better-designed product or reverse-engineering of existing...
I Test Purpose To verify the pressure cycling performance of the gate valve stem packing seals at 15000PSI, -50~350℉. II Product and fixture 1. Product structure The seals include 1 of A ring, 1 of spring, 1 of U ring, 1 of B ring, and 1 of C ring, see fig. 1: 2. Material : 1-PTFE+13% Carbon fiber+2%Graphite (PC007) 2-PTFE+13% Carbon fiber+2%Graphite (PC007) 3-Elgiloy Golden 4-PTFE+13% Carbon fibe...
Well Service Fracturing Pump Packing Seals are commonly used in high-pressure mud pumps and fracturing pumps, as a high-speed reciprocating dynamic seals. Its main function is to prevent plungers from leakage in high-speed reciprocating. Some special working conditions are taken into consideration when designing its structure and material, which make it apply to fracturing fluid, mud mediums and s...
V-packings, also known as Vee packing seal and Chevron V-packings, or V stack, is a kind of stacked seal. It is combined by a male adapter, a female adapter and a number of intermediate V rings. V-packings are designed to be used in applications such as hydraulic cylinders, fracturing pumps or well downhole. Facing different working condition (temperature, pressure, media), the raw material differ...
Guangzhou JST Seals has been supplying stem packing seal and seat seal for 6A gate valve for over 20 years. To give an unequivocal assurance of quality, performance and durability, our seal has been tested and witnessed by the third party DNV. The seal materials are PEEK+PTFE+Elgiloy Spring. Our seals are installed on Douson 3-1/16“ 15M Gate valve and 2-1/16'' 10M Gate valve and 1-13/16'' 15M Gate...
Fracturing pump seals,also known as plunger pump packing or plunger packing seal, are mainly applied in fracturing trucks, mud pumps and cementing trucks for oil industry of harsh working conditions. The fracturing pump seals are combined with Top Adapter, Bottom Adapter and Pressure Rings. The number of the pressure rings is flexible, which allows the seal sealing at a wide range of pressures und...
JST Seals can provide vee packing manufactured from its range of high performance elastomers, PTFE and PEEK. Typical applications include mud pump packing, where the seal encounters high pressure and grinding media containing various solids, oil and water. 1. Test purpose The objective of this test procedure is to evaluate the quality of JST non elastic seal, V-Packing seal stack design as p...
Plunger pump packing is the sealing device of plunger pump, which is mainly a protective device to prevent the liquid at the hydraulic end from flowing out and improve the operation efficiency. JST Seals has developed high performance well service pump packings to provide maximum sealing for high-pressure oil well service pump. As the plunger pump is a high-pressure machine pump, and the temperatu...
