O ring is an annular rubber seal with a circular cross section, mainly used in mechanical parts in static conditions to prevent the leakage of liquid and gas. In some cases, O ring can also be used as the dynamic sealing element in axial reciprocating motion or low-speed rotational motion. O ring provides as an effective and economical sealing element in different types of static or dynamic seal a...

Packer elements are rubber seals that operate under specific down-hole conditions and provide an elastomeric seal for either short-term or long-term completion. Packer elements are used between sections of oil and gas production tubing to prevent fluids and pressure from leaking through the joints. This protects the casing, production tubing, liner and wellbore wall above and below the p...

With the development of fracturing and acidizing application technology, fracturing pumps with high pressure and large flow are required. The working condition of fracturing pump is extremely bad: high pressure, high acidity, high sand content and high sand hardness. Poor working conditions make the service life of the plunger pump seals short and the maintenance frequent. Sometimes, the seals mad...

1. Tensile property of valve stem sealing material Tensile property is the first property to be considered for sealing materials, including tensile strength, constant tensile stress, elongation at break and permanent deformation at break. The tensile strength is the maximum stress at which the specimen is stretched to fracture. The constant elongation stress (constant elongation modulus) is the st...
