RGD is known as Rapid Gas Decompression, AED is known as Anti-Explosive Decompression. RGD (Rapid Gas Decompression) or AED (Anti-Explosive Decompression) is a failure mechanism of O-rings and elastomer seals which is caused by the rapid reduction in pressure of the gaseous medium. When the pressure is released, the gas penetrating into the elastomer seal will expand violently, which in turn will ...

Spring energized seal, also called spring loaded seal can select V-shape, H-shape or C-shape spring forms and sealing lip design according to various applications such as dynamic and static or internal and external pressure, so as to produce different sealing force and compressible deformation (see the following figure: spring deformation / elastic curve). The spring force will affect the performa...

Packer elements refers to a downhole tool seal connected to the downhole string and used to seal the annular space between tubing and oil and gas well casing or open hole wellbore. In oil production engineering, the packer is used for layering, and an oil production channel is designed on the packer. When setting, the piston sleeve goes up and the oil production channel is opened; After setting, t...

P seal is constructed from an elastomer with back up rings for anti-extrusion. Energized by the injection of sealant, it is a static seal that is used to seal rough casing and tubing. Backup rings are available in Mesh Stainless Steel or Solid Carbon Steel. The standard P Seal is a one-piece molded seal utilizing molded-in anti-extrusion device. This design enhances assembly by eliminating the loo...

Spgo seal, also known as glyd ring, is a low friction piston seal, which improves the perfect combination of sealing performance and service life by optimizing contact pressure and reducing the heat generated by friction. The D-section of this seal combines two special groove designs to maintain sufficient lubricating oil film between the seal and the contact surface, which can ensure sufficient f...
