What is butterfly valve Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. Butterfly valve refers to a valve whose closing part is a disc, which rotates around the valve shaft to achieve opening and closing. Types: - Double & triple eccentric, high performance HP butterfly valve, - Flange...

Oil and Gas pumping equipment is the lifeline of hydraulic fracking and drilling operations. When pumps go down for planned or unplanned repairs, productivity comes to a halt. JST sealing profile can make the equipment run longer and more efficient. Well Service Packing（ plunger packing seal） was developed to eliminate extrusion and provide excellent abrasion resistance for fracturing, acidizing, ...

The downhole tool sliding sleeve seal, we usually call it sliding sleeve or V stack, is a two-way elastic energy storage combination seal. It is a commonly used sealing element in downhole tools for oil production. When the sliding sleeve is pushed to the proper position, the sliding sleeve   activates the sealing function to seal off the upstream, so that the fracturing work can be carried o...

According to different materials, hydraulic rotary seals must have the following performance characteristics: 1. The seals has certain mechanical and physical properties: such as tensile strength, constant elongation strength, and elongation; 2. The material structure of the seals has a certain degree of elasticity, the hardness is verified, and the compression permanent deformation is small; 3.3....

Backup Ring (anti-extrusion rings) fit in the gland between the seal and the clearance gaps to provide zero clearance. Back-up rings provides additional resistance support to the seal and minimizes the risk of the seal being squeezed out of its housing under pressure. Although they do not be designed with sealing function in themselves. They used with o ring play an important role in whole sealing...

PEEK is a colorless organic thermoplastic semi-crystalline polymer with excellent mechanical and chemical resistance properties. It’s high-resistance to terminal degradation makes it useful in oil and gas environments. The processing conditions used to mold PEEK can influence the crystallinity and hence the mechanical properties. As with PTFE, PEEK has several benefits for oil and gas companies. I...
