Mud valve, high pressure spherical union, high pressure core union, tee , high pressure hose, elbow, pressure gauge, and pup joint etc.

Ground valve-group adopts gooseneck type tee with compact structure, little fluid resistance and large power effectuality. Adaptor spool adopted on rigid valve-group can be directly used as single pipe on site.

The high pressure unions are made from high-strength alloy steels and heat treated, featuring tight make-up and easy break-out. The special machine tool is used for the manufacture of the unions. The fine machined sphere and core work together with O-rings to provide sealing .

The sealing surfaces of both the gate and seat of the Z23Y-5000psi mud valve are built up using hard alloy overlays for erosion and corrosion resistance, which prolongs the mud valve’s service life, reduces the operating torques and makes the operation easy.

With the walls thickened as applicable and heat treated, the elbow, reducing pipe, tee and cross are made from high strength alloy steels and can fully meet the strength and corrosion requirements .

In order to ensure the product quality , the parts that require high precision are manufactured using special technology and all pressure-containing parts are hydrostatically tested prior to assembly .
