ZJGH 4''-5000PSI(10, 000PSI) drilling fluid manifold consists of mud gate valve, high pressure union, tee, cross, elbow, high pressure hose, pup joint, pressure gauge, etc. The ground valve group adopts the good\se shaped tee structure, compact and low in fluid resistance. The rig valve group adopts adaptor spool, which can be directly used as a single pipe on site. The high pressure union is made of high strength alloy steel and heat treated. The gate and valve seat are spray welded with hard alloy, which prolongs the life of the valve, reduces the operation torque and provides easy opening. The elbow, adaptor, tee and cross, etc are made of high strength alloy steel and heat treated. The wall thickness is increased to meet the demands of high strength and corrosion resistance. For parts with high precision requirements, special processes are adopted to guarantee the quality. All high pressure bearing parts are hydrostatic tested for strength and seal tested before assembly to ensure quality before delivery.
