Valve body
In order to meet the need of modern petroleum drilling technology, new mud pimp fittings were deceloped byQingdao zhifeng petroleum equipment co.,ltd through cooperation with china petroleum university(huadong) which have good properties of hightemperature, high pressure resistance, high antifriction and anti sulfur corrosion.
High quality alloy steels above petroleum standard such as 20CrMnTi, 20CrMnMo, 20CrNiMo and 20Cr2Ni4 were used to make the valve assembly, and newly developed high molecular materials to make the mud pump fittings in order to resist high-temperature, high-pressure, anti friction and sulfur corrosion. The valve assembly manufactured by tsingtao zhifeng petroleum equipment co.ltd ranks the international topclass level!
