Detailed Description

mud pump parts high pressure valve assembly In order to meet the need of modern petroleum drilling technology, new mud pimp fittings were deceloped by Qingdao 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! Our company is the original factory in Qingdao Petroleum Machinery Factory, July 2007 through the ISO9001(REGISRATION NO.0885) international quality system certification, and in 2008 passed American petroleum institute quality management system of preference API SPEC Q1 (REGISRATION NO.Q1-0637) and ISO/TS 29001(REGISRATION NO.TS-0469) authentication. First set Main part materials: 20CrMnTi, valve seal ring: JSR-220S. Characteristics: ordinary anti-impaction and anti-compression property Application: pump pressure around 18MPa, temperature of cycling mud≤60°C Second set Main part material: 20CrMnTi, valve seal ring: polynurethane or polyether ester Characteristics: good anti impaction property, ordinary temperature tolerance, poor anti hydrolysis property Application: pump pressure around 20mpa, temperature of cycling mud≤80°C Third set Main part material: 20CrMnMo, Valve seal ring TPF-2 Characteristics: excellent anti impaction, abrasive wear and sulfur corrosion property, good strength at 80-150°C Application: pump pressure 20-30MPa, temperature around 120°C Fourth set Main part material: 20CrNiMo or 20Cr2Ni4, valve seal ring: TPF-3 Characteristics: excellent anti impaction and high temperature tolerance property, Application: high pressure and high temperature and pump F-1600HL, F-2200hl, excellent anti sulfur corrosion.
