product description



Mud hog pump is the "heart" of the oilfield drilling system, and mud pump liner is an important vulnerable parts of mud pump fluid end. The service time of oil drilling mud pump will be directly affected by service time of mud pump liner.

Mud pump cylinder liner will contact with the high-temperature, high-pressure gas directly, and mud pump piston ring makes a high-speed reciprocating motion on the surface of the liner, which determines that the mud pump liner not only has sufficient strength and rigidity, but also must withstand high temperature, corrosion resistance and wear resistance.

NO. Liner Type Liner Introduction Features
1 Ceramic Liner Adopt the most advanced international toughened zirconium. Value of fracture toughness is K10~15MPa, value of resist-bent strength is σ600~800Mpa. Ceramic Liners can not only adapted to some tough environment such as deep oil reservoir, hard stratum and severe earthiness, but also can be used for offshore oil and natural gas exploitation. With advantages of wear-resistance, erosion-resistance, high pressure resistance, high temperature- resistance, high strength, High thermal ratings and high hardness.
◎Reduced the cost of shipment, maintenance, labor and storage in the drilling works.
◎With better toughness properties and longer service life.
◎Reduced piston wears and water consumption for lubrication.
2 Bi-metal Liner It combines a forged wear-proof outer sleeve and a wear resistant and corrosion resistance inner sleeve with high chromium iron. After heat treatment, high chrome iron inner sleeve can reach a hardness of HRC≥61~64. It’s warmly welcomed by many oil-fields at home and abroad. ◎High temperature- resistance, high strength, High thermal ratings and high hardness.
◎Reduced the cost of shipment, maintenance, labor and storage in the drilling works.
3 Mono-metal Liner Carbon layer’s quenching thickness of inner bore reaches 1.5-1.8mm and hardness 58-60HRC ◎ Have characteristics of high hardness, high corrosion resistance, free of deformation and best surface finish
