LINER, FLUID END PARTS, 6-1/4", API SPEC 7K STANDARD, MUD PUMP SPARE PARTS BI-METAL / ZIRCONIA CERAMIC TYPE

Bi-metal Liner of Mud Pump Spare Parts
Material: The material of cylinder liner is ZG45 steel, lined with high chromium cast iron.
The HRC of cylinder inside liner is 60-65;
Production Process: The bi-metal cylinder Liner of our company combined with the advantages of abrasion hot-forging out liner and anticorrosion high chrome inner liner.
The out liner is made of high quality carbon steel by hot pressing forming. Its tensile strength is over 900000psi.
The inner liner is made of high-chromium alloy by centrifugal casting.

Zirconia Ceramic liner of Mud Pump Spare Parts

* Suitable for deeper oil reservoir,bad drilling geological structure environment,offshore oil and gas development.
* Service time is 5-10 times than bi-metal liners.The using time of liners are up to 6,000 hours.
* The material of ceramic liners is the increased flexible zirconium ceramic.These liners feature wear resistance,high anti-corrosion,high temperature resistance,high pressure,high intensity and high hardness.
* Reduced the freight cost,maintenance cost,labor cost and storage cost of oil drilling.
* Zirconium ceramic liners have better performance than alumina ceramic liners such as more toughness,longer service life,saving water lubrication,reducing wear of piston.
