Jinan Hongyang manufactures high-chrome, zirconia, and
hardened steel liners for all major brands of mud pumps. We have
liners for both duplex/triplex mud pumps. The liners we manufacture
meet or exceed OEM specifications and API standards.
Chrome-Plated Liners are made from premium forged steel with
the core plated by .***-.**5" chrome, and have hardening
characteristics of *8 to *2 Rockwell C hardness.
Hy-Chrome Liners are heated treated to ****5 RC hardness with
micro-finished honed ID to ensure piston durability. Liner bore
tolerances are tighter than API specifications, and give
approximately ***0% bonus hours of service life to the piston and
liner.
Zirconia Liners are made from zirconium and oxygen, which is
stabilized in the cubic crystal structure and avoids cracking and
mechanical weakening during heating/cooling for long life.
Hardened Steel Liners are made with premium forged steel in
which the bore is carburized and quenched creating a hardened layer
with hardness of *8 to *2 Rockwell C scales from abrasion and
corrosion.
