F-1600 bimetallic cylinder sleeve
The bimetallic cylinder sleeve is one of the most widely used and most used hydraulic fittings of mud pump. The bimetallic cylinder sleeve combines the advantages of a hot forging high wear coat and a high-chromium wear resistant corrosion resistant inner sleeve. The coat adopts a high-quality carbon steel hot press and the inner sleeve is made of high-chromium cast iron centrifugal casting. The coat has a tensile strength higher than 900,000 psi., After heat treatment, the inner sleeve has a hardness of more than HC62 and can withstand the mud pressure of 7,000 psi. The inner surface is smooth as a mirror, and the size tolerance of the inner hole is strict. The normal service life can reach 800 hours or more.
Coat: 45 # forging, tensile strength σ B & GT; 610 MPa, yield strength σ s & GT; 450 MPa, extension rate <UNK> & GT; 17 %, hardness HB180-200.
Envelope: High Chromium cast iron(centrifuge casting), annealed hardness HRC ≤ 40, quenched hardness HRC 60-67.
The coat 45 # steel is forged to resist wear, and the inner sleeve is a ceramic lining, which is tightly bound by the inner and outer layers.
