What is Cast Iron Triplex Mud Pump Accessories Liner?
Cast Iron Triplex Mud Pump Accessories Liner Steel Integral Forging
Mud Pump Liner combine the strength of a forged steel outer shell
with the abrasion and corrosion resistance of a high chrome inner
sleeve. These liners feature a centrifugally cast high chrome iron
sleeve which is machined and heat treated to a minimum uniform bore
hardness of 59-65HRC.
Cast Iron Triplex Mud Pump Accessories Liner Steel Integral Forging
Mud Pump Liner is the main expendable parts of the mud pump, it
adapts double metal fix together.Bi-metal cylinder liner is one of
the most widely and largest used mud pump fluid end fittings.
Mud pump liners are including Bi-metal Liners and Ceramic Liners.
Sizes of 6 1/2”, 7”, 140mm, 150mm,160mm, 170mm, 200mm, 230mm
liners.
The material of most Bi-metal cylinder liner is ZG45 steel, lined
with high chromium cast iron. The HRC of cylinder inside liner is
60-65;
What is the production process for Cast Iron Triplex Mud Pump
Accessories Liner?
The Cast Iron Triplex Mud Pump Accessories 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.
Whta are the general features for Cast Iron Triplex Mud Pump
Accessories Liner?
The outer sleeve is forged steel with quality carbon steel,the
inner sleeve is casted with high carbon and high chromimum use the
technology of centrigual casting, after treatment ,the hardness of
it can reach to a level of 59-67HRC.
Liner Outer Sleeve: 45# forged steel,tensile strength is δb ≥610Mpa
,yield strength is δs≥450Mpa,elongation hardness is E≥17%,hardness
is HRC180-200.
Liner Inner Sleeve :high chromium cast iron(centrifugal forged).
Annealing hardness is HRC≤ 40.Quenching hardness is HRC59-67.
Chemical Composition C 2.8%-3.1% Cr 26%-28% Si 0.6%-0.9% Mn 0.5%-1%
Mo 0.5%-0.8% S.P≤0.05%.
What is Ceramic Liner?
Ceramic Liners combine the strength of a forged steel outer shell
with the abrasion and corrosion resistance of a ceramic inner
sleeve.
Ceramic cylinder inner sleeve is used zirconia toughening alumina
ceramics obtained the national patent, using zirconium oxide the
characteristics of high fracture toughness and high hardness of
alumina, the combination of these two can improve the fatigue
strength of the product. Its coat uses 45 steel forging with good
mechanical properties.
After tempering heat treatment, hardness of HB235-265, the tensile
strength is not less than 655 mpa.
