Piston Rods for Triplex Mud Pumps, F-sries, GD series, National
Our piston rods is made of 40Cr or 42CrMo after forging and
normalizing. They have high mechanical strength, high tensile
strength, good shock resistance.
Piston Rods for Duplex Mud Pumps FY-FXD,.......
This piston rod has two kinds, one is: thermal refining and high
frequency, the other: thermal refining, high frequency and
The hardness reach to HRC58-62, Each liner is highly degree of
finish. Especially after plating chromium the piston rod has a
strong corrosion resistance and wear resistance. At present our
piston rods, such as API 1# 3# 4# 5# 6#, have high mechanical
strength, good stability. Our products export with locknut, well
received by users.
