Our single-acting piston rods are forged of quality alloy steel, and made via normalizing. They have high intensity, shock resistance and long service time.

We produce great variety of double-acting piston rods. They are manufactured precision, export large quantities, and widely used in GD series mud pumps.  

This piston rod has two kinds, one is: thermal refining and high frequency, the other: thermal refining, high frequency and chroming.

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.
