Description:

1. Select high quality carbon steel as material.

2.After plating chromium, inside surface hardness reachs to HRC66-72 with good abrasion resistance. Clad layer and basal body joint tightly without any porosity, sand holes and crack.

3.It solves many questions like anticorrosion, acid proofing, alkali prevention and antiscale etc. Can be used in wells with sand, water and mild corrosive medium.

4. Greatly reduce oil field work frequency and cost.

5. At present, we can provide service of plating Cr and honing for series of pump barrel.
