Sucker Rod Pump Barrels are made of carbon steel, stainless steel and alloy steel; they go through strict controls from the reception of raw materials to the packaging inspection. Quality control is made to every manufactured part to ensure **0% compliance with API *1AX standard.
 

Pump barrel selects high quality carbon steel as material. After plating chromium, the inside surface hardness will reach to HRC****2 with good abrasion resistance. Clad layer and basal body joint tightly without any porosity, sand holes and crack.

 It has precise dimensions accuracy and can be applied to wells with sand, water and mild corrosive medium. It solves many questions like anticorrosion, acid proofing, alkali prevention and antiscale etc. Life expectancy has been increased by **3 times.

 It greatly reduces oil field work frequency and cost. At present, we can provide service of plating Cr and honing for series of pump barrel.
