The chrome internally plated barrel is fabricated from carefully selected carbon steel material(1045, 1026) and Inhibited Admiralty Brass (C443) and has a uniform thickness of chrome plating is added on the I.D., offering resistance to abrasive sands and foreign materials. It has exacting tolerances conforming to API dimensions.
Chrome-plating Barrel Feature:
1. Uniform plating, high bonding strength, accurate dimensional precision
2. The inner bore hardness up to HV900-1160, small friction coefficient and good wear resistance, can be used for sand and other friction medium oil Wells
3. Good chemical stability, no action in alkali, sulfide, nitric acid and most organic acids, and excellent corrosion resistance
