Inner Tungsten Alloy Galvanizing (ITAG)  Tubular     Inner Tungsten Alloy Galvanized Drill pipe   The ITAG carry out outstanding performance in fighting back the friction, scaling, scouring when drilling and pumping, and get used in high pressure and high temperature in deep wells, acid and alkaline circumstance. By galvanization, the tungsten alloy well integrated with the steel, resolve the problems such as the erosion, abrasive, and furring.     Tungsten Alloy Galvanized Sucker Rod The ITAG technology has been successfully applied on tubing and casing, drill pipes, and sucker rod, normally, it increased the life of tubing by 3-4 times, reduce the cost of drilling and oil produciing greatly   Inner Tunsten Alloy Galvanized Tubing.
