High Steel DTH Drill Pipes for Rock Drilling Tools,steel drill pipe,mild steel pipes

The priority choice of pipe body is TPCO according to the customer requirement, the min. wall thickness of the body is 95% WT.

We purchase the drill pipe body according to the PSL-3 standard, the impact value (10*7.5*55) -20°C shall meet the average impact ＞80J；the single impact value ＞ 64J. Length and radius of upsetting transition zone shall meet the NS-1requirement, inner transition μ ＞100mm；transition R ＞300mm.

Pipe ends apply the large-ton hydraulic upsetting, with big strike power and shaping speed,the size and structure of the pipe end are reasonable.

Continuous upsetting avoid the risk of coarse grains after reheating and cooling for many times.

,prevent failure of drill pipe in advance because of pierce.

Speedy Upsetting -the greatest advantage of using the large-tonnage hydraulic upsetter is high speed , which can refine the grain well, ensuring the pipe ends with good mechanical performance after heat treatment and forging, and together with the upset part ,are both consistent with performance of mother pipe. This is better workmanship for drill pipe manufacturing and drilling operation, offering good solution to drill pipe manufacturing especially the mechanical performance of weld line.
