Trenchless drill pipeIt is mainly used in horizontal directional drilling pipeline crossing and laying engineering, and the pipe body is in accordance withAPIStandard special materials, stable performance, unique drill pipe joint twice thickening forming technology, the transition zone is smooth and smooth, reducing mud passing resistance. The liquid nitriding treatment of the joint thread penetrates deeper than the traditional process and has a higher surface hardness. Using large numerical control lathe, double shoulder high torsion joint thread adopts internal and external composite shoulder structure design, the tight distance of thread processing is strictly guaranteed, with higher tensile strength and torsion yield strength, all threads are equipped with thread gauge in line with international standards, so the quality of the drill pipe produced is stable and reliable.

power up to trenchless drill pipe type:60,73,83,89The length can be customized according to customer needs. Trenchless drill pipe material steel grade isS135Model, guaranteedTrenchless drill pipeThe quality.
