4" BECO thread with 6 1/2" OD Blast Hole Drill Pipe For Altas Copco DML Rig
BECO 4" Thread 6 1/2" OD Blast Hole Drill Pipe For Gardner Denver GD45-B
Rotary drill pipe products are processed from high-quality materials, and the heat treatment of the materials uses multi-functional integrated heat treatment equipment. All thread processing uses professional numerical control processing equipment, and all thread processing and testing are equipped with professional thread gauges that meet international industry standards. Therefore, the thread fits closely and maximizes the thread fit quality.
The drill pipe welding method adopts two methods: submerged arc welding or friction welding. Compared with ordinary welding methods, submerged welding has a deeper penetration and good weld quality after welding. However, friction welding can achieve the strength of welding material and base material, high welding efficiency, stable quality, good consistency, and can realize welding of dissimilar materials. Therefore, the quality of the drill rod is stable and reliable, and the service cycle is greatly extended. The use of the secondary drill rod can make loading and unloading fast and convenient, and reduce the drilling time.
