DTH Drilling Pipe O.D.89mm for Water Well

Outer Diameter: 89mm

Length: 1000-5000mm

Wall Thickness: 5-6.35mm

F/M Thread: 2-3/8" API Reg.

Material: threaded connection 42CrMo, drilling pipe R780

Process: Thickened treatment to reduce the weight of the drilling pipe while maintain weld strength.

Description

The down-the-hole drilling pipe is manufactured from quality materials, with heat treatment performed in an integrated multi-functional furnace. All threads are machined with specialized CNC equipment. The inner surface of the drilling pipe ends undergoes thickening treatment, significantly enhancing weld strength. Following friction welding, the components undergo tempering to ensure drilling pipe quality and performance, thereby effectively extending service life.

 

All DTH drilling pipes are manufactured with friction welding technology. Threaded connections typically comply with API standards, with special specifications available upon request, such as 2 3/8-inch, 3 1/2-inch API REG threads, and API IF threads. Customization is available to meet client requirements, with lengths ranging from 1000mm to 5000mm and outer diameters including 50mm, 60mm, 76mm, 89mm, 102mm, 114mm, 127mm, and 140mm.

Features

● The drilling pipe threads undergo nitriding treatment to enhance surface hardness and wear resistance.

● The main body of pipe adopts R780 material for improving overall wear resistance and strength. 

● Thickened design reduces overall drilling pipe weight while maintains weld seam strength integrity.
