Outer Diameter: 76mm
Length: 1000-5000mm
Wall Thickness: 5-6.5mm
F/M Thread: 2-3/8" API Reg.
Material: threaded connection 42CrMo, drilling pipe R780
Process: adopt thickened treatment to reduce drill pipe weight 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 ends of the pipe body feature thickened sections that significantly enhance weld strength. After friction welding, the components undergo a tempering process to ensure the quality and performance of the drill rod and effectively extend the service life of the equipment.
DTH drilling pipes are used for connecting DTH hammers and drilling bits. Manufactured from seamless steel tubing, they are the key accessories for all types of DTH drilling operations, playing a critical role in operation. High-quality drilling pipes combine exceptional durability, precision, and outstanding operability, ensuring efficient drilling operations.
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.
