Large hexagonal tube

The principle of selecting the heat treatment process of the drill rod made by the big six-party control: The criterion for choosing the heat treatment process is the degree of improvement of the actual service life of the drill rod.

Classification:

Steel for drill pipe and drill pipe

Key words:

Large hexagonal tube


Product Description

The steel used for drilling pipes for wells is a steel pipe used by geological departments for core drilling. It has high strength, good elasticity, is not easy to bend, and is easy to connect. It can be used in conjunction with various coal-fired electric drills or tunnel drilling rigs.The slag discharge is smooth and the accumulation of rock slag is reduced.

The process of making finished products from steel for drilling pipes for wells:

Iron ore is selected from steelmaking, continuous casting (mold casting), pipe rolling, pipe end thickening, pipe body heat treatment, tool joint manufacturing, friction butt welding, weld heat treatment to the finished drill pipe.
