Geological Drilling Seamless Steel Pipe,Seamless Steel Tube

Geological Drilling Seamless Pipes

Description

Geological drilling seamless steel pipe is a steel pipe used in core drilling for geological purpose. It has a hollow cross section. Therefore this seamless steel tube can be used for conveying fluids such as oil, gas, gas, water and some solid materials, etc. Products of this kind can be divided into the drill pipe, drill collars, core pipe, and casing and precipitation tubes. The seamless pipe is manufactured in accordance with GB/T 14975-2012.

Salient Performance

1. Geological drilling seamless steel pipe can be used in deep strata of several kilometers where the working conditions are extremely complex.
2. This seamless steel tube is capable of withstanding tension and compression, bending, torsion and uneven impact load stress. The steel pipe has sufficient strength, hardness, wear resistance and impact toughness.
3. This product features compact structure, reliable performance and easy operation. We can supply geological drill pipes of high quality at low price.

Application

Geological drilling seamless steel pipes are used in geological drilling. They are made of steels of DZ40, DZ50, DZ55, R780 and DZ60 Grades.
