Geological Drilling Pipe

Geological tube is steel pipe that using core drilling for the geological department, which a hollow cross section, surrounded by long geological drilling joints with steel pipes.

Geological Drilling Pipe

Geological pipe (YB235-70) with a hollow cross section, a large number of pipes, for conveying fluids such as the transportation of oil, gas, gas, water and some solid materials, pipes, etc. By end-use can be divided into the drill pipe, drill collars, the core pipe, casing and precipitation tubes.

Drill Pipes with Welded Tool Joints

To explore the underground rock structures in the practical application of geological tubes, geological drilling pipe, groundwater, oil, gas and mineral resources, the use of rigs drilling wells. Oil, gas, mining can not be separated from the drilling wells, geological drilling and oil drilling seamless steel pipe, drilling equipment, including the core outer tube, core tube, casing, drill pipe.

Drilling tube deep into the depth of several kilometers strata, the working conditions are extremely complex, the drill pipe to withstand tension and compression, bending, torsion, and the uneven impact load stress, but also by the mud, rock wear, therefore, the requirements of the pipe must have sufficient strength, hardness, wear resistance and impact toughness.

Tech & Service of Seamless pipe

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.

How to make seamless pipe(seamless pipe process)?
Hot Piercing Workshop
Piercing process
The cross roll piercing and pilger rolling process in the size range from approx. 250 to 660 mm outside diameter.
Precision cold drawn steel tube production process
Pipe weld cracks
often follow different mechanisms can be divided into two types of thermal cracking and cold cracking.
How to calculate a steel pipe and tube theoretic weight
Calculate a steel pipe?
Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe.
Pipe beveling
Pipe beveling is the process where an angle is formed between the edge of the end of a pipe or tube and a plane perpendicular to the surface.
Steel pipe cutting machine
Pipe cutting
Cutting tools have a grinding wheel piece cutting machine (also known as toothless saw), hand saw, cutter and other hand tools.
Packing the steel pipes
There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method.
