Application of high-precision cold drawn tubes in China
China’s high-precision cold drawn tube, the first to be widely used in the coal industry, and now it has been extended to the manufacturing engineering industry, oil, cylinder, cylinder and piston rod. Drawing quality, efficiency, more and more high, production is also increasing, with the ...Read more -
How to solve the deformation problem of spiral seam submerged arc welded steel pipe
The spiral seam submerged arc welded steel pipe is drilled in rotation and begins to enter the soft formation. Under the action of the tri-cone, the drill first produces elastic shear deformation of the stratum and then is removed under the pressure of the tri-cone. In the simulated environment, ...Read more -
Working principle of spiral seam submerged arc welded steel pipe
The spiral seam submerged arc welded steel pipe is drilled in rotation and begins to enter the soft formation. Under the action of the tri-cone, the drill first produces elastic shear deformation of the stratum and then is removed under the pressure of the tri-cone.

The difference between hot simmering elbow and cold simmering elbow
The process is as follows: After the straight pipe is cut, the induction loop is put on the part of the steel pipe to be bent through the bending machine, and the pipe head is clamped by the mechanical rotating arm, and the induction loop is passed into the induction loop to heat the steel pipe. ...Read more -
What is the difference between cold drawn steel pipe and hot rolled steel pipe
(1) The difference between hot working and cold working: hot rolling is hot working, and cold drawing is cold working. The main difference: hot rolling is rolling above the recrystallization temperature, cold rolling is rolling below the recrystallization temperature; cold rolling is sometimes he...Read more -
Technical characteristics of double-sided submerged arc welding spiral steel pipe
1. During the forming process of the steel pipe, the steel plate deforms evenly, the residual stress is small, and the surface does not produce scratches. The processed steel pipe has greater flexibility in the size range of steel pipes with the diameter and wall thickness, especially in the prod...Read more
