Seamless line pipe is mainly used to transport high pressure oil and gas near the wellhead. With the increasing problem of hydrogen sulfide corrosion, the development of sulfur-resistant seamless line...
The main innovative achievements of high-strength plastic seamless steel pipe are as follows:(1) The continuous cooling phase transition behavior of 0.16C-0.31Si-1.6Mn microalloyed steel was studied...
The following is the installation process of longitudinally submerged arc welding pipeFirst, the process of installation preparation - rolling groove -> opening, installation of mechanical three-way...
Seamless steel pipes are used primarily in pipeline transportation and can be used to transport some fluids, for example, some power, etc. Oil and gas are now available for some groundwater...
A world without seamless steel pipes is something that no one can imagine, and is unacceptable to all. It is because it has better compression resistance than ordinary steel pipes, so it can become an...
First, control the C content. Matching the electric furnace with refining is an effective means to achieve precise control of the C content. Strictly control the C content at the end of the electric...
LSAW Steel Pipe Technical Features1. In the process of steel tube forming, the steel plate is uniformly deformed, the residual stress is small, and the surface is free of scratches. The processed...
The extrusion of seamless steel tubes is an essential part of the production process. The extrusion method of large-diameter seamless steel pipe and small-diameter seamless steel pipe is basically the...
Intergranular corrosion of stainless seamless steel pipe is a common type of partial corrosion. Corrosion is carried out along the metal or alloy grain gap or its close area, and the grain corrosion...
The bruising of the large-diameter seamless steel pipe surface in the reheating furnace is also a common defect. It is mainly because it is on the tapping roller of the step-type reheating furnace or...
Oil casing and oil drilling can not be separated from oil casing. Although steel pipes commonly used in construction have little mention of oil casing, it has been found by professionals that the...
In the application process, the welded pipe is very different from the seamless steel pipe. The main stress direction of the spiral steel pipe, that is, the axial direction of the steel pipe is...
Seamless steel pipes are generally produced by hot rolling technology. If they are distinguished by units of measurement, it is generally considered that a wall thickness to the diameter of a seamless...
Reverse bending performanceAccording to the requirements of the buyer, the steel bar of SSAW steel pipe can be tested for reverse bending performance.In the reverse bending test, the diameter of the...
Precision seamless steel pipes expansion coefficient: The method of inspection can be applied to the joint gap of the annealing furnace with soapy water to see if it runs out of gas; the most easy...
