The application of thick-walled seamless steel pipes in pipelines in recent years is very large, and it can be said that there are huge applications. In pipeline applications, because of the large amo...

(1) The geometrical characteristics of the straight seam steel pipe section are good, the pipe wall is generally thin, the section material is distributed around the centroid, the section has a large ...

The reason for the corrosion of the stainless steel seamless pipe was analyzed except for the atmosphere inside, the oxide tube of the oxide film of all metals in the oxygen. Unfortunately, the iron o...

Hot reheat steam pipeline; three of the four major pipelines: cold reheat steam pipeline (two high temperature and high pressure steam pipelines between the high pressure cylinder exhaust port and the...

Stainless steel welded pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial conveying pipeline...

Because they are stacked outdoors, and most of the steel pipes are buried in the ground, they are easy to corrode and rust. In order to ensure the smooth flow of the pipe, the spiral submerged arc pip...

According to the material science point of view, the chemical composition, physical properties, and geometry of a good metal material should be continuous, pure, and uniform. If these three aspects ar...

Introduction to the cold drawing method of common steel pipes: production of high-precision cold-drawn pipes - hydraulic cylinders compared with traditional cutting processes, with the following chara...

Straight seam submerged arc welded pipe is widely used. At present, the application of LSAW has been extended to many fields. In addition to oil and gas long-distance pipelines, it has also developed ...

1. Tensile strength (σb): The maximum force (Fb) received by the sample during the stretching process, pided by the original cross-sectional area (So) of the sample (σ), is called Tensile strength (σb...
