Now stainless steel capillary tube is widely used, but stainless steel capillary tubes will have oil stains, oxide scale produced by welding, and some other dirt during the production process. If there is an oil stain, it can be cleaned with an organic solvent or alkaline solution. If it is rusty, i

Thin-walled stainless steel pipes rely on a very thin but extremely strong, dense, and reliable chromium-rich oxide protective film on the surface to prevent oxygen atoms from penetrating the steel pipe, thereby obtaining anti-oxidation properties. However, in some cases, this film is continuously d

X60N seamless steel pipe is a high-strength, high-toughness steel pipe widely used in oil, natural gas, chemical, power, and other industries. Its seamless structure gives it high pressure bearing capacity and excellent corrosion resistance, which can meet the use requirements in various complex env

What are the inspection items for seamless steel pipes? First of all, seamless steel pipes are made by perforating a whole round of steel. There is no weld on the surface of the steel pipe, which is called a seamless steel pipe. According to the production method, seamless steel pipes can be divided

Common methods for testing the mechanical properties of seamless steel pipes mainly include tensile tests and impact tests. The principles of these test methods will be explained below, and how to obtain key mechanical property parameters from test data will be explained.1. Tensile test: Tensile tes

Rectangular steel pipes are in continuous production, especially in the welding process, which has a considerable impact on the quality of rectangular steel pipes, so the welding techniques we often see are automatic welding and manual welding. Automatic welding generally uses submerged arc welding

API 5L GRB seamless steel pipe is a kind of pipeline material widely used in the transportation fields of oil, natural gas, etc. Its excellent mechanical properties and corrosion resistance make it the preferred material in many engineering projects. This article will introduce the characteristics,

Before discussing the broad application and exquisite craftsmanship of stainless steel seamless pipes, let us first unveil its mystery and take a glimpse of this key role in the modern industrial field. Stainless steel seamless pipe, as the name implies, is a seamless tubular product made of stainle

Decarburization is the phenomenon in which the carbon content on the surface of a steel pipe decreases during heat treatment. The essence of decarburization is that the carbon atoms in the steel pipe react with the furnace atmosphere such as hydrogen or oxygen at high temperatures to generate methan

Steel plate delamination and cold brittle cracking after steel plate fire cutting and welding generally have the same manifestation, both of which are cracks in the middle of the plate. From the perspective of use, the delaminated steel plate must be removed. The whole delamination should be removed
