(1) The scale of seamless steel pipe wall thickness masking is relatively wide, which can achieve small diameter and large wall thickness, but in general, the length is limited (only a small number of manufacturers can produce ultra long pipes); The wall thickness of stainless steel welded pipes can be relatively thin, which can achieve […]

304 stainless steel pipes have a long service life. From the application status of stainless steel pipes overseas, the service life of 304 stainless steel pipes can reach up to 100 years, or even 70 years, similar to that of housing construction.Of course, the prerequisite is that the quality of the 304 stainless steel pipe

Alloy steel pipe are divided into seamless pipes for structural purposes and high-pressure heat-resistant alloy steel pipe. Mainly different from the production standards and industry of alloy steel pipe, annealing and tempering of alloy pipes can change their mechanical properties. Achieve the required processing conditions. Its performance is higher than that of ordinary seamless steel

With the continuous progress of industrial technology, the demand for high-strength and corrosion-resistant materials is increasing. GH2132 seamless steel tube, as an important high-strength and corrosion-resistant material, has broad application prospects. This article will introduce the characteristics and applications of GH2132 seamless steel tube.GH2132 seamless steel tube is a nickel based alloy material with extremely

Austenitic stainless steel becomes soft after solution treatment. Generally, heating stainless steel fittings to about 950 to 1150 ℃ for a period of time promotes the complete and uniform dissolution of carbides and various alloy elements in austenite, followed by rapid heat treatment and cooling. Carbon and other alloy elements are too late to deposit

The production process of welded steel pipes includes steps such as cutting, chamfering, cleaning, docking, welding, polishing, etc. Among them, docking is one of the key steps, which requires the end faces of two steel pipes to be flat, vertical, and free of impurities and oxides. When welding, it is necessary to select appropriate welding

During the processing and production of precision carbon steel pipe, attention should be paid to various sizes. It is necessary to continuously enhance its performance advantages in production. Nowadays, precision carbon steel pipe pay more attention to size in production, which is the most basic and has better advantages. In its production and use, size
