Straight seam steel pipes are steel pipes with welds that are longitudinally parallel to the steel pipe. They are usually divided into metric electric welded steel pipes, electric welded thin-walled pipes, transformer cooling oil pipes, etc. The production process of straight seam welded pipe is sim

Anti-corrosion of large-diameter spiral steel pipelines means that when large-diameter spiral steel pipelines are used and transported, the pipelines are affected by the use environment and the transportation medium, causing chemical or electrochemical reactions to cause corrosion of the pipelines.

If the spiral steel pipe for water transportation is to transport tap water or drinking water, the inner wall is generally made of IPN8710 non-toxic anti-corrosion coating, and the outer wall is made of epoxy coal pitch anti-corrosion. Of course, it can also be coated with internal and external plas

Spiral steel pipe is a long steel pipe with a hollow cross-section and no seams around it. Steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water and certain solid materials. Compared with solid

The formation mechanism of "whitening" defects in steel pipe anti-corrosion coatings is due to the condensation of moisture mixed into the interior of the coating to emulsify and turn into a translucent white film. There are many reasons for it, such as air humidity in the construction environment,

Large-diameter flange is a kind of flange. It is widely used and promoted in the machinery industry and has been well-received and favored by users. Large-diameter flanges have a wide range of uses, and the range of use is determined according to different characteristics. They are mostly used when

The first thing that should be thought of to extend the service life of spiral steel pipes is to do a good job in its anti-corrosion work. Because pipes are mostly stored outdoors, they are most likely to rust when exposed to wind and rain, and thus suffer corrosion. The pipes can be processed and m

After stainless steel pipe fittings are processed by processes such as forming and welding, the metal molecular structure, magnetic properties, and physical properties change. The atmosphere-protected solid solution process can restore the corrosion resistance affected after processing, and at the s

The wave detection technology of straight seam steel pipe welds is a detection technology that has gradually emerged in recent years and is of great significance for improving the stability of straight seam steel pipes. Regarding the specific applications and common problems of wave detection of str

The use of stainless steel has become more widespread with the development of the economy. People are closely related to stainless steel in their daily lives. However, many people do not know much about the performance of stainless steel, and they know even less about the maintenance of stainless st
