To store seamless pipes, choose a suitable site and warehouse

There are many factors affecting the drawing force in the drawing process of stainless steel pipes. According to the research, some of these factors are beneficial to the drawing process. On the contrary, other factors increase the difficulty of stretching. The drawing process and the performance of the drawn metal, heat treatment, deformation of each pass and drawing speed. The friction between the waste tube and the mold, lubrication, geometric dimensions and mold shape are closely related.

Galvanized steel pipe has the dual advantages of strong corrosion resistance and low price, and its usage rate is getting higher and higher. However, in some cases, it is necessary to weld the galvanized pipe. How to ensure the quality of welding?

Stainless steel has good comprehensive performance and good appearance and surface characteristics, and is widely used in various industries. Similarly, stainless steel pipes are no exception.

Large-diameter straight seam steel pipe is a welded steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. It is usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on.

Steel pipes are divided into seamless pipes and welded pipes according to whether there are welds or not. A seamless pipe is a long strip of steel with a hollow section and no seams around it. Welded pipe is a steel pipe made of steel plate or strip steel after being crimped and welded.
