Quality inspection method of seamless steel pipe: (1) Geometric specification detection of seamless steel pipes The diameter, thickness, bending degree, and length of the seamless steel pipe can be inspected on the inspection table with external calipers, vernier calipers, bending level rulers, and length meters. For external opening diameter, thickness and length, automatic specification inspection equipment (such as automatic…
Read MoreGenerally, manufacturers have the following requirements for their quality when producing seamless pipes. 1. Ingredients. It clearly stipulates the components of hazardous chemical molecules As, Sn, Sb, Bi, Pb and vapor N, H, O, etc., in order to improve the uniformity of the components in the steel and the purity of the steel, and reduce the non-metallic material parameters…

Due to the error in the initial engineering calculation, a batch of elbows was not ordered. Now…
Read MoreSeamless steel pipe (smls pipe) is a non-combustible building material, which has the characteristics of earthquake resistance and bending resistance. In practical applications, seamless steel pipes can not only relatively increase the load capacity of buildings, but also meet the needs of architectural design aesthetic modeling, and also avoid the defects that concrete and other building materials cannot be…
Read MoreA lead screw is a slender, flexible workpiece. Because slenderness lacks sufficient rigidity and is easy to bend, bending and internal stress are important issues in lead screw processing. The current whirlwind milling process is still suitable, but it needs to be improved continuously, improve the level of existing equipment, and pay attention to solving the problems of tool…
Read MoreThe biggest difference between seamless steel pipe and other long strips is that there is no joint around it, and the section of steel pipe is hollow. Due to different cross-sectional shapes, it is often classified as circular steel pipe and heterosexual steel pipe. Of course, circular steel pipe is more common in terms of actual use efficiency. Wonder…
Read MoreSeamless steel pipes are often used as raw materials for ring-shaped metal material parts, which not only saves a lot of complicated technological processes, but also greatly reduces the wear and tear of stainless steel plates in the production process and saves product costs. The basic principle of this kind of production and processing is not difficult to understand….
Read MoreWhat are the processing methods of stainless steel welded pipe? What should be paid attention to in processing? Cold drawing deep processing: it is easy to generate friction heat, so the stainless steel pipe with high pressure resistance and heat resistance shall be formed at the same time. After processing, the oil attached to the surface shall be removed….
