Carbon steel seamless tube is divided into: 1. Low carbon steel seamless tube Low carbon steel tube is carbon steel with a carbon content of less than 0.25%, including most ordinary carbon structural steels and some high-quality carbon structural steels, most of which are used for engineering structural parts that do not require heat treatment. Some are also carburized…
Read MoreSurface processing of seamless tubes (smls) mainly includes: steel tube surface shot peening, overall surface grinding and mechanical processing. Its purpose is to further improve the surface quality or dimensional accuracy of steel tubes. Shot peening on the surface of seamless tube: Shot peening on the surface of steel pipe is to spray iron shot or quartz sand shot…
Read MoreThere are two categories of factors that affect the quality of seamless tubes: steel quality and rolling process factors. Many factors of the rolling process are discussed here. The main influencing factors are: temperature, process adjustment, tool quality, process cooling and lubrication, removal and control of sundries on the surface of rolled pieces, etc. 1. Temperature Temperature is the…
Read MoreThe uneven wall thickness of the seamless tube(SMLS) is mainly manifested in the phenomenon of uneven wall thickness of the spiral shape, uneven wall thickness of the straight line, and thicker and thinner walls at the head and tail. The influence of continuous rolling process adjustment of seamless tubes is an important factor leading to uneven wall thickness of…
Read MoreThe seamless tube is formed in one piece, directly pierced from round steel, without welds on the surface, and has a wide range of applications. Because of the special processing of seamless steel tubes, carbon structural steel, low alloy structural steel, etc. are generally used for production, and its output is large, and it can also be customized according…

Read MoreSeamless boiler tube is a kind of boiler tube and belongs to the category of seamless steel tube. The manufacturing method is the same as that of the seamless tube, but there are strict requirements on the steel type used in the manufacture of the steel pipe. High-pressure boiler seamless tubes are often under high temperature and high pressure…
Read MoreIn daily life, people always refer to steel and iron together as “steel”. It can be seen that steel and iron should be a kind of substance; in fact, from a scientific point of view, steel and iron have a little Different, their main components are all iron, but the amount of carbon contained is different. We usually call…
