According to different conditions, the metal material is heated to a suitable temperature and kept warm, and then cooled in different ways to change the metallographic structure of the metal material and obtain the required structural properties. This process is usually called metal material heat treatment. What three processes are included in the heat treatment of seamless tubes? Heat…

Read MoreBoiler tube is a type of seamless tube. The manufacturing method is the same as that of seamless pipes, but there are strict requirements on the steel grades used to manufacture steel pipes. According to the temperature of use, it is divided into two types: general boiler tubes and high-pressure boiler tubes. The mechanical properties of boiler tubes are…
Read MoreSteel pipe structures currently used in engineering can be classified according to cross-sectional shape, structural form and manufacturing method. According to the cross-sectional shape of the component, the steel pipe structure can be divided into three categories: the circular tube structure (CHS), the square (rectangular) tube structure (RHS) and other shapes. Due to the superiority in appearance and mechanical…

Read MoreIn the casting and rolling process of seamless steel pipe, one of the important technical indicators to measure the processing quality of seamless steel pipe is straightness. Most seamless pipes need to be straightened, and the oblique roller straightening has high work efficiency and is in the main position. However, for the bending deformation of steel pipe ends and…
Read MoreHot-dip galvanized seamless tube is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in the…
Read MoreIn the process of smelting or hot working steel, due to certain factors (such as non-metallic inclusions, gases, and improper process selection or operation, etc.). Resulting in defects in the interior or surface of the seamless tube, which will seriously affect the quality of materials or products, and sometimes lead to scrapping of materials or products. Looseness, bubbles, shrinkage…
