The scope of application of seamless tubes in production and life is getting wider and wider. The development of seamless tubes in recent years has shown a good trend. For the manufacture of seamless tubes, it is also to ensure its high-quality processing and production. I will give you some brief introductions about the production process of seamless tubes…
Read MoreAccording 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 MoreIndustrial control of cold drawn precision seamless steel pipe production includes condition control such as die design, annealing, pickling, lubrication, etc. At the same time, capillary quality inspection and maintenance work should also be carried out. The production of cold-drawn precision seamless steel pipes requires attention to control: 1. Capillary: Pay attention to whether the thickness of the capillary…
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 MoreCarbon steel tubes are made of steel castings or solid round steel through holes to make capillaries, and then made by hot rolling, cold rolling or cold drawing. Carbon steel tubes have an important position in China’s seamless steel tube industry. The key materials are mainly q235, 20#, 35#, 45#, and 16mn. The most important product implementation standards include…
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…
