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 MoreSeamless pipe has better pressure capacity, strength is higher than ERW welded pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance. Seamless pipe vs welded steel pipe: 1. Appearance difference Seamless steel pipe used steel billet…
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…
