Industrial 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…

Read MoreThe galvanizing method of seamless pipe (SMLS) shall be hot-dip galvanizing. Size, shape, surface, mechanical properties and process performance inspection should be carried out before galvanizing. Surface quality requirements of galvanized layer: The galvanized layer on the inner and outer surfaces of the seamless steel pipe should be complete, no black spots and air bubbles without zinc plating are…
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 MoreFire-fighting pipeline refers to the pipeline material used for fire-fighting, connecting fire-fighting equipment and equipment, and transporting fire-fighting water, gas or other media. Due to special requirements, the thickness and material of fire-fighting pipes have special requirements, and red paint is sprayed to transport fire-fighting water. Since the fire pipeline is often in a static state, the requirements for…
