Wave inspection technology for straight seam steel pipe welds is a relatively new testing process that plays a significant role in improving the stability of straight seam steel pipes. This article will provide a detailed introduction to the specific applications and common problems of wave inspecti

First, what is steel bending pipe?Steel bending pipe is made by bending using a set of bending dies. It is used in most types of machinery and equipment, mainly for transporting oil, gas, and liquids. It plays a particularly important role in aircraft and their engines.Second, can steel bending pipe

API standards stipulate that the inner and outer surfaces of inlet and outlet oil casings must be free of folds, separations, cracks, and scratches. These defects must be thoroughly removed to a depth not less than 12.5% of the nominal oil casing wall thickness. Oil casings must undergo full-coverag

First, what are the production methods of boiler steel pipes?Boiler steel pipes are a type of seamless steel pipe. The manufacturing method is the same as that of seamless steel pipes, but there are strict requirements on the steel grades used. Based on the operating temperature, they are divided in

1. What is the standard for GB/T3087-2022 low and medium pressure boiler steel pipes?GB/T3087-2022 is a national standard for seamless steel pipes used in low and medium pressure boilers, replacing the old version GB3087-2008. This standard specifies the dimensions, shape, weight, technical requirem

First, what are the optimization goals for precision steel pipe fittings?(A) Performance Indicators: While ensuring dimensional accuracy (tolerance ≤ 0.1%), increase the tensile strength of carbon steel and alloy steel pipes by 20%-30%, optimize impact energy by more than 15%, control hardness unifo

First, what are the basic properties of Q355B seamless square and rectangular steel pipes?(1) Material composition: Q355B is a low-alloy high-strength structural steel. Its chemical composition mainly includes elements such as carbon, silicon, manganese, phosphorus, and sulfur. The carbon content ge

How is the root pass welding of stainless steel pipes performed? The welding of stainless steel pipes typically consists of several parts: root pass welding, filler weld, and cover pass welding. The root pass welding is the most critical step in stainless steel pipe welding, affecting not only the q

The following is a summary of key information regarding the delivery condition of 12Cr1MoVG high-pressure alloy steel pipe:What is the standard for 12Cr1MoVG high-pressure alloy steel pipe?GB/T 5310-2017 "Seamless Steel Tubes for High-Pressure Boilers": This standard clearly specifies the delivery c

What is the production process of ASTM A333 Gr.6 low-temperature seamless steel pipe?1. Smelting and Continuous Casting: Smelting is carried out in an electric furnace or converter. Refining processes (such as LF refining and VD vacuum degassing) are used to control the purity of the molten steel, r
