Spiral welded steel pipes are one of the important materials used in the transportation of media. They are used for the external corrosion protection of steel oil, gas, water, and heating pipelines. What level of durability improvement is best for spiral welded steel pipes? The durability of spiral
First, what is a spiral anti-corrosion steel pipe? In the field of pipeline engineering systems, steel pipe corrosion is a very serious and challenging issue. To solve this problem, a rather remarkable product has emerged on the market—spiral anti-corrosion steel pipe. As the name suggests, spiral a
Thick-walled steel pipes come in a wide variety of steel grades and specifications, with diverse performance requirements. All of these should be differentiated according to changes in user requirements or working conditions. Generally, steel pipe products are classified according to cross-sectional
In the precision machining of steel pipes, cutting is the core process that determines the dimensional accuracy, surface integrity, and service performance of the parts. The cutting process is essentially a dynamic mechanical interaction between the tool and the workpiece, accompanied by a series of
First, the smelting and continuous casting of A333Gr. 6 seamless steel pipes.Smelting is done in an electric furnace or converter. Refining processes (such as LF refining and VD vacuum degassing) control the purity of the molten steel, reducing the content of impurities such as sulfur and phosphorus
The difference between hot and cold working: Hot rolling is hot working, while cold drawing is cold working. The main difference is that hot rolling is performed above the recrystallization temperature, while cold rolling is performed below the recrystallization temperature. Cold rolling sometimes i
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
