The production process of seamless steel pipe
2023-10-11
① Main production process of hot rolled seamless steel pipe (△ main inspection process) : Preparation and inspection of tube blank △ heating of tube blank → perforation → Rolling pipe → reheating of steel pipe → fixing (reducing) diameter → heat treatment △ straightening of finished pipe → finishing → inspection △ (non-destructive, physical and chemical, table inspection) → storage
The steel type of thick steel plate is roughly the same as that of thin steel plate.
2023-03-06
Steel tubes made of a single piece of metal with no seams on the surface are called seamless steel tubes. According to the production method, seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe
Performance index of steel pipe
2022-10-30
The mechanical property of steel is an important index to guarantee the final serviceability (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to different use requirements, the tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as user requirements of high, low temperature performance.
Corrosion resistance of welded steel tubes
2022-07-13
In the production of T-welded steel pipe, the wrong edge often occurs, and there are many influencing factors. In production practice, steel pipe is often degraded by the wrong edge. Therefore, it is necessary to analyze the causes of spiral steel pipe misalignment and its preventive measures.

Square pipe is a kind of hollow square section of light thin-wall steel pipe, also known as steel cooling bent profile. It is Q235 hot rolled or cold rolled strip steel or coil as the base material after cold bending processing and then high frequency welding made of square section shape size of the section steel. In addition to the thickening of the wall, the corner size and the flatness of the edge of the hot rolled extra-thick wall square pipe reach or even exceed the level of the resistance welding cold-formed square pipe.
