The welding technology of S690QL1 steel tubing weight

Is there a difference between seamless steel pipe and ordinary steel pipe? The general requirements of S690QL1 steel tubing weight ordinary steel pipe are not so high, which are used in ordinary buildings or structures. According to the different materials and standards, seamless steel pipe will have different application environment. For example, seamless steel pipe for boiler requires pressure value. Seamless steel pipe for petroleum cracking also has its own corresponding national standard. Seamless steel pipe can be divided into fluid pipe, gas cylinder pipe, boiler pipe, oil pipe, automobile steel pipe, ship pipe, structural pipe, etc.

The cold working performance of S690QL1 steel tubing weight and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of S690QL1 steel tubing weight and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

Punchability refers to the performance of metal without cracks and other defects after stamping deformation. Many steel products are manufactured through a stamping process. In order to ensure the quality of the products and the smooth progress of the process, the S690QL1 steel tubing weight, steel plates and strips used for stamping must have qualified stamping performance.
