The installation method of stainless steel pipes is the same as that of ordinary carbon steel, and some processes have the following process requirements.1 Stainless steel materials should not be in direct contact with other metals when being lifted and should be padded with non-metallic materials s

Welded steel pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW), and straight seam submerged arc welding (LSAW). The welded pipes produced by these three processes have their positioning and advantages in the application field due to

1. Shoddy steel product is prone to folding. Folding is a variety of fold lines formed on the surface of the steel, and this defect often runs through the longitudinal direction of the entire product. The reason for the folding is that the counterfeit and inferior manufacturers pursue high efficienc

1. Cleaning method: When cleaning the surface of the stainless steel pipe, care must be taken not to scratch the surface. Avoid using bleaching ingredients and abrasive washing liquid, steel wire balls, grinding tools, etc. To remove the washing liquid, rinse with clean water at the end of the washi

Seamless steel pipes are widely used. 1. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for conveying fluids. 2. There are three ty

1. Straight seam high-frequency welded steel pipe: Straight seam high-frequency welded steel pipe is a welded steel pipe that is continuously produced on the production line using steel strip (coil) as the raw material and high-frequency welding process. The material strength is generally below 450M

The high-frequency induction coil of the straight seam steel pipe should be as close as possible to the position of the extrusion roller. The internal stress of the steel pipe is small and evenly distributed, which can effectively prevent stress corrosion cracking, high dimensional accuracy, and fac

The fire-fighting pipeline includes two systems: the fire hydrant system and the water sprinkler system.Stainless steel fire-fighting piping system is a kind of fixed fire-fighting facility widely used in China. Nowadays, 304 stainless steel pipes are used in fire water supply pipes in sprinkler sys

Production temperature of straight seam steel pipe: In the process of producing straight seam steel pipe, the temperature must be strictly controlled, to ensure the reliability of welding. If the temperature is too low, it may cause the welding position to fail to reach the temperature required for

The spiral seam submerged arc welded steel pipe is drilled in rotation and begins to enter the soft formation. Under the action of the tritone, the drill bit first produces elastic shear deformation of the formation and then is removed under the pressure of the tritone. In the simulated environment,
