Insulation spiral steel pipe is to insulate spiral steel pipe (SSAW pipe). The most important method of heat preservation is polyurethane heat preservation spiral pipe. After pre-treatment such as rust removal, the steel pipe is covered with a layer of polyethylene or steel.

Spiral steel pipe (SSAW pipe) is a welded pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel into the welded pipe unit, and after rolling by multiple rollers, the strip steel is gradually rolled up to form a circular tube blank with an opening gap.

The vacuum heat treatment of steel pipes (such as seamless pipes and welded pipes) is a new heat treatment technology that combines vacuum technology and heat treatment technology. The vacuum environment in which vacuum heat treatment is located refers to the atmosphere environment below one atmospheric pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum.

Hydraulic steel pipes are basically divided into fluid pipes and oil steel tubes used in hydraulic systems, also known as honing pipes, and cold drawn or cold rolled seamless steel pipes also include hydraulic steel pipes.

Sand blasting, also known as sand blasting, is a surface treatment method that uses high-speed jets of sand to polish the metal surface to remove rust, scale and dirt, while improving the roughness of the metal surface. Why is steel pipe (such as seamless pipe or welded pipe) required to be sandblasted before anticorrosion?

Water quenching is a very common quenching agent for heat treatment of steel pipes (seamless pipes or welded pipes), which can rapidly reduce the temperature during high-temperature treatment to achieve cooling of steel pipe metal.
