Welded pipes can be classified in many ways according to different standards. Here are several common classification methods and their detailed descriptions:
Material classification:
Steel welded pipe: Made of ordinary steel, widely used in general industrial pipelines.
Stainless steel welded pipe: Has better corrosion resistance and is suitable for chemical, food and other industries.
Copper welded pipe: Used for fluid transmission in special environments.
Process classification:
High-frequency welded pipe: Welded with high-frequency current.
Electric welded pipe: Welded by arc welding.
Spiral welded pipe: Steel strip is rolled into a spiral shape and then welded.
Straight seam welded pipe: The weld is spread along the longitudinal direction of the steel pipe, including straight seam electric resistance welded pipe (ERW) and straight seam submerged arc welded pipe (LSAW)
Wall thickness classification:
Thin-walled steel pipe: Thin wall thickness, suitable for light load applications.
Thick-walled steel pipe: thicker wall, suitable for heavy load and high pressure environment
Application classification:
Civil pipe: used for decoration, construction, structure, etc., such as round pipe, rectangular pipe, flower pipe.
Industrial pipe: used for industrial piping, fluid transportation, boiler heat exchange, food hygiene, etc., such as petrochemical, papermaking, nuclear energy, food, beverage, medicine and other industries
