- Straight seam welded pipe has the advantages of high strength, good sealing and low cost, and is widely used in many fields
Straight Seam Steel Pipe
Straight seam steel pipe is a steel pipe with the weld parallel to the longitudinal direction of the steel pipe. The following is some introduction to straight seam steel pipe:
Use:
Straight seam steel pipe is mainly used to transport general low-pressure fluids, such as water, gas, air, oil and heating steam.
Straight Seam Welded Steel Pipe
It can be used for low-pressure water pipes, such as water supply and drainage pipes, heating pipes, low-pressure process pipes, low-pressure fire protection pipes, etc.
Can be made into scaffolding pipes and wire and cable protection pipes.
Can be used as structural support pipes, such as steel structure support pipes, concrete formwork support pipes, grid steel structure pipes, small temporary building columns, etc.
Used as decorative pipes, such as artistic modeling pipes for decorative projects, stair railings, guardrails, etc.
It can also be used as casing or reserved hole pipes
Production process:
According to the production process, it can be divided into two common types: high-frequency straight seam steel pipes and submerged arc welding straight seam steel pipes.
During the production process, for example, the production line for manufacturing large-diameter submerged arc welded straight seam steel pipes will have steps such as full-plate ultrasonic testing and edge milling (using a milling machine to process the steel plate to the required plate width and make the edges of the two edge plates parallel to form a groove).
Specification features:
The specifications of nominal diameter steel pipes are usually in inches, which is an approximate value of the inner diameter.
Steel pipes are divided into threaded and non-threaded types according to the form of the pipe ends.
The specifications of welded pipes are expressed in nominal diameters (mm or inches), which are different from the actual diameters. Welded pipes are divided into ordinary steel pipes and thickened steel pipes according to the specified wall thickness.
The production process of straight seam welded pipes is simple, with high production efficiency, low cost, and rapid development. At the same time, straight seam steel pipes for different purposes may differ in material, specifications, etc.
