Straight seam welded pipes are known for their simple production process, high efficiency, low cost, and rapid development. Spiral welded pipes, however, generally offer greater strength than straight seam pipes. They allow for the production of larger diameter pipes from narrow blanks and can accommodate different diameters using the same width blank. However, the weld length of spiral pipes is 30-100% longer than that of straight pipes of the same length, and production speed is slower.
Straight seam steel pipes are a type of welded pipe, further categorized by production method into high-frequency and submerged arc welded types. Submerged arc welded pipes are divided into UOE, RBE, and JCOE types based on their forming processes. The production of submerged arc welded straight seam pipes involves multiple steps, such as edge inspection, milling, pre-bending, and final X-ray and magnetic powder inspections. These pipes may also undergo coating or anti-corrosion treatments based on customer specifications.
In addition to direct use, straight seam steel pipes can be processed for construction applications through forging, extrusion, rolling, and drawing methods. Forging involves applying pressure to shape the steel, while extrusion is primarily used for non-ferrous metals. Rolling and drawing processes alter the cross-section and length of the pipe.
Applications of straight seam steel pipes include:
- Water supply engineering, petrochemical, chemical, and power industries, as well as agricultural irrigation and urban construction.
- Liquid transportation, such as water supply and drainage.
- Gas transportation, including gas, steam, and liquefied petroleum gas.
- Structural uses in piling pipes, bridges, piers, roads, and building structures.
