Longitudinally Submerged Arc Welded (LSAW) steel pipes are highly regarded across various industries due to their exceptional performance and broad range of applications. These pipes typically have a diameter range from 406mm to 1600mm, and in special cases, can even exceed these dimensions. The wall thickness to diameter ratio of these pipes is approximately between 0.06 to 0.08, with modern foreign technologies capable of producing pipes with a wall thickness of up to 100mm.
The production of LSAW pipes involves several methods, primarily differentiated by the way the steel pipe is formed, while the subsequent processes after forming are largely the same. The welding method depends on the distribution of the steel and takes two basic forms: straight seam and spiral seam. Correspondingly, there are production methods for both straight seam welded pipes and spiral seam pipes. The most widely used method for these pipes is Submerged Arc Welding (SAW), which is recognized for its high quality, high productivity, and mature and stable technology.
The application scope of straight seam pipes is extensive and includes, but is not limited to, the following areas:
- Air, land, and sea transportation sectors for structural components of various transport vehicles.
- Water and oil trunk pipelines for the long-distance transmission of fluids.
- Transportation of chemicals and chemical products, particularly stainless steel pipes for the conveyance of chemical substances.
- Marine industrial structures, utilized in the construction of offshore platforms and structures.
- Boiler manufacturing and structural pipes for special purposes, employed in high-pressure and high-temperature industrial applications.
LSAW pipes are favored for their excellent resistance to high pressure and low-temperature corrosion. They are especially crucial in the oil and gas industry for efficiently transporting hydrocarbons over long distances. Additionally, LSAW pipes find extensive use in marine engineering, water conservancy projects, power projects, and construction projects, making them an ideal choice due to their high strength, toughness, uniformity, and density.
In summary, LSAW steel pipes play an indispensable role in modern industry due to their superior physical properties and extensive application range.
