What is the difference between SSAW spiral welded carbon steel pipe and LSAW carbon steel pipe?

SSAW (Spiral Submerged Arc Welding) and LSAW (Longitudinal Submerged Arc Welding) are two types of carbon steel pipe welding techniques. The main differences between SSAW spiral welded carbon steel pipe and LSAW carbon steel pipe are as follows: Manufacturing process: The SSAW pipe is produced by spiralizing a steel coil into a pipe shape and welding the edges together using a submerged arc welding process, while the LSAW pipe is produced by bending and shaping a steel plate into a pipe shape and then welding the edges together using a submerged arc welding process. Pipe diameter and wall thickness: SSAW pipes can be manufactured in larger diameters and with thicker walls than LSAW pipes. This makes them suitable for use in high-pressure applications. Quality control: The manufacturing process of SSAW pipes allows for more precise control over the welding process, resulting in a higher-quality weld compared to LSAW pipes. Cost: LSAW pipes are generally less expensive to manufacture and are preferred for lower pressure applications. However, for larger diameter and higher pressure applications, SSAW pipes may be more cost-effective due to their ability to be manufactured in larger diameters and thicker walls. In summary, both SSAW and LSAW carbon steel pipes have their advantages and disadvantages depending on the application requirements. SSAW pipes are suitable for large diameter and high-pressure applications, while LSAW pipes are preferred for lower pressure applications and when cost is a primary consideration.
