This acronym means Helical Submerged Arc Welded pipes. They are also know as Spiral Submerged Arc Welded pipes. These specification of pipes are assembled via welding. They are mainly deployed for the transportation of oil and gas in some cases, water.
Hope this helps.

Helically submerged arc welded (HSAW) pipe is a type of steel pipe produced using a welding process where the steel strip is formed into a pipe shape and then welded along a helical seam. The submerged arc welding technique involves feeding a granular flux over the weld area, which protects the molten weld pool from contamination and improves the quality of the weld. HSAW pipes are commonly used in various applications, including oil and gas transportation, water supply, and structural applications, due to their strength and durability. Their manufacturing process allows for the production of large-diameter pipes at high speeds.
