API 5L, ASTM A53, A178, A500/501, A691, A252, A672, EN 10217 Resistance Welded Pipe is manufactured by continuously coiling metal strips (such as carbon steel or stainless steel) into a tubular shape, utilizing high-frequency current to heat the edges to a plastic state, and then consolidating them through pressure welding. Typical wall thickness ranges from 0.5–20 mm, with diameters up to 24 inches (≈610 mm). Its defining characteristic is a longitudinal weld seam, where welding quality directly determines the pipe's mechanical strength.
