ASTM A672 Pipe is Standard Specification for Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperatures. ASTM A672 LSAW pipelines use a hot rolling process that may be standardized, quenched, disinfected, and is a thermostat and other heat treatment methods compatible. LSAW pipelines are mostly used for land, offshore oil, natural gas, liquid coal, and other long-distance transmission pipelines. ASTM A672 piping material’s chemical composition contains 0.25 carbon max, 0.98 Manganese, 0.64 molybdenum and 0.45 Silicon. Certain mechanical qualities, such as Yield Strength (Mpa) 37 and Tensile Strength (Mpa) 65, are permissible. Contact us if you are looking for an ASTM A672 L65 LSAW pipeline Supplier in India with good quality and affordable pricing.
