We supply large-diameter HSAW steel pipes for bulk water transmission mains, cross-country pipeline projects, irrigation canals, and industrial piping systems. HSAW pipes are manufactured by spirally welding hot-rolled steel coil strips using the submerged arc welding (SAW) process, resulting in strong, precisely dimensioned large-diameter pipes.
