Wheatland Tube’s SureThread standard steel pipe is hot-formed, which means the entire piece is heated during tube formation, not just the edges. The pipe is heated and then slowly cooled in order to toughen and reduce brittleness — a process known as annealing.
As the coiled steel reaches 2,450 °F, rollers bend the steel into a cylindrical shape and the pressure and heat fuse the edges together. There are no flash forms in this process, allowing for a continuous weld. The pipe is available in 1/4”- 4” NPS, is hot-dip galvanized to ASTM A53 requirements and comes in 350 combinations of finish and end treatments.
