api 5l standard seamless pipe for oil and gas




 Definition:a heated solid billet by piercing,rolling,reducing cold rolling is rolled,rolled into seamless hollow steel tube.

Summary:hot rolling is relative to the cold rolling,below the recrystallization temperature but hot rolling is rolled in above the recrystallization temperature of.
Advantage:it can destroy the ingot casing,refinement steel grain,and eliminating the defect in microstructure,thus making steel dense tissue,with improved mechanical properties.This improvement mainly reflected along the rolling direction,so that steel is no longer a certain extent,isotropic,bubbles,cracks and loose,can also be welded under high temperature and pressure.
