Structural steel pipe

Description: Steel structural steel pipes refer to steel pipes that are formed and welded automatically by longitudinal cutting or strip rolling after passing the re inspection using rolled plates. While the computer controls the optimal fusion temperature, the inner and outer burrs of the steel pipes are removed. The steel pipes that pass non-destructive testing are heated to 910 ℃ -950 ℃ in an oxidizing atmosphere and taken out of the furnace. After descaling, they are rolled multiple times by a tension reducing machine to achieve uniform metallographic structure, grain state, geometric dimensions, and mechanical properties in all parts of the steel pipes. The product complies with APISPEC5L, APISPEC5CT, and EN10217 standards.
