seamless mild steel tube

Seamless mild steel tube description

The seamless mild steel tube is made of a steel ingot or a solid tube blank through perforation, and then hot-rolled, cold-rolled or cold-drawn.
Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (dial) seamless steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Stainless steel thin-walled steel pipes, special-shaped steel pipes.

The carbon content of seamless mild steel tube is less than 0.25%. It is often used in structures, fluid transportation, low and medium pressure boilers, high pressure boilers, fertilizer equipment, oil cracking, geological drilling, diamond core drilling, oil drilling, ships, and automobile half shafts Casing, diesel engine, etc.
