This week we have sent 20 containers seamless carbon steel pipe GB3087 20# to domestic project of Supermarket.
you can find different pipe from different mills. Don't just see price because maybe you will have more troube
after receiving goods.
It is mainly used to make high-quality carbon structural steel, low pressure medium pressure boiler pipe, super heated steam carbon steel pipe
Grade of high-quality carbon structural steel: 10#,20#
