Stainless seamless steel pipe is a kind of hollow sec- tion, no joints around the strip steel. It is resistant to air, steam, water and other weak corrosive medium and acid, alkail, salt and other chemical corrosive medium corrosion.
Stainless steel pipe is a kind of hollow long round steel. In addition, when the bending and torsional strength are the same, the weight is light.
Stainless steel pipe has high pres- sure resistance, good toughness and high surface brightness (the surface brightness of the steel pipe deter- mined by the surface grade of the steel plate).
It is widely used in industrial trans- mission pipelines and mechanical structural parts such as petroleum, chemical industry, medical industry, light industry, machinery and instruments.
