Product Description
Stainless steel pipe is a hollow strip of round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used as furniture and kitchenware.
Stainless steel welded pipe production process: Raw materials - slitting - welding pipe - trimming - polishing - inspection (printing) - packaging - shipping (into the warehouse) (decorative welded pipe). Raw materials--striping--welding pipe--heat treatment--correction--straightening--trimming--pickling--hydraulic pressure test--inspection (printing)-packaging--shipping (warehouse) (Pipe pipe industrial piping pipe).
Stainless steel is a versatile stainless steel that is widely used in the production of equipment and parts that require good comprehensive performance corrosion resistance and molding).In order to maintain the corrosion resistance inherent in stainless steel, stainless steel pipe must contain more than 18% chromium and more than 8% nickel content
