Original Factory Oval Steel Bar - 321 Stainless steel seamless round pipe – Join

Chemical Component

Outer Diameter: 6mm~720mm ; 1/8’’~36’’

Wall thickness: 0.89mm~60mm

Tolerance:+/-0.05~ +/-0.02

Technology:

• Drawing: Drawing the rolled blank through the die hole into a section to reduce the increase in length
• Rolling: the blank is passed through the gap of a pair of rotating rollers. Due to the compression of the rollers, the material section is reduced and the length is increased. This is a common way to produce steel tubes
• Forging: To change the blank into the desired shape and size by using the reciprocating impact force of the hammer or the pressure of the press
• Extrusion: The blank is placed in a closed extrusion container with pressure applied at one end to extrude the blank from the specified die hole to obtain different shapes and sizes

Features: Because of its excellent corrosion resistance, 321 stainless steel is often used in harsh working conditions or in the manufacture of tableware and medical appliances.Steel pipe with hollow section is widely used for conveying fluid, such as conveying oil, natural gas, gas, water and some solid materials
