Quality Inspection for Super Duplex Bar - 304 304L Stainless steel seamless round pipe – TISCO

Chemical Component

Wall thickness: 0.89mm~60mmOuter Diameter: 6mm~720mm ; 1/8’’~36’’

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:304 stainless steel tube has good intercrystal corrosion resistance, excellent corrosion performance and cold working, stamping performance, can be used as heat resistant stainless steel.At the same time, the mechanical properties of the steel are still good at -180℃.Under the condition of solid solution, the steel has good plasticity, toughness and cold working property.Good corrosion resistance in oxidizing acid and atmosphere, water and other media, therefore, the production and use of 304 stainless steel is the largest, the most widely used type of steel.

Application:

• Oil&Gas;
•  Food& Drug;
• Medical;
• Transportation;
• Construction..

 Pipes are round, cylindrical shapes that are hollow. They are used primarily for the transference of either fluids or gas. All pipes are measured by their Nominal Inside Diameter and their Wall Thickness, which is based on a Schedule number. The higher the schedule number, the thicker the wall.
