304 304l JIS Seamless Stainless Steel Tube 310s 321 10mm

1.5-22 mm Customized Polished Stainless Tube High Precision Steel Pipe

Product specification:

Stainless steel seamless tube:

Seamless tube is the round tube ingot, through cold rolling, cold drawing or hot extrusion production process. As the seamless tube is made of round tube steel ingot processing, so the precision of the steel tube is low, the wall thickness is not uniform, the brightness of the inner surface is low, the cost of size is increased, and after many times of heating, the inner surface is very easy to have black spots, and it is not easy to remove.

And the steel composition of the production of seamless pipe is only to meet the basic requirements of ASTM, in the welding process will produce a variety of unstable factors, not easy to weld and weld impenetrable. Seamless pipe will also appear metal delamination, residual stress and so on. The price of seamless pipe is higher than that of welded pipe.

Precision stainless steel tube:

The precision stainless steel tube is welded by the steel belt after crimping forming by the unit and the mold, and the welded tube avoids multiple heating processing in the processing process, and the production process is more environmentally friendly and safer. Due to the use of processed stainless steel strip as raw material, so the production of precision tube with high precision, uniform wall thickness, high brightness inside the outer surface, and can be customized according to customer demand.

And the precision tube is formed by precisely grinding the precision machine coil steel after micro-finishing, so its thickness tolerance is smaller. With the same chemical composition, the steel used to make precision tubes has a chemical composition suitable for welding, so its strength is relatively higher. Precision stainless steel welded pipe has the advantages of uniform wall thickness, low residual stress, high welding strength, good consistency and so on.

Not only that, the quality of precision stainless steel tube is better than the comprehensive quality of stainless steel seamless tube, but the market price is only half of the seamless tube.
