Grade ASTM A790 S31803 S32205 S32750 S32760 S32101 Duplex Stainless Steel Pipe
Stainless Steel Seamless Pipe is made from round bar. There are many processes to make round bar to seamless pipe. It is different from welded pipe, seamless pipe has no welding seam across the whole section. Hence, it can bear higher pressure than welded pipe.
It is widely used in the food industry, home appliances and consumer electronics, medical equipment, architectural decoration, hardware tools, automotive industry, petrochemical, water treatment plants, aerospace, etc.
Tubinox is able to make stainless steel seamless pipe as per different standards/specifications, like ASTM A312 / ASME SA312, ASTM A213 / ASME SA213, ASTM A269, ASTM A632 / ASME SA632, JIS G3459, JIS G3448, JIS G3463, EN10216-5, EN ISO1127, DIN 17456, DIN 17458, GOST 9941, etc. We can also make as per custom specification.
