Stainless Steel Coils Tube Specification:
The seamless stainless steel coil is cold-drawn from stainless steel tube billet, rather than welded with plate. It is first cold-rolled and then cold-drawn and coiled.
The Welded stainless steel coil: The stainless steel strip is welded and then the wall is reduced, and the wall is reduced from thick to thin. This process can make the wall thickness uniform and smooth, and the wall-reduced and stretched tube wall forms the effect of no weld. According to the naked eye, it is a seamless pipe, but its process decision is a welded pipe.
ASTM A213: Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.
ASTM A249: Welded Austenitic Steel Boiler, Superheater, Heat Exchanger, and Coils Tubes.
ASTM A269: Seamless and Welded Austenitic Stainless Steel Tube for General Service.
JIS G 3643: Stainless steel boiler and heat exchanger tubes.
