AISI 304 ASME SA249 63.5 X 2.11MM Welded Bright Annealed Stainless Steel Tubes, Inside Bead Removed.

ASME SA 249 standard is for welded stainless steel tubes, the tubes are installed for heat changer, boiler and condenser in heating or cooling deliver system. The tube is made starting from stainless steel strip or coil, welding both edges, forming the shape, rolls inside and outside surface, that will be shape tubes, then heat treatment and cold working process should be made conforming to this standard.

ASME SA 249 stainless steel heat exchanger, boiler and condenser tubes have various sizes with various grades, outside diameter, wall thickness, as well as length is main size requirement. custom sizes we offered for welded tubes are as below.

Outside diameter: range from 6 to 304.8 mm, custom sizes have 16, 19.05, 25.4, 31.8, 38.1, 44.45, 50.8, 76.2, 101.6 mm

Wall thickness: average thickness and minimum thickness are available, there are 0.71, 0.89, 1.0, 1.25, 1.65, 2.11, 2.77 mm.

Tolerance of outside diameter and thickness should conform to ASME SA 249 specification and ASTM A1016/M, welded tubes require precise tolerance for the specific use.
