ASTM A249 TP321 Heat Exchanger Tube supplier
ASTM A249 TP321 welded boiler tubes cover nominal wall thickness welded tubes and heavily cold-worked welded tubes made of austenitic stainless steel. ASTM A249 TP321 welded austenitic stainless steel tubes are suitable for applications such as boilers, superheaters, heat exchangers, or condensers.
The ASTM A249 TP321 bright annealed welded tubes we offer contain titanium, which enhances the stability of the titanium alloy and provides excellent resistance to intergranular corrosion. This characteristic is crucial for maintaining the integrity of the tubing in high-temperature and high-pressure environments. The bright annealing surface treatment is achieved by heating the metal in a controlled atmosphere, which softens the material, making it easier to process, and resulting in a clean, smooth surface. ASTM A249 TP321 bright annealed tubes are ideal for applications such as heat exchangers, boilers, and superheaters where corrosion resistance and a clean surface are essential.
The dimensions and thicknesses of ASTM A249 TP321 welded boiler tubes typically conform to this specification, with an inner diameter ranging from 1/8 inch [3.2 mm] to an outer diameter of 12 inches [304.8 mm], and a wall thickness ranging from 0.015 to 0.320 inches [0.4 to 8.1 mm] (inclusive).
