TP304L Stainless Steel Seamless Heat Exchanger Tube 33.7mm OD × 1.5mm Wall ASTM A213-2018
ASTM A213-2018 TP304L stainless steel seamless tube measuring 33.7mm OD × 1.5mm wall thickness × 4000mm length, specifically engineered for heat exchanger applications. These tubes offer superior performance in demanding industrial environments.
In damp industrial or coastal European atmospheres, TP304L stainless steel demonstrates enhanced corrosion resistance compared to standard TP304/304L and ferritic grades. While offering limited pitting resistance in low-temperature seawater, these tubes maintain excellent short- and long-term properties at elevated temperatures.
- ASTM A213/SA213: Seamless ferritic and austenitic alloy-steel boiler, superheater and heat exchanger tubes
- ASTM A249/A249M: Welded austenitic steel boiler, superheater, heat-exchanger, and condenser tubes
- Additional standards: DIN 17456, DIN 17458, EN10216-5, GOST 9940-81, GOST 9941-81, JIS-G3463
