ASTM A249 / A249M Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes are designed for high-performance applications in demanding industrial environments.
Suitable for welding austenitic stainless steel pipes used in the manufacture of equipment such as boilers, superheaters, heat exchangers and condensers.
Covers various austenitic stainless steel grades including TP304, TP304L, TP316, TP316L with specific chemical composition requirements for carbon, chromium, nickel, and molybdenum content.
Outer diameter ranges from 1/8 inch (3.2 mm) to 12 inches (304.8 mm), wall thickness from 0.015 inches (0.4 mm) to 0.320 inches (8.1 mm). Custom sizes available upon request.
TP304 offers tensile strength ≥515MPa, yield strength ≥205MPa, and elongation ≥35%, ensuring structural stability and safety under load conditions.
- Standardized welding methods including TIG welding and MIG welding
- Cold processing and heat treatment to optimize weld structure
- Strict raw material selection and quality control throughout production
- Comprehensive raw material analysis and testing
- Real-time monitoring of welding parameters and heat treatment processes
- Finished product inspection including appearance, dimensions, hydrostatic testing
- Non-destructive testing (eddy current, ultrasonic, radiographic)
- Additional tests for special applications (intergranular corrosion, high temperature endurance)
Pipes are delivered in heat-treated, pickled, or surface-treated condition to ensure optimal performance and surface quality for immediate use.
ASTM A249 Welded Stainless Steel Tube is widely used in chemical processing, oil and gas, food processing, pharmaceutical, marine engineering, heat exchanger and boiler manufacturing industries. These tubes perform reliably in high temperature, high pressure, and corrosive environments.
