High-strength Carbon Steel Tubes For Heat Transfer Applications
Astm a214 erw boiler tubes offer high-strength, corrosion-resistant solutions for heat exchangers, condensers, and boiler systems.
ASTM A214 ERW Boiler Tube is a minimum-wall-thickness, electric-resistance-welded (ERW) carbon steel tube designed for heat exchangers, condensers, and boiler systems. Compliant with ASTM A214/ASME SA214 standards, these tubes offer a tensile strength of at least 47 ksi (325 MPa) and yield strength of 26 ksi (180 MPa), making them ideal for high-temperature and pressure applications in power plants, petrochemical processing, and HVAC systems.
ASTM A214 Carbon Steel Pipe are heat treated at a temperature of 1200℉(650℃) or higher and following by cooling in air or in a cooling chamber of a controlled atmosphere furnace.
Manufactured through electric resistance welding, ASTM A214 ERW Boiler Tubes undergo heat treatment at 1650°F (900°C) or higher, followed by air cooling or controlled furnace cooling to ensure weld integrity and eliminate untempered martensite. Available in sizes up to 3 inches (76.2 mm) in outside diameter, with wall thicknesses from 0.8 mm to 12.7 mm, these tubes can be customized for length (3–12 meters) and surface finishes like bright annealed, polished, or coated for enhanced corrosion resistance.
Rigorous testing, including flattening, flange, reverse flattening, hardness (≤72 HRB), and hydrostatic or nondestructive electric tests, ensures compliance with ASTM A214 standards. These tubes are designed for applications requiring efficient heat transfer, such as in boiler flues, superheater flues, and safe ends, with excellent resistance to thermal stress and corrosion in demanding environments.
Compared to seamless tubes like ASTM A179, ASTM A214 ERW Boiler Tubes offer cost-effective solutions with comparable performance for low to medium-pressure systems. Their carbon steel composition ensures durability and weldability, making them suitable for bending and forming in complex piping systems.
ASTM A214 ERW Boiler Tubes address challenges like pipeline wear, thermal stress, and corrosion, providing reliable, high-performance solutions for heat transfer and boiler applications in industrial settings.
