ASTM A214 Carbon Steel Tube / ASME SA214 Heat Exchanger Tubes
When industries need reliable, strong, and cost-effective tubing for boilers, heat exchangers, condensers, and pressure applications, ASTM A214 Carbon Steel Tubes (also known as ASME SA214 Tubes) are one of the most trusted choices. These tubes are electric-resistance-welded (ERW) carbon steel tubes designed to work safely under heat and pressure while delivering long service life.
We supply and manufacture ASTM A214 Carbon Steel Tube / ASME SA214 Heat Exchanger Tubes for customers in power plants, refineries, chemical plants, fertilizer units, sugar mills, and many other industries where efficient heat transfer and safe operation matter every day.
As an ASTM A214 Tubes Manufacturer, ASME SA214 Tubes Supplier, and ASTM A214 Tubes Stockist, we focus on three things: consistent quality, practical performance, and dependable supply.
What is ASTM A214 / ASME SA214 Carbon Steel Tube?
ASTM A214 (also known as ASME SA214) is a standard specification for electric-resistance-welded (ERW) carbon steel tubes used mainly in:
- Boilers
- Heat exchangers
- Condensers
- Economizers
- Pressure vessels
These products are commonly called SA214 Electric-Resistance-Welded Carbon Steel Tubes or ASTM A214 Boiler Tubes.
They are made from carbon steel using the ERW (Electric Resistance Welding) process, which ensures:
- Strong and uniform weld seam
- Good dimensional accuracy
- Consistent mechanical properties
- Cost-effective production
Because of this balance of performance and price, ASME SA214 ERW Carbon Steel Tubes are widely used in both new installations and plant maintenance projects.

Why ASTM A214 Tubes Are Widely Used in Industry
From real project experience, customers choose SA214 Carbon Steel Tubes for a few clear reasons:
- Reliable Under Heat and Pressure: These tubes are specially designed for heat exchangers and boiler services, where temperature and pressure are always high.
- Cost-Effective Choice: Compared to seamless tubes, SA214 Welded Carbon Steel Tubes are usually more economical while still meeting standard performance needs.
- Easy to Fabricate and Install: CS A214 Tubes are easy to cut, expand, bend, and weld, which reduces fabrication time and overall project cost.
- Wide Size Availability: As an ASTM A214 ERW Tubes Manufacturer and Supplier, we provide a broad range of diameters, thicknesses, and lengths, including custom sizes.
Manufacturing Process: SA214 Electric-Resistance-Welded Carbon Steel Tube
The ASTM A214 Tubes are manufactured using the ERW (Electric Resistance Welding) process:
- High-quality carbon steel strip is formed into a tubular shape
- The edges are heated using electric resistance
- The heated edges are pressed together to form a strong weld
- The tube is heat treated (when required by the standard)
- Final sizing, straightening, and cutting are carried out
- Each tube is tested and inspected before dispatch
This process ensures uniform wall thickness, a reliable weld seam, and consistent performance in boiler and heat exchanger services.

ASTM A214 vs Other Boiler Tube Grades (Quick Comparison)
- ASTM A214: ERW welded tubes, cost-effective, widely used in heat exchangers and boilers
- ASTM A210 / A192: Seamless boiler and superheater tubes, usually for higher pressure
- ASTM A106 / A53: General-purpose carbon steel pipes and tubes
If your application allows welded tubes, SA214 Carbon Steel Tubes often offer the best balance of performance and cost.
