Carbon Steel Boiler Tubes Manufacturer and Supplier

Carbon steel boiler tubes are industrial conduits composed of iron and carbon, containing up to 1.2% manganese and 0.4% silicon. These critical components uphold international standards like ASTM A192, A210, and A178, securing the safety and performance required for intense thermal power applications.

ASTM A192 tubes feature a composition of 0.06 to 0.18% Carbon, providing a tensile strength of 325 MPa and 180 MPa yield. Carbon steel is the most popular choice worldwide for keeping high-temperature boiler pressure systems efficient because it conducts heat well and performs reliably at temperatures up to 1000°F (538°C).

Sachiya Steel International is a trusted carbon steel boiler tubes manufacturer, supplier, stockist, and exporter based in Mumbai, India. We hold ISO 9001, 14001 and 45001 certifications. With an experience of more than 20 years and a ready inventory of 1,500 to 2,000 metric tons covering seamless and ERW boiler tubing. IBR-approved tubes ship with mill test certificates.

We supply carbon steel boiler tubes globally, offering diameters from 10mm to 200mm and walls up to 20mm. Our 12-meter lengths support industrial steam systems and heat exchangers everywhere.

Carbon Steel Boiler Tube Industrial Applications

CS boiler tubes serve fire-tube boilers, water-tube boilers, superheaters, economisers, and heat exchangers in 3 key sectors.

Power Generation

Thermal power plants use carbon steel boiler tubes in water-wall panels and superheater systems for efficient heat transfer.

Oil and Gas and Petrochemical

Refineries and petrochemical plants rely on carbon steel boiler tubes in waste heat recovery boilers and process systems.

Industrial Steam Systems

Food processing, textile, and paper industries use boiler tubes for efficient saturated steam generation.

Carbon Steel Boiler Tube Grades

Boiler tube material grades include ASTM A192 (single grade), ASTM A210 (Grades A-1, C), and ASTM A178 (Grades A, C, D).

ASTM A192 / ASME SA-192 Grade A:

ASTM A192 (UNS K01200) is a seamless low-carbon steel specification for high-pressure boiler service. It operates up to 1000°F (538°C), though graphitization risk increases significantly when temperatures exceed 800°F (427°C).

ASTM A210 / ASME SA-210 Grades:

A210 covers seamless medium-carbon tubes where higher strength is required.

Grade A-1:

Offers superior tensile and yield strength compared to A192, making it ideal for high-performance superheater tube applications.

Grade C:

Provides maximum structural strength for critical, high-temperature superheater service in demanding industrial boiler environments.

ASTM A210 and ASTM A178 Grades

ASTM A178 specifies ERW boiler tubes across three distinct grades, categorised by their carbon content and mechanical performance.

Grade A:

Grade A is a low-carbon ERW tube designed specifically for fire tubes and boiler flues in low-pressure systems.

Grade C:

SA-178 Grade C delivers a robust 415 MPa tensile strength, supporting higher-pressure ERW service across various power plant components.

Grade D:

Grade D uses carbon-manganese alloying to achieve a high 485 MPa tensile strength for the most demanding pressure applications.
