Boiler Tubes — Seamless & ERW | ASTM / IBR / BS 3059 Certified
Amardeep Steel has established itself as a trusted manufacturer and supplier of boiler tubes in India - one that is trusted by power plants, refineries, and processors of industries in 100+ countries. We manufacture both seamless and ERW boiler tubes to international standards including ASTM A179, A192, A210, A213, BS 3059, and DIN 2391, and all our tubes carry full IBR (Indian Boiler Regulations) certification.
Our range covers everything from standard carbon steel grades for conventional boiler applications to high-chromium alloy grades like T91 and T92 built for supercritical service conditions. Sizes run from ½" to 6" OD, with custom dimensions available when standard sizes don't fit your requirement. Every tube that leaves our facility goes through strict quality checks starting from raw material inspection right through to hydrostatic testing — so you receive material that genuinely meets your mechanical and chemical specifications, not just one that's stamped to say it does.

Frequently Asked Questions — Boiler Tubes
What material is used for boiler tubes?
Boiler tubes are primarily made from carbon steel (ASTM A179, A192, A210) and alloy steel (ASTM A213 grades T2, T11, T22, T91). The material choice depends on the operating temperature, pressure class, and the medium being handled. Carbon steel grades are used for low to medium pressure applications, while alloy steel grades like T91 are engineered for high-temperature supercritical boilers. Amardeep Steel stocks all major grades and can advise on the correct selection for your application.
What is the difference between seamless and ERW boiler tubes?
Seamless boiler tubes are manufactured from a solid billet without any weld seam, making them ideal for high-pressure and high-temperature applications such as superheaters and reheaters. ERW (Electric Resistance Welded) boiler tubes are formed from a steel strip and welded longitudinally; they are more economical and are suitable for lower-pressure boiler systems. Both types are supplied by Amardeep Steel and comply with IBR regulations and relevant ASTM / BS standards.
What is the price of boiler tubes in India?
The price of boiler tubes in India typically ranges from ₹70 to ₹100 per kg for standard carbon steel grades in 1.5" to 2" OD sizes. Prices vary based on the material grade (carbon vs. alloy), outer diameter, wall thickness, and order quantity. Alloy grades like T22 and T91 carry a higher price reflecting raw material costs. Contact Amardeep Steel for a current, quantity-specific price list with mill test reports included.
What is ASTM A213 for boiler tubes?
ASTM A213 is the standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. Key grades include T2, T11, T12, T22, T91, and T92, each engineered for progressively higher operating temperatures. T91 grade, for example, is widely used in supercritical and ultra-supercritical power plants where operating temperatures exceed 600°C. All ASTM A213 grades are available from Amardeep Steel with full material certification.
What is the ASME code for boiler tubes?
The primary ASME code governing boiler tubes is ASME Section I (Rules for Construction of Power Boilers) and Section VIII (Pressure Vessels). Material specifications are defined under ASME SA standards, which are identical to ASTM standards — for example, ASME SA192 corresponds to ASTM A192, and ASME SA213 corresponds to ASTM A213 for alloy steel boiler and superheater tubes. Amardeep Steel can supply material with dual ASTM/ASME certification as required.
