Boiler Materials by Component

A water-tube boiler is made of several pressure parts, each running at a different metal temperature. Cooler parts use carbon steel; parts that run hotter, such as superheaters and their headers, need chrome-moly alloy steel. The table below shows the usual product form and material for each component.

Boiler Component	Product Form	Usual Materials
Water walls (membrane panels)	Seamless tube	SA210 A1, SA192
Boiler bank / generating tubes	Seamless tube	SA192, SA210 A1
Economiser coils	Seamless tube (plain or finned)	SA210 A1, SA192
Low-temperature superheater coils	Seamless tube	SA210 C, SA213 T11
High-temperature superheater and reheater coils	Seamless tube	SA213 T22, T91; TP304H / TP347H stainless
Economiser and water wall headers, downcomers	Seamless pipe	SA106 Gr B / C
Superheater headers, main steam line	Seamless pipe	SA335 P11, P22, P91
Feedwater and drum nozzle piping	Seamless pipe	SA106 Gr B
Bends, tees, reducers, end caps	Butt-weld fittings	SA234 WPB; WP11, WP22, WP91 for alloy lines
Valve and line connections	Flanges	SA105; SA182 F11, F22, F91 for alloy lines
Fire-tube / smoke tubes	ERW or seamless tube	SA178 A, SA192, BS 3059 Part 1 ERW 320
Air preheater	ERW tube	SA214, Corten A423 Gr 1, SA178 A

Typical selections only. The boiler designer chooses the grade from metal temperature, pressure and the design code (ASME Section I or IBR). Drums are made from boiler-quality plate by the boiler maker.

Boiler Industry Materials: FAQs

Which tubes are used for boiler water walls?

Water walls are usually made from seamless carbon steel tubes to ASME SA210 Grade A1 or SA192, joined by fin bars or strips into gas-tight membrane panels. SA210 A1 is stronger, so it allows a thinner wall at the same pressure; SA192 is a softer low-carbon grade often used in lower-pressure boilers.

What material is used for superheater tubes?

Low-temperature superheater stages often use SA210 Grade C or SA213 T11. Hotter stages and reheaters use chrome-moly alloy tubes such as SA213 T22 and T91, which keep their strength and resist oxidation at high metal temperatures. The hottest sections may use stainless steel TP304H or TP347H.

Which tubes are used for economiser coils?

Economisers run at feedwater temperature, so they normally use carbon steel seamless tubes to SA210 A1 or SA192. The tubes may be plain or finned; finning and coil bending are done by the boiler maker or fabricator.

What pipe is used for boiler headers?

Headers that carry water or saturated steam are usually seamless carbon steel pipe to ASME SA106 Grade B or C. Superheater outlet headers and main steam lines run hotter and use alloy steel pipe to SA335 P11, P22 or P91.

Do you supply fabricated coils and water wall panels?

We supply the tubes and pipes used to build boiler components, cut to length to your drawing, along with matching fittings and flanges. Coil bending, finning and membrane panel welding are normally done by the boiler maker or fabricator.

Can you supply boiler materials with IBR certificates?

Yes. For boilers registered in India we supply pipes with IBR Form III-A and tubes with IBR Form III-B on request, after inspection by an IBR-recognised inspecting authority. Mention the IBR requirement in your enquiry, as it affects lead time.

Export Destinations

We export boiler pipes and tubes to the Middle East (UAE, Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, Iraq), Africa (Nigeria, Egypt, South Africa, Kenya, Ghana, Tanzania), Asia (Bangladesh, Sri Lanka, Nepal, Indonesia, Malaysia, Thailand, Vietnam, Philippines) and other markets on request.
