IBR Tubes Supplier in India

IBR Certified Boiler, Superheater & Economiser Tubes

Dinesh Tube India supplies IBR tubes (tubes certified under the Indian Boiler Regulations) from Mumbai to boiler makers, re-tubing contractors, sugar mills, power plants and process industries across India. We supply carbon steel, alloy steel and stainless steel IBR approved tubes, seamless and ERW, cut to length with IBR Form III-B and the mill test certificate.

IBR is a certification, not a tube grade. This page explains what IBR certification of tubes involves and which grades we supply with it. For which grade to use in each part of a boiler, see our boiler tubes guide; for pipes, see IBR pipes (Form III-A).

What Is an IBR Tube?

An IBR tube is a steel tube made, tested and certified to meet the Indian Boiler Regulations, 1950 (IBR), so it can be used in boilers, superheaters, economisers and other pressure parts registered in India. The tube itself is made to a recognised standard, such as ASME SA192, SA210 or SA213, and is then inspected and certified on IBR Form III-B, the Certificate of Manufacture and Test for tubes.

The Boiler Inspector checks this certificate before a boiler is registered, repaired or re-tubed. A tube of the right grade but without Form III-B cannot be used where IBR applies, which is why IBR certification must be stated on the order.

Typical selections only. The boiler designer chooses the grade from metal temperature, pressure and the IBR design rules.

What the IBR Form III-B Certificate Covers

Form III-B is the IBR Certificate of Manufacture and Test for tubes, the counterpart of Form III-A for IBR pipes. It records:

  •   Tube maker, steel maker, steel-making process and heat number
  •   Chemical composition of the heat
  •   Manufacturing process (seamless or welded) and heat treatment
  •   Size, wall thickness and quantity of tubes covered
  •   Mechanical tests: tensile, flattening, flaring and bend results
  •   Hydraulic test pressure applied to the tubes
  •   Signatures of the maker and the Inspecting Authority, or certification as a Well Known Tube Maker

IBR Tubes: FAQs

What is an IBR tube?

An IBR tube is a steel tube that is manufactured, tested and certified to meet the Indian Boiler Regulations, 1950 (IBR), so it can be used in boilers, superheaters and economisers in India. IBR is not a material grade: the tube is made to a standard such as ASME SA192, SA210 or SA213 and is then certified on IBR Form III-B.

What is IBR Form III-B?

Form III-B is the IBR Certificate of Manufacture and Test for tubes. It records the tube and steel maker, heat number, chemical composition, manufacturing process, sizes, mechanical test results and hydraulic test pressure, and is signed by the maker and the Inspecting Authority or issued by a Well Known Tube Maker. Pipes are certified on the separate Form III-A.

What is the difference between IBR and non-IBR tubes?

The material grade can be identical. The difference is certification: an IBR tube comes with Form III-B, which the Boiler Inspector accepts for boilers registered in India. A non-IBR tube has only the normal mill test certificate and cannot be used where IBR applies, though it is fine for heat exchangers and process equipment outside IBR.

Which tube grades are supplied with IBR certification?

The most common IBR tubes are carbon steel ASME SA192 and SA210 Grade A1 and C for water walls, economisers and boiler banks, SA178 ERW tubes for fire-tube boilers, and alloy steel SA213 T11, T22 and T91 for superheaters and reheaters. Stainless steel SA213 TP304H and TP347H tubes can also be supplied with IBR when required.

Is IBR certification still required after the Boilers Act, 2025?

The Boilers Act, 2025 came into force on 1 May 2025 and replaced the Boilers Act, 1923. Under its saving provisions, regulations made under the old Act continue to apply until new ones are notified, so boiler inspectors and buyers continue to ask for IBR certification of tubes. Check with your State Boiler Inspectorate for the current requirements on your project.

How do I order IBR tubes?

Send us the grade (for example SA210 A1 or SA213 T22), outside diameter, wall thickness and whether it is minimum or average wall, length and quantity, and state that IBR Form III-B is required. Tell us if a specific Inspecting Authority must witness the inspection, so it can be arranged with the order.

IBR Tube Supply Across India & Export

IBR certification applies to boilers in India, so we supply IBR tubes to boiler makers and plants across Maharashtra, Gujarat, Karnataka, Tamil Nadu, Uttar Pradesh, Andhra Pradesh, Telangana, Madhya Pradesh and other states. For export projects, we supply the same boiler tube grades with EN 10204 3.1 / 3.2 certification to the Middle East, Africa and South-East Asia.
