Boiler Tubes Manufacturer in India

Boiler Tubes Specification

Our boiler tubes come in a wide range of diameters, walls, grades, and conditions. As a boiler tubes manufacturer, we build to your standard, drawing, and delivery condition, and we cut, bend, swage, and pack each order to your needs.

Boiler Tube Standards and Specifications

A standard fixes the grade, size limits, tolerance, testing, and delivery condition of the tube. We make boiler tubes to the codes below and add third-party inspection on request.

Common Materials

Carbon steel is widely used for boiler tubes because it offers good strength and cost efficiency in lower-temperature sections. ASTM A192, A210, and A178 grades are commonly used for economisers, water walls, and boiler banks.

For higher-temperature service, alloy steel grades such as ASTM A213 T11, T12, T22, T91, and T92 provide better resistance to creep and oxidation. Stainless steel grades including ASTM A213 TP304H, TP316H, TP321H, and TP347H are used where higher steam temperatures and corrosion resistance are required.

As a boiler tubes supplier, we provide these materials in different grades and specifications according to the required boiler design and applicable standards. Material selection depends on the tube metal temperature, steam pressure, operating conditions, and boiler code.

Boiler Tubes Material and Grades

Each grade below comes with a mill test certificate that lists its chemistry, UNS number, and standard. If your project needs a grade that is not on this list, we can supply it against a custom specification.

What Is the Difference Between Seamless and ERW Boiler Tubes?

The main difference is the seam. Seamless boiler tubes have none, and ERW boiler tubes carry one heat-treated weld. Seamless tubes handle the highest pressures and temperatures, so superheaters, reheaters, and high-pressure water walls use them. ERW tubes cost less, hold a very even wall, and serve economisers, boiler banks, fire tubes, and air heaters at lower pressure.

Choose seamless when metal temperature and steam pressure run high. Choose ERW when the duty is moderate and cost matters. Also remember that boiler codes apply a weld joint factor to welded tubes, so the allowed pressure can be lower than for the same seamless tube.

Boiler Tubes Chemical Composition

Chemistry sets how strong, weldable, and creep resistant a grade is. Values are weight percent, maximum unless a range shows.

Stainless Steel Boiler Tubes (ASTM A213 H Grades)

Boiler Tubes Mechanical Properties

Mechanical properties show how much load a boiler tube carries before it stretches (yield) or breaks (tensile). Values are minimum unless marked max.

Boiler Tube Size and Weight Chart

Boiler tubes are ordered by outside diameter and wall thickness. The chart shows weight in kg per metre for carbon steel. Stainless steel tube weighs about 2% more.

To work out the weight of any size, use Weight (kg/m) = (OD − Wall) × Wall × 0.02466, with both values in mm.

Available Sizes, Dimensions and Tolerances

We supply boiler tubes from 3/4" to 6" OD, in walls from 2.0 mm to 10 mm. Boiler tubes do not use schedule numbers. You order them by outside diameter and wall thickness, and the standard sets how far each can vary. For boiler tubes, ask whether the tolerance applies to the minimum wall or the average wall, because the two are not the same and boiler makers design to the minimum wall.

Standard lengths are 6 m, 9 m, and 12 m, plus random lengths and exact cut lengths. As a boiler tubes supplier in India, we hold ready stock of popular sizes, subject to availability, and we bend, swage, and end-form tubes on request.

Boiler Tubes We Manufacture and Supply

Our boiler tube range includes carbon steel seamless tubes, ERW boiler tubes, alloy steel tubes, and stainless steel tubes for different boiler and heat-transfer applications. We manufacture and supply water wall tubes, boiler bank tubes, economiser tubes, superheater tubes, reheater tubes, fire tubes, and air heater tubes.

Our boiler tubes supplier service covers different grades, sizes, wall thicknesses, and configurations. We also supply bent tubes, swaged tubes, and cut-to-length tubes with the required end finish, identification marking, inspection records, and test certificates according to the applicable standard.

We support power plants, process boilers, refineries, and industrial heating systems with suitable material, testing, documentation, and packing based on each order requirement.

Applications of Boiler Tubes

• Thermal Power Plants: Carry water and steam in water walls, superheaters, and reheaters.
• Industrial and Captive Boilers: Serve sugar, paper, textile, and chemical plants that make their own steam.
• Waste Heat Recovery Boilers: Recover heat from furnaces, kilns, and gas turbines.
• Refineries and Petrochemical Plants: Handle steam generation and process heating.
• Fertilizer and Chemical Plants: Run steam and heat transfer in high-pressure units.
• Fire Tube and Package Boilers: Carry hot gas through the shell in compact units.
• Marine and Shipboard Boilers: Generate steam for propulsion and heating on ships.
• Boiler Retubing and Maintenance: Replace worn tubes during shutdowns.
