Our Products Range
SS Heat Exchanger Tube Supplier for Boilers and Condensers
EFFICIENT LONG-LASTING HEAT TRANSFER HEAT EXCHANGER TUBES
As a leading Stainless Steel Heat Exchanger tube manufacturer in India, Eramets Steel Alloys Pvt. Ltd manufactures seamless, welded and U bends tubes for refineries, power plants, and the chemical industry. Our tubes are manufactured as per ASTM A213, A249, A269, A688 and the ASME Boiler and Pressure Vessel Code. Thus our tubes would directly fit into your shell and tube heat exchangers, condensers, feedwater heaters and boilers.
We take pride in the fact that our tubes are engineered for heat transfer efficiency, corrosion resistance and long service life. Close dimensional tolerances and smooth tube walls help resist fouling of the equipment and help heat transfer equipment operate longer between shutdowns.
HEAT EXCHANGER TUBES FOR BOILERS AND CONDENSERS AND PROCESS HEAT EXCHANGERS
We provide seamless and welded alternatives for your heat exchanger tube needs.
Seamless Heat Exchanger Tubes (ASTM A213)
Seamless Heat Exchanger Tubes are produced from the cold draw or pilgering of solid hollows to the final size and solution annealed. This removes the weld seam and results in uniform strength around the entire circumference of the tube. They are recommended for use in high pressure boilers and other critical services.
Welded Heat Exchanger Tubes (ASTM A249/A688)
Welded Heat Exchanger Tubes are produced by automatic TIG welding of strip, resulting in a cold worked weld bead with a structure very close to the parent metal. They also have good wall thickness tolerance and a smooth surface for better heat transfer. Compared to Seamless Heat Exchanger Tubes, they are less expensive, and thus are used in condensers, feedwater heaters and HVAC systems.
| Factor | Seamless Tubes | Welded Tubes |
|---|---|---|
| Pressure and temperature |
Higher | Moderate to high |
| Wall thickness accuracy |
Good | Excellent |
| Cost | Higher | Lower |
| Long lengths | Limited by drawing | Very long lengths possible |
| Typical use | Boilers, refineries, critical service | Condensers, feedwater heaters, HVAC |
Stainless Steel Heat Exchanger Tubes
U-Bends provide greater freedom for thermal expansion and contraction of the tube bundle and are therefore used in feedwater heaters, steam generators and some types of shell and tube exchangers with a single tube sheet. We supply U-bend tubes as per specifications of ASTM A213, A249 and A688 in seamless and welded condition [confirm in-house U-bending].
U-Bends are formed with controlled wall thinning and ovality. On special requests, stress relief or solution annealing of the bent portion of the U-tube is carried out, and the tubes are hydrostatically tested after bending. The tubes are supplied row-wise, tagged and packed in sturdy wooden cases. This ensures that the tubes reach the customer’s shop ready for assembly.

| Sulphuric and phosphoric acid service | SS 904L |
Our Process as Stainless Steel Heat Exchanger Tube Manufacturer in India
Heat exchanger tubes have to withstand heat, pressure and corrosion so we manage all stages of production.
1. Raw Material Check – Hollows and strips are examined for chemistry and heat and traceability.
2. Forming – Seamless tubes are pilgered and cold drawn and welded tubes are roll formed and TIG welded.
3. Solution Annealing – Stainless steel tubes are bright annealed and full annealed and pickled to restore full corrosion resistance.
4. Straightening and Cutting – Tubes are straightened and cut to length. U-bends are made where required.
5. Testing – Non-destructive tests, hydrostatic test, dimensional and mechanical tests are done as per the order standards.
6. Marking and Packing – Each tube is marked with its grade, size, standard and heat number and then capped and packed.
Quality Testing and Inspection
Each of Eramets Steel Alloys Pvt. Ltd.’s heat exchanger tubes is thoroughly tested, including the following:
– Hydrostatic pressure testing
– Eddy current testing, ASTM A1016
– Ultrasonic testing
– Positive Material Identification (PMI)
– Chemical composition analysis
– Tensile testing and hardness testing
– Flattening, flaring, and flange testing
– Reverse bend test for welded tubes
– Intergranular corrosion test (ASTM A262) upon request
– Surface roughness test
A Mill Test Certificate is included with each shipment, and 3.1 and 3.2 certification by an independent third party is available upon request.
Heat Exchanger Tube Operating Temperature
The safe operating temperature of a heat exchanger tube varies with grade and wall thickness and is related to the design code and the pressure for which it was designed. Stainless steels, such as 304L and 316L, retain their toughness at temperatures as low as -196 °C. Stabilized grades, such as 321 and 347 and heat-resisting grades, such as 310S are chosen for high temperature services. Allowable stresses at design temperatures are given in ASME Section II. Please share your design temperature and pressure and we will suggest an appropriate grade.
