Special Tubes for Power Generation
and Energy Industry
ISMT manufactures the entire spectrum of seamless tubes required by the power generation and energy industries. Our tubes are used in manufacturing boilers, heat exchangers, super-heaters, heat recovery, steam generators and other heat transfer devices.
All ISMT tubes embody over 20 years of experience in the manufacture of application specific tubes for the power generation industry. We melt all our steel in-house and our tubes are manufactured to the most stringent industry standards.
Our research and product development teams have worked closely with our customers to develop a very wide range of products.
- Size range extending upto 273 mm dia (10 inches)
- Multi-rifled tubes (both A and B series)
- Creep resistant T – series tubes including T1, T5, T11, T22, T91, T92 and T23 grades
- Long length tubes upto 25.5 meters
- Cold drawn tubes
With extensive years of experience in supplying tubes to the power generation sector, we are fully aware of the criticality of these tubes. Therefore, we manufacture all our steel in-house through the electric arc furnace route maintaining complete control of the entire production process.
The raw material mix is chosen and prepared carefully to ensure the highest standards of cleanliness. All heats are fully killed, ladle refined and vacuum degassed before continuous casting and rolling. Right through the production process, we maintain full traceability of the material and a record of the tightly controlled process parameters. This ultra-clean steel forms the starting point for the manufacture of our seamless tubes. Stringent process control continues through the tube rolling as well as final heat treatment process so that we are able to deliver tubes with smooth ID quality, uniform grain structure, and excellent straightness.
The manufacture of precision seamless tubes is as much a matter of equipment as it is of experience and process technology. We believe in investing in the finest of equipment. For manufacturing seamless tubes, we operate three Assel Mills and a brand new PQF Mill. We also have a number of cold draw benches for producing cold draw tubes. Our tube-mills are from Shloemann Mannesman in Germany and incorporate the best technology. The state-of-art equipment is backed by an operating team that is amongst the most technically qualified anywhere in the world – the tubes that we produce for the power generation and energy industries reflect this experience.

Each tube is oiled, internally as well as externally, and then packed into hexagonal bundles. This ensures that the tubes are protected from corrosion and that they retain their straightness during transport. Based on your requirements, we can provide end caps and also wrap the bundles in LDPE sheets
All our tubes are tested as per customer requirements. Our testing facilities include full-body Ultrasonic, Eddy Current, Leakage-Flux and Hydro-testing.
ISMT is unique in that we operate to a weekly manufacturing cycle; we can go from scrap to finished tubes of any size or grade, ready for dispatch, in less than 15 days. As a result, we offer the tightest delivery lead times in the industry.
We produce seamless tubes with upto an outer diameter of sizes 273 mm (10 inches). In addition, we can produce any customized size as per the graphs below:
