Our capabilities are unique in the seamless tube industry in that we offer a totally integrated process for all aspects of tube production. This includes the manufacturing of customized alloy steels in our own mills and the production of value-added tubular products from finished tubes at our facilities, plus end-to-end logistical solutions.

ISMT Limited’s subsidiaries include ISMT Europe ( Structo Hydraulics( Structo Hydraulics, with production facility in Sweden, is among Europe's leading suppliers of tubes and engineering production for the hydraulic industry.

Steel: For your customized alloy steel requirements, our team of engineers and metallurgists work with you to develop steels that are optimized for your engineering needs. We start by smelting high-quality scrap metals in an Electric Arc Furnace and then take the added step of Vacuum-Degassing to ensure that our steel is as clean as possible. All our steel meets SAE, ASTM, AISI, API and other well-known standards across industries.

Tubes: ISMT is one of the few companies in the world to have installed a state-of-the-art SMS Meer PQF® Mill for the manufacture of seamless tubes. ISMT now operates one PQF® mill and three Mannesmann equipped Assel mills, making ISMT one of the largest and most diversified producers of specialized seamless tubes worldwide with a capacity of 475,000 metric tons of tubes per annum. We manufacture hot-rolled and cold-finished carbon and alloy steel seamless tubes from 1/4 inches to 10 6/8 inches (6mm to 273mm). Finished tubes can then be delivered “as is” or be further modified for your final requirements by machining, heat-treating, annealing, swaging, upsetting or other value-added processes. As a result, our tubes are ideal for applications such as the manufacturing of bearings, automobile parts, drill rods, hydraulic cylinders, gas cylinders, boilers, heat-exchangers, etc.

Value-added products: Apart from tubes, we also manufacture a wide range of value-added products for the above industries. These include items such as bearing rings, gear blanks, gear shifter sleeves, cages for constant velocity joints, swaged and machined axles, API couplings, and a host of similar products.

R&D: Each year we invest heavily in research and in the development of new processes and products while keeping an eye towards reducing costs and improving quality. Our R&D and product support teams work closely with our customers to better understand their needs so we can tailor products that can help improve their productivity.
