ISMT Envisioning Saleable Capacity of 2.5 lakh MT for Seamless Tubes


Started in 1977, with a unique combination of assel mills, a premium quality finishing(PQF) mill, and an integrated steel manufacturing facility, Indian Seamless Metal Tubes (ISMT) is one of the most diversified manufacturers of specialized seamless tubes. ISMT produces both hot-finished as well as cold-finished seamless tubes catering to applications such as the manufacture of auto-components, bearing races, OCTG products, drill rods, boilers, heat-exchangers, etc. Tube & Pipe India feels fortunate to converse with Mr. Nishikant Ektare, Managing Director, ISMT as he elaborates on the business plans to aggressively push and maximize capacity utilization of the steel and tube plant and invest CAPEX for various debottlenecking operations.

Tube & Pipe India: Please tell us about Indian Seamless Metal Tubes (ISMT) Limited, highlighting the company’s business journey, major milestones and achievements.

Nishikant Ektare: ISMT was started by a group of technocrats for production of bearing tubes through seamless route as an import substitute in 1977 and the first plant at Ahmednagar commenced operation in 1980 with 1 assel mill and an installed capacity of 15,000 MTPA. Later the company expanded by setting up another mill of similar capacity as the demand for tubes was continuously rising. The company as part of its strategy to be self-reliant for the raw material- steel billets, decided to set up a steel plant and become a fully integrated manufacturer in 1993 when the GoI liberalized the economy. The steel plant then christened ISSAL (Indian Seamless Steels & Alloys Ltd) was commissioned with an installed capacity of 3.0 Lakh MTPA commenced commercial production in 1995. Subsequently, the company also acquired KSTL (Kalyani Seamless Tubes Ltd.) from the Kalyani group in 2000 thus marking the foray into larger diameter tubes for varied application. In the year 2005, all the 3 companies were merged and the new entity ISMT Ltd was formed. ISMT Ltd., also acquired Structo Hydraulics AB in Sweden to cater to the hydraulic segment in Europe and was a leading supplier to the large OEMs.

The company went through severe financial crises with Chinese dumping and the market slow down post 2012 and was reeling under losses and strained operations. In March 2022, Kirloskar Ferrous acquired a majority stake in ISMT Ltd and with this the new management came on board. The management went about addressing the major concerns facing the company viz restoring positive net worth, negotiated sourcing of RM, improving customer satisfaction, aggressive market push for volumes to load the plants for full capacity utilization and also focusing on costs with a view to improve contribution. The result of these actions helped the company to turnaround in the very 1st quarter after takeover.

TPI: Kindly give a brief walkthrough of the manufacturing facilities, infrastructure and machinery setup along with the production capacity.

NE: Steel Plant at Jejuri: The company has installed a EAF (electric arc furnace) with 55 MT capacity capable of making 18 to 20 heats per day with downstream facilities of LRF( ladle refining furnace), VD/VOD (vacuum degassing), concast, rolling mill, heat treatment furnaces and supporting infrastructure like the fume extraction, oxygen plant, laboratory etc to effectively produce 3.0 Lakh MT of billets and about 1.50 lakh MT of rolled bars. About 70% of the production is for captive consumption and the balance is sold to the market for bearing and auto application. We cast billets in dia 180, 200 and 225 mm and rolled bars from 25 mm to 90 mm with varied alloy compositions. We also make super critical T9 and T91 grades for the boiler application.

Tube Plant at Nagar: The Company has an annual installed capacity of 60,000 MT for tube rolling and around 55,000 MT for finished tubes. The plant has 2 assel mills with the associated heating furnaces, finishing lines, non-destructive testing and allied facilities. The Nagar plant caters to smaller dia tubes in the size range of 16 mm to 140 mm and has the cold draw, cold pilger and the hot finish tube manufacturing facilities. The plant is equipped with all the finishing and testing equipments including heat treatment and handling infrastructure. The Nagar plant also has 2 sub divisions wherein smaller dia tubes and components are manufactured. The major segments serviced by the Nagar plant is automotive, bearing and mining industry.

Tube Plant at Baramati: The company has an installed capacity of 3.0 Lakh MT of rolling and around 1.50 lakh MT for finished tubes. The plant has 1 assel mill capable of producing tubes from 7” to 10” and a PQF mill capable of producing from 1.5” to 5.5”. The associated infrastructure of handling, heat treatment, testing facilities are available for each of the types of tubes being manufactured whether they are cold drawn, casing, tubing or hot finish.

There is also huge demand coming in from North America and the Middle-east owing to the strategies of these countries to have an alternative to China. Indian seamless tube manufacturers will have to build capabilities in product development for a wide range of applications like geo-thermal and specialized oil & gas to partake in these business opportunities.

Post opening up of China after COVID 19 by October 2022, we have witnessed huge quantities of seamless tubes and rings coming into India at substantially low prices thus de-stabilizing the business in the short term.
