Hydraulic pressure lines are subject to high static as well as dynamic pressures and often to pressure shocks. The only way to guarantee that our tubes will perform without a single field failure is to control the entire production process. For this reason we start with producing all our steel in-house. We bring to bear over 20 years of experience in manufacturing high-grade Bearing steel to all our manufacturing processes and to all our steel products (we are among a few select manufacturers globally to be approved by SKF and FAG for the supply of Bearing steels).

We produce our steel through the Electric arc furnace route. The raw material mix is chosen and prepared carefully to ensure the highest standards of cleanliness. All heats are 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 tubes.

The manufacture of precision seamless tubes is as much a matter of equipment as it is of experience and process technology. At ISMT, we believe in investing in the finest of equipment.For making seamless tubes we operate three Assel Mills, one PQF Mill, Pilger Mills, and Cold Draw Benches.

Our tube-mills are imported from Shloemann Mannesman in Germany and incorporate the best in technology. With regards to experience, our team is amongst the most technically qualified anywhere in the world - the tubes that we produce for use in Hydraulic and Pneumatic pressure lines reflect this experience.
