OCTG Products
Seamless Tubes and Tube based Products
for Applications in the Oil & Gas Industries
 
ISMT manufactures a variety of OCTG products such as Casings, Tubings, Line Pipes, Coupling Stock, Finished Coupling (API) and specialized tubes for mechanical applications such as the manufacture of perforator guns, fishing tools, etc; These items can be customized to the requirements of individual customers in terms of heat-treatment and end finishes.

The American Petroleum Institute has certified ISMT's products (API License No.5CT-0395, 5CT-0123, 5L-0102, 5L-0296, 5-D0018) and awarded ISMT the right to use the API monogram for specification API 5L, 5CT and 5D – plain ended pipes.
 
TOTAL PROCESS CONTROL
At ISMT, we believe the only way to guarantee quality is to stand responsible for the entire production process. For that reason, we produce 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 few select manufacturers globally to be approved by SKF & 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 and hollow bars.

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. As regards to experience, we have perhaps, the most technically qualified team anywhere in the world – the OCTG products reflect this experience.
