Ahana International Sale a variety of OCTG products such as casings, tubing, line pipe, coupling stock. These items can be customized to the requirements of individual customers in terms of heat-treatment and finishes. For all of these products the steel used is produced by the electric arc furnace route and is fully killed.
The tubes are heat treated in controlled parameter heat treatment furnaces for ease of further working like welding, bending, etc. In order to minimize pressure losses the tubes are manufactured to tight tolerances with an excellent finish on both the inner and outer surfaces. These tubes are hydro and leakage flux tested to ensure their structural integrity.
The American Petroleum Institute has certified products (API License No. 5CT – 0395, 5CT- 0123, 5L-0102, 5L-0296) and awarded the right to use the API monogram for specifications API5L, 5CT and 5D plain ended pipes.
