Its strategic priorities are focused on supplying the Angolan markets with high quality seamless tube and value added products.
The majority of the hot rolled products are supplied under the API Monogram License programmes for Line Pipe and OCTG products.
The seamless tubes are manufactured and tested in accordance with EN, ISO and API standards and meet the requirements of the petrochemical oil and gas industries. They are manufactured via a mini-mill, incorporating a cone type piercer, a multi-stand pipe mill and in-line downstream finishing facility. The manufacturing facility consists of a rotary hearth furnace, a cone-type rotary piercer and a multi-stand pipe mill. In addition it has a 22-stand stretch reducer followed by straightening, cutting and beveling facilities, as well as an electro-magnetic, ultrasonic and hydrostatic testing units.
The seamless product range includes line pipe for use in oil and gas transportation, carbon and low alloy for use in process and pressure piping applications, OCTG products and precision tube for mechanical applications.
