Steel line pipe has been used successfully for decades now in the transportation of gases, flammable liquids and solids. Given the high pressure levels frequently involved in the transportation of these media, steel is the optimum pipe material and it remains unparalleled in terms of safety and reliability for a long service life. As a leading specialist in HFI-welded pipe, Supplier Line Pipe can be a reliable partner to the oil and gas industry around the globe.
Manufacture LINE PIPE can draw on decades of experience in the manufacture of welded steel material. This heats up the open pipe rapidly, raising the strip edges to welding temperature as they arrive at the apex. Pressure rolls force the heated edges together, completing the weld. Our state-of-the-art production equipment and processes, a wide range of coating and lining systems, plus top-quality service all along fulfilling our customers’ individual needs and wishes in terms of safety, environmental protection and project-specific demands. With a weld efficiency factor of v = 1.0, our products meet the highest requirements of international standards such as EN, API, ISO, GOST, and DNV Rules, in conjunction with the most demanding specifications from renowned national and international oil and gas companies.

This mill produces pipes with length up to 18 m with 8 to 24 in diameters and up to 20.6 mm thickness. Pipes produced in this mill are in accordance with international standards such as API 5L, ISO 3183 and customer requisition such as: IPS-M-PI-190 In production processes, steel strip in form of coil are put at the beginning of feed line and irregular end of coils are cut & welded. Following to milling of longitudinal edges of coil, strip surface is tested by ultrasonic and strip edges are welded by high frequency inductive welding (HFI). While moving through automated ultrasonic system (to indicate welding faults), longitudinal welding seam is heat treated and pipes are cut in required length. Then pipe ends circumference is controlled by ultrasonic system and are beveled. Then pipe is tested by hydro-static machine and finally pipe longitudinal welding is tested by ultrasonic and then weighing and marking can be delivered to the customer. According to market demand it is also possible to produce heavy profiles in square and rectangular forms with maximum dimensions of 500×500 mm and 600×400 mm. These products are produced in accordance with international standards such as EN 10219.
