LSAW Workshop

LSAW Workshop is used for pipe diameters from 16 to 64 inches. In the LSAW pipe workshop, the processing is done by cold forming of thick carbon steel plates. Among the forming processes available, Union Steel focuses on UOE and JCOE technologies. We supply equipment for all important process steps from sheet preparation to forming, welding, testing and finishing. Including not only the core machine, but also all upstream and downstream process steps required to produce large-diameter pipes. Our plants stand for medium to high production volumes of high product quality, flexible and cost-effective processes, precise dimensions and tight piping tolerances.

ERW Workshop

Supplying all core machines for ERW workshop, our products are renowned for their workmanship precision. The perfect combination of know-how, innovation, automation and digitalization ensures the production of high precision tubing, line pipe, casing, tubing and drill pipe as well as structural tubes with round, square and rectangular cross sections. These flexible factory lines can manufacture welded pipes with good processing quality and high-speed assembly accuracy. Covers product diameters up to 710 mm and wall thicknesses

SSAW Workshop

The SSAW workshop is used to produce spiral welded pipe between 15 and 100 inches in diameter. Spiral pipe is the strongest among welded pipes. The spiral welded pipe manufacturing process is not only one of the most efficient methods of producing steel pipes, but also offers a high degree of flexibility in the production range in terms of diameter and wall thickness. Our SSAW workshop can produce spiral tubing through the traditional 1st stage process as well as 2nd stage process (also known as off-line process). The final product is more than twice as resistant to extrusion as LSAW or ERW pipe.

SMLS Workshop

At present, Union Steel Industry Co.,Ltd owns 3 sets of hot rolled seamless steel pipe production line and 2 sets of hot expanded seamless steel pipe production line with annual production capacity of 200,000 tons, the size range is from 73mm to 630mm. Its physical and chemical labs cab conduct various physical and chemical tests and experiments for steel pipes, and are equipped with eddy current flaw detectors,leakage fault detection and ultrasonic crack detectors etc. For high, medium and low pressure seamless steel pipes and petroleum casing pipes with a full range of inspection measures, capable to meet various standard test and inspection requirements for steel pipes.
