SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. There are 12 sets of modernized production line of SSAW pipe. The annual yield of SSAW pipe with outside diameter 219mm-3620mm, wall thickness 5-25.4mm and steel grade B-X80 is 1,000,000 tons. its two steel pipe production lines, one for spiral submerged arc welded (SAW) steel pipe and one for <span style=”line-height:1.5;”>longitudinal submerged arc welded (SAW) steel pipe, are respectively comprised of two sets of main machines and 1 set of sizing equipment. The annual output comes to 120,000 ton for spiral SAW pipe and 200,000 ton for longitudinal SAW pipe.

At present, Hunan Great Steel Pipe 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.

High-frequency longitudinally welded pipe production line is mainly used for the production of welded steel pipe of φ8 ~ φ610 mm and wall thickness of 0.5~ 20mm as well as the production of square, rectangular, and other custom seamless pipe profile, Carbon steel pipe, ERW steel Tube. The line can manufacture welded pipes with good quality machining and high precision assembling at high speed.

Hunan Great Steel Pipe Co.,Ltd newest JCOE production line officially launched its production October 16, 2009. The company spent less than one year and a half commencing from the groundBreaking on April 19, 2008 to the load commissioning on August 31, 2009, which bring a new revolution of JCOE steel pipe in the world. The LSAW steel pipe production line provides advanced equipment and technology with the annual designed capacity of up to 200,000 tons, The manufacturing execution system control system is adopted to manage the production and dispatching. And the supervisory control and data acqusition system is adopted to collect data and monitor the process to realize the intergrated and real-time production management.
