Advanced ERW Pipe Mill Line
With international advanced equipment, testing method and automative control technology, this production line has an annual production capacity of 500,000 tons.

The Quality Control System
We always adhere to the policy of quality first and keep to the path of vitalizing our company with science and technology. We have a first class labortary, where mechanical, chemical and metallographic examinations can be undertaken. We also have advanced online ultra-sonic testing equipment and hydrostatic tester. We adopt strict quality control according to international standard.
Testing played a necessary role in production and after production. We use high-quality facilities and a complete set of testing system such as X-ray flaw detectors, ultrasonic flaw hydrostatic pressure testing machines, tensile testing machines, metallographic analyzers, physics and chemistry laboratories and other detection systems. Our high-quality production testing procedures enable our production and testing to meet the required standards and to satisfy our customers.
