Resistance welded pipe and the widest range of application is the first professional production, the production unit (2000), the highest yield at most (accounts for some 80% of the total output of welded pipe can) of steel pipe varieties, product specifications for Ф 20 ~ 610 mm, played an important role in national economic construction.
Since eighty s of the 20th century, there are about more than 30 sets of ERW 219 ~ 610 mm unitimported advanced technology from abroad. After many years of production practice, equipment technical level has improved greatly, also continue to improve product quality.
Because of its less investment, quick effect, application range and developing rapidly. Along with the development of the plank CSP production technology, with low cost, reliable quality of raw materials, and created good conditions for its further development. This part of the product by the fluid transport, structure fields to the seamless tube pipe, line pipe in the field of application development.
