Note: We aslo have had a history of producing stainless steel tube in coil for well over a dozen years and we have two lines for the production of continuous weldingpipes. On the basis of complete equipment and leading technology, the company has aslo introduced world first-class brigt annealing technology, which makes it possible to conduct stainless steel pipe online softening treatment. Besides, we aslo have testing & inspecting facilities for flattening, tube end expansion, cold benging as well as for hardness, tensile and 100% airtightness tests. With reliable quality ang reasonable prices, 80% of our coil pipe products are exported to countries all over the world.
