coiled stainless steel tube for condensser

Features: 1) Production Standard :ASTM A269;Enterprise Standard 2) Material of commonly used stainless steel:TP304, TP316L; Material of other stainless steel: TP304L 3) Product applications and applicable field: refrigerating equipment, evaporators, gas/liquid conveying, condensers, beverage machinery 4)General product status at delivery: semi-hard status/bright annealing soft status 5) Specification range:outer diameter:6mm-19mm; 6) Annual production capacity: 600 tons 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, whichmakes 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.
