Stainless Steel Tube Coils

They adopt healthy stainless steel materials 304, 304L and 316L, with the maximum length of over 1000 meters. They can go through lighting anneal, and ensure no leakage after passing 100% inspection. They are packaged in coils, which are applicable to foodstuff, drinks, mechanical structure and liquid transportation. The main specifications are 5/16" x 0.02" (8mm x 0.5mm). Features: 1) Production Standard :ASTM A269;ASTM A249,& 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 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 welding pipes. On the basis of complete equipment and leading technology, the company has world first-class bright annealing technology, whichmakes it possible to conduct stainless steel pipe online softening treatment. Besides, we also have testing & inspecting facilities for flattening, tube end expansion, cold bending as well as for hardness, tensile and 100% air tightness tests. With reliable quality and reasonable prices, 80% of our coil pipe products are exported to countries all over the world.As far to 5 years, our company has been the largest supplier in the world which export stainless steel coiled tube for beer dispensing/beverage cooling.
