In polished stainless steel tube (201/202 201/202 201/202 / l/l) : inside weld leveling treatment, solid solution treatment, the inner surface electrolytic polishing. Used for milk and food industry. The pharmaceutical industry. Liquid transportation. Performance characteristics; Wall surface roughness Ra 0.2 above, hanging residual less easy to clean, prevent bacteria growth and electrolytic polishing with Tun role, internal anti-corrosion performance is good. Leveling in stainless steel pipe (201/202 201/202 201/202 / l/l) : heat treatment after welding, the leveling. Pickling. And then to water pressure test. For the heater. Boiler. Heat exchanger and cold suspected. Performance characteristics; End of tube wall smooth. Water resistance, can withstand the high velocity of water erosion. After solid solution treatment. Bead and the basic mechanical properties. Anti-corrosion performance, excellent machining performance. To "quality to survive, credibility and development. The pursuit of excellence, sustainable operation, the principle of mutual benefit and reciprocity". To sync with the masses of customers. Side by side to create happy tomorrow hand in hand. Warmly welcome the merchants at home and abroad calls, letters, come to negotiate orders or sample to figure, to build.
