1), steel finned tube convector heating system should meet the operating pressure and system pressure requirements for steel finned tube convectors, should comply with national or industry standards. 2), in open heating systems and high humidity rooms (such as bathrooms, swimming) should not be used just made radiator. 3), the test results and data products were identified by checking the sample (test product requirements for product sampling, test reports within nearly two years). 4), the manufacturer shall provide steel finned tube convector radiator water resistance characteristics of the data. 5) of the steel finned tube convector radiator appearance inspection. Each welding parts should be smooth, machined surface at the interface should be fine and to ensure squareness and flatness. 6), the product is suitable for hot water heat medium working pressure 1.0MPa, steam heat medium 0.3MPa. 7), should check whether the radiator with excellent quality steel (on the low-pressure fluid delivery with seamless steel tube or pipe) bonding process mine air heating radiator, steel pipes and fins between tightness. First, aluminum composite fin tube Overview: aluminum composite fin tube processing technology from aluminum and copper to process double metal composite pipe, and then by mechanical rolling, the physical characteristics of the plant with the use of aluminum finned radiator, made with a core of brass tube and cold rolled aluminum fins closely as one of the finned tube. When aluminum composite pipe radiator fins are widely used in heating and air conditioning to cool and wet-engineering the outer surface of the fin easy to exclude condensate, in the dry heat exchange heating and other occasions difficult knot dust fouling. Second, aluminum composite fin tube Features: 1. With combined with tight, small resistance, good heat transfer performance; 2. High intensity, low flow losses; 3. Anti-corrosion strong, hot and cold working conditions in the long term is not easy to deform long working life.
