For more information galvanized flange galvanized flanges: zinc processing costs 1 flange, paper processing costs: the cost of hot-dip galvanized anti-rust paint coating than other low cost; 2, durable: Suburb environment flanges, hot dip galvanized thickness standard can be maintained without having to repair more than 50 years; in urban areas or coastal areas, the standard hot dip galvanized layer can be maintained for 20 years without repair; 3, reliability: between zinc coating and steel are metallurgically bonded, become a part of the steel surface, so the coating durability is more reliable; 4, coating toughness: the zinc coating to form a special metallurgical structure of large flange This structure can withstand during transportation and use of mechanical damage; 5, comprehensive protection: each part of the plated parts can be coated with zinc flange large volumes, even in depression, sharp corners and hiding place can be fully protection; 6, saving time and effort: galvanizing process than other coatings construction method is more efficient, and to avoid the site of the installation in FIG brush required. For more information loose flange: the loose flange using the flange bearing on the tube end flanges on the pipe end of the movable flange, steel ring and so on. Steel ring or flange sealing surface is, the role of the flange is pressed against them. This shows due to being blocked by the steel ring or flange welded flange, loose flange is not in contact with the medium. Loose flange for steel, aluminum and other non-ferrous metals and acid-resistant stainless steel container connections and corrosion on the pipeline. Loose flange can be active flange piece, generally supporting the water supply and drainage fittings (on expansion joints most common), expansion joints at both ends have a flange on the factory when the factory directly with project pipeline, equipment bolted. It is to bring the kind of flange looper. Generally used in the pipe, in that case, loose bolt can be rotated on both sides of the pipe, and then tighten. It can be more convenient removable pipe. Loose flange also called Looper flange. Large volumes flange flange _ _ Bo Yan Pipe Industry (view) provided by the Yanshan Xian Yan Bo Industry Co., Ltd. Yanshan County Bo Yan Pipe Co., Ltd.
