Detailed Product Description: | Flange _ Hebei billion in gold professional production pipeline flange _ welded flange suppliers from Hebei billion in gold piping. Flange | Hebei billion of professional production pipeline flanges | welded flange suppliers Hebei billion of Pipe Manufacturing Co., Ltd. (www.yijinguanjian.com) 2014 年 new upgrade launched in flange size parameters, PN is the nominal , said the unit is MPa in the International System of Units, the engineering units are kgf / cm2. Nominal determine not only according to the maximum working pressure welded flange suppliers, need to work according to the highest temperatures and material properties, rather than just meet more than nominal working pressure. In domestic 1.0 2.0 5.0 6.8 10.0 15.0 25.0 42.0MPa generally these data, the international 150Lb 300Lb 400Lb 600 900 1500 2500lb. There argument is flange DN flange, DN is a parameter flange dimensions, these two parameters have standard (GB). PN is the nominal Nominal refers to the water pipe 20 ℃ operating pressure. When applied together flange and pipe, flanges should determine nominal working pressure pipe installed the same. The design of such a pipe installed when the reservation is 1.0MPa, then use all the flanges of the piping system is of 1.0MPa. Nominal flange flange can already tell you that the use of pressure. The design of the design pressure of not more than nominal flange can, because flange design has been considered a strength issue when welded flange suppliers, as well as the design pressure point is not equal to the use of pressure. Design pressure greater than or equal to 1.5 times the nominal pressure. In industrial pipe using flange connection is very extensive. Within the family, the pipe diameter is small, but low pressure, invisible flange connection. If a boiler room or the production site, everywhere flanged pipes and equipment. Environmental analysis process stainless steel flanges in the pipeline project, stainless steel flange flange is mainly used to connect pipes. Piping is connected to a flange of a variety of installation, using the low pressure conduit may be connected to the wires of the flange, using more than 4 kg of welding pressure flange, the sealing points between the two flanges, and then secured with bolts. Different pressure flange stainless steel elbow, the use of different thickness and different bolt connecting pumps and valves and piping, the parts of the equipment, but also to make the shape of the corresponding flange. Stainless steel flanges process environments: 1, with emery cloth and wire brush to clean. 2, tungsten steel cutting edge of a large area of ??rust. 3, with a scraper and wire brush rust corner site. 4, with a file to remove welding slag projections and various failures. 5, with a clean rag, you can with a rag moistened with solvent cleaning and priming timely. 6, on a first surface to remove rust visible to all kinds of dirt, and then degreased with a solvent or cleaning agent. 7, note the toughness of the coating alloy flanges manufacturer has not expired, you can keep playing hairy old paint surface, smooth surface defects ax after class to clean, direct painting with emery cloth. |
