Yanshan County Bo Yan Pipe Co., Ltd. is located in Yanshan County Industrial Development Zone. North of Beijing and Tianjin and Beijing-Shanghai railway to the east Bohai Sea, Tianjin Port, State Road across the county superior geographical conditions, abundant local resources, for my company's development has laid a good foundation. Best-selling products, and exported to South Korea, Vietnam, Singapore, Malaysia and other countries. I used to pursue "science and technology first, gaining the upper hand, quality, customer supreme, credit first" business ideas, is willing to domestic and foreign users and sincere welcome customers to work together to create a better future. Plate flat welding flange easily obtained, create a simple, low cost, widely used; however, less rigid high pressure flange, and therefore can not be used there is supply and demand, chemical process piping systems flammable, explosive and high vacuum requirements and height , extremely hazardous situations. Sealing surface with flat-screen and projection surface. Plate flat welding flange is the most common flange, pressure has PN0.25, PN0.6, PN1.0, PN1.6, PN2.5. Welding form: welded flange plate is welded to the pipe going into the flange. Form sealing surface plate flat welding flange has a lower categories: convex surface (MFM) DN1300 ~ 3000 DN300 ~ 3000 DN400 ~ 2000 DN300 ~ 800 tongue and groove (TG) DN1300 ~ 3000 DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 800 the whole plane (FF) DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 800 Yanshan County Bo Yan Pipe Co., Ltd. is located in Yanshan County Industrial Development Zone aluminum flange advantage over other materials flange products are as follows: 1, Quality light: aluminum flange flange quality than other material to light. You can save transportation costs and processing costs. 2, the intensity is good: not as good as the mechanical properties of aluminum flange steel, but higher than its intensity, can add copper, magnesium, manganese and other alloying elements, made of aluminum alloy flange and then heat-treated to obtain high strength. 3, beautiful, suitable for all kinds of surface treatment: aluminum alloy flange and flange surface oxide film, silver-white, relatively beautiful. If after oxidation treatment, the surface oxide film is more secure, but also dyeing brushing and the like. To create a variety of colors and surface gloss. 4, corrosion resistance, good sight: aluminum and aluminum alloy flange, the country can produce a hard and dense surface oxide film, it does not produce a lot of material fall effect. 5, resistance to chemicals: aluminum flange for nitrate, acetic acid, hydrogen peroxide, the chemical does not react flange, has a very good resistance. 6, no magnetic properties: a non-magnetic aluminum flanges thereof. 7, non-toxic: aluminum welded flange itself is not toxic, it is more suitable for aluminum flange medical equipment and food processing industries. 8, low temperature: aluminum flange temperature is low, but increased strength without brittleness, so it is utopian cryogenic plant material. Alloy flanges, flanges, Bo Yan Pipe (view) provided by the Yanshan Xian Yan Bo Industry Co., Ltd. Yanshan County Bo Yan Pipe Co., Ltd.
