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. Mianyang selling products of stainless steel pipe fittings, 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. S body - ferritic duplex stainless steel has approximately the same proportion of the austenite phase and ferrite phase, austenitic - ferritic duplex stainless steel of both ferritic and austenitic stainless steel mechanical properties characteristics, Zigong both high strength stainless steel pipe fittings, and good toughness and weldability, duplex steel and resistant to chloride stress corrosion, pitting corrosion resistance of stainless steel pipe fittings Sichuan for resistance to sulfuric acid, phosphoric acid and corrosion resistance as well as dilute hydrochloric acid corrosion of various chloride aqueous solution. With the development of oil and gas industry and the chemical industry, an urgent need for some of the corrosion-resistant pipe. As China's Sichuan Province in East Sichuan gas field found in world-class, but contains large amounts of natural gas H2S, CO2, SO2, Cl2 and other gases, corrosion of the steel is very serious, because the steel pipe corrosion and leakage accident occurred. Also known as flange or flange flange, tube and pipe flanges are so interconnected parts, connected to the pipe end. There are holes on the flange, so that the two flange bolts tightly connected between the flange gaskets for sealing. Stainless steel flanges mainly to ensure that tube and pipe interconnected parts. By structure type, with integral flanges, loose flanges and threaded flange. Common integral flange having welded flange and welded flange. Flange tube fittings with finger flange (flange or disk access) is. It may be cast from, but also by screwing or welding composition. Flange connection defined by a pair of flanges, a gasket and a number of bolts and nuts. Spacer placed between the two flange sealing surface, tighten the nut, gasket surface pressure over the stainless steel tube deformation reaches a certain value, and fill the sealing surface uneven, the coupling does not leak tight. Flange connection is a detachable connection. There are perforations on the flange can be worn bolts, so that the two flanges tightly connected between the flange gaskets for sealing. According to the connected components can be divided into the container flange and pipe flange. Stainless steel flange Technical parameters: Size: 1/2 "to 240" (10-6000) Class: 0.6Mpa ~ 32Mpa, 150Lb ~ 2500Lb, PN0.25-PN42.0 Material: 304,304L, 321,316,316L , 310S and other materials Ministry of Chemical Industry Standard: HG5010-52 ~ HG5028-58, HGJ44-91 ~ HGJ65-91, HG20592-2009 (PN series), HG20615-2009 (Calss series) Application: boilers, pressure vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, food and other industries. Stainless steel flange main functions: 1, connecting pipes and keep the duct sealing; 2, easy to replace certain pipeline; 3, easy to open the inspection line situation; 4, to facilitate the closure of certain pipeline. Stainless steel flange steel Category: Stainless steel is usually divided into 304, 304L, 316, 321, 316L and other categories.
