Flange | Welcome to Hebei million gold piping | high pressure large diameter flange excellent quality provided by Hebei billion gold piping. Flange | Welcome to Hebei billion gold piping | high pressure large diameter flange Hebei billion of superior quality Pipe Manufacturing Co., Ltd. (www.yijinguanjian.com) 2014 upgrade been newly launched edit flange connections (flange) is connected to two a pipe, fittings or equipment, each mounted on a first flange, Greenfield flange between two flanges price, plus flange gasket, bolted together to complete the connection. Some fittings and equipment have been built flange, also belongs to the flange connection. Flanged connections are important pipeline construction. Flanged easy to use, able to withstand greater pressure. In industrial piping, use a very wide flange connection. Within the family, the pipe diameter is small, but low pressure, invisible flange connection. If a boiler room or a production site flanges, pipes and equipment everywhere flange connection. 1, according to the connection flange connection types can be divided into: plate flat welding flange, with neck flat welding flanges, weld neck flange, socket welding flange, threaded flange, blind flange, with neck for welding ring loose flange, flat welding ring loose flange ring groove flange and flange covers, large diameter flat flange, large diameter high-neck flange, blind character, butt welding ring loose flange, etc. . Flange, English (Flange) or said flange, flange. The tube and pipe flanges are interconnected parts, connected to the pipe end. There are holes on the flange bolts so that the two flange abuts. Between flange sealing gasket. Flange screw connection points / wire connection flanges and welded flanges. Flange is a discoid parts, the most common projects in the pipeline, flanges need to be used in pairs. In the pipeline project, the flange is mainly used to connect pipes. In the pipeline need to be connected, and a variety of mounting a high-voltage large-diameter flange flange excellent quality, low-pressure pipe can be used silk flange, four kilograms more than the use of pressure welding flanges. Between the two flanges sealing points, and fastened with bolts. The flanges have different pressures and different thicknesses using different bolts. Pumps and valves and pipe connections in the local these facilities and equipment, but also made the corresponding flange shape, also known as the flange connection. All in two planes at the same time surrounding the use of bolted connections enclosed parts, generally known as the "flange", such as ventilation pipe connections, this type of parts can be called a "flange parts." But this is only a partial connection equipment, such as pumps and flange connections, bad water pump called "flange parts." Relatively small, such as valves, etc., can be called "flange parts." Flange based on: (1) the nature of the transmission medium, the general media, special media, media toxic, flammable and explosive media; (2) according to the parameters of the medium, working pressure, operating temperature, in the case of the medium is determined , according to the working temperature and the working pressure of the media to determine the flange nominal pressure PN. (3) According to the place of use, the connection method and the connection conditions to determine the form of the flange and the sealing surface of the tube. (4) determine the flange specifications based on the connection object.
