Product Description Product DescriptionFlange (Flange), also called flange flange disc or flange. The flange is a part connected between the shaft and the shaft, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures. The pipe flange refers to the flange of the pipe distribution pipe in the pipe device, and the import and export flange of the equipment is used in the equipment. There are holes in the flange and bolts make the two flanges tightly connected. The flange is sealed with a gasket. Flanges are divided into threaded connection (thread connection) flanges, welded flanges and clamp flanges. Flanges are used in pairs, wire flanges can be used for low pressure pipes, and welded flanges for more than four kilograms of pressure. Put a gasket between the two flanges and fasten them with bolts. Different pressure flange thickness is different, they use different bolts. Pumps and valves, when connected with pipelines, the local parts of these equipment are also made into corresponding flange shapes, also known as flange connections. All the connecting parts that are connected by bolts around two planes and are closed at the same time are generally called "flanges", such as the connection of ventilation pipes, and this type of part can be called "flanged parts". But this connection is only a part of the equipment, such as the connection of the flange and the pump, it is not good to call the pump "flange parts". Relatively small such as valves, etc., can be called "flange parts".flange (flange) connection is the two pipes, fittings or equipment, first fixed in a flange flange, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection mode in pipeline construction. The flange connection is easy to use and can withstand greater pressure. In industrial pipes, in the home, the pipe diameter is small, and it is low pressure, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.According to the connection method, the type of flange connection can be divided into: plate flat welded flange, flat welded flange with neck, butt welded flange with neck, socket welded flange, threaded flange, flange cover, butt welded with neck ring loose flange, flat welded ring loose flange, ring groove flange and flange cover, large diameter flat flange, large diameter high neck flange, figure 8 blind plate, butt welded ring loose flange, etc. Detailed Photos Product ParametersNational standardGB/T9112-2000 (GB9113·1-2000 ~ GB9123? 4-2000)American StandardANSI B16.5 Class150, 300, 600, 900, 1500 (WN, SO, BL, TH, LJ, SW)JIS 5K, 10K, 16K, 20K (PL, SO, BL, WN, TH, SW)German standardDIN2573, 2572, 2631, 2576, 2632, 2633, 2543, 2634, 2545 (PL, SO, WN, BL, TH)Ministry of Chemical Industry standardHG5010-52 ~ HG5028-58, HGJ44-91 ~ HGJ65-91Flange standardHG20592-2009 (PN series) \HG20615-2009 (Calss series)Mechanical standardsJB81-59 ~ JB86-59, JB/T74-1994, JB/T79-94 ~ JB/T86-94Pressure vessel standardsNB/T47020-2012 ~ NB/T47027-2012, JB1157-82 ~ JB1160-82 B16.47A/B B16.39B16.48CertificationsCompany ProfileOur AdvantagesFAQQ1, are you a manufacturer or a trading factory?A: We have been a factory for more than 10 years and can provide a variety of customized products.Q2, if OEM is accepted?Answer: Welcome to custom sample.
