Flange is also called flange flange disc or flange.  The flange is a part version that is connected between the shaft and the shaft, and is used for the connection between the pipe ends;  The right is also useful for the flange on the inlet and outlet of the equipment, for the connection between two equipment, such as the reducer flange.  Flange connection or flange joint, refers to the flange, gasket and bolts are connected to each other as a group of assembly sealing structure of the detachable connection.  

Pipeline flanges refer to the flanges of piping devices and the inlet and outlet flanges of equipment when used in equipment.  There are holes in the flanges and bolts hold the two flanges together.  Use gasket to seal between flanges.  Flanges are divided into thread connection (thread connection) flange, welding flange and clamping flange.  Flanges are used in pairs, wire connection flanges can be used for low pressure pipes, welding flanges can be used for more than four kilograms of pressure.  Add sealing gasket between two flanges, and then tighten with bolt.  Flanges of different pressures have different thicknesses and use different bolts.  wholesale Threaded flange - GKSTEELPIPE

Water pump and valve, in connection with the pipeline, the local equipment, also made into the corresponding flange shape, also known as the flange connection.  Usually in the two plane surrounding the use of bolt connection at the same time closed connecting parts, generally known as the "flange", such as ventilation pipe connection, this kind of parts can be called "flange parts".  But this connection is only a part of the equipment, such as the connection between the flange and the pump, it is not good to call the pump "flange parts".  Comparatively small, such as valves, can be called "flange parts".

Flange connection is the two pipes, pipe fittings or equipment, first respectively fixed on a flange, between the two flanges, plus flange pad, fastening together with bolts, completed the connection.  Some pipe fittings and equipment have their own flange, also belongs to the flange connection.  Flange connection is an important connection way in pipeline construction.  Flanged connection is easy to use and can withstand greater pressure.  In industrial piping, in the home, the pipe diameter is small, and the pressure is low, and the flange connection is invisible.  If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.  

According to the connection flange connection types can be divided into: plate flat welding flange, with flat welding neck flange, butt welding neck flange, socket welding flange, threaded flange, flange cover, with neck butt welding ring flange, ring flat welding flange come loose, ring groove surface flange, flange cover, large diameter plate flange, large diameter high blind flange, butt welding neck flange, eight words ring flange, etc.  

Parts of high temperature flanges often need plane high temperature sealing. If there is no good sealant in the separate pressure area of additional sealing, affected by pressure, it will cause production inaccuracy or deformation, that is to say, there will be leakage under pressure in the separate pressure area, which requires unplanned repair.  Best suited for high temperature flat surface seals is the BCOX High Temperature Sealant, which is specially formulated to remain inert in standard steam and gas turbine and high temperature flanges applications and thus can withstand hot air, steam, water, light fuel oil and lubricants, crude oil and natural gas.  It is a single component, paste sealant, industrial use, high quality sealing mixture, suitable for smooth, flat sealing surface (butt joint) temperature and pressure requirements of high conditions.  Apply to a dry surface using a stucco knife or rubber spatula stand.  Because the sealing product will not solidify, but its consistency will change slightly, maintain flexibility and elasticity, so there is no time requirement in use, the construction can be immediately put into operation, without waiting.  If it is necessary to repair the high temperature sealing surface with scratches, it should be used in conjunction with Bocos high temperature F series repair products.
