The flange profile

Flange, also called flange flange disc or flange. Flange is a shaft and shaft conn∑ected parts, used for the connection between the pipe ends; Also us±eful in the equipment inlet and outlet flange, used foαr the connection between two equipment, such as reducer flange. Flange connec±tion or flange joint, refers to the flange, gasket and b olts are connected to each other as a group of assembly sealing structure of the ♦detachable connection. Pipeline flanges refer to the fl✔anges of piping devices and the inlet and outlet flanges of equipment when us ed 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 c≈onnection (thread connection) flange, welding flange and clamping flange. Flanges a≠re used in pairs, wire connection flanges can be used for low pressure pipes, w≥elding flanges can be used for more than four kilograms of pressure. Add sealing gaske"t between two flanges, and then tighten with bolt. Flanges of different pressures have d♥ifferent thicknesses and use different bolts. Water pump and valve, in connection with λthe pipeline, the local equipment, also made into the co∏rresponding flange shape, also known as the flange co¥nnection. Usually in the two plane surrounding the use of bo©lt connection at the same time closed connecting parts, generally® known as the "flange", such as ventilation pipe connection, this k≥ind of parts can be called "flange parts". But this connectio"n is only a part of the equipment, such as the connec↓tion 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 type

Flange connection is the two pipes, pipe fittings or equipment, first fixed on a flang♦e, between the two flanges, plus flange gasket, with bolt♥s fastened together, complete the connection. Some pipe fittings and equipment have their oαwn flange, also belongs to the flange connection. F☆lange connection is an important connection way in pipeline construction. Flan↕ged connection is easy to use and can withstand greater pressure. "In industrial piping, in the home, the pipe diamete☆r 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 equipme✘nt everywhere. 1. According to the type of connection, the flange 'connection can be divided into: Plate type plain welding fla‍nges, plain welding flanges with neck, butt welding flanges with neck, socket we₽lding flanges, threaded flanges, flange covers, butt welding ring loose flanges with neck, butt ®welding ring loose flanges, ring groove flanges and flange covers, large✔ diameter flat flanges, large diameter high neck flanges, figure eigh×t blind plates, butt welding ring loose flanges, etc. [3].→
