The flange profile
Flange, also called flange flange disc or flange. Flange is a shaft™ and shaft connected parts, used for the connection÷ between the pipe ends; Also useful in the equipment inlet and outlet flange, used for the± connection between two equipment, such as reducer flange. Flange connectiαon or flange joint, refers to the flange, gasket and bolts are ¥connected to each other as a group of assembly sealing struδcture of the detachable connection. Pipeline flanges refer to the £flanges of piping devices and the inlet and outlet flanges of equipment whe₽n used in equipment. There are holes in the flanges and bolts hold the t$wo 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 pai£rs, 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 fla§nges, and then tighten with bolt. Flanges of different pressures have different thickness®es and use different bolts. Water pump and valve, in connection with the pi'peline, the local equipment, also made into the corresponding flange s≈hape, also known as the flange connection. Usually in the two plane surrounding the use of bolt σconnection 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". ComparativΩely small, such as valves, can be called "flange parts"®
Classification of the flange
1, according to chemical industry (HG) standards: Solid flanges (IF), threaded fl€anges (TH), plate flat-welded flanges (PL), butt-welded flanges with neck (WN), flat-we→lded flanges with neck (SO), socket welded flanges (SW), butt-welded ring loosδe flanges (PJ/SE), flat-welded ring loose flanges (PJ/RJ), lining flange cover (BL(S)), flange↔ cover (BL).
2, according to the petrochemical (SH) industry standard: threaded flange (PT), butt weldλing flange (WN), flat welding flange (SO), socket welding flange (S☆W), loose sleeve flange (LJ), flange cover (not table noteφ).
3, according to the mechanical (JB) industry standards: integral fσlange, butt welding flange, plate type flat welding flange, butt weldin↕g ring plate type loose sleeve flange, flat welding ring plate t•ype loose sleeve flange, flanged ring plate type loose sleeve flange, flange cover.
4, according to the national (GB) standard: integral flange, threaded flange, butt welding flange,♣ neck flat welding flange, neck socket welding flange, butt welding ring neck loose sleeve fla♣nge, plate type flat welding flange, butt welding ring plate type loose sleeve flange, flange co ver.
The connection form
Flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, betw♥een the two flanges, plus flange gasket, with bolts fastened together, com•plete the connection. Some pipe fittings and equipment have their λown 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 pressu×re. In industrial piping, in the home, the pipe diameter is small, and the pre∑ssure is low, and the flange connection is invisible. If you are in a boiler room or production site, there are flanged pipes and equipment everyw×here.
According to the connection mode, the type of flange≥ connection can be divided into:
Plate type plain welding flanges, plain welding flanges with neck, butt welding fla∏nges with neck, socket welding flanges, threaded flanges, flange covers, bu±tt welding ring loose flanges with neck, butt welding ring loose flaεnges, ring groove flanges and flange covers, large diameter flat flanges, large dia↔meter high neck flanges, figure eight blind plates, butt welding ring loose flanges, etc.♣
