The flange profile

Flange, also called ‍₽δ×flange flange disc or flange. ±♣ Flange is a shaft and ®‍shaft connected parts, u©↑✔™sed for the connection between theφ←±& pipe ends; Also useful in the equ‌♠δ≠ipment inlet and outlet flange, used fo₹←r the connection between two equ☆ ∞♦ipment, such as reducer flange. Flaσδ₹Ωnge connection or flange ∏±¶joint, refers to the flange, gasket aβ±nd bolts are connected to each other×γ as a group of assembly sealin≠ ↕​g structure of the det↑$₩αachable connection. Pipeline flaδ•®nges refer to the flanges of piping→✔∏↑ devices and the inlet and $®outlet flanges of equipment when u¶λ£sed in equipment. There are h>©$oles in the flanges and bolts ≠‍hold the two flanges together. Use gas£ βket to seal between flanges. F≥∞langes are divided into th↓φread connection (thread connection) f​™✔£lange, welding flange a ≠≤nd clamping flange. ¶≥Flanges are used in pairs, wire c∑↔•¥onnection flanges can be used for low ‍•←πpressure pipes, welding flanges can ©φbe used for more than four kilogram↓→®σs of pressure. Add sealδ€✘ing gasket between two flanges, aφ¶nd then tighten with bolt. FlεΩαanges of different pressures have d÷≈♣ifferent thicknesses and use different ♣‍∑¥bolts. Water pump and va↓γlve, in connection with th∞±φe pipeline, the local equipment, ★φ÷ also made into the corresponding fla&®×nge shape, also know₩'n as the flange connection. ¶↔Usually in the two pla ₹ ♦ne surrounding the use of bolt co≈®Ωnnection at the same time closed conne¥<<φcting parts, generally known <β§as the "flange", such as venti•™$★lation pipe connection, this kind €'±of parts can be called "flange parts"♦₽. But this connection is only Ωλ↕€a part of the equipment, s ↑uch as the connection between the₹  flange and the pump, it is not good t™♠♦o call the pump "flange pa "rts". Comparatively small, such aπ♠ελs valves, can be called "flan"<→$ge parts"

Classification of the flσ ange

1, according to chemical industry (HG) →←£standards: Solid flanges (×‌♠IF), threaded flanges (TH™$↓•), plate flat-welded₹∞£α flanges (PL), butt-welded flanges‍ε♠ with neck (WN), flat-we✘✘•®lded flanges with neck (SO), ∏"socket welded flanges (→₹€SW), butt-welded ring lε¥≠♦oose flanges (PJ/SE), •± flat-welded ring loose flanges (‍λ♦PJ/RJ), lining flange cove₹•→r (BL(S)), flange cover (BL)™∑.

2, according to the p®Ωetrochemical (SH) industry s¶<≤αtandard: threaded flange (PT), butt w‍♣™ elding flange (WN), flat welding γ×"♠flange (SO), socket welding flange φφ(SW), loose sleeve flangβεe (LJ), flange cover (not table note).εΩ✘

3, according to the ¥γ↓mechanical (JB) industry stanδ'™dards: integral flange, butt±" welding flange, plate type€₹™∑ flat welding flange, "<butt welding ring plate type lo♣$δose sleeve flange, flat welding rin§₽g plate type loose slδ€eeve flange, flanged ring plate type lo♣↓ose sleeve flange, flan☆±≈πge cover.

4, according to the nation→​al (GB) standard: integral flangeδγ, threaded flange, butt weld§®ing flange, neck flat welding &$flange, neck socket welding flange, bu★£tt welding ring neck loose sleeve flan₽¥‌ge, plate type flat wel♣∑™∏ding flange, butt welπ♥γ§ding ring plate type loose sleeve flang®‌₹e, flange cover.

The connection form

Flange connection is the two pipes, pip∑•₩e fittings or equipm←±ent, first fixed on a fl←‍♥≈ange, between the two flang¶‌γ>es, plus flange gasket, wit®‍•♣h bolts fastened together, complete'∑‌₽ the connection. Some pipe fitβ¥tings and equipment have their own ™₽flange, also belongs to the f←​lange connection. Flan♥♦γ≈ge connection is an impo​λrtant connection way in pipelin×★ >e construction. Flanged conn£↑₩•ection is easy to use and can withsε><tand greater pressure. In industrial pi€∞ping, in the home, thφ§e pipe diameter is small, ε"∑¥and the pressure is low, αδand the flange connection is invisible.Ω♠'& If you are in a boiler room or p♣Ω♠'roduction site, there are ↕≠flanged pipes and equipm♠ ≠←ent everywhere.

According to the connection mode, t'↓γπhe type of flange connect<'ion can be divided into:

Plate type plain welding flanges, p¶>lain welding flanges w✔¶ith neck, butt welding   ↓∞flanges with neck, socket w§±elding flanges, threaded​₩‌ flanges, flange cove&¥rs, butt welding ring loose flanges wi↕γth neck, butt welding ring loose flang±±es, ring groove flanges and fl¶γange covers, large diameter flat€±→ flanges, large diameter high n₽©£βeck flanges, figure eiπ←↑₹ght blind plates, butt welding ring &®loose flanges, etc.
