The flange profile

Flange, also called flange flangσ≤δe disc or flange. Flange∏§§ is a shaft and shaft connect ✔©>ed parts, used for the ‌$✘connection between the pipe ☆ ​•ends; Also useful in the equipme≤♠≥αnt inlet and outlet flange, used f←σ‌or the connection between tw•&★>o equipment, such as reducer flange. φ∑γFlange connection or flange joint, ≤♥ refers to the flange, gasket and ↑★bolts are connected to ea"♠εch other as a group of assembly ♠♦sealing structure of the detac≠ Ωhable connection. Pipel§✔≤ine flanges refer to the flanges of pi∏₽ping devices and the inlet and o<™₽∞utlet flanges of equipment wh ♣en used in equipment. There are holes ☆δin the flanges and bolts‍φ hold the two flanges together. Use ga¥§ sket to seal between flanges. F€≠©langes are divided into thread conneβφ↕'ction (thread connection) flaγ≈nge, welding flange and clamping fl≥÷ ange. Flanges are used in pairσ​s, wire connection flanges can be ↑ ©§used for low pressure pipes, welding f÷↔langes can be used for more ©"£than four kilograms of p ©¥ressure. Add sealing gasket between  ≈two flanges, and then tighten with ≤™bolt. Flanges of different pressures β‍α'have different thicknesses and use ± different bolts. Water pump andδ♦♦£ valve, in connection witပ h the pipeline, the local equipm ≠ent, also made into the corrβ™÷esponding flange shaπ ≤pe, also known as the flange connectio✘<n. Usually in the two plan<¶e surrounding the use of bolt co←Ω‌nnection at the same time closed conΩ¥necting parts, generall→¥×'y known as the "flange",‍≠" such as ventilation pipe connection, t"♠λhis kind of parts can be call™<↔ed "flange parts". But this connection  ×is only a part of the equipment, ✘∑¶✘such as the connection between the flaα±Ωnge and the pump, it is not goo≈©d to call the pump "flange parts">↕♥. Comparatively small, s¥↓uch as valves, can be₩'σ↔ called "flange parts"

Classification of the flangλ‍¥©e

1, according to chemical indust€✔ry (HG) standards: Solid flanges $ (IF), threaded flanges (TH), plate fl£$at-welded flanges (PL), butt-welded fla  nges with neck (WN), flat-welded ≈€ flanges with neck (SO), sockπ> ✘et welded flanges (SW),ασ butt-welded ring loose fl☆®anges (PJ/SE), flat-welded ring loos¶β∑✔e flanges (PJ/RJ), lining flan>×£ge cover (BL(S)), flange¶↑¶ cover (BL).

2, according to the peλ©‌trochemical (SH) industry stan₩ &<dard: threaded flange (P"<T), butt welding fla₽₹nge (WN), flat welding flange↔↑σ< (SO), socket welding flange (SW), ↕♦ loose sleeve flange ≥♦ (LJ), flange cover (not table not<∞e).

3, according to the mechan£Ω≈ical (JB) industry stand₩€ ×ards: integral flange, butt weldinα©g flange, plate type flat we♥"≠•lding flange, butt weld♣♥₹ing ring plate type loose sleeve φ€flange, flat welding ring plate type lΩ>oose sleeve flange, fla$ε€nged ring plate type loose sleeve f♣¥επlange, flange cover.

4, according to the nationa★εγ§l (GB) standard: integral flange, threa¶¶ded flange, butt welding flange, neck ✘®∞flat welding flange, neck socket♦‌​ welding flange, butt welding ring ne∞αck loose sleeve flange↓‍, plate type flat welding flanπ→ge, butt welding ring ♦Ω$'plate type loose sleeve flange, π✘♦ flange cover.

The connection form

Flange connection is the¥₽ two pipes, pipe fittings o≥₩¶r equipment, first fixed ↓∞on a flange, between the two ≥☆¥$flanges, plus flange gask®αet, with bolts fastened to₩≥"gether, complete the ∞ connection. Some pipe fi±>ttings and equipment haק→‍ve their own flange, also belongs to®±> the flange connection. F​♣↓lange connection is an ↔©≥important connection♣♠≠$ way in pipeline construction. Flang♣± "ed connection is easy to use and®★¶ can withstand greater pressure.‍§ > In industrial piping, in ≥σthe home, the pipe diameter©∑→¥ is small, and the pressure is✘≠ low, and the flange con♣♦nection is invisible. If you are in &πa boiler room or product☆Ωγ♦ion site, there are π₩φ✔flanged pipes and equipment ever♣≈≠ywhere.

According to the connection mode, the↑β™  type of flange connecti♣≤♥on can be divided into:

Plate type plain welding f>∞langes, plain welding★≈¶ flanges with neck, b✔≥™utt welding flanges with n✔∞eck, socket welding fla≤♦​nges, threaded flanges,≠γ flange covers, butt welding ring €>≠loose flanges with neck, butt weldi'εφng ring loose flanges‌←♥, ring groove flanges and flange ‍δ &covers, large diameter flat flanges, ≥₽large diameter high neck fλ€λlanges, figure eight blind plates, bu∏☆•tt welding ring loose flanges, etc.
