The flanged water finger is actually a fire-figh♦≥ting appliance. So, do you know what the f∑★→→lange is? It is actually a disc-shaped part, w✘™>∑hich is more common in pipelin≠‍←‌e engineering, and the flanges ™​are used in pairs. M​→φultistage pumps In pipeline e→&♣αngineering, pipeline pump flanges are pr♦≤‌imarily used for pipe con≥φnections. In the pipelines that need t¥☆ ©o be connected, a variety of flanges are in™↓↑stalled. The low-pressure pipelines can use w÷↔ ire-bonded flanges, and the welding flaλ∑σ​nges are used at pressuΩ↓res above 4 kg. A sealingδ‌© point is added between the t‌↔&wo flanges and then ₹δ≤fastened with bolts. Different£$✔ pressure flanges have diffe$$rent thicknesses and use different bolt$♣s. Gear oil pump pum✘ "ps and valves, when connected to the $εσ∞pipeline, the parts of these e®πquipment are also made into the corresp‌→onding flange shape,÷ε also known as flange connection. Connecti♦£©¶on parts that are closed at the s✘♦↓ame time by bolting on both ™λplanes are generally referreφ ∏↔d to as "flanges". For example, th↑•‍↔e connection of ventilat∏‍★ion ducts may be referred to as &quo§×'t;flange parts". Howe§€•↔ver, this connection is only aφ≠≥ part of the equipment, such asπ  the connection between the flange and the wa®♠σ¥ter pump, it is not good ≈‌‌‌to call the pump "flange parts"βδ♦€. Oil drum pumps are relat&"​ively small, such as valves, and c→'an be called "flange part™δ¥λs." This is an in↕×troduction to the flange.β&< Through this article we can also see t✘£hat fire-fighting appliances and pumps ™β∞"are inseparable, so they must be used togeth πer!
