Flange, also called flange flang☆§ e disc or flange. Flange i"★s a shaft and shaft connected →↔©parts, used for the connection bφ£‌☆etween the pipe ends≠↕€; Also useful in the equipment α™↕inlet and outlet flange, used for the ←¥♣ connection between two equφ♠ipment, such as reducer flange. Fl‌ ange connection or flange‌>♠ joint, refers to the fla↑∑nge, gasket and bolts are •♥ πconnected to each other as a gro₽♠ ∏up of assembly sealing structure€§ of the detachable connectioδ≤£n. Pipeline flanges ref§ ₽♦er to the flanges of pipiδσ↕ng devices and the inlet ‌←and outlet flanges of equipment whe®‍n used in equipment. The$¥re are holes in the f↓$♥langes and bolts hold the two flanges★ ® together. Use gasket to♥< seal between flanges. Flanges areπ£§↓ divided into thread c‌×γonnection (thread connection) flan¶‍≠ge, welding flange and cla✘₩mping flange. Flangesε↔‍ are used in pairs, wire connecti☆±on flanges can be used •→γ≤for low pressure pipes, weΩ'↓lding flanges can be use£ ∏d for more than four kilo£↑εgrams of pressure. Add sealing gaske ∏t between two flanges, and then tighten<™ with bolt. Flanges o₽•©f different pressures ∞®↑have different thicknesses and u&×" se different bolts. Wat ∑©er pump and valve, i✔‍n connection with the pipeline, t✔♣>he local equipment, also made into ‍€εthe corresponding flange shape, "÷also known as the flange>§✘β connection. Usually in the two p¥<♥₽lane surrounding the use of b÷>>$olt connection at the same time₽γ→∏ closed connecting pa​↕↔↕rts, generally known as the ©>"flange", such as ventilation pipe conn"✘​§ection, this kind of parts can b>φ♥→e called "flange parts". Bσ‌βut this connection is only¶>≈' a part of the equipment, suc<×h as the connection ↔←between the flange and the pump, it is ₩♠not good to call the pump "flang¶"₽‌e parts". Comparatively smallλ←±∞, such as valves, can be called "fla₹♣§€nge parts"
