[0002] The flared connection is made of forgeable cast iron or ductile iron as the main material, and consists of a liner pipe body (bushing), nuts or bolts, threaded rings or flared flanges, and a sealing rubber ring. The pipe is compressed against the sealing rubber ring by tightening the nut or flange, so that the inner surface of the pipe and the sealing rubber ring on the liner pipe body form an oblique side sealing connection for metal pipe connection. The flared structure connection method is also widely used in bellows. The R-type flared bellows adopts a corrugated design and is connected in combination with the R-type flaring, which can give the pipe a certain flexibility and scalability, and can effectively absorb the vibration and deformation caused by thermal expansion and contraction during the use of the pipeline system, protecting its stability and safety.
