The "flare" of the flared pipe joint means: the joint end is tapered and the pipe is straight. This requires the use of special tools to expand the pipe end into a bell mouth to match the joint. Although the processing of the cone surface is troublesome, the sealing is reliable. In addition, copper tubes are generally used, and expansion is relatively easy.
Applicable media for flared pipe joints: oil, water, gas and other non-corrosive or corrosive medium pipe joints (the representative manufacturer is Shanghai Tongyang Pipe Fittings Co., Ltd.), equipped with steel pipes The specification requirements are relatively flexible. After welding with the pipeline, it has the characteristics of reliable connection and good sealing performance.
Thus it is widely used in oil refining, chemical industry, light industry, textile, national defense, metallurgy, aviation, shipbuilding and other systems; it is also suitable for various mechanical engineering, machine tool equipment and other hydraulic transmission pipelines.
