What are the main types of plastic pipe joints?
1, simple expansion joints, the hoop with the gland ring, can only be used in vertical pipe.2, nut gland type expansion joint, can be used for riser and cross tube.3, pressure type expansion joint (for the upper pipe of the project, expansion joint is easy to leak and seal, pressure system drainage).
Force transfer joint: it is a new product connected with pipe and pump and valve. Connect them by bolts to make them a whole and have a certain amount of displacement. This can be adjusted according to field size during installation and maintenance, and axial thrust can be transmitted to the whole pipe at work. This will not only improve efficiency, pumps and valves also play a certain role in the protection.
Limit expansion joint spacing device is arranged in the basis of the original performance of telescopic joint, double locking nut in the maximum expansion capacity, in order to achieve the pipeline in the expansion amount allowed in free expansion, a quantity exceeding the maximum expansion capacity, can play a role of limiting, can effectively ensure the safe operation of pipeline the utility model is especially suitable for vibration or have a certain inclination and the connection in the corner in the pipeline.
Telescopic joint connection: suitable for conveying water, oil, gas and particulate medium squirrel like piping, reliable sealing performance, easy handling, can compensate the pipeline within a certain range of displacement, displacement and deflection and thermal expansion and vibration absorption pipeline.
