ISO 13844:2015 specifies a method for testing the leak tightness under negative pressure, angular deflection, and deformation of assembled joints between elastomeric-sealing-ring-type sockets made of plastic or metal and plastic pressure pipes.

UnitedTest supply UT2060 Piping System Joints Leak Tightness Tester is our company independently developed and produced the corresponding supporting equipment. This equipment is a customized product, which can be customized according to the user's testing requirements for the suitability of the elastic sealing ring joint connection in the drainage pipe system (the test project user can optional), and can be upgraded to a full-function, full-model product. Equipment for the mechanical connection seal part of the pipeline pipe fittings is very necessary, the test form is mainly by the medium pressure water pressure (several times the nominal pressure), low pressure water pressure (50KPa-5KPa or less), air pressure, low air pressure, negative pressure (-30KPa) in the form of test pipeline or pipeline connection part in the form of system sealing performance under the action of horizontal, deflection inclination, bending and other external forces. Widely used, the pipeline system for the purpose of: polyethylene PE, polypropylene PP-R, aluminum-plastic pipe, hard PVC water supply and drainage, all kinds of mining pipes, FRP pipes, rubber composite hoses, communication pipes and various buried structure wall pipes.
