Frustoconical Pipe Joint for Universal Connection

The patent applies universality by designing a single accessory range that can connect both cross-linked polyethylene pipes and multilayer pipes. The main body incorporates a frustoconical leak-tight joint that adapts to different pipe types through alternative assembly methods (press-fit or push-fit), eliminating the need for separate accessory ranges for different pipe types while maintaining connection reliability.

The patent reduces production and storage costs by designing a universal accessory range that serves both cross-linked polyethylene and multilayer pipes. The frustoconical leak-tight joint design allows a single accessory to accommodate different pipe types, reducing the total quantity of different accessory types that need to be manufactured and stored, while maintaining reliable connections for each pipe type.

The patent changes the geometric parameters of the joint by using a frustoconical shape instead of a cylindrical one. This frustoconical geometry allows the joint to self-adjust and compensate for pipe irregularities and out-of-roundness under low-pressure conditions (1-3 bar), preventing leakages while maintaining the simplicity and speed of push-fit assembly.

The patent enables self-service assembly where the pipe itself, through its own insertion motion, provides the necessary compression force to secure the connection. The frustoconical joint design allows the pipe to press-fit or push-fit into the accessory without requiring external mechanical compression tools, thereby maintaining connection strength while dramatically improving ease of operation and reducing assembly time.
