A pipe with integral male and female ends, a joint made using the same pipe, and processes of making the pipe and the joint

摘要

The invention describes easily attachable and detachable joints for use in pipe systems carrying pressured fluids. The pipes used for the purpose are made using thermoplastics, preferably polyolefin and provided with integrally formed male spigot end (1) and a female socket end (2). The invention also discloses a method of forming tubes along with their male spigot (1) and the female sockets (2). Joints made using the pipes provided with integral male (1) and female ends (2) are constructed using a push-fit principle. A sealing ring (10) is inserted in the sealing groove (3) of the female socket (2), making the joint leak proof. Plastic or metal clamps (6) are provided to sustain the longitudinal forces imposed on the joint exerted by the pressured fluid. The male spigot (1) is provided with an integrally formed collar (4) that serves as the holding surface to clamp resisting longitudinal forces. The joint is simple in its construction, easy to assemble in field, robust and cost effective.
