发明名称 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 Attachable and detachable joints for use in pipe systems carrying pressured fluids are made using thermoplastics, preferably polyolefin, and provided with an integrally formed male spigot end and a female socket end. The joints are constructed using a push-fit principle. A sealing ring is inserted into the sealing groove of the female socket making the joint leak proof. Plastic or metal clamps are provided to sustain the longitudinal forces imposed on the joint exerted by the pressured fluid. The male spigot is provided with an integrally formed collar that serves as the holding surface to clamp resisting longitudinal forces.
