The Utility Model under discussion consists of a pipe which is pre-fitted with a socked end (1), serving the purpose of guaranteeing a perfect alignment of the joint with respect to the pipe (T) to which it is applied. This model is built performing adequately the pipe at one of its ends, along with creating suitable internal shape for the gaskets (3), necessary for the connection with the pipe to be jointed. |
