1. An induction weldable pipe connector for electromagnetic induction welding to a plastic pipe having a pipe end with an external diameter D1, the induction weldable pipe connector comprising at least one induction weldable pipe socket, each said induction weldable pipe socket having a longitudinal axis and including: i) a plastic solder lining having a patterned external solder lining surface, an internal solder lining surface and at least one solder lining end face, said internal solder lining surface having an internal diameter D2 wherein D1>D2 thereby requiring forced sliding insertion of the pipe end into said pipe socket for preloading same, wherein said solder lining end face is exposed, annular, and transverse to the longitudinal axis, andii) a solid metal susceptor sleeve entirely peripherally enveloping said plastic solder lining, said susceptor sleeve having an external susceptor sleeve surface, a patterned internal susceptor sleeve surface and at least one susceptor sleeve end face, said patterned internal susceptor sleeve surface being in intimate complementary interlocking contact with said patterned external solder lining surface,wherein said susceptor sleeve end face is exposed, annular, and transverse to the longitudinal axis, and said susceptor sleeve end face is overlying said solder lining end face,whereupon on inducing electromagnetic induction in said pipe socket, said susceptor sleeve absorbs electromagnetic energy for melting said solder lining for welding said pipe socket to the pipe end, wherein said preloading and interlocking cause said melted solder lining to exude along the longitudinal axis beyond said susceptor sleeve end face to form an annular plastic extrusion. 2. The connector according to claim 1 wherein said external susceptor sleeve surface is an exposed metal surface. 3. The connector according to claim 1 wherein said susceptor sleeve includes at least one radial small diameter inspection aperture through which melted solder lining exudes therethrough on said application of electromagnetic induction for providing a user indication regarding progress of electromagnetic induction welding. 4. The connector according to claim 3 wherein said at least one radial small diameter inspection aperture is adjacent said susceptor sleeve end face. 5. The connector according to claim 3 wherein said susceptor sleeve includes a series of radial disposed small diameter inspection apertures through which melted solder lining exudes therethrough on said application of electromagnetic induction for providing a user indication regarding progress of electromagnetic induction welding. 6. The connector according to claim 1 wherein said solder lining includes alternate thin rings and thick rings staggered adjacent to each other along said longitudinal pipe connector axis such that said patterned external solder lining surface appears as a series of stepped ridges in a longitudinal cross section of the pipe connector. 7. A plastic pipe distribution system including at least one induction weldable pipe connector according to claim 1. 8. A method for electromagnetic induction welding an induction weldable pipe connector to a plastic pipe, the plastic pipe having a pipe end with an external diameter D1, the induction weldable pipe connector including: i) at least one induction weldable pipe socket, each induction weldable pipe socket having a longitudinal axis and a plastic solder lining having a patterned external solder lining surface, an internal solder lining surface and at least one solder lining end face, the internal solder lining surface having an internal diameter D2 wherein D1>D2 thereby requiring forced sliding insertion of the pipe end into the pipe socket for preloading same, andii) a solid metal susceptor sleeve entirely peripherally enveloping the plastic solder lining, the susceptor sleeve having an external susceptor sleeve surface, a patterned internal susceptor sleeve surface and at least one susceptor sleeve end face, the patterned internal susceptor sleeve surface being in intimate complementary interlocking contact with the patterned external solder lining surface, wherein said solder lining end face and said susceptor sleeve end face are exposed, annular, and transverse to the longitudinal axis, and said susceptor sleeve end face is overlying said solder lining end face,the method comprising the steps of:(a) forced sliding insertion of the pipe end into the pipe socket for preloading the pipe socket; and(b) inducing electromagnetic induction in the pipe socket for heating the susceptor sleeve for melting the solder lining for welding the pipe socket to the pipe end, wherein the preloading and the interlocking cause melted solder lining to exude along the longitudinal axis beyond said susceptor sleeve end face to form an annular plastic extrusion. 9. The method according to claim 8 wherein the external susceptor sleeve surface is an exposed metal surface. 10. The method according to claim 8 wherein the susceptor sleeve includes at least one radial small diameter inspection aperture through which melted solder lining exudes therethrough on the application of electromagnetic induction for providing a user indication regarding progress of electromagnetic induction welding. 11. The method according to claim 10 wherein the at least one radial small diameter inspection aperture is adjacent the susceptor sleeve end face. 12. The method according to claim 10 wherein the susceptor sleeve includes a series of radial disposed small diameter inspection apertures through which melted solder lining exudes therethrough on the application of electromagnetic induction for providing a user indication regarding progress of electromagnetic induction welding. 13. The method according to claim 8 wherein the solder lining includes alternate thin rings and thick rings staggered adjacent to each other along the longitudinal pipe connector axis such that the patterned external solder lining surface appears as a series of stepped ridges in a longitudinal cross section of the pipe connector.
