Abstract

A polymer lined pipe (PLP) assembly comprises two PLP sections, each having an outer metal pipe 20 and a fitted inner polymer liner 22. Each liner 22 terminates before the ends of the outer metal pipes 20, with the final portion of each liner 22 having a smooth female inner bore 28 with an original internal diameter D2. A connector 10 has a cylindrical central section between opposing cylindrical ends, and a smooth male outer shaft 14 with an original external diameter of D1, where D1 > D2. The outer male shaft 14 mates by interference fit with the female inner bores 28 to form a continuation of the liner 22 along the PLP assembly.The smooth mating of the female inner bores 28 and the male outer shafts 14 can be carried out without inducing any stress concentrations or weak points. Adhesive can be used between the male shaft 28 and female bore 14. It is preferred that (D1-D2)/2 is in the range 0.2-1mm, but can be between 0.3-0.7mm or 0.45-0.55mm. The length L of the interference fit can be greater than 50mm, and is preferred to be in the range 70-200mm, or 100-150mm.
