Abstract

A method of making a pipe joint comprises providing a mould for forming substantially half the joint split longitudinally, moulding half the joint including strengthening webs, and assembling two halves so moulded to form the finished pipe joint. Moulding the joint in two complementary halves (12) enables strengthening webs (22) to be produced within the elbow, which is difficult or impossible with the conventional injection moulding technique. Since the webs can be designed to provide the strength where necessary, the thickness of the remainder of the elbow can be reduced, leading to an overall saving in weight and material. Moreover, by careful choice of the shape and positioning of the strengthening webs, a single mould is sufficient to produce both halves of the joint. By these means, savings of over 50 % on the cost of conventionally produced joints can be made.
