The invention provides a method of joining together lengths of fiber reinforced plastics pipe and pipe fittings wherein the pipe lengths and fittings are each provided with an annular end portion adapted to be bonded to an adjacent length of such pipe. According to the invention such annular end portion is provided with a surface layer of a textile fabric, such fabric being embedded in plastics material and being releasable therefrom upon application of sufficient force. In preparation for joining said annular end portion to another length of the pipe or fitting, a force is applied to such surface layer which is sufficient to cause the same to be peeled off thereby to expose a clean surface on the annular end portion. This clean surface, having a roughness dependent upon the texture of the fabric, serves to facilitate the making of a strong bond between the surfaces which are to be joined. |
