<p>The invention provides a protector (2), a protector element or a protector assembly for a pipe-end (1) or a joint, the protector comprising a shaped body element or elements, shaped to mate generally in surface co-operation with the joint is additionally provided with at least one elastically deformable zone (5) which is capable of being strained elastically upon or during the process of making-up of the protector on the joint, which zone is capable of being an interference fit in its elastically strained condition on the complimentary portion of the joint irrespective of any dimensional differences that may exist due to tolerances or deviations from nominal dimensions of the protector and the joint, whereby when the protector is made-up to its final position on the joint, sufficient elastic deformation is generated in the said zone due to the interference between the joint and the protector surfaces as to constitute a seal on the joint against the ingress of foreign bodies and/or corrosion promoting agents across the said zone and/or a barrier for the retention of grease or dope.</p> |
