摘要： A plug for an opening providing an inspection X-ray source with access to pipework or to an apparatus made of a high strength steel alloy which is fragile in welding, the plug comprising an open ended cylindrical component (6) which is welded (8) to the wall of the pipework or the apparatus, and which projects therefrom, said component being made of the same steel as the pipework or the apparatus, and a second cylindrical component (9) for closing the bore through the first component. The second cylindrical component is fixed to the outer end of the first component and in line therewith by means of a butt weld (10).
