The Application of Hydraulic stud Tensioning Equipment at Pickering NGS
Main Article Content
Abstract
The quest for leak-tight bolted joints is about as old as mechanical engineering itself. This paper describes the use of modern, lti-head stud tensioning equipment during the ril, 1987 shutdown of Pickering N.G.S., Unit No. 8, to achieve leak-tight, channel-to-tube- sheet joints in Shutdown Cooling Heat Exchangers and Moderator Heat Exchangers. The text that follows provides an overview of the theory involved, a description of the equipment used and of the methodology followed at the Station, and concludes with the leak-tightness and manrem exposure results obtained.
