This manual satisfies the deliverables requirement for the task Training Manual for Flame Bending of Pipe, subcontracted by Ingalls Shipbuilding Inc. to puget Sound Naval Shipyard under Maritime Administration Contract MA-80-SAC- 01041. It is the project report for the second SP-7 task performed by Puget Sound Naval Shipyard in the area of flame bending. In these two projects, the Welding Engineering group at Puget Sound, with leadership from Doug Coglizer and Frank Gatto, have researched the technological basis and principles of thermal bending and straightening and applied that technology to marine piping systems. Considerable foundation material and quantitative data was developed and presented in the first project report, NSRP .No. 0297, FLAME BENDING OF PIPE FOR ALIGNMENT CONTROL. That report included not only extensive descriptions of equipment and methods of acquiring process development data, but also laboratory evaluations which show no adverse effects of calibrated and controlled thermal bending processes on Carbon Steel, coppernickel 90-10 and 70-30, and 300 series stainless steel pipes both new and previously used in sea-water systems. In this report, the Puget Sound groups primary effort has been to set forth the technology of flame bending of pipes in a format which will serve as a guide for shipyards to use in training personnel and in developing procedures specific to their own requirements.
