| Abstract: | This paper clarifies theoretically the relation between bend stress distribution and wall thick- ness calculation about technologic allowance in GB9222. By comparing with advanced foreign standards practically, the author points out the inappropriations existing in GB9222 and suggests revising them to tally with foreign standards, which is important to improve our standards and increase efficiency by reduc- ing cost. |
