又一句费解的， "4 off"是什么意思? to be or not to be? 再来： unless otherwise noted nozzles shall be self reinforcing type terminating in a raised face flange. 若无特殊说明，所有接管均为“自补强型”，接管终端为凸面法兰。 这么理解对否？ 我正在找self reinforcing/reinforced的意思，见到这么一段： http:///viewthread.cfm?qid=205538&page=8 i can not agree with your definition of self-reinforced. in asme viii, any nozzle greater than 2nps must be reinforced. whether the reinforcement comes from a repad, excess shell plate or excess nozzle thickness... it's a reinforced nozzle. i think the term "self reinforced" is a non-code term that most of us understand anyway. "most of us"都知道了，我还不知道呢。查看更多
