residual water

The thesis present some questions in GB8334 《Periodic survey and evaluation of LPG cylinders》(the edition of 1999),such as volume determination,water pressure test,determination of strain rate of residual volume and how to make residual water flow cleanly from cylinders which have passed the water pressure test,etc.

对GB8334《液化石油气钢瓶定期检验与评定》(99版)中,就容积测定、水压试验压力、容积残余变形测定、水压试验合格的钢瓶使瓶内残留水流净等问题进行了阐述,使有关技术工作者认识到检验与评定(99版)中新增检验内容的合理性和重要性。
