自1995年开始,我所对温州市液化石油气市政管道进行了试监检,自1996年7月1日劳动部颁发了《压力管道安全管理与监察规定》并开始实施以后,我所对本市压力管道正式实施监督检验,其中量大面广的当属液化石油地下市政管道和小区庭院管道。现已监检液化石油气地下市政管道和小区庭院管道约120km。在监检过程中我们发现,由于安装单位取证时间短,质保体系运转、安装质量时常发生一些问题,以下就几起较典型的质量问题谈点想法。
Since 1995, I conducted a pilot inspection of Wenzhou LPG municipal pipelines. Since July 1, 1996, the Ministry of Labor issued the Regulations on Safety Management and Supervision of Pressure Pipelines and started implementing it, The formal implementation of the pressure pipeline supervision and inspection, which is undoubtedly the majority of liquefied petroleum underground municipal pipelines and residential courtyard pipeline. The liquefied petroleum gas (LPG) underground municipal pipeline and residential courtyard pipeline have been inspected for about 120km. During the inspection, we found that due to the short time of forensics of the installation unit, the quality assurance system is in operation and the quality of the installation often has some problems. Here are a few more typical quality problems.
