LNG处理工厂模块暖通系统密性测试工艺

HVAC System Leak Test Method of LNG Module

主要以某大型液化天然气工厂单体模块的HVAC系统密性测试为例,论述该类模块HVAC系统密性试验的工艺方法流程。从工厂单管预制后的密性测试开始,到系统安装完成后的整体气密包划分,气密测试要求。

The method of this paper is based on a LNG module project which has been finished. And for this kind of modules the HVAC system need to be tested after the installation works. This paper will discuss the test method for single duct and systems.
