LNG接收站低温阀门检验程序及允许泄漏速率探讨

Cryogenic Valves Inspection Procedures and Allowable Leakage Rate of LNG Receiving Station

由于低温阀门苛刻的工作环境,对其材质、结构等具有特殊的要求,因此在出厂前要进行一系列严格的检验试验以确保质量。本文将对低温阀门压力试验的重要过程以及试验过程中的重要参数进行逐一介绍,并对不同规范中对压力试验最大允许泄漏速率进行对比。

Because of cryogenic valves harsh working environment, as well as its material, structure, has special requirements,so the strict inspection before they go out to a series of tests to ensure the quality. This article will be to cryogenic valves of pressure test process and test process of the important parameters are introduced and the different specification for pressure test maximum allowable leakage rate were compared.
