LNG-FSRU再气化模块高压管系气体强度试验研究

Experimental Research on Gas Strength Test of High Pressure Piping System of LNG-FSRU Regasification Module

LNG再气化模块为LNG-FSRU船型的核心装置,其高压管系的强度试验是整个装置建造的关键节点。通过液氮增压并汽化作为高压试验气源的工艺,相比传统的清水介质,不仅缩短了试验周期,减少了试验工序和专用工装的使用,降低了系统干燥所需的人工和材料费用投入,同时也降低了整个装置后期运行时的风险。

The LNG regasification module is the core device of a LNG-FSRU ship,and the strength test of the high-pressure piping system is a key node in the construction of the entire device.The process of pressurizing and vaporizing liquid nitrogen as a high-pressure test gas source not only shortens the test period,but also reduces the use of test procedures and special tooling,and the labor and material costs required for system drying compared to traditional clean water media.Meanwhile,it also reduces the risk of the later operation of the entire device.
