求翻译：它能防止汽液急流突然冲击而致的变形与松动。又因构件可自由膨胀，故适用于石油减压，精馏及催化裂化主精馏塔等易堵塞而温度又很高的场合。是什么意思？

It can prevent the vapor-liquid jet sudden impact caused the deformation and loose. Because components can be free expansion, it applies to the oil decompression, easy to plug the distillation and catalytic cracking main distillation column with a temperature high occasions.

It can prevent a sudden shock vapor liquid trickles down the distortion and loose. And because components can be free to expand, the pressure for oil refining and catalytic cracking the residue, such as the easy-to-plug and temperature are very high.

It can prevent the steam fluid jet stream suddenly attacks the distortion which sends with to become less crowded.And further because the component may the free expansion, but therefore is suitable for the petroleum reduced pressure, the selective evaporation and the catalytic cracking host rectifyi

It can prevent sudden shocks caused by deformation of vapor-liquid Jet and loose. Because components can be freely expanded, it applies to oil pressure, distillation and catalytic cracking the main Plug and the temperature is very high, such as in distillation columns.
