Externally pressurized expansion joint 外压膨胀节
Summarize 概述
Externally pressurised expansion joints are the perfect solutions when the expansion joints must absorb very large axial movements under high pressure. In principle, there are no limits to the size of axial movement that can be absorbed by this type of expansion joint.
当膨胀节必须承受高压下很大的轴向运动时，外部加压膨胀节是理想的解决方案。原则上，这种膨胀节的轴向移动尺寸没有限制。
As the convolutions of externally pressurised expansion joints are well protected under a cover, transport damage to the convolutions is unlikely to occur but most importantly, the cover offers maximum protection against leaking bellows or bellows failure.
由于外压膨胀节的波纹管有外罩保护，运输中不太可能发生碰撞损坏，但重要的是，外罩可很大程度的防止波纹管泄漏或失效。
