爆破片和爆破板

Bursting Discs


A bursting disc is a non-reclosing device that is designed to burst or rupture at a predetermined pressure, thus relieving a dangerous build up of pressure or vacuum. Bursting discs protect plant, pipework or vessels from unacceptable levels of pressure or vacuum.

提供多种压力排放和防爆设备。爆破板在不断增加的应用领域内提供安全的、瞬时的压力排放。

Marston 爆破片能够在危险的压力或真空度下保护装置、管线和容器，爆破板则能在粉尘和气体爆破时提供低压保护。

爆破片基本上是一种非重闭型压力排放装置，通常由金属、石墨或塑料制成，能够在一个预定压力下爆破，从而在危险的压力货真空度夏保护装置、管线和容器。
