一家专门从事气体技术和服务的跨国公司需要一个用于隔离和密封容易受到腐蚀的管道连接的解决方案。这个特定的管道负责输送氢气和氮气，因此需要符合防火安全的可靠密封。同时，连接位置的不便与安装，无论是垂直位置还是与储罐体的近距离，都具有挑战性。
在一个Flare Gas Recovery Unit（焰火气体回收单元）上，碳钢法兰与A2205双相不锈钢法兰通过螺栓连接在焰火气体管道上。由于使用了不同的金属材料，如果不使用法兰绝缘套件，就会发生电偶腐蚀。由于焰火气体管线的特性，很难准确预测管线中将会有哪些气体，它可能是炼油厂内任何蒸汽的组合。可能会有H2S、N2、苯或任何类型的碳氢化合物等强腐蚀性化学物质，这使得化学兼容性成为一个挑战。
一家跨国气体、技术和服务公司正在寻找一种针对易于腐蚀的管道连接的绝缘解决方案，该管道输送氢气和氮气。因此，所需的解决方案必须符合防火安全标准，并且能提供极其严密的密封效果。此外，该连接位于一个位置较为尴尬的地方，垂直且靠近储罐体，这增加了安装的复杂性。
A water authority situated in Texas approached GPT industries to support a large-scale project with the aim of shifting underground well water to surface water. The project which spans 79.8 […]
一家历史悠久的中游石油和天然气运营商长期面临着酚醛绝缘垫片的问题。他们找到GPT，希望获得一个解决方案，能为几个压缩站提供更长的使用寿命，这些压缩站的管道尺寸从4英寸到20英寸NPS不等。 GPT对该情况并不意外，因为酚醛绝缘垫片一直受到几种故障模式的困扰。具体包括：脆化、渗透、较差的介电值、电气桥接以及因过度拧紧而导致的开裂。
