The pipeline industry has changed tremendously over the past 75 years. Pipeline metallurgy has become stronger and less prone to corrosion. New exotic metallurgies have been introduced to further resist the chemicals that are now often found in oil and gas streams, such as sour gas, chlorides, and steam. Pressures and temperatures have increased, and emissions reduction requirements have become a way of life for most companies. Meanwhile, the operation of a fire safe pipeline has also become a higher priority.
During that same time period, isolation gaskets have largely stayed the same. Seventy-five years ago, the isolation material was a plastic with filler. Today, the majority of isolation materials are still plastic with filler. Some have a metal core, but are still plastic with filler — known as glass-reinforced epoxy, or GRE.
How well do plastic isolation gaskets and plastic isolation gaskets with metal cores fare in today’s oil and gas pipelines? The reality is not extremely well. Key considerations include chemicals in lines, the use of steam, increased pressures and temperatures, fire safety, and emissions, and many plastic-based isolation products are not keeping up. This presentation will demonstrate many issues being seen in the field with plastic-based isolation gaskets, as well as an innovative solution.
