Multi-layer High Performance Composite (HPC) coatings are a potential solution for protecting oil/gas pipelines in extreme environments and are currently being tested in technology demonstration projects in the Arctic region. The long term performance of this protective coating is dependent upon both the coating-steel interfacial characteristics and the coating's through-thickness strength and integrity. Pre-qualification testing of HPC coatings with current standard Peel and Pull-Off tests has proven to be difficult because these tests are developed to characterize single-layer coatings.

多层高性能复合材料(HPC)涂层是一种在极端环境下保护油气管道的潜在解决方案，目前正在北极地区的技术示范项目中进行测试。这种保护涂层的长期性能取决于涂层与钢的界面特性以及涂层的穿透厚度强度和完整性。目前标准的剥离和剥离测试对高性能混凝土涂层的预鉴定测试已被证明是困难的，因为这些测试是为了表征单层涂层而开发的。
