The problem of ensuring trouble-free operation of field pipelines is becoming more and more urgent from year to year. The development of deposits in areas with difficult natural and climatic conditions (the Far North, Western Siberia) requires a new approach to improving the reliability of pipeline systems. Along with the search for new technologies in construction and operation, the use of modern composite materials in the production of pipes is a primary task. Analysis of the causes of failures of field pipelines in the permafrost zone allowed us to identify the main ones: corrosion, water hammer, loss of stability as a result of frost heaving of soils. Comparative calculations of steel and fiberglass pipelines allow us to recommend the latter as an alternative to metal pipelines, because they have better corrosion and abrasive resistance, low roughness and thermal conductivity, high ductility and manufacturability.
