To date, standards proposed for filament-wound glass resin line pipe used by the petroleum industry generally define only mechanical tests for structural strength. It will be explained why this data alone can be very misleading as a basis for comparison. Other parameters, such as chemical resistance, actual pressure ratings, safety factors, ultraviolet sensitivity, life of plasticized liners, and long term flow stability, are felt to be far more meaningful and realistic for evaluation of the product from the user's standpoint. This paper will present a composite set of practical methods suitable for determining the basic properties of the product for the petroleum industry. Comparative actual test data will be included. In conclusion, a chart to establish practical evaluation ratings will be submitted. The use of this chart will enable the user to assess filament-wound glass-resin line pipe for his application, with a high degree of confidence.
