Paper: Update On API Activities For Fiberglass Pipe And Downhole Tubing And Casing

More and more interest is generated for fiberglass tubulars because of their excellent corrosion resistance and mechanical strength. The major obstacle for more extensive use of fiberglass has been the lack of recognized engineering standards that would allow the field engineer to specify fiberglass with confidence for a particular application. Recognizing this need, several API committees are at work with unusual speed and efficiency to develop product specifications for fiberglass tubulars. Specifications for low-pressure line pipe were issued in 1986. Specifications for high-pressure line pipe followed in 1988. A specification for fiberglass downhole tubing is expected to be issued next year, in 1991. Finally, a specification for fiberglass casing is planned to be issued in 1992. This paper summarizes these API activities and details API fiberglass product specifications, both those issued and those still in committee.
