Erosion-corrosion problems are still remained in oil and gas pipes even with 15Cr stainless steel pipes, therefore research and development of anti- acidic and corrosive FRP pipes against hydrogen sulfide and carbon dioxide are awaited. For solving these problems and meeting the market needs, GPI (Global oil and gas Pipes Institute) Standardization Committee has set the new technology standard as Joint design standard of anti-corroding FRP high pressure pipes. The contents of this article is applicable to the API 8 round threaded joint of Tubing, Casing, Line pipes which withstands 100MPa internal pressure.
