Even though it has been established that smaller diameter pipelines are safer to operate, gas pipeline industry needs cost-effective ways to transmit larger volumes of gas over long distances at higher pressures with at least 50 years of service life. Recognizing that current gas pipelines are made primarily of steel which is subjected to corrosion and hydrogen embrittlement, the proposed project focuses on developing glass fiber reinforced polymer (GFRP) composite pipes including a range of joining systems. A few of the many advantages of GFRP composite pipes are their non-corrosiveness, magnetic transparency, and high strength-to-weight ratio. Therefore, it has been suggested herein that GFRP pipes and joints will be designed, manufactured, and evaluated under static and fatigue load responses. Emphasis will be given to evaluate stress-rupture, shear-lag, and durability of GFRP composite pipes that can sustain internal pressures ranging from 6000 to 8000 psi.119
