Aim at the shortage in actual application that the frp pipe flange joint with the steel pipe and steel parts, in consideration of the special advantage of the adhesive boned joint, put forward the method that the steel flange adhesive boned steel pipe or steel part after the steel flange instead the frp pipe flange, or the frp pipe adhesive boned direct with the steel and steel part, it can reduce the stress concentration problem that cause from the different of the descend speed and the hot bulge or freeze coefficient in the applied process. thus reduce the damage number and the maintenance costs of the piping, so this method can have the greatly actual application value
針對玻璃鋼管道與鋼管及鋼管件之間法蘭連接方式在實際應用中的不足之處，考慮到膠接連接的獨特優勢，提出如用鋼法蘭代替玻璃鋼法蘭與玻璃鋼管道膠接后，再與配套的鋼管及鋼管件進行連接，或玻璃鋼管道直接與鋼管（件）進行膠接連接，則可減少玻璃鋼管道在應用過程中與鋼管（件）連接后因沉降速度及凍脹系數均不同而產生的應力集中問題，減少管道的損壞次數及維護成本，有很大的實際應用價值。 -
