Corrosion Behavior and Internal Pressure Capacity of a Composite System Used to Connect Metallic Pipes

Abstract

This research aims over how different kinds of fiber-reinforced plastic (FRP) may change the internal pressure capacity and corrosion behavior of linked metal pipes. Hence, aluminum pipes have been fabricated for further usage in wrapping with various FRP and welding. Used FRP materials include carbon fiber/epoxy (CFRP) and kevlar fiber/epoxy (KFRP) (CFRP). These fibers have been slit into narrow strips for use in the fabric-winding technique of connecting. Four-layer KFRP pipes and eight-layer KFRP-CFRP pipes are also viable options that have been investigated. On the other hand, comparisons have been made using pipes that have two different kinds of welding. The findings demonstrated an increase in the internal pressure capacity of the pipe compared to welding. The corrosion test was finally performed. The findings demonstrated that FRP connecting methods outperformed both welded and unjoined pipes in terms of corrosion resistance. These findings indicate that FRP composites have a bright future for use in pipe joining.
