Research and Application of Carbon-Fiber Composite Material on the Reinforcement and Repair Effect of Expansion Joints
Expansion joints,as a kind of elastic compensation element that can be freely extended and retracted,have been widely used in gas pipeline systems.However,in long-term operation,some products have cracks,stress corrosion cracking and even leakage due to material structure,working conditions,fatigue load,etc.This paper introduces in detail the field application of carbon fiber composite material reinforcement and repair technology,and verifies its repair effect and sealing performance;through the detection of universal test comparison machine,the mechanical properties of expansion joints before and after reinforcement,including deformation,tensile and compressive properties,are analyzed.The feasibility and limitations of carbon fiber composite material for expansion joint reinforcement and repair are objectively evaluated,which provides reference for the maintenance of similar gas pipeline components in the future.
