Abstract


The questions of many pipeline corrode, stress fatigue crack and welded joint flaw and so on already day by day prominent with operation of pipeline many years. but the traditional repair technology frequently needs to use fire, to produce pressure of pipeline or provides the large-scale repair equipment, not only time-consuming hard sledding but also affects the pipeline normal transportation and the safe operation. Uses the compound repair material to carry on repairing has the simplicity of operator, the construction security, the repairing intensity higher merit compares with the former repairing technology.The pape has developed the repair special-purpose normal temperature solidification resin system and levels the putty through to study the compound repair material resin system, the match of resin and textile fiber, the special-purpose equipment of repairing technology, the appraisal of repairing effect .The characteristic has the technology capability and the mechanical properties, and the resin and the textile fiber match is good. The mechanical properties, the electricity performance, satisfies with the steel products bonding properties of compound materials meets the needs. the repair increases the pressure special-purpose work equipment has been designed to provide the safeguard in order to reduce the defects effectively and control the textile fiber content and enhances the stability of repair quality . repair material and the repair technology reliability and the serviceability has been proven through the experiment .It has lay the solid foundation for promoted use of this technology.
