摘　　要：通过调研玻璃釉防腐技术用于管道系统的发展及应用现状,并对玻璃釉涂层的防腐性能和施工适应性能进行评价研究,探讨了玻璃釉防腐技术用于油田集输系统的适用性。对玻璃釉涂层的理化性能、耐蚀性能及施工适应性能的测试结果发现,玻璃釉涂层附着力优良,耐磨性好,耐蚀性能优异,特别是在高温高压酸性环境下性能优异,但是抗弯曲和抗冲击性能不佳,虽可承受正常吊装,但防腐管的运输和装卸,必须严格遵守生产厂家的操作规程,才能保证防腐层不出现破损。结合调研结果,证明玻璃釉防腐技术用于油田集输系统具有较好的适用性,特别适用于高温、高压、高磨蚀环境。Through investigating the development and application of vitreous glaze anticorrosion technology in pipeline system,and evaluating the anticorrosion performance and construction adaptability of vitreous glaze coating,the applicability of vitreous glaze anticorrosion technology during the process of gathering and transportation system of oil filed is discussed.The test results of the physical and chemical properties,corrosion resistance and construction adaptability of the vitreous glaze coating show that the vitreous glaze coating has excellent adhesion,resistance and corrosion resistance,especially in high temperature and high pressure acidic environment,but its bending resistance and impact resistance are not good.Although it can withstand normal hoisting,during transportation,loading or unloading of the anticorrosion pipe must strictly abide by the operating procedures of the manufacturer to ensure that the anticorrosion layer is not damaged.Combined with the investigation results,it is proved that the glass glaze anticorrosion technology has good applicability for oil field including gathering and transportation systems,especially for high temperature,high pressure and high abrasion environment.
