| Abstract: | In this paper, some regulations on the field joint coatings technology of pipeline outer anti-corrosion layer in GB/T 51241-2017 standard and ISO 21809-3:2016 standard are compaired and analyzed , such as the classification and material of the field joint coatings, the construction and performance index of the field joint coatings. Compared with the national standard GB/T 51241-2017, more detailed classification for the types of field joint coatings were listed in ISO 21809-3:2016 standard. The design temperature is relatively more meticulous for the heat-shrinkable materials in ISO 21809-3:2016, but the thickness of heat-shrinkable materials and the performance requirements of raw materials are more specific in GB/T 51241-2017. The requirements about surface treatment for heat-shrinkable materials are basically same in the two standards. In terms of the construction environment and the amount of overlap of heat-shrinkable materials on the pipeline, the requirements are more stricter in GB/T 51241-2017. ISO 21809-3:2016 adds performance indicators such as indentation resistance and lap shear strength to the performance indexes of anti-corrosive coating of heat shrinkable materials. The requirements of cathodic disbondment resistance indicators of heat shrinkable material are basically the same in two standards. |
