Comparison and Analysis on Technical Specifications and Standards of Pipelines with 3PE Coating's Field Coating

Through comparison and analysis on technical specifications and standards of heat shrinkable sleeve at home and abroad, differences of performance indexes are studied, including material performances, installation processes and quality inspections. It is pointed out that pipe surface preparation and primer application are important factors for heat shrinkable sleeve's installation system. Suggestions to draw up technical specifications and standards for engineering application purpose are given as well.
