1. prevent a method for hydrate blocking pipe in pipe-line, it is characterized in that, by carrying out coating process to pipe-line inwall, making inner wall surface form the hydrophobic compound coating of one deck, comprising step:

  • The first step;

    with pipe-line inner wall surface for substrate, this substrate utilizes surface micro-fabrication technology or Wicresoft'"'"'s method make the substrate with Wicresoft'"'"'s structure;

    Second step;

    apply hydrophobic compound coating on the substrate surface with Wicresoft'"'"'s structure;

    3rd step;

    the Wicresoft'"'"'s substrate being coated with hydrophobic compound coating is carried out toast or after air-dry process, obtain the hydrophobic compound surface of dried and clean.
