Application of new anti-corrosion materials and processes, environmental policies accelerate industry greening
- Application of New Anti-corrosion Materials and Technologies
- Three-layer PE (Polyethylene) Anti-corrosion Layer Combining the anti-corrosion performance of epoxy powder with the mechanical protection of polyethylene, the service life is expected to exceed 40 years, widely used in long-distance oil and gas pipelines.
- Liquid Polyurethane Anti-corrosion Coating Solvent-free, easy to apply, strong resistance to cathodic disbondment, suitable for repair, patching, and restoration of old anti-corrosion layers, with low cost and significant environmental advantages.
- Inorganic Non-metallic Anti-corrosion Layer Such as ceramic coatings, glass coatings, etc., featuring high temperature resistance, wear resistance, and corrosion resistance, with a service life several times longer than organic materials, but currently still in the early stages of domestic application.
- Environmental Policies Accelerate Industry Greening
- Stricter Control of VOCs Emissions The country has strengthened the control of volatile organic compound emissions, promoting the transformation of the anti-corrosion pipeline industry towards green manufacturing. For example, Hubei Hansu Pipe Industry reduces organic gas emissions through activated carbon filtration technology, achieving both environmental protection and quality improvement.
- Improvement of Green Production Standards The Ministry of Housing and Urban-Rural Development issued the "Technical Standard for Industrial Equipment and Pipeline Anti-corrosion Engineering" (GB/T50726-2023), standardizing the construction and acceptance process of anti-corrosion engineering and promoting standardized industry development.
