Anti Corrosion Steel Tube Supplier-GNEE
- Functional differences
The pipeline anti-corrosion layer is mainly used to prevent pipeline corrosion and enhance the service life and safety of the pipeline. Commonly used anti-corrosion materials include epoxy coal pitch, polyurethane, epoxy fiberglass, etc. The thickness of the anti-corrosion layer is generally above 0.5mm.
The pipe insulation layer is mainly used to prevent pipe heat transfer, save energy, and reduce pipe losses. Commonly used insulation materials include polyurethane foam, aluminum silicate wool, glass wool, etc. The thickness of the insulation layer is generally above 20mm.
- Material differences
There is a big difference in the materials used for pipeline anti-corrosion layer and insulation layer. The anti-corrosion layer mainly uses chemical materials such as epoxy resin, thermoplastics, glass flakes, etc., while the insulation layer mainly uses mineral wool, rock wool, aluminum silicate, polyurethane foam, etc. Material.
- Construction differences
The construction methods of pipeline anti-corrosion layer and insulation layer also vary. The anti-corrosion layer is constructed by spraying, brushing, etc., and sometimes it is also necessary to use a wrapped construction method. The insulation layer is constructed using winding, closed construction and other methods.
- Summary and comparison
Although pipeline anti-corrosion layers and insulation layers have different functions, they are also used together in some pipeline projects. For example, in some pipelines transported in special media such as low temperature, high temperature, corrosion, etc., both thermal insulation and anti-corrosion are often required. In this case, materials and construction methods that integrate anti-corrosion and thermal insulation are needed.
At the same time, in terms of construction management, the construction schedule, technical difficulty, coating quality, etc. of the anti-corrosion layer and insulation layer need to be strictly controlled to ensure the quality and safety of the pipeline project.
