| 3LPE anti-corrosion pipe: It is a commonly used anti-corrosion pipeline, and the following is its related introduction:
Structural composition
The structure of the 3LPE anti-corrosion pipe consists of three layers. The bottom layer is epoxy powder coating, the middle layer is adhesive, and the outer layer is polyethylene layer. This structure combines the advantages of each layer of material to form a high-performance anti-corrosion system.
Performance characteristics
Good anti-corrosion performance: The outer layer of polyethylene can effectively block external corrosive media such as moisture, oxygen, salt, etc. from coming into contact with the steel pipe. The epoxy powder coating has strong adhesion to the surface of the steel pipe, providing good bottom protection. The adhesive in the middle tightly binds the three layers, enhancing the overall anti-corrosion effect and significantly extending the service life of the steel pipe.
High mechanical strength: The polyethylene layer has high hardness and toughness, and can withstand various external forces such as impact, friction, and soil pressure during transportation, installation, and use of pipelines, making it less prone to damage, cracking, and other problems.
Good temperature resistance: It can maintain stable performance within a certain temperature range and can generally adapt to environments ranging from -20 ¡æ to 80 ¡æ, meeting various usage requirements under different environmental conditions.
Strong anti cathodic peeling performance: Under cathodic protection, the coating can maintain good stability and is not easily peeled off, ensuring a tight bond between the anti-corrosion layer and the steel pipe and improving the reliability of the anti-corrosion system.
application area
3LPE anti-corrosion pipes are widely used in long-distance transportation pipelines for oil and natural gas, urban gas, water supply, heating pipelines, and other fields. |
