3PE Anti-corrosion Insulation Pipe
Main word: Polyurethane Key words: Polyurethane, Pipeline, Insulation, Anti-corrosion
Product Name: Prefabricated Direct-Buried Polyurethane Insulation Pipe Foaming 3PE Anti-corrosion Insulation Pipe
Characteristic attributes: Unparalleled comprehensive anti-corrosion performance, "1+1+1>3" effect, long-lasting lifespan, extremely strong mechanical protection and impact resistance, HDPE outer layer is tough and wear-resistant, excellent resistance to soil stress and low-temperature performance, good environmental friendliness and construction adaptability, stable material without pollution, and the pipeline can undergo "anti-corrosion first, then welding" process.
Core performance advantages:
1. Unparalleled comprehensive anti-corrosion performance
· "1+1+1>3" effect: The three-layer structure combines the excellent chemical anti-corrosion property, adhesion, and anti-anode peeling of epoxy powder with the outstanding mechanical strength, anti-permeation property, and weather resistance of HDPE. The overall performance far exceeds that of single-layer or double-layer anti-corrosion.
· Long service life: The design life can typically reach 30-50 years or even longer, significantly reducing the maintenance and replacement costs throughout the pipeline's life cycle.
2. Strong mechanical protection and impact resistance
· The HDPE outer layer is tough and wear-resistant, effectively resisting various mechanical damages during construction and operation, especially suitable for non-digging crossings (such as directional drilling), rocky areas, and frozen soil areas, etc., in harsh geographical environments.
3. Excellent resistance to soil stress and low-temperature performance
· The overall structure is flexible, able to adapt to a certain degree of foundation settlement and low-temperature shrinkage, and is less prone to cracking in cold regions.
· The adhesive layer can effectively alleviate the inter-layer stress caused by temperature changes.
4. Good environmental friendliness and construction adaptability
· The material is stable and pollution-free.
· The pipeline can undergo "pre-corrosion, then welding": High-quality anti-corrosion is completed in the factory, and only the weld seams need to be treated with patching (commonly using heat shrink sleeves) on-site, ensuring the integrity of the main anti-corrosion layer and high construction efficiency.
