أنبوب مضاد للتآكل 3PE

3PE (Three-Layer Polyethylene) anti-corrosion pipe features a composite coating system consisting of an epoxy primer layer (FBE), a copolymer adhesive middle layer, and a high-density polyethylene outer layer. This multi-layer system provides superior corrosion protection, mechanical damage resistance, and cathodic disbondment resistance compared to single-layer coatings, making it the industry standard for buried oil and gas pipelines worldwide.

Our 3PE coating line applies the coating under strictly controlled conditions with online holiday detection and thickness monitoring. The coating is tested per SY/T0413 and DIN 30670 for peel strength, impact resistance, indentation resistance, and long-term cathodic disbondment performance. Service temperatures range from -40\u00b0C to +80\u00b0C, suitable for most buried pipeline environments.
