anticorrosive tape
Type:Auxiliary materials
Features:Heat expansion, wear resistance; Excellent aging resistance, sealing and insulation.
Release DATE:2021-06-22
Polyethylene (PE) anticorrosive tape is mainly used in oil and natural gas transmission; Anti-corrosion of the outer surface of buried steel pipelines for water supply and drainage and gas transportation in chemical industry and urban construction. It has the characteristics of convenient construction, no pollution and so on, and is one of the preferred anti-corrosion systems for pipeline. Excellent aging resistance, sealing and insulation.
Product type: anticorrosive tape
Main properties: Heat expansion, wear resistance; Excellent aging resistance, sealing and insulation.
Scope of application: It is suitable for anticorrosion of buried long distance pipeline and anticorrosion repair of old pipeline.
Detailed introduction:
Polyethylene anticorrosive tape is made of polyethylene sheet plus a layer of rubber modified asphalt bonding, has good impact strength and tensile strength, heat expansion, wear resistance characteristics. It is suitable for anticorrosion of buried long distance transmission pipelines and anticorrosion repair of old pipelines.
Polyethylene (PE) anticorrosive tape is mainly used in oil and natural gas transmission; Anti-corrosion of the outer surface of buried steel pipelines for water supply and drainage and gas transportation in chemical industry and urban construction. It has the characteristics of convenient construction, no pollution and so on, and is one of the preferred anti-corrosion systems for pipeline. Excellent aging resistance, sealing and insulation.
The product has the following characteristics:
1. Uniform thickness of adhesive layer, good bonding and sealing performance.
2, the bonding force of the substrate and the adhesive layer is large, and there is no degumming phenomenon in the process of storage or construction.
3, good heat aging, strong uv resistance.
4. High tensile strength, appropriate elongation at break, convenient for construction.
Usage:
(1) remove rust, weld, burr, oil, dirt and dry. Manual derusting should reach St3 level, and mechanical derusting should meet Sa2 level in SYJ 40707-86.
(2) Primer (manual or mechanical)
(3) The primer can be wrapped when the surface is dry, and the wrapping shall meet the requirements of anticorrosive layer grade and structure.
(4) The electric spark inspection can be qualified under the trench filling.
