Qingdao Huashida Machinery Co., Ltd. manufactures and develops heat shrink sleeve production line equipment that produces environmentally friendly, non-polluting, and harmless anti-corrosion products for pipe connections.
Application Scenarios:
1. Anti-corrosion of welded joints of buried and overhead steel pipelines
2. Insulation repair for insulated pipelines
3. Can also be used for sealing and anti-corrosion at pipe flange connections
Product Structure:
Composed of two layers of materials:
1. Base material: Radiation cross-linked polyolefin
2. Adhesive layer: Special sealing hot-melt adhesive
3. Two-component solid epoxy powder
Working Principle: After heating, the base material shrinks radially, and the inner adhesive layer melts, firmly bonding the steel pipe and epoxy coating, and tightly wrapping the repair area to form a whole. The adhesive strength to the primed steel is greater than 70N. Whether for wrapping elbows or straight pipe connections, the surface is smooth and wrinkle-free after heating, and the bonding strength meets national standards.
Performance Characteristics: Excellent wear resistance, corrosion resistance, impact resistance, and good UV resistance and light aging resistance.
Product Classification: According to the on-site construction environment, 3PE heat shrink tape is divided into open type and closed type, with supporting products including EVA adhesive strips, fixing pieces, repair patches, and solvent-free epoxy primer. Cooperation Cases:
Chinese Projects: Tangshan Xingbang Jilin 8476-meter gas project 3PE anti-corrosion pipe engineering, Sinopec Sichuan 7132-meter polyurethane pre-insulated direct-buried pipe gas field project
International Projects: Vietnam Ho Chi Minh City cooling project 5602 meters, Africa Uganda oil transportation project 50000 meters, etc.
Applicable Pipe Ranges:
1. Petrochemical anti-corrosion
2. Heating network
3. Steel pipe anti-corrosion
4. Long-distance oil and natural gas steel pipe weld anti-corrosion
5. Urban gas pipeline joint anti-corrosion
6. Heating steel pipe joint anti-corrosion
7. Water pipe joint anti-corrosion
Summary of Product Advantages and Features:
1. High mechanical strength and strong anti-aging ability;
2. Good resistance to environmental stress;
3. Excellent bonding performance;
4. Easy to use;
5. Standards: SY/T 23257-2017, NACE RP0303-2003;
6. Applicable external anti-corrosion coatings: PE, FBE, PP, recommended rust removal grade: Sa 2.5;
7. Product specifications can be used for all steel pipes from DN100 to DN3000;
8. Base material thickness from 1.0-2.0mm, adhesive layer thickness from 0.2-2.5, multiple models available for various construction needs.
