HDPE sheet joint used for patching insulated pipelines is a product designed specifically for patching buried insulated pipelines. It is composed of radiation cross-linked polyolefin substrate and special sealing hot melt adhesive, which can form good adhesion with polyolefin substrate, steel pipe surface, and solid epoxy coating.
The characteristics of HDPE sheet joint are as follows:
1. It has excellent wear resistance, corrosion resistance, impact resistance, as well as good UV and photo aging resistance.
2. Suitable for various pipeline applications that require insulation, such as centralized heating, refrigeration, oil and gas pipelines, as well as industries such as petroleum, chemical, power, construction, metallurgy, etc.
3. It should be noted that when using heat shrink tape for insulation pipeline patching, it is necessary to follow the prescribed operating procedures to ensure the quality and safety of the patching area. If quality issues or improper use are found at the joint repair due to thermal shrinkage, timely treatment and repair should be carried out to ensure the normal operation and service life of the pipeline.
Performance characteristics:
HDPE sheet joint is mainly used for pipeline joint and valve sealing. The product has the characters of good adhesive connection performance, acid and alkali corrosion resistance, fast shrinkage and sealing performance, wide application range, simple installation, fast and labor-saving, and low preheating temperature (50 degrees Celsius).
Application:
During construction, the heat shrink tape is wrapped around the treated pipeline by machine or hand, ensuring that the overlap width is not less than 30mm. The heat shrink tape is evenly heated, and the hot melt adhesive is melted at the same time. During construction, the heat shrink tape is wrapped around the treated pipeline by machine or hand, ensuring that the overlap width is not less than 30mm. The heat shrink tape is evenly heated, and the hot melt adhesive is melted at the same time. The heat shrink band is wrapped around the pipeline, forming a solid and continuous anti-corrosion layer outside the pipeline. It can resist various corrosion behaviors such as soil stress, static water pressure, cathodic stripping, chemical corrosion, and mold erosion, providing long-term and effective protection for steel pipelines.
