Product Description

A heat-shrink sleeve for electric fusion joints is a device used for pipeline connections. It utilizes electric heating to melt polyethylene material, achieving sealing and connection of pipelines. It is widely applied in fields such as petroleum, natural gas, and thermal insulation.

1.Structural Composition
1.Outer Protective Sleeve: Typically made of polyethylene, providing mechanical protection and insulation.
2.Heating Wire: Evenly distributed inside the sleeve, generating heat when electrified.
Inner Fusion Layer: In contact with the pipeline, melts upon heating to achieve sealing.
3.Terminal Connectors: Used for connecting to the power source.

2.Working Principle
The heat-shrink sleeve is placed around the pipeline connection area. When electrified, the heating wire generates heat, causing the inner fusion layer to melt and fuse with the pipeline surface. After cooling, a strong seal is formed.

3.Main Features
1.Excellent Sealing: Melts and tightly bonds with the pipeline, preventing leaks.
2.Easy Operation: Only requires electrification for heating, no complex equipment needed.
3.Strong Adaptability: Suitable for various materials and specifications of pipelines.
4.High Durability: Resistant to corrosion and aging, with a long service life.

4.Application Fields
1.Petroleum and Natural Gas: Used for connecting and repairing transmission pipelines.
2.Thermal Insulation Engineering: Used for connecting urban heating insulation pipelines.
3.Chemical Industry: Used for connecting pipelines transporting corrosive media.
4.Power and Communication: Used for connecting cable protection pipes.

5.Installation Steps
1.Preparation: Clean the pipeline surface to ensure it is free from oil and impurities.
2.Install the Heat-shrink Sleeve: Place the sleeve around the pipeline connection area, ensuring proper alignment.
3.Connect Power: Connect the terminal connectors to the power source.
4.Heating and Fusion: Electrify to heat to the specified temperature and duration.
5.Cooling and Solidification: Allow to cool naturally after power is turned off, completing the connection.
6.Precautions
1.Power Matching: Ensure the power voltage matches the sleeve requirements.
2.Temperature Control: Avoid temperatures that are too high or too low, affecting fusion quality.
3.Environmental Conditions: Avoid operation in humid or contaminated environments.
4.Safety Protection: Wear protective gear during operation to prevent burns.
7.Summary
The heat-shrink sleeve for electric fusion joints is an efficient and reliable pipeline connection device widely used in multiple industries. Proper installation and maintenance ensure its long-term stable operation.
