Dual wall heat-shrinkable tube

Dual wall heat-shrinkable tube

Dual wall heat-shrinkable tube is a pipe that consists of two layers of walls, usually consisting of an inner wall and an outer wall. There is usually a certain gap between these two layers of pipe walls, forming a double-layer structure. Dual wall heat-shrinkable tubes are often used in water supply and drainage systems, power communication lines, underground transmission pipelines and other fields. Double-walled pipes have a wide range of applications in the engineering and construction fields, and can meet the special requirements of pipes in different fields.

Functional features of dual wall heat-shrinkable tube include:

1. Insulation protection: The double-wall structure can provide better insulation performance and is suitable for occasions that require additional insulation protection.

2. Strength and durability: Due to the double-walled structure, double-walled pipes usually have higher strength and durability and are able to withstand greater pressure and load.

3. Anti-corrosion: The outer pipe wall can provide additional anti-corrosion protection and prolong the service life of the pipeline.

4. Wide range of applications: double-walled pipes are often used in water supply and drainage systems, power communication lines, underground transmission pipelines and other fields.

The process of fabricating double-walled pipes usually includes the following steps:

1. Material preparation: Choose the right material, usually plastic or composite.

2. Inner and outer wall extrusion: Through the extrusion process, the inner pipe wall and the outer pipe wall are extruded at the same time.

3. Forming: After the inner and outer walls are extruded, the two layers of pipe walls are combined into a double-wall structure through molding equipment.

4. Cooling and dressing: Cooling and dressing the double-walled tube after forming to ensure that the size and surface quality meet the requirements.

5. Testing and packaging: quality inspection of double-walled pipes, packaging and storage after qualification.

This is a general manufacturing process that may vary depending on the material, process, and type of product.
