TWIN PUF pipes
Twin PUF pipes represent the combination of several pipes into one protective sheaths, galvanized (ground networks) or polyethylene (underground heat supply mains), depending on application. Installation of supply and return pipes as a single large pipe is a fairly new trend in routing heat supply systems. The grouping of cold water supply pipes with hot water supply pipes into one protective sheaths prevents pipes from freezing in winter and reduces heat loss of the transported medium. The property of maintaining the temperatures of transported media is particularly important for the regions of the Far North.
The inclusion of several pipes into one sheaths allows creating pipelines of various types and for different applications, and combining heat supply systems with water supply lines. The twin pipe design represents a complete set of two small diameter pipes. All pipes are combined with the polyurethane foam insulation, as well as a polyethylene or galvanized protective layer. The choice of the outer sheaths depends on the planned installation location. The inclusion of several pipes allows reducing the space for routing the pipeline, which is especially important when installing communications in development areas. Space saving has a positive effect on construction costs and labor costs.
The main advantages of multi-pipe insulation:
- Low heat losses;
- Wide range of permissible operating temperatures;
- Service life of more than 30 years;
- Resistance to mechanical damages;
- Ease of installation;
- Light weight that simplifies the assembly of structures;
- Resistance to corrosion, decaying, reduced cost of pipeline operation;
- The installed network monitoring system will accurately indicate the location of a malfunction, helps avoid the entire pipeline failure.
The twin pipe cost is a combination of the diameter of pipes in one protective sheaths, the type of insulation chosen, and the material of the working pipe. Our managers will help you choose the option that suits you in all respects.
