The PEXA/PERT prefabricated insulated plastic piping system represents a high-performance solution designed to meet the demands of modern construction and industrial applications. This system integrates advanced materials to deliver durability, efficiency, and reliability.
At its core, the piping system utilizes service pipes made from either cross-linked polyethylene (PEX-a) or PE-RT II, both known for their excellent thermal and mechanical properties. These inner pipes ensure the efficient transportation of fluids under various conditions.
Surrounding the service pipe is a layer of polyurethane (PU) foam insulation. This insulation plays a crucial role in minimizing heat loss or gain, thereby improving energy efficiency and maintaining the desired temperature of the transported media.
To protect the internal components and provide structural integrity, the system is encased in an outer protective layer made from high-density polyethylene (HDPE). This robust casing shields the pipe from external impacts, moisture, and environmental factors.
Features:
Unlike the traditional pipe-in-pipe batch foaming techniques, where pipes are manufactured individually, Huashida has introduced an innovative next-generation continuous production system. This advanced solution seamlessly integrates PU foam insulation with an HDPE outer casing through a co-extrusion process, all executed continuously in a single production line.
This cutting-edge system achieves remarkable improvements, offering up to 40% greater production efficiency and reducing energy consumption by 30%. Additionally, it guarantees consistent high-quality output, thanks to sophisticated automation and precise process control mechanisms.
Fully compliant with the EN 253 standard, this groundbreaking technology presents significant economic benefits tailored for modern district heating and cooling infrastructures, setting a new benchmark in the industry.
The table below presents the dimensions of various tubes used in shell and work applications. It provides three key measurements: the work or shell tube diameter, the work tube diameter, and the shell tube diameter along with its wall thickness.
Each row corresponds to a specific tube size. The work and shell tube diameters are specified in millimeters, while the shell tube diameter and wall thickness are given in the format diameter multiplied by wall thickness.
| Work / Shell Tube Diameter (mm) | Work Tube Diameter (mm) | Shell Tube Diameter and Wall Thickness (mm) |
|---|---|---|
| 20 / 78 | 20 | 78 x 2.0 |
| 25 / 78 | 25 | 78 x 2.0 |
| 32 / 78 | 32 | 78 x 2.0 |
| 40 / 93 | 40 | 93 x 2.2 |
| 50 / 113 | 50 | 113 x 2.4 |
| 63 / 128 | 63 | 128 x 2.7 |
| 75 / 143 | 75 | 143 x 3.0 |
| 90 / 163 | 90 | 163 x 3.2 |
| 110 / 163 | 110 | 163 x 3.2 |
These measurements are essential for selecting the appropriate tube sizes for specific technical requirements, ensuring compatibility and structural integrity in various engineering and industrial applications.
These pipes are perfect for heating and cooling pipeline systems, especially those used in district heating and cooling networks that require pre-insulated pipes. Their design ensures efficient thermal management across extensive pipeline frameworks.
In industrial settings, these pipes are well-suited for transporting hot water, chilled water, and various process fluids. They find wide applications in factories, chemical processing facilities, and power generation plants where durable and reliable piping is essential.
For building plumbing, these pipes can be employed in both commercial and residential environments. They support heating systems as well as general water supply, ensuring safety and performance in everyday use.
Additionally, the thick-walled variety of these pipes is ideal for installations either underground or above ground. Their robust construction makes them especially appropriate for projects demanding high mechanical strength and dependable long-term operation.
