Product Description:
The PEXA/PERT prefabricated insulated plastic piping system offers
a high-performance solution by integrating advanced materials and
insulation techniques. This system utilizes service pipes made from
cross-linked polyethylene (PEX-a) or PE-RT II, ensuring durability
and reliability. Widely adopted in contemporary construction
projects and various industrial settings, it provides efficient
thermal insulation and protection.
This innovative piping system consists of three distinct layers
that work together to deliver optimal performance. The innermost
layer features service pipes crafted from either PEX-a or PE-RT II
materials, known for their excellent flexibility, chemical
resistance, and long service life.
Surrounding the service pipe is a layer of polyurethane (PU) foam
insulation. This foam insulation significantly reduces heat loss
and enhances energy efficiency, making it ideal for applications
that demand precise temperature control.
Finally, the system is enclosed within a high-density polyethylene
(HDPE) outer casing. This protective shell safeguards the internal
components against mechanical damage, environmental factors, and
corrosion, ensuring longevity and reliable operation in various
conditions.
Features:
Unlike traditional pipe-in-pipe batch foaming techniques that
manufacture pipes individually, Huashida has pioneered an
innovative continuous production system. This state-of-the-art
solution seamlessly integrates the extrusion of PU foam insulation
and the HDPE outer casing into one uninterrupted process.
This advanced production line offers significant improvements in
efficiency and sustainability. It achieves up to a 40% increase in
production capacity while reducing energy consumption by 30%.
Furthermore, the system ensures consistent, high-quality output
through the use of sophisticated automation and precise process
controls.
Fully compliant with the EN 253 standard, this groundbreaking
technology delivers exceptional economic benefits. It is
particularly suited to meet the demands of modern district heating
and cooling networks, providing a reliable and cost-effective
solution for infrastructure development.
Technical Parameters:
The following table presents detailed specifications related to the
dimensions of work tubes and shell tubes. These measurements
include the diameters of work tubes and shell tubes, as well as the
thickness of the shell tube walls.
The first column indicates the size designation combining the work
tube and shell tube diameters, separated by a slash. The second
column lists the exact diameter of the work tube in millimeters.
The third column provides the shell tube diameter along with its
corresponding wall thickness, also measured in millimeters.
| Work / Shell Tube Diameter (mm) | Work Tube Diameter (mm) | Shell Tube Diameter and Wall Thickness (mm) |
|---|
| 20/78 | 20 | 78 × 2.0 |
| 25/78 | 25 | 78 × 2.0 |
| 32/78 | 32 | 78 × 2.0 |
| 40/93 | 40 | 93 × 2.2 |
| 50/113 | 50 | 113 × 2.4 |
| 63/128 | 63 | 128 × 2.7 |
| 75/143 | 75 | 143 × 3.0 |
| 90/163 | 90 | 163 × 3.2 |
| 110/163 | 110 | 163 × 3.2 |
These dimensions are integral to ensuring the compatibility and
structural integrity of tubes used in various industrial
applications. By specifying both the diameter and the wall
thickness of the shell tube, it is possible to select materials
that meet the necessary strength and durability requirements.

Applications and Usage Scenarios
One of the primary uses is in heating and cooling pipelines, where
these pipes are perfect for district heating and cooling networks
that utilize pre-insulated pipe systems. Their design ensures
efficient thermal management and energy conservation.
In industrial settings, these pipes are well-suited for
transporting hot water, chilled water, and various process fluids.
They find extensive applications in factories, chemical processing
plants, and power generation facilities, supporting critical
operational needs.
For building plumbing purposes, these pipes are commonly employed
in both commercial and residential environments. They effectively
serve heating systems as well as water supply networks, ensuring
reliable and safe fluid distribution.
Additionally, these thick-walled pipes are ideal for installations
whether underground or overhead. Their robust construction provides
the high strength and durability required for projects that demand
long-term reliability under challenging conditions.
