PRODUCT INTRODUCTION
PE-Xb Pipe (Silane-Crosslinked Polyethylene) is a high-performance plastic pipe. It adopts a special chemical crosslinking
process—silane extrusion followed by hydrolysis—to form a
three-dimensional network structure, which modifies the
molecular structure of polyethylene. This process ensures the
material’s degree of crosslinking ≥ 65%, with a dominant
three-dimensional network molecular structure. As a result,
PE-Xb Pipe offers superior performance compared to ordinary
polyethylene pipes, along with excellent physicochemical
stability. It is ideal for scenarios requiring high temperature
resistance, pressure resistance, and long service life, such as
cold/hot water supply pipelines and heating pipelines.
ADVANTAGES
Outstanding Oxygen-Barrier & Corrosion-Resistant Performance： The oxygen permeability rate of PE-Xb Oxygen-Barrier Pipe is
reduced by over 90% compared to ordinary PE pipes. It addresses the oxygen barrier shortcoming of ordinary pipes at the
source, effectively blocking oxygen intrusion, preventing
oxidation and rusting of metal components in the system as well
as bacterial growth, and building a solid defense for the long-term
stable operation of the pipeline.
Excellent thermal recovery：
Excellent Thermal Recovery With the ability to restore to its
original state when heated, it reduces the difficulty of shape
adjustment during installation and improves the flexibility and
efficiency of pipeline maintenance.
Superior Heat Resistance：
The maximum operating temperature can reach 95℃, and the
short-term tolerance temperature is up to 110℃. It can handle
high-temperature working conditions with ease, preventing pipe
burst risks from the source and providing solid protection for the
safety of the water system.
Excellent Pressure-Bearing Stability：
The working pressure can reach 6bar at room temperature, and it
can even withstand high pressures such as 12.5bar and 20bar in
some scenarios. Relying on its excellent and stable pressure-bearing capacity, it ensures no deformation or leakage of the pipeline
under complex working conditions.

PRODUCT INTRODUCTION
The inner and outer layers of the PE-Xb/AL/PE-Xb Aluminum-Plastic Composite Pipe adopt an innovative silane crosslinking technology, featuring dense three-dimensional molecular crosslinking for high temperature resistance and anti-aging
properties. Its unique middle metallic aluminum layer is joined
via ultrasonic lap welding, ensuring firmness and reliability.
With a five-layer structure, the pipe provides light-blocking and
oxygen-barrier functions, guaranteeing healthier water supply.
Combining the advantages of metal pipes and pure plastic
pipes, it is easy to bend (without rebound) and convenient to
install. It is widely used in building cold/hot water supply, gas
transmission, floor heating, and other fields.
ADVANTAGES
Oxygen-Barrier, Heat-Resistant & Pressure-Resistant：
The aluminum layer completely blocks oxygen penetration; the
PE-Xb layer can withstand long-term use at temperatures up to 95 ℃; and the aluminum layer enhances compressive strength and
creep resistance.
Corrosion-Resistant, Non-Scaling & Hygienic：
The inner wall of the PE-Xb layer is smooth and inert to ions and
most chemicals in water, making it difficult to scale. It complies
with drinking water standards.
Rigid-Flexible Integration & Stable Shape Against Thermal
Expansion：
The aluminum layer is impact-resistant; the PE-Xb layer can be
cold-bent for shaping; its coefficient of linear expansion is close to
that of metal, ensuring no bulging in underfloor heating systems.
Easy Installation & Reliable Connection：
Coiled pipes are easy to transport, can be bent by hand, and the
crimp connection is efficient and reliable.

PRODUCT INTRODUCTION
U-TYPE CRIMP FITTINGS
(SUITABLE FOR PE-XB PIPES, PE-XB
OXYGEN-BARRIER PIPES & PE-XB
ALUMINUM-PLASTIC COMPOSITE PIPES)
PE-Xb U-Type Crimp Fittings are compatible with PE-Xb
aluminum-plastic pipes, with their core feature being the
**U-type crimp structure**: Specialized tools are used for
radial crimping of the connection part (including the sealing
ring), enabling tight engagement between the fitting and the
pipe to form a rigid seal. The elasticity of the sealing ring and
the ductility of brass enhance flexible adaptation under
temperature fluctuations, completely preventing leakage.
Made of brass, the fittings are corrosion-resistant and match
the pipe’s temperature resistance (-40℃ to 110℃) and
pressure resistance. No hot-melt welding is required during
installation, ensuring fast and efficient construction. It is
suitable for scenarios requiring reliable sealing and convenient
construction, such as floor heating and radiator connections.
ADVANTAGES
Better Reliability with \"Dual Sealing\"：
Dual sealing (mechanical rigid engagement + seal ring expansion) is more vibration-resistant and temperature fluctuation-tolerant than simple threaded sealing, significantly reducing the
leakage risk.
Installation Efficiency Surpassing Traditional Methods：
No hot-melt welding is required; the crimping operation can be
completed in an instant, which is more than 5 times faster than
threaded connection. Moreover, the tools are easy to use and
suitable for different construction scenarios.
Stronger Adaptability：
Targeting the multi-layer structure of PE-Xb aluminum-plastic
composite pipes, the inner wall of the fitting is pre-set with engagement grooves corresponding to the aluminum layer and plastic layer
of the pipe. During crimping, it can simultaneously embed into layers
of different materials to form \"interlayer locking,\" ensuring a more
secure connection.
