PPR Fiber Composite Pipes&Fittings

As a kind of three-layer composite Pipe, Fiber/ PP composite pipe is a real improver of normal PP-R pipe. The inside and outside layers of the pipe are made of pure polypropylene random copolymer resin, which ensures the pipe is sanitary and healthy when used for water supply. The high-performance fiber/ PP composite material of mid-layer greatly improves the characteristics of such pipes as used in the hot water system. This newly-typed pipe has higher strength, higher tenacity, higher rigidity, and lower linear expansion coefficient.

Features
Three high and one low makes the pipeline safer
This means it has higher strength, higher tenacity, higher rigidity, and lower linear expansion coefficient, which really fetches up the limitations of ordinary PP-R pipe specialized in the riser, transparent, and hot water pipe.
Non-deformation pipeline, more attractive appearance
High-performance composite pipes PP-R have a three-layer structure with PP-R material in the inner and outer layers and a reinforced composite material in the middle layer. The effect of the mid-layer was performed in the reinforced pipeline and reduced the effect of the coefficient of linear expansion. The linear expansion coefficient of the high-performance composite pipe only has 1/3 of ordinary PP-R, which is close to the aluminum-plastic composite pipe. There is no noticeable "thermal expansion and contraction" during installation and use, resulting in a flatter and more aesthetically pleasing appearance.
Resist high temperature, leak explosion-proof pipe
Given the right conditions, high-performance composite pipes can be used for long periods of time at pressures below 90℃, especially for hot water pipes.
Easy to install and construct
It can be connected with ordinary PP-R heat fusion welder and heat insertion fittings, with complete fittings, convenient and reliable structure.

Advantages
● Greatly reduced linear expansion coefficient,30% of that of  PPR, which is close to that of the stable composite pipes.
● Higher strength and stability of dimension.
● The pressure resistance is greatly improved, with 25% more pressure load than PPR under the same conditions of use.
● Improved resistance to impulse under low temperatures.
● Excellent resistance to high temperature. It can be used at 90℃ for the long term.

Joining By Heat Fusion
Joining by heat fusion is suitable for the connections of thermoplastic polyolefin pipe systems. Heat fusion connection belongs to a physical process: when pipe and fitting are heated for a certain period, whose molecular chains are melted against original arrangements, they can be connected firmly under stable pressure. Then the joint pressure in the fusion zone makes the melting molecular chains cool with materials and connect again to become a new unity. Therefore, temperature, heating time, and joint pressure are three important factors in heat fusion connection. According to DVS2207/2208, heat fusion connection includes socket-fusion,electro-fusion, and butt-fusion connections, The first two are adopted for small-bore water pipe systems, It is recommended that Weixing PP-Rpipeline adopts socket-fusion connection. When the pipe diameter is less than 63mm, they are connected by a hand-held welding machine. When the pipe diameter is over 63mm, it is recommended that a welding machine with large power should be adopted.

Heat Fusion Procedures:
● The pipe must be cut perpendicularly to its axis by the special cutter.
● To prevent compromising the quality of the connection, clean the connection areas of the pipes and fittings, avoiding sand, dust, etc.
● Make sure the corresponding heating head to the dimension of the pipe is welded. Connect the welding machine and put it on the power supply. Wait until the temperature of the heating head reaches the optimal one (260±10℃) which can be indicated by a flashing green lamp.
● Use a pencil to mark the depth of fusion on the pipe. (see the table attached);
● Insert the pipe and fitting into the welding machine at the same time. Heat according to the specified time.
● After the heating time, pull out the pipe and the fitting and immediately join them together. Minor modifications can be done during connection but the twist angle should not exceed 5°.
● When the connection is over, hold the pipe and the fitting tightly and keep enough cooling time.

When the outdoor temperature is below 5℃, the heating time will be increased by more or less 50%.


Pipe Fittings
Since the fittings and accessories are the same as for the PP-R piping system, a special panel is required to strip the pipe ends before fusion welding.

Product Knowledge

How does the incorporation of fibers affect the overall performance and characteristics of the composite?
The incorporation of fibers into PPR Fiber Composite Pipes and Fittings significantly affects the overall performance and characteristics of the composite material. Here are several ways in which the addition of fibers enhances the properties of these composite pp rct piping systems:
Strength and Stiffness:
The fibers, commonly made of materials like glass or other reinforcing polymers, contribute to increased tensile strength and stiffness. This results in a composite material that can withstand higher mechanical stresses and pressures compared to traditional PPR pipes.
Impact Resistance:
The fibers improve the impact resistance of the composite material, making it more resilient to external forces, vibrations, and mechanical shocks. This is particularly beneficial in applications where pipes may be subjected to impact or physical stress.
Creep Resistance:
The incorporation of fibers enhances the creep resistance of the composite, meaning it can better withstand long-term exposure to sustained loads without deformation. This is important for maintaining the structural integrity of the piping system over time.
Flexibility and Durability:
While PPR is known for its flexibility, the addition of fibers can further enhance this characteristic. The composite material remains flexible while gaining additional strength, contributing to a durable and reliable piping system.
Thermal Expansion Control:
The fibers can help control thermal expansion and contraction of the composite material. This is valuable in applications where temperature variations are significant, as it minimizes the dimensional changes of the pipes.
Temperature Resistance:
The fibers can contribute to improved temperature resistance, allowing the composite to withstand higher temperatures without compromising its structural integrity. This makes PPR Fiber Composite Pipes suitable for hot water and industrial applications.
Reduced Friction and Wear:
The presence of fibers can reduce friction within the piping system and minimize wear over time. This is beneficial for maintaining the efficiency and longevity of the pipes, especially in applications with abrasive fluids.
Chemical Resistance:
The chemical resistance of PPR Fiber Composite Pipes is often enhanced by the addition of fibers. This makes the composite material more resilient to corrosive substances, contributing to a longer service life.
Improved Rigidity:
The fibers contribute to increased rigidity, providing additional structural support to the pipes. This is advantageous in preventing deformation under high-pressure conditions or when the pipes are buried or subjected to external loads.
Crack Resistance:
The incorporation of fibers enhances crack resistance, reducing the likelihood of crack propagation in the material. This is crucial for maintaining the integrity of the pipes and preventing leaks.
Lightweight Construction:
Despite the added strength, PPR Fiber Composite Pipes can remain relatively lightweight compared to some alternative materials. This facilitates easier handling, transportation, and installation.
Construction and Design Flexibility:
The composite material offers flexibility in design, allowing for the creation of pipes with tailored characteristics based on the specific requirements of the application.
