Multilayer pipe is a composite pipe built up of different layers. The aluminium core layer of multiskin allows the pipe to maintain its form when bent into shape. The internal and external PERT layers are more resistant to corrosion than their metallic counterparts. This ensures the pipe meets the most stringent requirements for drinking water systems. As a result, the multiskin pipe has the advantages of a plastic pipe while maintain the strength characteristics and shape retention of metallic pipes.
Advantages of Multilayer Pipe
Strong and flexible
The product typically consists of three distinct layers, including an inert outer plastic layer usually made of polyethylene (pe-rt ii), which protects against corrosion and mechanical damage. This encases a central aluminum layer ensuring that the pipe can be bent into position and remain in shape, which in turn encases a final plastic layer, usually made from the same or similar material to the outside layer.
Specification challenges
Multi-layer piping is corrosion-resistant, hygienic and is not liable to oxygen diffusion through the pipe wall, which minimises the risk of damage by oxygen corrosion elsewhere in the system. It has a reduced thermal expansion compared to most plastics and retains heat due to its material make-up. It delivers a system which is stronger and more durable than plastic piping, yet lighter and more flexible than metal options.
Installation benefits
Opting for multi-layer piping systems can also result in a more efficient installation process. Such systems use press-fitting and so eliminate the need for hot works on-site. The only tools needed to form a reliable, tight and durable connection are a cutter, deburrer and press tool.
Keeping an open mind
Offering the very best of plastic and metal piping, multi-layer piping systems can help tackle head-on the common challenges of material selection. With these challenges in mind, it is essential that building services engineers keep their options open to new materials, products and ways of working.

PEX-A
PEX-A is made using peroxide. Among the three types, it is the most flexible. This makes it ideal for residential water supply lines. It can expand to an immense degree when exposed to freezing water. This means it has the highest resistance to cracking in extreme temperatures.
PEX-B
PEX-B is made through the use of a moisture-cure technique. It is a bit stiffer compared to type A. It has a specific ‘coil memory’ that will make the pipes want to go back to their initial coiled state.
PEX-C
PEX-C is made through an irradiation procedure. It’s the most challenging to work with as it’s the stiffest among the three. Its stiffness makes this type most prone to kinking and cracking in freezing water.

Why Choose the Multilayer Pipe
No risk of leakage
It is designed to withstand temperatures up to 70 ºC with pressures of 10 bar with peaks up to 95 ºC. In this way, Multilayer Pipe is able to withstand extreme working conditions.
Greater tightness of the joint
Flaring the pipe with Safety full-boring fittings eliminates the potential risk of leakage in the joint even at very high temperatures and ensures a constant flow in the connection section between pipe and fitting.
Ease of installation
The coefficient of thermal expansion is low, therefore the operations of fixing the pipeline are extremely simple: an advantage for design and installation.
The making of tubing solutions for extruding multi-layer tubes is very important for constructing tubes that consist of materials with different qualities. This is a sensitively packed tube for indulging in medically complex solutions. The thermoplastics used in the making can equip the tube with multiple qualities by adding burst restraints and ductile-ness. It even increases the overall quality of the tube by making it compatible with other medical tools like stents and catheters.
How to Maintain Multilayer Pipe
Follow manufacturer guidelines for proper installation, maintenance, and repairs
Protect the plastic pipes from sudden pressure surges by installing pressure-reducing valves or water hammer arrestors
Provide adequate support for plastic pipes, especially if they are used for horizontal runs
Ensure proper tightening of connectors
Use tools designed for the material to avoid damaging the pipes or fittings
Avoid excessive force during installations or repairs
Store the plastic pipes in a cool, dry place away from direct sunlight
Consider installing a water softener in hard water areas/install water filters if water quality is a concern
Insulate pipes in areas prone to freezing
Periodically inspect the plumbing system for any signs of leaks, cracks, or damage, and address any issues promptly
Avoid harsh chemicals, solvents, or drain cleaners that can damage plastic pipes over time
Maintain a clean, debris-free area around the pipes
Regularly flush the system to remove sediment and debris.
Identify your application
Determine the purpose of the multilayer pipe, whether it's for plumbing, heating, gas distribution, or another application. Different applications may require specific types of multilayer pipes.
Consider material
Multilayer pipes are typically made of materials like pex (cross-linked polyethylene), aluminum, and hdpe (high-density polyethylene). Choose a material based on factors like temperature resistance, flexibility, and durability.
Size and diameter
Select the appropriate size and diameter of the multilayer pipe based on the flow rate, pressure requirements, and compatibility with fittings and fixtures.
Pressure rating
Ensure that the multilayer pipe you choose has the necessary pressure rating to handle the water or gas pressure in your system. Check the manufacturer's specifications for pressure ratings.
Temperature resistance
Consider the temperature range the multilayer pipe will be exposed to. Choose a pipe that can withstand the temperatures of your system without deforming or losing its properties.
Compatibility with fittings
Make sure the multilayer pipe is compatible with the fittings and connectors you plan to use. Check for standardized connections to ensure a secure and leak-free installation.
Certifications and standards
Look for multilayer pipes that meet industry standards and certifications for quality and safety, such as nsf, astm, or iso certifications.
Uv resistance
If the multilayer pipe will be exposed to sunlight or outdoor conditions, choose a pipe with uv resistance to prevent degradation over time.
Flexibility and ease of installation
Consider the flexibility of the multilayer pipe, especially if you need to navigate tight spaces or around obstacles during installation. Flexible pipes can be easier to work with.
Precautions for Using a Multilayer Pipe
1. The pressure test can be more than 30 minutes. If the site environment permits, the pressure test time can be longer.
2. The purchase of Multilayer Pipe and fittings must be guaranteed and must be operated by professionally trained technical workers.
3. According to the horizontal, horizontal and vertical principle, a deep groove larger than the diameter of the water pipe should be grooved on the basic floor of the room, and then Multilayer Pipe fittings should be laid, followed by sequential hot-melt connection. The process flow is very important.
4. After all Multilayer Pipe fittings are fused together with hot melt technology, the necessary pressure strength test is carried out.
5.The hot-melt technology is finalized after cooling. It is not that the longer the time, the better. Long-term pressure will damage the water pipe. When it is ensured that there is no leakage of water, then landfill is carried out.
How to Install The Multilayer Pipe
Preparation stage
Purchase double-layer pipes, pipe connectors, sealing materials and other required materials.clean up the site, and carry out the necessary semi-finishing and reinforcement work.Measure and mark the direction and position of the mountain pipeline according to the design drawings.
Outer pipe installation
Connect the outer pipes in turn and lay them in place according to the design requirements.Use pipe brackets or wrong firmware to fix the outer pipe firmly.Check the connection of the outer pipe to ensure tightness and firmness.
Inner pipe installation
Prefabricate the inner pipe according to the direction and length of the outer pipe. Inner pipe Insert the inner pipe into the outer pipe from one end.Adjust the position of the inner pipe and fix it with auxiliary parts such as positioning rings.
Treatment of voids between pipes
Through the grouting port, the special shrinkage grouting material is injected into the gap between the inner and outer pipes.using vibrating rods and other tools to vibrate and compact the grouting material.After the grouting material is solidified, plugging grouting.
Connection and accessory installation
Install flanges, valves and other connecting accessories according to the design requirements.Install pipe compensators where they are needed to relieve stresses caused by temperature changes.
Pressure test and inspection
Hydrostatic test is carried out on the double-layer pipeline system, the tightness and pressure bearing capacity are checked, the overall quality of the pipeline is checked, and the problems found are rectified.
Elbows: Elbows are used to modify the flow direction between two pipes, with variations available in angles of 45 and 90 degrees.
Tees: Featuring a "T" shape, tees are equipped with three openings (one inlet and two outlets) to create branch connections.
Couplings: These fittings are employed to connect pipes of the same diameter in a straight line, aiding in the repair of broken or leaking pipes.
Adapters: Adapters facilitate the connection between pipes of different types and enable the conversion of a pipe end into a male or female thread. They are commonly utilized for PVC and copper pipes.
Nipples: Nipples are fittings featuring male threads on both ends and are used to connect two female threaded pipes or fittings.
