Why Multilayer Composite Pipe Is the Plumber’s Choice

Multilayer pipe is a term that most people in the building services industry are familiar with. But how does it stack up against conventional plumbing materials? Why should we think about abandoning tried-and-true techniques? The answers to these questions will be discussed throughout this text.

What is a Multilayer Pipe, and how does it work?

A multilayer pipe is a composite pipe made up of multiple layers. The multi skin pipe’s aluminium core layer helps it hold its shape when bent into shape. The PERT layers on the backflow testing melbourne and outside are more corrosion resistant than their metallic counterparts. This assures that the pipe meets the most demanding drinking water system regulations. As a result, the multiskin pipe combines the benefits of a plastic pipe with the strength and shape preservation of a metallic pipe.

What are the primary advantages of this method over traditional piping?

LESSO Steel-Plastic Pipe advantages are its small weight, flexibility, and corrosion resistance. Because of its lightweight, huge coils of multitasking pipe may be readily carried to the job site. As indicated above, the pipe is commonly delivered in coils of up to 100 metres. Also, because it has a lower scrap value than copper, there is fewer security risks when it arrives on site.

Its adaptability is a significant plus when it comes to installation. The pipe can be easily bent into shape by hand, significantly reducing the number of fittings required. The interior aluminium layer keeps the shape and prevents thermal memory, which is a problem with other synthetic pipes.

Because of the corrosion resistance of the PERT coating, it can be utilised on both potable and sealed heating systems. Because there would be no pipe corrosion, the pipework’s life should be significantly extended. Blockages in components like HIUs should be more minor of an issue. As a result, on systems with HIUs, we recommend using multitasking pipes.

Other advantages include better insulating properties as compared to metallic pipes. Due to more refined surfaces and fewer fittings, they are also quieter and have reduced pressure dips.


Using multilayer composite pipe systems, such as those manufactured by Pipelife Radopress, you can combine the favourable material features of polyethene with the properties of aluminium to ensure the best possible level of safety and cleanliness for your hot and cold water supply systems.


Radopress multilayer pipes are hygienically tested for drinking water and have good abrasion and tear resistance capabilities. Multilayer Radopress pipes are appropriate for the distribution of sanitary drinking water since they are not subject to corrosion, deposit, or chemical degradation. All Radopress pipes are entirely rinsed out after manufacture to ensure product quality and hygiene.


The inbuilt aluminium layer that acts as an oxygen barrier is the main advantage of Pipelife Multilayer Composite Pipes. This contributes to the pipe’s incredible resistance to temperature variations, pressure stroke loading, torsion, and tension. When utilised in hot water systems, the aluminium barrier protects the boiler/water heater from corrosion by keeping oxidants out of the water, extending the system’s lifespan even further.

The use of LESSO Steel-Plastic Pipe in applications such as heating, hot water, and potable water has grown in popularity. An inner and outer layer of cross-linked polyethene (PEX) is sandwiched between two layers of aluminium in MLCP. The strength of the metal pipe is combined with the installation flexibility and corrosion resistance of plastic in this design.

Connections’ strength

MLCP can be combined with press connection technology to reduce installation time. Using a press connection procedure not only saves time but also assures a long-lasting and robust seal with just one press.

Despite the benefits of MLCP, when low-quality press connections are used, one of the most common causes of failure is a damaged O-ring within the fitting.

Choose the appropriate material.

Because not every MLCP is made to the same level, it is critical to choose a high-quality product. It’s also crucial to select a pipe with the proper flexibility. The pipe may buckle rather than bend if it cannot achieve the appropriate angle when the pipe is formed.

Another factor to consider when selecting a product to transport drinking water is its fit for the job. Any item used to carry potable water must have been tested and certified to ensure that the water is not contaminated. The versatility of MLCP is one of its main features. The pipe can be bent precisely with handheld tools without buckling, and it can be utilised straight off the coil. This is especially useful in projects with many corners and long corridors. The installation can be accomplished considerably faster by bending the pipe rather than cutting it.
