The structure of Aquatechnik’s multi-layered composite pipe is comprised of five layers of tightly bound material, allowing the pipe to be light, flexible and resistant to corrosion.

Both the inner and outer layers are made from cross-linked Polyethylene (PE-Xb), a polymer with high resistance to high temperatures and pressures. The central layer is comprised of longitudinally butt-welded aluminium pipe, which provides a barrier to oxygen and light while allowing installation flexibility and mechanical strength. Finally, two layers of adhesive bind the intermediate aluminium pipe to the inner and outer layers of Polyethylene.

This robust composition ensures our MLCP has the durability to withstand pressures of 10 bar and temperatures up to 95°C over a 50-year life cycle.

The weight of multi-layer pipe is considerably less than that of metal, allowing easy on-site transportation. At the same time, its increased flexibility provides various installation advantages and reduces the fittings needed for a system.

Multi-layer pipe is used for a wide range of applications across multiple sectors, including commercial and industrial for its corrosion resistance alone. The robust composition of Aquatecnik’s MLCP ensures the system has the durability to withstand pressures of 10 bar and temperatures up to 95°C over a 50-year life cycle.

Compression fittings for multi-layer pipes

Initially viewed as a light solution for domestic installations, compression fittings today are used in a vast range of projects.

Compression fittings work with three main components: one is a piece that holds the pipe, the second is an O-ring(s) that create a hermetic sealing and finally, a holding mechanism that keeps everything together. Like press fittings, no hot works permit is required for installation. The benefits are even more specific to:

• A significant reduction in installation times. Compression technology was designed to optimise time and make the installers’ job easier in several points.
• Limited equipment is required. Unlike press fittings, compression fittings do not require extra equipment for installation. Once the cutting, measuring, and flaring of the pipes has been completed, the actual jointing requires a few seconds. They do not require pressing machines or great strength to install.
• Easy to disassemble. Another key advantage is that the fitting can be disassembled easily in case of a mistake during an installation or removal. This is almost always impossible with press fittings or traditional methods.
• Perfect for working in cramped spaces. When space is limited, there is a risk that a joint may not be installed safely if the installer cannot access the pipes properly to use the crimping tool, A factor that could significantly influence the quality of the joint.
