The continually-welded middle layer of aluminium pipe makes the pipe able to withstand higher pressure.

The materials have a very high resistance to ageing, if utilised at the optimum pressures and temperatures.

Long Term Hydrostatic Curve Graph

The aluminium layer controls the expansion and contraction of the pipe. The expansion/ contraction rate is relatively similar to copper pipes.

Coefficient Of Heat Expansion

The smooth surface of the inner PE layer is resistant-free to the transport water as it ensures no scale, calcium and algae or other mineral build-up which will reduce the flow or performance.

Water Flow Diagram

The cover layer of aluminium makes the pipe oxygen tight with negligible oxygen permeability and avoiding corrosion hazards due to oxygen penetration and damage as a result of exposure to UV-rays.

Oxygen-permeability Of Various kinds Of Plastic Pipes

Once the pipe has been bent, it remains in the desired position like a metal pipe. It is therefore possible to prepare lengths of pipe with the preassembled fittings in the warehouse, when a series of systems are required, and transfer them to the construction site later, ready to assemble the system. The malleable features of the pipe enable bends with a very narrow radius to be formed. A pipe bender is necessary if bends are required in a larger diameter pipes or a very narrow radius of curvature is required. Use of an anti-crushing spring is recommended when bending manually, if the radius is narrow.

Fewer joints means less cost, less work and less problems, which are always associated with leakage problem.

Light weight long coils make water services line installation simple and minimize the storage space. Pipe cuts easily with simple hand held pipe cutters.

The inner layer of PE is corrosion-free and therefore particles of rust, limestone flakes or scales deriving from galvanic corrosion will not happen. PE is especially resistant to abrasion. This property is very important, particularly at bends where the abrasive action of the impurities contained in the water increases, especially when the water flow rate is particularly high.

The thermal conductivity of P.A pipe has a value of 0.43 W/m.k. namely, very low.

P.A. Pipe is less likely to ‘sweat’ or create moisture on the outer surface of plumbing pipes than typical metallic plumbing systems.

P.A Pipe’s inner and outer layers of PE meets the requirement of USA Food and Drug Administration (FDA) regulation 21 CFR 177.1520. (Source: Supplier)

The  P.A.Pipe has very high ignition temperature thanks to the internal metal layer. The density of smoke produced is very low and the emissions are not toxic.

The sound absorbing properties of the P.A Pipe are very good. The pipe’s inner and outer PE lining absorb the noises.

Long coil make water service line installation simple and less wastage as compared to conventional fixed length pipe.
