PEXAPIPE System Details

PEXc and Multilayer Pipes

PEXc pipe in conduit in sizes in stock at all times for plumbing and primary connections. Pipe in conduit for plumbing and radiator heating. All pipes are with EVOH oxygen barrier.

Multilayer pipe made of PEX, aluminium PEX. The aluminium layer is an oxygen barrier and provides rigidity in surface mounted installations.
Uniquely, the aluminium layer in this pipe is welded to give seamlessly welded pipes while in many others the aluminium layer is folded and hence less reliable when pipe is bent.

Quality Pipe for any Application

Pexapipe systems are made of high quality components. The PEXc pipe is of the same basic material as the mains pipe used by the utilities for years. But its plastic material is cross-linked for extra strength and protected from oxygen diffusion with a barrier when used in heating systems. Add to such quality the resistance to corrosion and scaling and you have low maintenance and cost plumbing. Best of all, the PEX pipe, which is available in all popular sizes and approved to many EC standards, is comparable in cost of equivalent metal pipes.


Only few companies in Europe produce the very best PEXc pipe due to the high investment in electron beam cyclotron.

IPPEC's PEXc pipe is cross linked using an electron beam generated by a cyclotron. This gives homogenous cross linking compared to PEXa which is a chemical cross linking process. PEXc needs to be cross linked to 68% compared to PEXa which is cross linked to 75% to obtain the same strength. For this reason PEXc is very strong while remaining more flexible compared with any other PEX material.

The Barrier to Corrosion

The Oxygen Pump
Plastic is not permeable to liquids but is slightly permeable to gases. Water absorbs more oxygen from the air at high temperature. This rich with oxygen water deposits its oxygen on metal parts when cooling. The process repeats itself with every heating and cooling cycle. Thus metal parts corrode easily in hot water in plastic pipes. Therefore all IPPEC PEXc pipes have oxygen barrier and can thus be connected to boilers cylinders and pumps directly. There is no need for heat exchangers, such as thermal stores, or special and expensive bronze pumps.

Main Features of Advanced PEX Plumbing

Plumbing in a ring to give better pressure distribution and water flow.

  • Flexible PEX avoids hidden joints.
  • Pipe in conduit (self-ducted pipe) in several sizes 
  • Central Manifold with Isolating Valves.
  • Wide range of compatible brass fittings.

Flexible, Light to carry and fast to to install., no joints, self ducted, durable, quick to fit, quite, clean. No corrosion or scaling.

Rigid, heavy, many joints, finite life, difficult to install, needs special skill, noisy, risk of fire, dirty to work with.

PEXAPIPE and Floor Ducts

Embedding metal pipes in floors is a very expensive business. The floor ducting required is expensive and laborious to construct. Avoiding these ducts may not be an option such as in ‘open design’ buildings. Continuous PEX pipe in conduit (pipe in pipe) solves this problem and frees restriction on designers.
The PEXc pipe remains uncut, and hence immune from leaking at a joint, when buried in floor. Therfore PEX pipe is the only solution to lay long length of pipes in floors.
IPPEC was the first to supply a complete project dossier for the heating and plumbing system.  This individual design service has proved to be invaluable and is part of our commitment to train installers in the UK.   It is an 'up front investment' in problem-free installation. Pexapipe plumbing pipe and fittings are illustrated and eplained on the drawings supplied.
