The ff-therm multi Difustop pipe made of PE-Xa is extremely reliable. The special salt bath cross-linking results in a cross-linking degree of over 75 %. Special ageing stabilisers keep the pipe permanently supple and ensure high thermal resilience. The ff-therm multi Difustop PE-Xa solid plastic pipe is predominantly used for the installation of underfloor heating systems and is easy to install thanks to its flexibility.
The ff-therm multi Difustop pipe made of PE-RT is especially suited for heating applications. Its unique molecule structure provides the cross-linked PE-RT heating pipe with high resilience and it is also very fatigue-resistant and stress crack-resistant. The ff-therm multi Difustop PE-RT solid plastic pipe is predominantly used for the installation of underfloor heating systems and is easy to install thanks to its flexibility.
alpex-duo® XS / turatec multi - multilayer composite pipes
alpex-duo XS and turatec multi are multilayer composite pipes made of superior materials – the inner pipe is made of either cross-linked (PE-X) or non-cross-linked polyethylene (PE-RT) as needed, the core is made of flexible aluminium and the outer pipe is made of heat-stabilised polyethylene (PE). Top quality materials offer the perfect combination for the handling as well as absolute safety in operation. Whether used in potable water or heating systems, multilayer pipes for the alpex-duo system in sizes ranging from 16 to 32 mm in diameter are always the right choice.
alpex-duo® XS fittings - Intelligent fittings with 3 possible crimping contours
alpex-duo fittings (16, 20, 26 and 32mm) can be crimped using three different crimping contours (F, TH and B). The crimp technology is used to install the fittings onto the pipes. It only takes four steps to complete installation according to applicable standards. Fittings provide reliable pipe connections. Base body, O-ring, fixation ring and compression sleeve fit perfectly together. In addition to all FRÄNKISCHE multilayer composite pipes, alpex-duo fittings can also be used to connect ff-therm multi PE-X Difustop plastic pipes of dimensions 16 - 20mm – for an optimised application in radiant heating systems.
A special extrusion process allows for the ff-therm ML5 Difustop pipe to be produced in a single step, whereby a special adhesive layer is used to permanently and reliably bond the inner PE-Xb and the outer PE layer to the core EVOH oxygen diffusion barrier layer. Due to the manufacturing process and thanks to their properties ff-therm ML5 Difustop pipes are highly resistant to deformation and various types of stresses. Special anti-ageing agents and stabilisers keep the pipes permanently malleable and ensure high thermal stability.
This multilayer composite pipe system, is specifically optimized for radiant heating and cooling applications, contains an extremely thin aluminium layer that meets all requirements in terms of stability. The flexible profitherm AL multilayer composite pipe can be easily used in any radiant heating installation and guarantees reliable operation. The inside and outside layers of the pipe are made of polyethylene of raised temperature resistance (PE-RT) and the inner core layer is made of butt-welded aluminium (PE-RT/AL/PE-RT). These three layers are permanently bonded together with a special adhesive – designed for highest demands, excellent reliability and extreme durability.
The various alpex F50 PROFI composite pipe designs are of utmost quality, flexible and practice-oriented, with internally cross-linked materials and a butt-welded aluminium core (PE-X/AL/PE-HD) for drinking water and heating installations. A combination that ensures ideal processing and superior operational reliability. Whether as flexible coiled pipes, stable straight lengths, pre-insulated multilayer composite pipes, or pipes with protective sheathing - the installation is easy and time-saving!
