CROSS-LINKING METHODS – PEXB SILANE METHOD
Cross-linked polyethylene can be made using a variety of technologies recognised by international standards and distinguished by the methods A (peroxides), B (silanes), C (radiation), and D (azocompounds); the method used is indicated along with the abbreviation for the material, resulting in PE-Xa, PE-Xb, PE-Xc, and PE-Xd. Rhinox multilayer pipes are cross-linked by allowing steam to enter sealed chambers containing the product at 100° C. To ensure that the steam entering the chamber thoroughly penetrates every single coil and achieves a uniform amount of cross-linking regardless ofthe pipe’s diameter and length, a certain level of vacuum is created in the chambers
LONG LIFE
If the pipe is used according to the specified working pressure and temperature, it will have a guaranteed working life of at least 50 years.
RESISTANT TO TEMPERATURE AND PRESSURE
The working temperature can be up to 95°C, and the maximum working pressure 10 bar.
RESISTANCE TO ABRASION
Rhinox Wepit has a high resistance to abrasion, even with water containing high levels of impurities and high-speed flow
MINIMUM LINEAR EXPANSION
The aluminium layer in the Rhinox pipe means that it has a coefficient of expansion comparable to that of copper and 8 times less than an ordinary plastic
pipe. Its coefficient of expansion is 0.025 mm/mK.
OXYGEN AND LIGHT BARRIER
The aluminium layer blocks the passage of oxygen, water vapour and any other gas, therefore avoiding the formation of corrosion in the circuits. Aluminium is also a fully-effective barrier against UV radiation.
CORROSION RESISTANCE
The polyethylene internal and external layers and the fittings provided with a dielectric barrier protect the aluminium against any type of chemical, electromagnetic and natural corrosion.
HYGIENIC AND NON TOXICOLOGICALY
Rhinox-wepit multilayered pipes have been tested at a number of laboratories throughout the world and are approved for tap water distribution, i.e. the pipes release neither taste, odour nor unhealthy substances regardless of water quality.
CHEMICAL RESISTANCE
The Rhinox-wepit multilayered pipe has a very high resistance to chemicals. Building materials such as concrete, mortar, plaster, etc. do not affect the pipes negatively. Tape, paint or sealing compounds containing softening agent must not be used directly on the pipe.
LOW LOAD LOSSES
The internal polyethylene surface has a surface finish that can ensure significant reductions in load losses compared to classic metal pipes; furthermore, the absence of lime deposits or other scaling ensures a flow rate that remains constant over time.
TECHNICAL FEATURES OF
RHINOX-WEPIT SYSTEM
TIME AND MONEY SAVING INSTALLATIONS
Thanks to their excellent mechanical characteristics the Wepit multilayer pipes can be bent instead of employing fittings thus obtaining significant advantages from an economical point of view.
FIRE RESISTANCE
The installation of a system must always be performed in compliance with local and national standards and regulations, observing any fire protection provisions in force that may vary from one country to another.
LEGIONELLA AND TREATMENTS
Compared to metal pipes, Wepit multilayer pipes have a greater resistance to chemical compounds and may undergo treatments (eg. superchlorination shock) for several years without being damaged.
ACCESSORIES
A wide range of accessories and special components complete the system in order to meet all system requirements.
Modular manifolds with and without interception valves, coplanar manifolds, manifolds with shut-off valves, in-wall ball valves, fixing plates for sanitary appliances and many other items…
ALUMINIUM
There are different methods for the production of multilayer pipes and they differ mainly in the technology used in forming the aluminium pipe. It can be formed by overlapping, overlapping and welding, or by butt connection and welding.
Chosen by Wepit in that it guarantees a uniform thickness across the entire circumference, greater resistance to pressure and bending, uniform mechanical characteristics, greater adhesion values with the bonding layers and a total barrier to oxygen.
LASER WELDING ALUMINIUM
One of our outstanding innovation is the over lapped. laser welded multilayer pipe. Ultimate precision and strength for optimum quality.
