CHARACTERISTICS EASY GAS

INTERNATIONAL APPROVALS
Metalic - plastic multilayer piping systems and fittings Enolgas is certificate the standard UNI/TS 11344 and ISO 17484.

MATERIALS
Multilayer pipe rolls
Standard PEX-C/ALU/ PEAD

Inner layer: Cross-linked polyethylene (PEX-C);
The inner layer of the pipes is made of cross-linked polyethylene (PEX-C), which provides the product with a good mechanical solidity and a particular outstanding thermal resistance.

The inner intermediate PEX-C layer is provided with a tape so to be integrally attached to the intermediate aluminium alloy layer. The aluminium film is adapted to the PEX-C pipe and welded longitudinally. Aluminium alloy films with different thicknesses are used to deve- lop the various diameters: 0,40mm for diameters 32 pipes; 0,20mm for diameters 16-20-25 pipes.
The intermediate layer is an oxygen barrier and provides the EASY•GAS and EASY•WATER systems, the typical stability for metal piping.

Outer layer: Polyethylene (PEAD)
The intermediate layer is also provided with tape so as to attach it to the outher layer in polyethylene (PE), the purpose of which, is to protect the aluminium against any actions of external agents (oxygen, humidity, etc...).

Corrugated insulation cover on request.

INSTALLATION
In the EASY•GAS and EASY•WATER System jointing is obtained by axially polling the steel fastening bushing on the multilayer pipe. Before pulling the bushing, the pipe is cold-expanded by means of a special tool. After the coupling is positioned, the pipe will return to its original shape thanks to the “memory” effect. Advantages of this system are multiple because the memory effect of the PEX-C inner layer makes it possible to take advantage of its characteristics in a remarkable way and ensure an hydraulic seal (in addition to the mechanical seal) only via the pipe (without the o-ring) with a minimum reduction of its passageway section. Load losses, localized within couplings because of their shrinkage are therefore much more, limited.

THE INSTALLATION IN 5 STEPS
Below is a description of the system installation in five simple basic steps. These directions must be strictly observed to ensure a perfect installation.

Use the specific circular pipe cutter to precisely cut the EASY•GAS and EASY•WATER pipe, to avoid that jointing is only partial, the cut is to be as perpendicular to the pipe axis as possible.
Insert the steel fastening bushing onto the pipe, maintaining the marking towards the outside of the coupling.
Expand the pipe end using the expander provided with the supplì, where the corresponding head has been preinstalled. Extract the bushing previously inserted from the working area, and tighten the two handles inwards. Rotate the expander with a qarter turn, then repeat the operation.
Insert the coupling into the pipe.
Use the presser jaws to move the fastening bushing towards the coupling body. The jaws should be positioned on the one side of the joint’s coupling area and on the other side, on the backside of the bushing.
