PEX fitting

PEX fittings

“PEX fitting” is  “installation assembly”. PEX fittings are components of the pipeline, they are required to attach parts of it to others. These components are installed in places of transition pipes, such as PEX tubing, on the other diameter, when the direction of pipes, bends and turns of.

PEX fittings and metal pipe, usually have a thread like on the inside and on the outside. In places where the line enters the house and carried out at home, at the terminal branches of the pipeline Metal PEX fittings more in demand. They provide tight connections and ease of installation.

It should be noted that the metal-reinforced pipes and tubes, although similar to each other, because it consists of five layers, require different methods of installation.

Choosing the PEX fitting depends on its target destination. Thus, they are divided into corners, designed to change the direction of the line; bochata and couplings that connect the different parts of the pipeline; sleeves that connect pipe; plugs plugs, as well as tees and crosses, which are applied at the bifurcation of the pipeline.

Today, Metal PEX fittings are of great practical use, since the pipeline is composed of parts. Furthermore, PEX fittings znachitelno simplify laying of pipelines, the level of complexity which is very high.

PEX Pipe Plumbing

PEX Pipe Plumbing consists of several, or rather of the five (!) Layers: the internal (PEX) and external (PE) layers, the aluminum layer between them and connecting the layers of glue. Despite its multi-layer, pipe Plumbing are flexible, while retaining its shape. Coefficient of linear thermal expansion of pipe Plumbing is comparable to the coefficient of expansion of copper pipe.

To produce PEX  fitting Plumbing applied polymer new generation – Polyphenylsulphone (PPSU). This material has high impact and heat resistance, experts compare it with metal. But unlike metal Polyphenylsulphone absolutely not subject to corrosion.

The cost of metal pipes FUTURE K -1, depending on the diameter range from 1,9 to 8,4 Euro per meter.

Based on the data in the table, we can say that at 90 ° C and metal-tube pipe cross-linked PEX are more resistant to high pressures.
