Polyethylene Pipes and Fittings

Technological developments enabled important developments in the plastic raw material production, as well. Developed during 1950s, PE 32 class low-density polyethylene is used in the potable water piping lines for the first time. Later, PE 63 raw material is developed and it is successfully applied in the systems not requiring high pressure. However, PE63 is used in the lines requiring pressure up to 4 bar, due to technical properties of material. Developments in raw material continued and PE 80 raw material as 2nd generation is brought into use. Thus, PE 80 raw material started to be used with high performance in potable water and natural gas grids. Developed at the beginning of 1990, 3rd generation PE 100 raw material gets to be both high performance and economic solution to the potable water and natural gas networks areas.

• 1. Generation raw materials : PE 32 (LDPE), PE 40 (LDPE), PE 63 (HDPE)
• 2. Generation raw materials : PE 80 (MDPE), PE 80 (HDPE)

TIG Pipes are used for warm and cold water systems, radiator systems, pressured air installations, transmission of cooled fluids, inner-building fresh water systems and floor heating systems. TIG Pipes are produced through a special technology combining the superior features of plastic and metal materials. While the inner and outer layers of TIG Pipes are made of polyethylene, aluminum is used for the production of the middle layer.

The name of this special pipe is derived from the special method used to produce it. Aluminum layer is twisted over the polyethylene layer (its molecule structure includes cross linked PE-Xb) and these two materials are then fixed with arc welding (Tungsten Inert Gas).

Inner and outer surfaces of TIG Pipes are formed by PE-Xb layers which are resistant to high temperatures, hygienic,, resistant to corrosion and impacts taking root of external influences, very smooth and which are preventing sedimentation, providing excellent isolation.

In addition to these, a special adhesive and method is used for fixing the inner and outer PE-Xb layers with excellent properties to the aluminum layer.

Welding Technology Used for the Aluminum Layer of Tig Pipes

The welding technique named as Tungsten Inert Gas has been considered to be a very important technological development by the plastics industry in recent years. This method includes bending the aluminum layer onto the PE-Xb, inner layer and then fixing these two layers through arc butt welding. This technology surpasses the old technologies like overlapping in terms of life time and reliability.

Properties of Aluminum Material

Middle layer of TIG Pipes is made of aluminum. After being coated on the inner PE-Xb layer, the aluminum material is then fixed to the structure through the superior technical properties of Tig welding.

Advantages Provided by Aluminum

• Thanks to the aluminum layer taking place in Tig Pipes, oxygen diffusion from the outer medium to the water inside the pipe is prevented and no oxidation is observed on the metal parts of the system, as a result.
• Thanks to the aluminum layer, Tig Pipes can be very easily buckled and they also keep the new shape formed. As a result of their ability to be buckled at 6 times of its diameter, savings in fitting consumption can be obtained.
• Thanks to the low thermal expansion coefficient of the aluminum layer, no sagging is observed at on-wall Tig Pipe applications.

Press Fittings (For Multilayer Pipes)

Tig Pipe Press Fittings are suitable for:

• hot and cold water supply systems,
• heating systems,
• industrial applications

Press Fittings can be used with Pex-Al-Pex and Pert-Al-Pert pipes.

Raw Material

Brass
Fırat uses special MS 58 Brass as rawmaterial for the production of Metal Fittings. 

Brass is preferred in production of metal fittings due to its ease of process, extended usage life, high resistance to abrasion and corrosion. Supplied in form of bars, brass rawmaterial is manufactured as per EN 12164 and EN12165 standards.

EPDM O-Ring
Perfect functioning of Fırat Metal Fittings can only be ensured by using correct O-Ring in the system.

Ethylene Propylene Diene Monomer (EPDM) is used as the most suitable rawmaterial among synthetic rubbers for O-rings used with Fırat Metal Fittings. The only gasket which is resistant to air-water oxidation, ozone cracking is the only EPDM rubber product which has permanent deformation values required for tightness between temperatures -40°C and +130°C.

Nickel Plating
Fırat Metal Fittings made of MS 58 Brass are available in nickel plating. With nickel plating, fittings have a shining and beautiful appearance and their outer surface corrosion resistance increases and it provides a longer useful life.
