Why PEX?

Pexgol Durability test


Crosslinked molecule

PEXGOL™ pipes are justifiably regarded as the “high-tech” of the pipe industry. Their enhanced properties, such as resistance to high temperatures, harsh conditions, and abrasion, as well as PEXGOL’s excellent long-term durability, have revolutionized the applications of domestic sanitation, infrastructure, industry, slurry transportation, pumping water and more.

Use of PEXGOL pipes in industrial and mining applications worldwide is constantly increasing due to the obvious advantages of PEXGOL pipes.

PEXGOL pipes have been installed in more than half a million houses and apartments buildings as well as in hotels, hospitals and office buildings worldwide. Golan Plastic pipe production processes are supervised by many international standards institutes and the company has earned the prestigious ISO-9001: 2008 certificate.

Pexgol Durability

PEXGOL PEX pipes are special plastic pipes made of cross-linked polyethylene (PEX) in a wide range of diameters and classes, with an external diameter of up to 630 mm, making 

The Golan PEX pipe is a special type of plastic pipe made up of largest available PEX pipe on the market.

These PEX pipes, registered under the PEXGOL brand name, are well-known in the local and international plastic pipe markets. In addition to their use in heating systems, radiant floor heating and hot water transportation, PEXGOL pipes are recommended for use in various industries for the transfer of corrosive liquids and slurry pipeline and for drainage pipe systems. Their durability and self-cleaning qualities make them ideal for transporting heavy liquids and chemicals.

Material and Properties 

 

PEXGOL pipes are made of high-density polyethylene resin (HDPE) with a high molecular weight (HMW). Polyethylene resin (PE) is a long chain composed of carbon atoms, with two hydrogen atoms attached to each carbon.

The cross linking process removes two hydrogen atoms and creates free connections.

The free carbons are linked across the molecules to form a three dimensional structure (PEX).

PEXGOL has gone through a high pressure and temperature chemical process, creating

connections between carbons from adjacent PE chains, making a complex 3D network of cross-linked PE molecules.

This improves the properties of ordinary polyethylene, boosting its chemical durability and flexibility. PEX pipes are designed for working pressures of up to 24 bars, withstanding temperatures up to 110°C, but they can also withstand temperature surges up to 120°C.

PEXGOL™ PEX pipes are cross-linked by two systems: 

1. PEX-a: Organic peroxides

2. PEX-c: Irradiation (electron beam)

Multilayer Pipe Advantages

• Symmetry: Round pipe ensuring perfect sealing and equal stress distribution .
• State of the art welding: Aluminum pipe formed and welded by TIG energy; no overlapping and no oxygen permeation .
• Long-term resistance: Special aluminum alloy tubes guarantee long-term temperature and pressure resistance .
• Optimal flexibility: Easy bending by hand, yet no “spring effect”. 
• Optimal use of materials: Lightweight pipe with extra metal strength.
