With recent advances in PE industry, PE pipes and fittings have been introduced as a good alternative for other piping materials. Due to advantages such as resistance to corrosion and chemicals, flexibility and thereby the need for less fittings, high seismic and impact strength, high hydraulic efficiency and ease of installation, PE pipes are used in most development projects.

PE 100, the third generation of high density polyethylene compare to the second (PE80) and first (PE63) generations, has a higher minimum required strength after 50 years of operation. According to ISO standards, the minimum strength expected for PE100, PE80 and PE63 is 10, 8 and 6.3 MPa, respectively.

Generally, the advantages of PE100 over previous PE types can be summarized as follows:

Higher resistance to slow crack growth
Higher resistance to rapid crack growth
Higher hydrostatic strength and reduced thickness at the same nominal pressure
Increased hydraulic diameter
Better impact strength

HDPE pipes are used in most projects such as firefighting systems, high and low-pressure water transmission, urban and industrial wastewater systems, oil transfer, natural gas network, mining slurry transfer, cable covering and telecommunication projects .

Broad rang of application of solid-wall HDPE pipes:

Gas distribution network
Water transmission and distribution
Wastewater collection and transfer
Firefighting and fire extinguishing systems
Undersea transmission lines and intake and outfall systems
Desalination industry
Power Plants
Petrochemical complexes
Mineral industries
Irrigation and agricultural industries

HDPE pipeing system advantages:

Leak-free and reliable heat fusion joining techniques
Leak-free fittings
Corrosion resistance
Good resistance to abrasion
High flexibility
Seismic and impact strength
fatigue strength
light weight
Hydraulic efficiency
- Due to smooth inner surface and low roughness and consequently low pressure drop, PE pipes show the highest hydraulic efficiency
A wide temperature range
- HDPE piping system has a reliable performance from -40 ̊C to +65 ̊C
Chemicals resistance
