HDPE PIPE PRODUCTION
3.1 DESCRIPTION:
HDPE water pipes are being manufactured from original High Density Polyethylene and PE 100 and MRS=10MPa, meaning that pipe will tolerate the same stress 50 years after. Safety coefficient of pipes is 1.25.
The APF HDPE pipe ranges:
• Outside diameters: – 16mm to 500mm.
• Length: -up to 200m (depending upon customer request).
• Nominal pressures: – PN6 up to PN25 as per ISO standards

3.2 ADVANTAGES OF APF HDPE PIPES
• Absolutely non-toxic and completely inert.
• Maximum hydraulic quality due to its smooth inner lining
• Corrosion and abrasion resistance
• Chemical and electrolytic inert.
• Watertight networks.
• Insensitive to ground movement.
• High mechanical resistance.
• Resistance to hammer effect caused by water pressure.
• Limited fitting types due to its flexibility.
• Excellent flow characteristics.
• Exceptional durability and long life time above 50 years
• Easy for transport and handling
• Easy connection by welding or with couplings
• Very flexible and extremely resistant to vibration, seismic strikes and ground movements.
• UV resistant and resistant to temperatures from -30°C up to +60°C.
• Very low pressure losses since coefficient friction are 10 times less than with steel pipes.
3.3 APPLICATIONS
• Underground potable Water transport
• Supply connections.
• reclaimed water
• Sewerage
• Drainage
• Mining purposes.
• Irrigation projects
• Industrial usage
• Waste water disposal
• Chemical transports
3.4 Applicable Standards
APF produces HDPE pipes made according to the following standards:
• ISO 4427-2
• ISO 1183
• ISO 427
• Tolerances in accordance with ISO 11922-1:1997 grade V and grade T.
3.7 Coil Dimensions
The pipe shall be coiled such that localized deformation, e.g. buckling and kinking, is prevented.
• The minimum internal diameter of the coil shall be not less than 18dn. (It`s referring to ISO 2725)
• Coiling product diameter: – 16mm up to 110mm.
• Coiling Length: – 50m up to 200m (Depending upon customer request and APF standard as per diameter)
