Durothene High Density Polyethylene pressure pipes are specified with confidence in the following applications:

Civil Engineering: water and sewer reticulation systems

Building: house connections and cold water reticulation systems

Agricultural: irrigation and water supply schemes and suction lines

Industrial: sewer effluent control and water purification as well as in the conveyance of most chemicals and the conveyance of potable water

Mining: used extensively in both surface and underground operations and slurries

Marine/Aquaculture: supply lines and floats

Trenchless: rehabilitation of existing pipelines.

HDPE is generally used for high pressure applications ranging from 4 to 25 BAR, in conjunction with various fittings (see next page). Durothene HDPE piping conforms to the SANS ISO 4427 specification.

TEMPERATURE - PRESSURE DERATING

CHEMICAL RESISTANCE

CODES OF PRACTICE

HDPE pipe is not recommended in applications where the fluid temperature exceeds 60ºC

Durothene HDPE pipes are resistant to a wide range of chemicals and industrial solvents. Please refer to DPI Plastics Technical Department for detailed information.

The rated working pressure of an HDPE pipe is determined at 20ºC. Where the operating temperature of the fluid in the pipe exceeds 20ºC, the pressure rating of the pipe has to be de-rated in order to maintain the designed safety factors of the pipe.

HANDLING: Pipes manufactured in HDPE are strong, durable and easy to handle. In common with most construction materials, they should nevertheless be handled with care to avoid causing damage.

STORAGE: Pipes should be stored on level flat ground, free of stones or sharp protrusions. The height of the stacked pipe should not exceed 5 coils. Normal exposure to direct sunlight during the contract will not harm the pipe.

CUTTING: Carefully cut the pipe ends square using a fine-toothed hand saw. Remove burrs and cutting debris.

JOINTING: For compression fittings: Follow manufacturer’s instructions. Note: Overtightening may cause the assembly to leak.

Buttweld and electrofusion fittings: Have a separate set of jointing instructions. Ensure that you obtain and follow the specific information when you purchase them.
