The 950 Series® Alkathene pipe from Marley is an affordable water supply pipe made from quality latest-generation polyethylene materials and designed to handle the rigours of farm life. Easy to install and compatible with common low-density polyethylene (LDPE) fittings, its aqua-coloured stripes make it easy to spot in any Farm Source yard.
Flexibility – greater flexibility (bending radius) makes handling and installation easier.
Durability – new generation materials and strong UV resistance ensures longer life and suitability for above and below ground applications.
Bloat and trace element resistance – appropriate to use with active bloat treatments and resistant to common trace elements such as magnesium, copper and zinc making it ideal for inline water medication systems where these are used.
Compatibility - can be used as a system with popular LDPE fittings commonly available.
Recyclable – made from 100 percent recyclable materials.
Variety - available in 15, 20, 25, 32, 40 and 50 millimetre (mm) diameters and 25, 50, 100 and 200 metre (m) coils to suit a variety of farm design requirements.
The 950 series has high-level expansion allowing an extra 2mm per lineal metre of pipe with every 10 degree increase in pipe material temperature.
For above-ground installations where the pipe is not fixed and left to snake, the expansion will be taken up by the flexibility of the pipeline system.
If the system is buried, no allowance for expansion and contraction is normally required if the pipeline is permitted to return to normal operating temperature prior to final connection and backfilling.
Flow will remain constant throughout the life of the 950 series pipeline under normal circumstances. The system is resistant to most forms of chemical attack but if aggressive chemicals are to be used, consult the chemical resistance table in the Marley pressure pipelines manual - available on the Marley website.
Moving liquid in the pipe creates kinetic energy due to mass and velocity, so make sure valves are opened and closed slowly to reduce the likelihood of a pressure surge (commonly known as water hammer).
If the system is installed above ground, it is important the pipe is protected from damage by stock or vehicles. Also keep the pipe away from sharp objects where long-term abrasive action can occur due to expansion. Ensure the pipe has freedom of movement and, if secured to fences, the clipping method must allow for the pipe to move freely.
