Irrigation pipes

Irrigation pipes
Irrigation and water supply pipes fall into 2 groups:

LDPE irrigation pipes
They are produced in diameters of 16 to 32 mm from LDPE (low density polyethylene) and LLDPE (linear low density polyethylene). LLDPE offers increased strength and ESCR (environmental stress cracking resistance). This allows the production of thinner pipes which are more economical for irrigation applications. They contain 2.5% carbon black and antioxidants for protection from UV radiation and heat. LDPE pipes are, generally, not recommended for water supply networks.

HDPE pressure pipes according to DIN 8074/8075 specifications
These pipes are designed mainly for water supply in irrigation systems. They are produced with selected high density polyethylene (HDPE), which is characterized by its high resistance to pressure, in diameters of 32 to 110 mm, for 4, 6 & 10 bar pressure.
 
HDPE pressure pipes are made according to DIN 8074/8075 specifications. They contain 2.5% P type carbon black, with a particle size of less than 25 nm, which guarantees the highest possible UV protection and a special combination of antioxidants for heat protection. Due to the low sulphur content (< 0,1 %) in this specific type of carbon-black, the pipes do not impart any odor to the water and are suitable for potable water networks.
