Sprinkler irrigation pipes withstand 6 atm pressure but all elements of the system may not work under this pressure. For example, the number of sprinklers used or the sprinkle flow rate can damage the sprinkler operation under this pressure. As such, sprinkler irrigation systems should be operated at 2-3 bar levels.
Polyethylenes defined with petrochemical development are classified according to their density LDPE/Low Density Polyethylene, MDPE/Medium Density Polyethylene and HDPE/High Density Polyethylene. High Density Polyethylenes have more strength than others. MRS (Minimum Required Strength) value has been calculated as 8 for MDPE and 10 for HDPE products. This allows for more fluid to pass through due to a higher strength at lower wall thickness for HDPE. MDPE products, on the other hand, provide advantages in cracks and splitting caused by external impacts with a larger wall thickness value.
