In recent years, due to drought, global warming and of course, increase in surface water evaporation, the need for new irrigation methods in the agricultural sector is more important than ever. One of these methods is drip irrigation using polyethylene pipes, which reduces water consumption by about 40%. According to this global problem, the issue has received a lot of attention recently. Moreover, considering the recent policies of the country on the production of polyethylene (PE) pipes with specific quality of their thin wall, which is widely used in irrigation nowadays and required improvement. to increase their quality, this research was performed. To obtain a pipe with satisfying qualities, it is necessary to find the right type of polymer and additives to achieve the performances for the pipes, such as the right optical and mechanical properties. To do this, different grades of polyethylene have been employed and alloyed together, soot and masterbatch were added. Finally, by adding nanoclay and fly ash, the effect of these additives has been investigated. To fabricate the specimen with an extruder, the materials are completely combined and tested specimens are produced by using an injection molding machine and a roller mixer. According to observations, soot with about 3 wt.% carbon shows the best desired optical and mechanical properties. In addition, the quality of soot and masterbatch results in suitable effects on dyeing and using right masterbatch could be a better choice because of carbon dispersion than soot. Also, some small changes in production methods and effective parameters such as pipe cooling time, cause completely different results. These findings can be used for equipping the production line and manufacturing raw materials converted to PE pipes.
