HDPE pipes na gudan suna fiye da kudin kowane wani yanki, amma me ya sa kadauwar kowane abu ya zama yawa?

Idan HDPE pipes na gudan suna fiye da kudin kowane mita da PVC pipes, kuma mafarma ba su ke sanya kowane mita na plastic ba; amma suke sanya system na ruwa mai zuwa a matsayin 20 shekara.

• Farko a cikin tsawon zaman kansu shine 2 zuwa 3 kari da kari ko karin; idan aka fuskanta a cikin kowane shekara, abin da ke fiye da kudin kowane yanki yana zama yawa.
• Aiki mai kara kara da rarraba a matsayin ruwa da elektrisiti suka faru a kowane rana;

Ba a hada standard answer don zama mai amfani da irrigation pipes, amma wannan shine shawara: don temporary lines da short-term projects, cheap pipes suna dace; don wani fixed irrigation system da aka plan da zai dauki lokaci ne da biyu shekara ko kafin, domin HDPE irrigation pipes zai zama abin da za a sanya kafin. A lokacin da aka purchase, za a tsoho supplier don aika biyu samples, bury them in the ground da su kula da rainy season—the answer will speak for itself.
