Aban Bespar Parsian Industrial Group has been able to be one of the largest producers and suppliers of all types of pipes and fittings needed by farmers, according to the knowledge and technology of production of polyethylene pipes and fittings according to national and international standards. Due to the problem of lack of water as well as better management and cultivation of out-of-season crops, greenhouse cultivation has been increasing day by day, the prevailing conditions in the greenhouse have made polyethylene pipes and fittings a suitable substitute for other pipes and fittings. Easy transportation and installation, reasonable price and resistance of polyethylene pipes and fittings are some of the advantages that encourage farmers to purchase this product. The use of irrigation tape, main and secondary pipes as well as related connections in the greenhouse allows us to have a better water management for the plant. According to the area of the greenhouse and the type of greenhouse cultivation that we have, appropriate pipes and fittings are used. The drainage system is one of the main options in the construction of a greenhouse that does not damage the plant and excess water is removed from the reach of the plant. Artificial has been able to solve the needs of farmers regarding this issue.
