Aquaculture fish cage SDR26

high-density polyethylene (HDPE)plasticround

High-density polyethylene (HDPE) is widely used for the construction of floating cages. Centraltubi Spa with many years of experience in the production of pipes for aquaculture, provide HDPE pipes with excellent characteristics of durability, flexibility, resistance to impacts and ultraviolet radiation. HDPE pipes are usually classified based on minimum resistance required for operating pressure at 20 °C for 50 years, such as PE80 or PE100. However, the working pressure of the pipes is not a relevant feature in the construction of floating cages, as are the intrinsic characteristics of the material, thickness, weight, resilience, strength and flexibility. SDR dimensional ratio is commonly used for the choice of a pipes for aquaculture. This parameter represents the ratio between diameter and thickness of the pipe. High values of the SDR ratio correspond to thinner pipe thicknesses. When pipes are used to build circular cages, a fundamental factor is the torsion capability and the flexural elastic modulus. The first factor influences the minimum bend radius for the pipe, while the second factor influences the effort necessary to obtain a given curvature.
