I. Anti-Aging Issues

　　( 1) PE Water supply pipes can be either blue or black with a blue stripe extruded on the surface; the latter generally offers better UV resistance and aging protection.

　　( 2) Polyethylene pipes should not be openly installed; if open installation is unavoidable, it is recommended to protect them with conduit.

　　( 3) Polyethylene pipes shall be protected from direct sunlight during transportation and storage, and the duration of on-site storage should be kept as short as possible.

　　( 4) Those that have undergone anti-aging treatment PE Even if the above two points are violated, the product can still be used, but its service life will be significantly shortened.

II. Regarding Temperature-Related Issues

　　( 1) PE pipe material The temperature of the conveyed medium is higher than At 20°C, the nominal pressure of the selected pipe material shall be determined in accordance with the ‘Technical Code’. 4.1.1 The “formula” calculation will yield a value greater than the design pressure of the pipeline network;

　　( 2) ‘Technical Regulations 4.2.4 Clause: The clearance between buried polyethylene pipelines and heating pipelines shall not be less than 1.5m , and ensure that the surface temperature of the polyethylene pipe does not exceed 40 Calculate the spacing under ℃ conditions;

　　( 3) For locally exposed pipelines equipped with sleeves, it is also necessary to verify whether direct sunlight on the sleeves causes the polyethylene pipe surface temperature to exceed 40 ℃; otherwise, an insulation layer shall be added.

Therefore, it is crucial to implement measures that mitigate axial deformation caused by seasonal temperature variations when laying polyethylene pipes. The fixation methods required to control such expansion and contraction are often simple and cost-effective, leveraging the unique property of polyethylene—its stress-relaxation capability—to manage mechanical movement and deformation. 。
