The working life of HDPE Double-wall Corrugated Pipe depends mainly on the maximum stress generated during the working process. In order to reduce the stress, it is generally achieved by reducing the working displacement of the HDPE double-wall corrugated pipe and reducing the working pressure. In the general design, the working displacement of the HDPE double-wall corrugated pipe should be less than half of its allowable displacement, and its working pressure should be less than half of the pressure resistance of the HDPE double-wall corrugated pipe.
The test of the produced HDPE double-wall corrugated pipe proves that if the HDPE double-wall corrugated pipe works according to the above specifications, its service life can reach 50,000 times.
According to the nature of the working pressure, the allowable displacement of the HDPE double-wall corrugated pipe is also different. Generally, the HDPE double-wall corrugated pipe only bears the axial load (tension or pressure), and its allowable displacement can be in the effective length of the HDPE double-wall corrugated pipe. It is selected between 10% and 40%. When the HDPE double-wall corrugated tube is subjected to lateral concentrated force, torsional moment or comprehensive force, the allowable displacement of HDPE double-wall corrugated pipe should be appropriately reduced.
The use of multi-layer HDPE double-wall corrugated pipes can reduce the stress caused by stiffness and deformation, thus greatly improving the life of HDPE double-wall corrugated pipes.
HDPE double-wall corrugated pipes will have different service life when operating under the same conditions and different working pressure properties (constant or alternating load). Obviously, HDPE double-wall corrugated tubes have a shorter life than those under constant load when operating under alternating loads.
