HDPE high-temperature-resistant electric power pipe

Abstract

The utility model provides an HDPE high temperature resistant electric power pipe, relates to pipeline technical field, including outer pipe and working mechanism, when in use, through the precise design of first fixed ring, seal ring, second fixed ring and fixed insert ring of connecting subassembly, guaranteed the leakproofness and steadiness of pipe junction, effectively defend the external environment to internal cable, and the electric power pipe of high temperature resistant performance of external environment. A buffer layer and an inner wall wear-resistant layer in the auxiliary assembly play important roles in buffering impact and reducing wear, the service life of the power pipe is remarkably prolonged, the anti-seismic and shock-absorbing assembly can absorb and disperse external shock by applying an efficient shock-absorbing system composed of a bottom plate, a first base, a telescopic column, a shock-absorbing spring and a second base, and the shock-absorbing effect is improved. The cable is powerfully protected from being damaged by vibration, stable installation and convenient maintenance of the cable are ensured by an inner pipe material and a connecting flange in the inner pipe assembly, and the thermal stability and the structural strength of the inner pipe are enhanced by a heat conduction layer and reinforcing ribs in the reinforcing assembly, so that the stable performance of the electric power pipe can still be kept in a high-temperature environment.
