Wear-resistant pipeline compensator for electric power

Abstract

The invention provides a wear-resistant pipeline compensator for electric power. The wear-resistant pipeline compensator for electric power comprises a compensator body, wherein the compensator body comprises a compensation pipe, a plurality of corrugated segments are arranged in the middle of the compensation pipe, a mounting ring is welded to the position, close to one opening, of the inner wallof the compensation pipe, a protective cover is arranged at the top of the mounting ring, and a wear-resistant pad is arranged at the top of the mounting ring. The mounting ring is directly welded tothe inner wall of the compensation pipe to provide positions for mounting the protective cover and the wear pad. The mounting ring, the protective cover and the wear-resistant pad are directly detachably fixed. After the protective cover and the wear-resistant pad are damaged, replacement can be carried out, and the pipeline compensator can be prevented from being directly replaced. The wear-resistant pad can achieve a protective effect on the mounting ring. Slag enters the compensation pipe from one end provided with the wear-resistant pad and makes direct contact with the wear-resistant pad, so that the mounting ring can be protected, and long service life of the mounting ring is ensured.

Description

technical field [0001] The invention relates to the field of pipeline compensators, in particular to a wear-resistant pipeline compensator for electric power. Background technique [0002] Pipeline compensators, also known as expanders or expansion joints, expansion joints, are mainly used to compensate for thermal expansion and contraction of pipelines caused by temperature changes. If the pipe is not completely free to expand or contract when the temperature changes, thermal stresses will develop in the pipe. This stress must be considered in the pipeline design, otherwise it may cause the rupture of the pipeline and affect the normal production. As an important part of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines. [0003] There are many types of pipeline compensators, which are divided into axial type, transverse type, angular type and pressure balance type according to the compensation type; the axia...
