Type: Direct-buried sleeve compensator It adopts advanced sealing structure and sealing materials, and is suitable for hot water, steam, grease and other media. The sliding movement of the outer sleeve achieves the compensation of thermal expansion. Two-way sleeve compensator It has a telescoping core tube in both directions of the ordinary outer sleeve. The compensation amount is twice that of the ordinary type, and it is used for two-way compensation, reducing the length and cost of using two ordinary types. Disposable sleeve compensator It is used to weld the two contact surfaces of the pipeline after preheating and expansion of the directly buried pipeline. The outer tube and the core tube can no longer move relative to each other, and then landfill, which has the same life as the pipeline. Feature: 1. Compensate the axial, lateral and angular thermal deformation of the absorption pipeline. 2. The expansion and contraction of the corrugated compensator is convenient for the installation and disassembly of the valve pipeline. 3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline. 4. Absorb the deformation of the pipeline caused by earthquake and ground subsidence. Application: It can be widely used in trenches and elevated pipelines in pipeline networks such as chemical industry, petroleum, thermal power, metallurgy, urban central heating and heating.
