Sleeve compensator, maintenance free column tube expansion sleeve compensator) said, is the compensation of heat flow strength pipeline equipment, the key to parallel pipeline auxiliary set after the axial thermal deformation displacement, digestion, absorption, compensation is a kind of immediately installed on all transportation corrosion of unilateral or multidirectional fluid mechanics of the pipeline compensator. Sleeve compensator is widely used in urban heating, metallurgical industry, mining, power generation, petrochemical equipment, engineering construction and other manufacturing industries in the transport pipeline. Key to the sleeve specification (core tube), housing, rubber seals, etc. Installation method: 1. The sleeve type compensator should be properly stored during installation to avoid environmental pollution caused by wind, sun and sand. 2. When installing the compensator, it is necessary to check whether the specification and model of the compensator are consistent with the design scheme. The surface of the product should be free from any damage to the product quality, such as stings, pits and serious rusting. Manufactured goods to one-time compensator is 3, the total length is consistent with the template, needn't rashin or narrow, as in the installation of telescopic supervisor on road signs have change, should be carried out again after alignment to install 4, for double torsion compensator, be sure to note in the schematic diagram of the material into the installation, when the material for the steam to prevent air plug the compensator. In order to ensure the compensation amount of the compensator in the two directions is the same, the double compensator must be arranged in the middle of the two supporting points. 5. The pipe welded by electric welding with both sides of the compensator must be cracked to solve the problem. After welding, press test shall be carried out according to the requirements (during the hydrostatic test, the anchor bolts on both sides of the packing chamber shall be tightened without leakage). Be sure to tighten the anchor bolts on both sides of the packing room again after 24 hours of operation. 6. In order to ensure that there is no lateral displacement of the pipeline, the guide bracket is installed on the top of the product along the axial shrinkage type only. When the compensator two guilts have axial displacement, then both sides need to install guide bracket, ensure that the axial displacement of the compensator axis force positive and negative (-) do not exceed one degree. 7. The heat preservation and moisture proof construction of the compensator can be the same as the pipeline, but the telescopic section cannot be restrained. Special circumstances are subject to further consultation.
