Pipeline retractors are connectors that compensate for dimensional changes caused by thermal expansion and contraction in pipe connections. There are two most commonly used pipe retractors, one is a rubber pipe retractor, and the other is a metal pipe retractor. Small size, light weight, good flexibility, easy installation and maintenance. Here we introduce: Pipe expansion device installation methods and installation considerations. Pipe expansion device installation method: Pipeline retractors can be used mainly for loose pipe connection of hardware pipes. The pipe retractor is mainly connected by all the bolts, making it a whole, and has a certain amount of displacement, but also can withstand the axial pressure of the pipeline. When installing this product, it is necessary to first pay attention to the following points: 1. The pipeline retractor should be checked for its model, specifications and piping configuration prior to installation and must meet the design requirements. 2. The retractor with inner sleeve should pay attention so that the direction of the inner sleeve is the same as that of the medium, and the hinge plane of the hinge-type retractor should be consistent with the displacement plane. 3. The “cold tight†retractor is required. The auxiliary components used for the pre-deformation should be removed after the pipe is installed. 4. It is forbidden to use the method of deformation of the retractor to adjust the installation of the pipeline so as not to affect the normal function of the retractor, reduce the service life, and increase the load of piping, equipment and support members. 5. In the installation process of the pipeline retractor, welding slag is not allowed to splash on the surface of the wave shell, and the wave shell is not allowed to be subjected to other mechanical damage. 6. After installation of the pipeline retractable pipe system, it is also necessary to remove the yellow auxiliary positioning components and fasteners used for installation and transportation on the wave retractor as soon as possible, and adjust the position limiting device to the specified position according to design requirements. Pipeline has full compensation capability under environmental conditions. Pipe expansion device installation notes: 1. Installation of pipeline retractors shall be stopped in accordance with the piping system construction drawings and the installation of pipeline retractors. 2. The pipeline for installing the pipeline retractor must be appropriately guided and fixed so that the retractor can have a positive effect. Therefore, the arrangement of the guide and the fixed support hanger must be severely stopped according to the design-related technical materials. Refer to “Guide for Corrugated Shrinkage Units†for guideline and fixing bracket setting guidelines. 3. The bellows used for shrinkage joints are formed with thin-walled stainless steel plates. Therefore, during the transportation, hoisting and welding periods, it is necessary to take care not to knock, scratch, arc, weld, etc. the damage caused by bellows. 4Before installation, clear foreign objects on the outside of the bellows and pipe shall be provided to ensure normal operation of the bellows. 5. The shrunk section with a flow direction request should stop the installation at the request of the media flow arrow. 6. In order to make the bellows in a superior task configuration, the device can not use the deformation of the contraction joints, including axial, lateral, and other deformations to correct the pipe system status error. Edit summary Pipeline retractor installation methods and installation notes are introduced here, I hope to help you, more information, please pay attention to this site.
