S313 flange type expansion what is its role?

Details of S313 flange type expansion.
1 . Before installation, the flange type expander should be checked for its type, specification and pipeline configuration to meet the design requirements.
2 . For the flange type expander with inner sleeve, attention should be paid to make the direction of the inner sleeve consistent with the direction of medium flow, and the hinge rotation plane of the hinge type flange type expander should be consistent with the displacement rotation plane.
3 . For flanged expanders that need to be "cold tightened", the auxiliary components used for pre-deformation should be removed only after the pipeline is installed.
4 . It is strictly forbidden to use the method of deformation of flange type expander to adjust the installation of pipeline overrun, so as not to affect the normal function of flange type expander, reduce the service life and increase the load of pipe system, equipment and supporting members.
5 . During the installation process, welding slag is not allowed to splash on the surface of the wave shell, and other mechanical damage to the wave shell is not allowed.
6 . After the installation of the pipe system, the yellow auxiliary positioning components and fasteners used for installation and transportation on the wave flange type expander should be removed as soon as possible, and the limit device should be adjusted to the specified position according to the design requirements, so that the pipe system has sufficient compensation capacity under environmental conditions.
7 . All movable elements of flange type expander shall not be jammed by external components or restrict its range of activities, and shall be the normal action of each movable part.
S313 flange type expander is produced in the process of customer engineering use, we found the limitations of flange type loose set expansion joint, after many practical experiments, gradually out of S313 expander, the is on the basis of flange type loose set expansion joint additional flange expansion tube, for the flange type connection pipeline installation to provide convenience; Secondly, the use of pressure plate and flange short pipe between the limit device, for the operation of the expander Secondly, the use of the limiting device between the pressure plate and the flange short pipe can play a protective role for the operation of the expander, and also play a driving role for the axial force generated by the pipeline operation. The emergence of new products has played a positive role in the user experience and the use of multiple fields. luoying has been committed to the production of the telescope series products for many years and designs non-standard and efficient new products according to the actual use environment of the project, which is unanimously praised by customers of medium and large projects.
