Composition of pipe expander and its role

Pipeline expander is composed of body tube, expansion tube, pressure lang, sealing ring, is a pump, valve, pipeline and other equipment and pipeline connection between the pipe fittings, used in water supply and drainage projects, for urban water tower, pump room water meter and valve installation and removal to provide a great convenience. Can compensate the pipeline medium expansion caused by the displacement and axial, lateral, angular and lateral displacement, displacement volume changes brought about by the deformation of the displacement compensation amount limit, effectively avoid the pipeline caused by medium expansion and contraction of the pipeline deformation damage or damage to the valve equipment, to avoid the pipeline running process due to thermal expansion and contraction caused by the pipeline damage; will not be damaged by improper installation of the valve.
The pipeline expanders are connected by full bolts during installation to make them integral and have a certain displacement, which is convenient for installation. It can withstand the axial pressure of the pipeline. This makes it possible to adjust the installation size according to the site during installation and maintenance, and not only improve the work efficiency when working. At the same time, because of the connection with the pipeline, its pipe diameter and expansion length can be freely expanded or displaced according to the user's requirements, independent of the pipeline material and pipe diameter.
The expander is suitable for thermal power plants, petroleum and other industries, for water supply and drainage projects, gas pipeline projects and heating systems. The installation of the pipeline should ensure the required installation height and level of the expander to avoid displacement and damage to the pipeline; the expander should be installed in a location that is susceptible to water rushing or easily damaged by mechanical extrusion of the pipeline or valve and displacement. In the process of use, the expander must be regularly checked for sealing and often repair or replace the damaged expander. The expander should be checked regularly in use for looseness or collision between the parts to prevent the deformation and damage of the expander due to the displacement of gas and liquid in the pipeline system.
