The advantages of circulating water steel expander when used

Circulating water steel expander, is used for pipeline expansion or expansion deformation can achieve expansion deformation, reduce the stress when the pipeline and equipment connection. According to different parts, it can be made into different pipe diameters and different installation positions. It is a kind of widely used equipment that can play the role of expansion and compression in the pipeline. It can also be used as an elastic element such as pipeline and valve for mutual compensation expansion and deformation between pipeline transportation and installation.
Composed of two parts: when the pipeline or equipment is subjected to radial and axial displacement, automatically compensate the displacement between the two flanges under the condition of not damaging the sealing device, in order to ensure the normal work and displacement of the pipeline or equipment, while bearing the role of power. It is used for the installation of pipelines in thermal, metallurgical, chemical and paper industries to compensate for the deformation and vibration caused by the operation of pipelines. So the expander is what we often say is the compensation water pipe or the expander. Most of these products are made of metal materials, there are also some metal products can play a certain protective role, such as having a seal ring and good corrosion resistance, in use is not easy to aging and other characteristics.
Flexible expanders are used in the connection of two flanges of the pipeline, with a seal ring between the pipeline and the flange to achieve effective waterproof sealing performance; for large diameter casing type expanders, especially in cold areas, can effectively prevent deformation caused by cold and hot contraction of the pipeline. Product scope of application: applicable to chemical, metallurgical, electric power, heating, refrigeration, shipping, construction, machinery, petroleum, paper, environmental protection and other industries of various types of pipeline installation. There is enough compensation capacity to compensate for the displacement between various types of pipe systems and flanges. The product has the characteristics of good corrosion and heat resistance, easy installation, long service life, etc. Can be manufactured according to user requirements installed in the corresponding pipeline to compensate the pipeline axial, lateral, angular displacement and the amount of pipeline compensation due to temperature changes caused by displacement or axial distortion.
