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 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. Used in the installation of pipelines in thermal, metallurgical, chemical and paper industries, to compensate for the deformation and vibration generated by the operation of the pipeline. Such as having good sealing ring and corrosion resistance, not easy to aging in use and other characteristics.
For large-caliber 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 the chemical industry, metallurgy, electric power, heating, refrigeration, ships, 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. Compensation of pipeline axial, lateral, angular displacement and the amount of pipeline compensation due to temperature change caused by displacement or axial distortion.
