{"id":59,"count":3,"description":"Hydraulic shocks and vibrations in pipeline systems accelerate equipment wear and can cause accidents and damage to components. To prevent such situations, there is a reliable solution - special vibration inserts for pipelines, which reduce the load and extend the service life of the system.\r\n

Vibration spacers (rubber compensators) for pipelines: buy flanged and steel ones in Ukraine<\/h2>\r\nAnti-vibration compensator (vibration insert) is an elastic element <\/span>pipeline fittings<\/span><\/a>, used to absorb vibrations, reduce noise and prevent axial, angular and lateral displacements in the pipeline. <\/span>You can buy a flanged, coupling or steel vibration spacer at an affordable price in the Uxpar online store - models DN15\u2013DN600 and more are available. Rubber anti-vibration vibration spacers are the optimal solution for pumping stations, heating and water supply systems.<\/span>\r\n\r\nThe main purpose of the vibration insert, which is traditionally installed in areas between pumps, compressors, ventilation units and, in fact, the pipeline, is pressure compensation, neutralization of vibrations from pumps and other units, as well as protection of equipment from water hammer. This reduces the risk of damage to pipes and connections in the heating system, at pumping stations, and other industrial facilities. A properly selected vibration insert guarantees the stability of industrial systems, minimizes the risks of breakdowns and emergencies, reduces the noise level, thereby improving working conditions near the facility.\r\n

Design and principle of operation of vibrating feeders<\/h2>\r\nThe anti-vibration insert for the pipeline consists of the following elements:\r\n
    \r\n \t
  1. Rubber insert \u2013 a flexible noise-absorbing element in the central part of the part. It is responsible for the quality of vibration and displacement compensation. It is made of polymer or heat-resistant rubber with additional reinforcement for better strength and resistance to high pressure.<\/li>\r\n \t
  2. Fittings are connecting elements, most often made of stainless, alloy or carbon steel. They come in various types and diameters.<\/li>\r\n<\/ol>\r\nThe principle of operation of the vibration insert is based on its shock-absorbing properties. The elastic compensator absorbs mechanical vibrations, converting them into thermal energy, which, in turn, allows you to reliably isolate vibrating elements from the rest of the pipeline. In addition, the anti-vibration insert compensates for minor thermal expansions and displacements, protecting the pipeline fittings from overload and breakage.\r\n

    Main types of vibrating inserts<\/h2>\r\nVibrating inserts are classified according to various criteria. <\/span>Among the most popular are flanged rubber vibration spacers and steel vibration spacers with a rubber insert. The former are suitable for systems with high pressure and large diameters, the latter for conditions with increased vibration loads.<\/span> One of the key ones is the method of connection to the pipeline. This feature distinguishes models with a coupling and <\/span>flange connection<\/span><\/a>, for welding, with a combined type of fastening. Expansion joints that have coupling and flange connections are the most common.<\/span>\r\n\r\nFlange and coupling vibrator: comparison table\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Disadvantages<\/td>\r\nThey require flanges on the pipes, which increases the cost and installation time.<\/td>\r\nLimited in diameter and pressure. The connection may be less resistant to intense vibration loads.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nExperts also distinguish between vibrating inserts by type of working environment (for cold, hot water, aggressive substances), by design features (single- and double-sphere, with and without limiters), and by operating parameters (operating pressure and temperature).\r\n
