The Main Purpose Of Metal Winding Grommets Is Really A Lot

Doit Rubber Products Co.,Ltd | Updated: Oct 24, 2017

The main purpose of metal winding Grommets is really a lot
The main purpose of metal winding Grommets is really a lot, periodical changes, there are shock or vibration of the occasion. It is widely used in petrochemical, mechanical, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace, etc., which are valves, pumps, heat exchangers, towers, manholes, hand holes and other flange joints.
In the flange design for the convenience of installation, according to Grommets caliber size, in the Grommets peripheral welding 2 - 8 positioning belt, so that the positioning buckle in the flange hole, to prevent the installation of Grommets shift or fall off, save Auxiliary materials and working hours. Generally divided into the following types:
Metal wire Grommets are made of high quality SUS304, SUS316 ("V" or "W") metal belts and other alloy materials with graphite, asbestos, polytetrafluoroethylene, non-asbestos and other soft materials alternately overlapping spiral wound The start and end are fixed by spot welding. Metal-wrapped Grommets for semi-metallic mats in resilient best Grommets, metal wound Grommets structural density can be made according to different locking force requirements, and use the inner and outer steel ring to control its maximum degree of tightness, winding Grommets Flange sealing surface surface accuracy is not high. Metal winding Grommets are particularly suitable for applications where the load is not uniform, the jointing force is easy to relax, the temperature and pressure are periodically changed, there is shock or vibration. Wrapping Grommets is the original seal of the valve, pump, heat exchanger, tower, manhole, hand hole and other flange connection.
Metal Winding Grommets are widely used in a sealed Grommets, semi-metallic pad for the best resilience of the Grommets, from the V-shaped or W-shaped thin strip with a variety of filler material alternately wound, high temperature, high pressure And to adapt to the conditions of ultra-low temperature or vacuum use, by changing the Grommets material composition, can solve a variety of media on the Grommets chemical corrosion problem, the structural density can be based on different locking force requirements to produce, to strengthen the main body and accurate positioning, Winding Grommets with metal inner ring and outer ring, the use of internal and external steel ring to control its maximum degree of compression, Grommets contact flange sealing surface surface accuracy is not high.
Metal winding Grommets is an important sealing element, widely used in petroleum, chemical, metallurgy, power generation, shipbuilding and other industries, is the current pressure pipelines, valves, pumps, heat exchangers and other equipment, the key components of static seal. Choose and use high-quality metal winding Grommets, to reduce and eliminate the run, run, drop, drain, to ensure the safety of the host equipment, the normal operation of the pressure pipeline, is of great significance.

Buy metal winding Grommets products should note the following:
1, select Grommets according to working conditions.
2, Grommets main body surface does not allow the impact of sealing performance of the scars, voids, rugged and rust defects.
3, compression rate, rebound rate and sealing performance is sealed Grommets important performance indicators, in general, to meet the requirements of the compression rate under the premise of the higher the better the rebound rate; and meet the requirements of the rebound rate of the premise , The compression rate of the test value is also much better. Should choose a good sealing performance, moderate compression rate and rebound as much as possible products.
