Requirements and applications of rubber flexible connections
The advantage of rubber flexible connection is the surface layer is matte, less pollution of the environment, the defect is due to the surface layer of the original element suffered destruction, corrosion resistance work ability has a corresponding reduction. And the stronger corrosive natural environment of the region most of the provisions of the bright surface, the key reason is due to the bright surface has an invisible protective film, can avoid the rubber soft connection surface is leached, and not easy to scale, the accumulation of stains will make the rubber soft connection rust leading to leaching.
Rubber flexible connection is to rely on its surface layer produced by a layer of extra-thin and firm and delicate smooth chromium-rich air oxide film (protective film), to avoid the re-penetration of oxygen molecules to, again air oxidation, and get the ability to work against rust. Once there are various reasons, this kind of plastic film suffered continuous destruction, gas or liquid oxygen molecules will continue to penetrate to or metal materials in the iron atoms continue to precipitate out, produce loose compounds, metal surface also suffered continuous rust. The surface of the rubber flexible connection is stored with other chemical elements of soot or semi-animal metal material particles appendages, in the wet and cold air, appendages and rubber flexible connection of condensed water, the two will be connected into a micro-charge battery, causing electrochemical corrosion, protective film damage, called electrochemical reaction.
The rubber flexible connection must not be dragged out or dragged out from the tube shelf without smooth surface to prevent causing concave groove marks. The rubber flexible connection should be maintained sharp, and the rubber flexible connection should not be cut too deep at each rotation. And ensure that there is no burr at the end of the tube and no oval deformation after laser cutting. This facilitates the rubber flexible connection in the installation of the whole process according to the smooth, and not easy to ruin the rubber flexible connection of the sealing part.
