304 stainless steel interlock fitting connection: At present, a stainless steel pipe connection method with a comparative structure has been adopted at home and abroad, that is, the ferrule type pipe joint connection method. There are many types of ferrule type connections, such as extrusion type, expansion type, self-supporting type, meshing type, etc. According to the standards issued by the National Bureau of Standards, the stainless steel tube ferrule type connection belongs to the extrusion type and the meshing type, and its structure consists of three parts: the joint body, the ferrule and the nut. The key part is the ferrule - a metal ring with a cutting edge (the ferrule for indoor hot water heating is a rubber ferrule).
The working principle of the 304 stainless steel interlock fitting is to insert the steel pipe into the ferrule, lock it with the ferrule nut, resist the ferrule, cut into the pipe and seal it. It does not need welding when it is connected with the steel pipe, which is conducive to fire prevention, explosion-proof and high-altitude operations, and can eliminate the disadvantages caused by inadvertent welding. Therefore, it is a relatively advanced connector in the pipeline of the automatic control device of the oil refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. It is suitable for pipeline connection of oil, gas and water.
304 stainless steel interlock fitting The connection feature of stainless steel tube ferrule type pipe joint is to rely on the ferrule to control the cutting edge and tightly bite the stainless steel pipe wall, so that the high-pressure fluid in the pipe is completely sealed. This joint also has the structural characteristics of anti-loosening, shock resistance and vibration resistance. Meshing long casing fittings are suitable for high pressure systems with small diameters. Extruded tube fittings are suitable for medium and low pressure pipelines, such as indoor hot water heating, water supply, hot water, and gas pipelines.
The current aluminum-plastic pipe connection is the extruded tube joint connection. Because the indoor heating, hot water, water supply, and gas pipelines adopt the above connection process, the threaded connection is reduced, the labor intensity of the plumber is greatly improved, and the project cost is effectively reduced (because the threaded connection of the indoor heating pipeline requires a live joint or a long Wire connection, and the use of ferrule type pipe joints can reduce the number of unions or pipe clamps, filaments, root nuts, and also reduce leakage points. Because special tools and hot welding are not required, in flammable, explosive areas and high-altitude places Pipes are especially suitable.
