The working principle of the quick joint of the stainless steel sleeve is that the steel pipe is inserted into the sleeve, and the sleeve moves axially in the inner cone hole of the joint body by rotating the nut. At the same time, the cutting edge of the sleeve shrinks radial under the action of reaction, and cuts into the surface of the pipe to form an effective seal.
A fitting that can connect or disconnect pipes without the need for tools
Parameter table:
Application field
Stainless steel fasteners are widely used in the following fields:
Petrochemical: Used for oil refining, chemical industry and other pipeline connection, withstand high pressure, high temperature and other harsh conditions.Sampler Sparepart
Natural gas: used for the connection of natural gas transmission pipelines to ensure the safe transmission of media.
Food and pharmaceutical: Because stainless steel has good corrosion resistance and hygiene, it is also commonly used for pipeline connections in food,Custom sampling system pharmaceutical and other industries.
Instrumentation: In the automatic control device pipeline, stainless steel fasteners can provide stable and reliable connections.
304 Quick connection Pressure instrument Structural composition
Stainless steel fastener mainly consists of the following parts:
Joint body: usually stainless steel material, with a certain inner cone, used to achieve sealing with the sleeve.
Bushing: A metal ring made of stainless steel with a cutting edge at the front for cutting into the pipe and sealing it.
Nut: Used to lock the sleeve, by rotating the nut to produce radial contraction of the sleeve, so as to tightly fit the pipe.
Body material: stainless steel(Select the appropriate stainless steel material according to the use environment and medium, such as 304, 316)
