Description

Technical Field

[0001] The present application relates to the technical field of pipeline connection, and in particular to an easily connectable stainless steel pipe assembly. Background Art

[0002] Stainless steel pipe is a hollow long round steel. Because of its good mechanical properties and corrosion resistance, it is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. Existing stainless steel pipes are often connected and fixed by a compression connection method. The so-called compression connection is a method of connecting and sealing pipes and fittings by cold extrusion. First, the pipe with a sealing ring pre-sleeved is inserted into the port of the fitting, and then the connection section of the port is circumferentially pressed from the outside, so that the connection section of the port and the inserted pipe are deformed and locked together, thereby achieving an effective sealing connection between the pipe and the fitting. However, this compression connection method requires additional equipment to apply a certain amount of pressure to it, which is troublesome to operate and cannot be disassembled. At the same time, if a connection error occurs during the connection process, the stainless steel pipe is easily deformed by the external pressure, which eventually causes the stainless steel pipe to be scrapped and damaged.
