Types of Nipples in Pipe Fittings

Pipe nipple is a detachable connection between oil pipe and oil pipe, oil pipe and hydraulic parts. It should have the characteristics of convenient assembly and disassembly, firm connection, reliable sealing, small size and large flow capacity. Commonly used types of pipe nipples in hydraulic systems are: welding type; ferrule type; flaring type; crimping type.


1. Welded pipe nipple: It is characterized by firm connection, using spherical surface for sealing, simple and reliable. However, thick-walled steel pipes are inconvenient to assemble and disassemble and the welding quality must be guaranteed.


2. Ferrule type pipe nipple: The feature is that the ferrule is used to block the oil pipe for sealing, the axial size is not strict, and the assembly and disassembly are convenient. The radial dimensional accuracy of the tubing is required to be high, so cold drawn seamless steel pipes should be used for this purpose.


3. Flaring type pipe nipple: The flaring at the end of the tubing is used for sealing under the compression of the pipe sleeve, and the structure is simple. Types of pipe nipples are suitable for the connection of low-pressure pipes such as copper pipes, thin-wall steel pipes, nylon pipes and plastic pipes.


4. KBG pipe nipple: used to connect high-pressure hoses; suitable for medium and low pressure systems.
