The ferrule joint is widely used in daily life and is a well-known tool accessory. The ferrule type joint has the advantages of simple structure, convenient use and no welding, which brings a lot of convenience to people's production and life.
The ferrule type pipe joint consists of three parts: the joint body, the ferrule, and the nut. When the ferrule and the nut sleeve are inserted into the joint body on the steel pipe, and the nut is tightened, the outer side of the front end of the ferrule fits the conical surface of the joint body, and the inner edge evenly bites into the seamless steel pipe to form an effective seal.
The working principle of the ferrule joint:
The ferrule joint is especially suitable for working under the conditions of high pressure, vibration and high sealing performance.
1. When connecting the pipeline, it must be assembled according to the specified tightening force. If the ferrule is severely deformed during pre-installation, the sealing effect will be lost.
2. It is forbidden to add fillers such as sealant. In order to achieve better sealing effect, some people apply sealant on the ferrule, as a result, the sealant is flushed into the hydraulic system, causing failures such as blockage of the orifice of hydraulic components.
3. When connecting the pipeline, the pipe should have enough deformation allowance to avoid the pipe being subjected to tensile stress.
4. When connecting the pipeline, it should be avoided to be subjected to lateral force. If the lateral force is too large, the sealing will not be tight.
. When connecting the pipeline, it should be tightened at one time to avoid multiple disassembly, otherwise the sealing performance will be deteriorated.
6. Detailed inspection after installation: The pipe can be removed to check whether the assembly meets the requirements; the pipe at the end of the ferrule should have a uniform slight bulge; the ferrule cannot slide back and forth, but a slight rotation is allowed.
