The sealing principle of compression pipe fittings
involves how the compression ring achieves effective sealing under the action of compression force.
Elastic deformation of compression ring
Compression rings are usually made of some elastic material such as rubber, polymer or metal. This elasticity allows the compression ring to reversibly deform when exposed to external forces.
When the compression nut is tightened, the force exerted on the compression ring causes the compression ring to elastically deform. This deformation is limited because elastic materials have a certain limit, and once the limit is reached, no further deformation occurs. During this process, the compression ring conforms to the surface between the pipe and compression nut, forming a seal.
Due to the elasticity of the compression ring, it is able to adapt to slight deformations and vibrations in the piping system. This adaptability ensures that the compression ring maintains its sealing performance under varying temperatures, pressures and environmental conditions.
Adjustment of compression force
Control tightening force
The effectiveness of the seal is directly related to the tightening force exerted on the compression ring. By controlling the tightening force, the degree of compression of the compression ring can be adjusted, thereby affecting the tightness of the seal.
Adapt to different conditions
Different application scenarios may require different tightening forces, depending on the operating pressure of the piping system, the temperature range, and the nature of the piping material. Compression fittings are usually designed with these factors in mind to ensure stable sealing performance under various operating conditions.
The working process of sealing principle
Putting the compression ring on the end of the pipe: When installing compression fittings, the compression ring is first put on the end of the pipe.
Tighten the compression nut: Next, by tightening the compression nut, the force exerted on the compression ring causes it to elastically deform, forming a seal.
Creates an even seal: Compression rings create an even seal between the pipe and compression nut, preventing liquid or gas leakage.
Maintain adaptability: Due to the elasticity of the compression ring, it is able to adapt to minor deformations in the piping system and maintain sealing performance.
Tighten the compression nut counterclockwise: When it is necessary to disassemble the compression pipe fitting, by tightening the compression nut counterclockwise, the compression force is reduced and the compression ring gradually returns to its original shape, allowing the pipe connection to be easily disassembled.
