1. Improve the pull-out resistance and make the connection safer. The pull-out resistance of double-clamped pipe fittings is more than 1.5 times that of single-pressed pipe fittings;
2. Improve vibration resistance. When the pipeline vibrates, the destructive force first acts on the socket outside the sealing ring of the pipe fitting, effectively protecting the R port where the sealing ring is stored from deformation and preventing water leakage caused by vibration;
3. Improve the bending resistance. When the pipeline is subjected to external force, the external force first acts on the socket outside the sealing ring of the pipe fitting, which effectively protects the R port where the sealing ring is stored from deformation, and prevents water leakage due to the deformation of the sealing ring due to external action £»
4. Single-compression products can pass the acceptance during the acceptance check, but often leaks after the decoration. This is mainly because the external force of the workers exerted an influence on the pipeline during the subsequent decoration construction, and changed the socket of the pipe fitting sealing ring. Caused by the shape. However, the double clamp pressure is more resistant to external force damage due to the socket outside the sealing ring, and external force damage is consumed in the socket protection section.
