AI Technical Summary
Existing pipeline repair pipe joints are fixed by a single external clamp, which cannot provide sufficient fixing force, which can easily cause the pipeline to loosen or fall off, causing leakage or safety issues.
The double fixing structure of inner and outer clamping is adopted. The pipe is clamped from the outside to the inside through the outer clamping, and the inner clamping is clamped from the inside to the outside. Combined with the design of the limiting plate and threaded rod, the pipe is securely fixed.
It greatly reduces the risk of water leakage caused by accidental falloff or loosening of the pipeline, ensures stable and fixed pipes, and avoids leakage and safety issues caused by traditional single external splints.

They are usually used to connect broken, cracked or leaking pipelines to restore the integrity and function of the pipelines. Using pipeline joints for repair can avoid the trouble and cost of replacing the entire pipeline section, saving time and cost. Importantly, when selecting and using pipeline joints, it is necessary to ensure the compatibility between the joints and the pipelines according to the specific pipeline type, material and diameter, and operate correctly according to the installation instructions.
[0003] When the existing pipeline joints for pipeline repair are in use, they are only fixed by a single external splint.

Through the double fixation inside and outside, the risk of water leakage caused by accidental falling off or loosening of the pipeline is greatly reduced, ensuring the stable fixation of the pipeline, and avoiding the problem that the traditional single external splint fixation cannot provide sufficient fixing force, which easily leads to the loosening or falling off of the pipeline, thereby causing leakage or other safety problems.
