Introduction: The expansion joint is composed of body, sealing ring, gland, expansion short pipe and other main parts. A limiting device is added to the original performance of the loose sleeve expansion joint, and the double nut is used to lock the large expansion joint. The pipeline can freely expand and contract within the allowable expansion amount

Expansion joint It is composed of body, sealing ring, gland, telescopic short pipe and other main parts. A limiting device is added to the original performance of the loose sleeve expansion joint, and the double nut is used to lock the large expansion joint. The pipeline can freely expand and expand in the allowable expansion amount. Once it exceeds the limit, it can ensure the stable operation of the pipeline. It is especially suitable for the connection in the pipeline with vibration, certain slope and bend. Luoying's years of experience in installation.
1. The pipeline design, compensation design, strength and stability design standards can not be met during installation.
2. The improper use of pipe fittings and pipes, or the application site does not meet the requirements and there are quality problems, and the technical measures to be adopted for different systems are not enough.
3. The selection of expansion joint interface mode is not good, and the engineering construction is not easy to ensure, leaving a hindrance.
4. Poor operation quality of engineering construction, leaving trouble. 5. Because of the temperature difference caused by the temperature change, the thermal expansion and cold contraction movement of the pipe changes the stress situation of the pipe fitting, and the stress distribution and size can not be compensated and controlled, which will cause many problems.
6. The water hammer makes the water pipe suddenly suffer from great internal pressure and collision, resulting in drawing, bending, twisting, loosening and displacement, resulting in system striking force and vacuum negative pressure. If the pipe network system does not have sufficient strength, it will burst.
7. Overpressure and overheating have great damage to plastic pipes.
8. High air flow erosion has great damage to copper pipe.
9. Resonance has great influence on the interface.
The above is a detailed introduction to the leakage prevention measures of expansion joint. The expansion joint produced by Shanghai Luoying is strictly in accordance with the national standard system, and the double flange is produced Telescopic device Good quality, low price, patented products, worthy of your trust!
