Summer will come slowly after a period of time. Improper operation during construction will easily lead to pipe deformation and even pipe breakage during pressure test. What problems should be paid attention to during pipe construction in summer? according to Pipe manufacturer Multiyear Pipe installation The experience now describes the precautions as follows:

When pipes are stored in summer, they are more likely to deform due to hot weather. The height of pipes shall not exceed 1.5m, and the sockets shall be staggered.

If the construction is not carried out for a short time, in order to prevent the pipe body from being exposed to the sun for a long time, and the pipe body from aging, the pipe body should be timely covered with a shading net.

During the construction of water pipes in summer, special attention should be paid to the amount of glue. If the glue volatilizes quickly in the closed space in summer, it should be inserted immediately after coating. After the insertion, it should be maintained for 30s before moving. During the connection of pipes, an extension joint or looper should be added every 50 meters. After the use of glue, the bottle cap should be covered in time, Avoid the volatilization of adhesive due to high temperature, which will affect the bonding effect when it is used again.

In summer, there are many small animals. When the pipeline is installed, special attention should be paid to the coverage of the pipe orifice to prevent small animals from entering the pipeline to affect the pipeline pressure and normal water supply.

There is a lot of rain in summer. When the pipe construction is completed, it should be backfilled in time to prevent the collapse of the pipe trench from affecting the normal construction and damaging the pipe body, causing trouble.

During backfilling in summer, due to the large amount of rainwater, it is necessary to tamp during backfilling to prevent cavities in the pipe trench, which may cause uneven stress on the pipe body during the pressure bearing process and affect the compressive capacity of the pipe.

Before the pressure test of the pipeline, the exhaust valve shall be installed at the beginning, end and high point of the pipeline. The length of the pressure test shall be 500m. During the pressure test, the pressure shall be slowly increased and continuous exhaust shall be required. When the required hydrostatic pressure is reached, the pressure shall be held still for 1 hour.

The above is Home piping -We hope that we can help you with some problems that we need to pay attention to during pipeline construction in summer.
