During the laying process of PVC pipe and fittings, you need to pay attention to many aspects to ensure the safe, stable and efficient operation of the pipeline system.
First of all, sufficient planning and design should be carried out before laying. Determine the direction, layout and diameter of the pipeline according to the actual use needs. Considering the possible expansion and maintenance needs in the future, reserve a certain amount of space and channels. At the same time, survey the laying site to understand the topography, soil conditions and other factors in order to choose the appropriate laying method and foundation treatment method.
When selecting PVC pipe and fittings, ensure that its quality meets the relevant standards. Check whether there are defects such as cracks and deformations on the appearance of the pipeline, whether the size of the fittings is accurate and whether the fit is tight. Choose products with good corrosion resistance, pressure resistance and temperature resistance to adapt to different use environments.
During the laying process, pay attention to the installation slope of the pipeline. A reasonable slope can ensure the smooth flow of fluid in the pipeline and avoid water accumulation and blockage. Generally speaking, the slope of the drainage pipe should be designed according to the pipe diameter and flow requirements, usually between 2% and 5%. For water supply pipes, a certain slope must also be ensured so that the water in the pipe can be drained during maintenance and flushing.
The foundation treatment of the pipe is also very important. According to the soil conditions and the load-bearing requirements of the pipe, choose a suitable foundation form, such as sand foundation, concrete foundation, etc. Ensure that the foundation is flat and solid, and can evenly support the pipe to prevent the pipe from sinking and deformation. When laying the pipe, pay attention to the horizontality and verticality of the pipe, and use a level and plumb line to check and adjust.
The connection method of the pipe should be correctly selected and constructed. Common connection methods for PVC pipes include glue connection, rubber ring connection, etc. Before connection, clean the interface between the pipe and the fittings to ensure that there are no impurities such as oil, dust, etc. Operate according to the requirements of the connection method, apply an appropriate amount of glue or install a rubber ring to ensure that the connection is tight and leak-free. After connection, it is necessary to cure and inspect for a certain period of time to ensure reliable connection quality.
During the laying process, it is also necessary to protect the pipe from external damage. Avoid stacking heavy objects above the pipe and performing mechanical excavation. If construction needs to be carried out near the pipeline, appropriate protective measures should be taken, such as setting up warning signs and laying protective plates.
Finally, after the laying is completed, the system should be pressure tested and flushed. The pressure test can detect the sealing and pressure resistance of the pipeline system to ensure that there will be no leakage and rupture during use. Flushing can remove debris and dirt in the pipeline to ensure the cleanliness of the fluid. The pressure test and flushing should be carried out in accordance with relevant standards and specifications to ensure that the test results are accurate and reliable.
In short, the laying of PVC pipe and fittings requires comprehensive consideration of multiple factors, from planning and design, material selection, construction technology to later maintenance, etc., to ensure the quality and performance of the pipeline system.
