2, as the PVC tube is soft and its mechanical strength is not high, it is necessary to strictly prevent physical damage. After installation, it is strictly prohibited to knock, touch, smash and press. After covering up, the pipeline should be covered with protective measures. Some measures must be taken to prevent the pipes from breaking down before they are closed, because the elements of the PVC pipe are very important. It is easy to neglect that chemical damage is prevented in construction. When installed outdoors or in pipelines with direct sunlight, a dark protective layer should be wrapped to prevent chemical damage caused by sunlight.
