PVC Pipe Installation Methods:
1. When connecting PVC pipe to steel pipe, first apply glue to the joint. Heat the PVC pipe to soften it and prevent it from burning. Then, insert the socket into the steel pipe and allow it to cool.
2. Avoid contact with water during bonding. The PVC pipe must lie flat in the trench. Backfilling should begin 24 hours after the joint. The pipe must be tightly sealed around the perimeter, with extensive backfill at the joint.
3. After impregnating fiberglass cloth with a resin solution containing a glass fiber curing agent, wrap it evenly around the leaking pipe and allow it to solidify to form fiberglass reinforced plastic.
4. The patching method is primarily used to address leaks in small holes and joints in pipes. Select a pipe of uniform diameter, split it longitudinally, roughen the inside and outside surfaces, apply glue, and securely seal the pipe to the leaking area.
Standard Requirements for PVC Pipe Use:
First, the surface must be smooth and flat, free of defects such as dents and discoloration that would affect the appearance. PVC pipes should be opaque. Lengths are generally 4 meters, though 6, 8, and 12-meter lengths are also available. Specific lengths can be determined by negotiation with the manufacturer. The wall thickness of the PVC pipe must meet standard specifications, and the minimum depth of the fitting opening must meet specified requirements.
Precautions for Using PVC Pipe:
1. Before installation, be sure to familiarize yourself with the entire drainage system design drawings. Inspect the overall structure on-site to verify that all pipes are properly arranged and aligned. Any problems identified should be addressed promptly.
2. For PVC pipe, determine the drainage slope and hanger brackets based on coordinates. After all connections are made, the pipes must be straight, the slope must be evenly distributed, and the reserved space must be precise.
This is a summary of PVC pipe installation methods, standard requirements, and precautions. As a new type of urban drainage pipe, PVC pipe is increasingly used in various drainage projects due to its superior performance. In actual use, it is necessary to continuously summarize experience and gradually improve all technical specifications and relevant standards to contribute to the application and promotion of PVC pipes.
