Several matters needing attention in the use of PVC pipe for farmland irrigation
1. Farmland irrigation pipes shall be connected with special glue and shaken well before use.
2.PVC pipes and sockets must be cleaned. The smaller the gap between the grooves, the easier it is to polish the joints with emery cloth or saw blades. Spread a thin layer of glue evenly over the trough. Brush the outside of the socket twice with glue. When the glue has dried for 40-60 seconds, insert it. The drying time of glue increases and decreases with climate change.
3. Do not touch water during bonding. Once the pipe is in place, it must be placed in the trench. Backfill the joints after 24 hours of drying. During backfilling, pipes should be filled with sand and seams to allow for large-scale backfilling.
4. When PVC pipe is connected with steel pipe, the steel pipe joint must be clean and bonded. The PVC pipe is heated to soften (but does not burn out) and then placed on the steel pipe for cooling.
