The water pipe φ 25× 1/2 indicates that its outer diameter is 25. The actual corresponding nominal diameter is DN20 (that is, people often say 6 branches). You can buy a 6-cent faucet. You can also buy a faucet for 4 cents (just add a reducer between the pipe and the faucet).
Extended data:
The outer welded aluminum-plastic composite pipe comprises an outer random polypropylene extrusion layer, the inner surface of the random polypropylene extrusion layer is connected with a hot melt adhesive layer, and the inner surface of the hot melt adhesive layer is connected with an aluminum tube layer;
The utility model has the characteristics of high temperature resistance of aluminum-plastic composite pipe, small thermal deformation and reliable hot-melt connection of PP-R pipe, and can be widely used in the fields of cold and hot water pipes and drinking water systems, heating pipes, floors, walls, heating systems, solar heating and refrigeration systems, industrial fluid conveying systems, central air conditioning systems, compressed air pipeline systems and the like.
