1、建筑设备给排水（1 、 construction equipment water supply and drainage） Brass has strong thermal conductivity and excellent toughness. The connection: welding, sleeve type, flange connection The specifications are usually smaller diameter. The length of 3 ~ 6M The category: copper, brass The application: copper is mainly used for oxygen, air conditioning, water purification equipment, pharmaceutical pipeline, water supply, water pipe is especially suitable for high-grade high-rise buildings; can be used for building water supply of small diameter stainless steel pipe. 4, non metal pipeline 1 reinforced concrete pipe For the water supply pressure tube, suitable for underground The characteristics of corrosion resistance, good durability, high strength, anti permeability, low price, large diameter (400 ~ 2000mm), but the heavy weight, inconvenient transportation. 2 asbestos cement pipe The glass with silk It features: smooth surface, corrosion resistance, long service life, easy processing, low price, crisp, low strength, poor impact resistance, easy to damage. The connection: ring, rubber gasket. 3 plastic pipe 1 species: including polyvinyl chloride (PVC) pipe, polyethylene (PE) pipe, cross-linked polyethylene (PEX) pipe, polypropylene (PP - R), polybutylene (PB) and so on. The characteristics of corrosion resistance, easy processing, light weight, smooth wall, water and health; but the poor heat resistance, small diameter, UV resistance difference, The connection: adhesive, hot melt connection, welding connection, flange connection or special pipe connection. 4 glass fiber reinforced plastic composite pipe The glass cloth coated with epoxy resin, adhesive layer made of. It features: corrosion resistance, pressure resistance, light weight, smooth surface, large diameter The connection: socket and flange connection. Six, building water supply engineering 1, function The water supply pipe into the room from the outside, and to meet the user to the quality and quantity of wate
