Steel Pipe VS Plastic Pipe
Galvanized steel pipe
Due to its low price, superior performance, good fire performance and long service life, galvanized steel pipes are widely used in fire water supply systems, especially in automatic sprinkler systems, while plastic pipes (small pressure) are not suitable for fire water supply systems. Application.
Copper tube
The most advantageous metal pipe is copper pipe. The copper pipe is used for a long time, and has many advantages. The pipe and pipe fittings are complete, the interface modes are various, and many applications are in the hot water pipe.
Cast iron pipe
Compared with steel pipes, water-supply cast iron pipes are not easy to corrode, low in cost and good in durability, and are suitable for buried laying. The disadvantages are brittleness, heavy weight, and small length. The connection method is generally a socket connection. Clamp-type cast iron drain pipe is a new type of construction drainage pipe. It has entered the international market since the 1960s. After decades of promotion and application, this pipe has been widely recognized internationally. This type of pipe has many advantages over traditional cast-in cast iron drains and is a replacement.
The plastic pipe is a product obtained by melt molding of a synthetic resin and an additive. Additives include plasticizers, stabilizers, fillers, lubricants, colorants, UV absorbers, modifiers, and the like. Commonly used plastic pipes are: rigid polyvinyl chloride pipe (PVC-U), high density polyethylene pipe (PE-HD), crosslinked polyethylene pipe (PE-X), random copolymer polypropylene pipe (PP-R), Polybutene tube (PB), engineering plastic acrylonitrile-butadiene-styrene copolymer (ABS), etc.
The main advantages of the plastic pipe are small thermal conductivity, low thermal conductivity, thermal insulation, and good energy saving effect. Compared with metal pipes, the density is small, the material is light, transportation, installation is convenient, flexible, simple, and easy to maintain.
The disadvantages of plastic pipes are poor mechanical properties, poor impact resistance, poor rigidity and poor straightness, so the density of pipe clamps and hangers is high. Poor flame retardancy, most plastic products are flammable and thermally decomposed during combustion, releasing toxic gases and fumes.
