The material tube is generally made of plastic resin as a raw material, added with stabilizers, lubricants, etc., and is extruded in a tube making machine by a plastic method. Because it has the characteristics of light weight, corrosion resistance, beautiful appearance, no bad odor, easy processing, and convenient construction, it has been increasingly used in construction projects. Mainly used as piping for water supply system of housing construction, drainage, exhaust and sewage sanitary pipes, underground drainage pipe system, rainwater pipe and threading pipe for electric wire installation.
There are two major types of plastic pipes: thermoplastic pipes and thermosetting plastic pipes. The main resins used in thermoplastic pipes are polyvinyl chloride resin (PVC), polyethylene resin (PE), polypropylene resin (PP), polystyrene resin (PS), acrylonitrile-butadiene-styrene resin (ABS ), Polybutene resin (PB), etc .; the main resins used in thermosetting plastics are unsaturated polyester resins, epoxy resins, furan resins, phenolic resins, etc.
PVC pipe
Has good tensile and compressive strength, but it is not as flexible as other plastic pipes, and has excellent corrosion resistance. The price is the cheapest among all types of plastic pipes, but it is more brittle at low temperatures.
Adhesive, socket rubber ring connection, flange thread connection
Used in residential life, industrial and mining, agricultural water supply and drainage, irrigation, gas supply, exhaust pipes, electrical conduit, rainwater pipes, industrial anticorrosion pipes, etc.
CPVC pipe
Outstanding heat resistance, thermal deformation temperature is 100 ℃, excellent chemical resistance
Bonding, flange thread connection
Hot water pipe
PE pipe
Light weight, good toughness, good low temperature resistance, non-toxic, cheaper price, high impact strength, but low compressive and tensile strength
Hot melt welding, flange thread connection
Drinking water pipe, rain water pipe, gas pipe, industrial corrosion-resistant pipe
PP pipe
Good corrosion resistance, good strength, high surface hardness, surface finish, and high temperature resistance
Hot melt welding, flange thread connection
Chemical sewage, seawater, oil and irrigation pipes for indoor concrete floors as heating pipes for heating systems
