Advantages and disadvantages of several common plastic pipes
Nowadavs, plastic pipe has been widely applied in many fields: convey liquid, gas and heat, cable protection, irrigation and other applications. There are many plastic pipes made by different plastic materials. Below are advantages and disadvantages of several common plastic pipes for comparison.
Plastic Pipes |
Advantages |
Disadvantages |
HDPE pipe |
Good toughness, good fatigue strength, good temperature resistance, light weight, good flexibility and good impact resistance |
Need electrical welding , mechanical connections, large fittings |
PVC/UPVC pipe |
Strong corrosion resistance, ease of bonding, cheap, hard texture |
UPVC monomer and additives may ooze out of pipe, not suitable for hot water transport,require high bonding technology for joints and longer curing time |
PPR pipe |
Good temperature resistance |
Under same pressure and medium temperature, it has the thickest wall. |
PEX pipe |
Good heat resistance, good creep resistance |
Can only be connected by metal parts, can not be recycled for reuse |
PB pipe |
Good heat resistance, good tensile and compressive strength, good impact resistance, low creep and high flexibility |
Price of PB material is relatively higher |
CPVC pipe |
Has the best temperature resistance among these pipes, good anti-aging performance |
Price of CPVC material is relatively higher |
PEX-Al-PEX pipe |
Easy bending and forming, completely eliminating oxygen permeation and small linear expansion coefficient |
Non-uniform wall thickness |
ABS pipe |
High strength and impact resistance |
Poor UV-resistance and longer adhesive curing time |
