Nowadays, 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.

Advantages |
Disadvantages |
RTP pipe |
|
The pressure of Aramid fiber reinforced pipe is up to 9-14Mpa.
The explode pressure can be 40Mpa.
Currently the RTP pipe is mainly used in
industrial field,especially at oil exploitation
area, such as Middle East hot desert, the
cold Siberian area and sea oil well. |
Price of RTP pipe is relatively
higher |
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 use 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,cannotbe
recycled for reuse |
PB pipe |
|
Good heat resistance, good tensile
and compressivestrength,
good impact resistance, low creep
and high flexibility |
Price of PB material is
relatively higher |
CPVC pipe |
|
Has the best temperature resistance
among thesepipes,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 |
