1.Good connection: using hot melting, the connecting area is stiffer than the pipe itself. It's easier for connecting with flange
2.Low temperature impact: safe using temperature is between -60° and 60°. Pipes and fittings can be done outsider in winter.
3.Good chemical corrosion resistance. Chemicals within soil can not be threat to pipes.
4.Good aging resistance, long service life, ultraviolet resistance, economical.
5.Good water resistance: smooth inner and outsider which can make water faster than normal with low noise
6.Lighter than steel pipe. Only one forth of steel pipe.
