Ductile iron pipes are related -
PPPE pipe under the condition of equal pressure, PPPE tube wall thickness of pipes and pipe fittings than pp-r pipe (
Ⅲ type polypropylene, namely random copolymerization polypropylene)
The wall thickness is smaller, and the diameter, the size, the more so PPPE pipe price is pp-r pipe is low.
According to the measuring PPPE pipe engineering cost about 80% less than of pp-r pipe.
Of the specifications of the currently available for DN15 - ((
Five, the sizes is the same as the hot dip galvanized steel pipe PPPE pp-r -c or PP and HDPE as main materials, synthetic materials such as a certain amount of chemical fertilizer, after extrusion forming of plastic tubing.
It is reported that [
, this kind of pipe wide applicable temperature range (
, high pressure,
Nominal pressure of 20 mpa)
, not only can like PE pipe, PB, modified polypropylene (
Such pipe for hot melt connection (
Have dedicated PPPE tube supporting hot-melt pipe)
, but also like hot dip galvanized steel pipe tool set with ordinary set of silk silk at the scene, using pipe threaded connection with internal thread.
