Multi-layer pipe is new heat
insulation material. It has advantage of
low cost, anti-corrosion, long life and better insulation effect.
The
multi-layer and compact structure avoid leakage problem happen
and low the exhaust of energy. Specially, the outer layer is
spiral, this kind of design will strong enough and bury under
earth deeply. The length
can be choosing.
Old version of this kind of pipe ,inner one is metal not
good at anti-
corrosion and the lengh only can be ***0mm ,it is hard to adjust
.The
new material also can lose cost because of low demand of
foaming
material This production line adopts two or three
extruders co-extrusion crafts, uses PP-RPPas main material, and
glass fiber in the middle layer. This glass fiber intensified
pipe has the advantages of high tenacity and strength, can
withstand high inner and outer pressure; The pipes also overcomes
the weak points that the pipe is easy to go bending and
deforming.
Our company has successfully enlarged the worldwide markets for
this production line, such as Pakistan, Bangladesh, etc. And in
China, this production line are warmly welcomed by more and more
plastic manufacturers, the pipe market is becoming larger and
larger.
