Heat-Insulating HDPE Pipe Machine\Pre-Insulated Pipe Making Machine
There's two different method to manufacture the insualtion pipe:
Diameter below 426mm, we provide
one step insulating machinewhich is produce HDPE jacket ,thread steel pipe and inject foam together;
Diameter bigger than 426mm, we provide
two steps Extrusion Line which is produce HDPE insulation jacket prodcution line first, then inject foam between HDPE jacket and steel pipe;
One Step Insulation Pipe machine
This one step technology is to cover the steel tube surface with insulation layer& anti-corrosion layer at the same time, thus forms insulating& anti-corrosion layer of the pepeline, which is pioneer way in China, Compred wich other methods, it features continuous operation, high efficiency, low cost, energy saving, labor saving, environment pollution-free and so on. Progress second prize, several technology update to the advanced international lever. After updating technology, it has reached internation advanced lever.
The outer jacket can be
yellow color and
black color.
Technical features of Insulation pipe machine
1. can be operated continuously, high production efficiency, low cost, energy saving
2. automatic deviation adjusting machine, high exactness, steady working, effective correction
3. the whole line all conveyed by rubber wheel, avoid damage to anti-corrosion layer of steel tube
4. casing layer stick with foam layer, foam layer stick with anti-corrosion layer, anti-corrosion layer firmly stick with steel tube.
5,Foming machine online foaming;
6,Pushing machine push the steel into the clad die head&Mould easily;
Specification table of insulation pipe: The thickness of foaming layer and casing can be desinged
