Type 2: One Step Pre-insulated Pipe Making Machine
Brand : Qingdao Sincere Machinery
One Step Pre-insulated Pipe Making 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 casing can be yellow color and black color.
Technical features of pre-insulated pipe making 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.
