HDPE Jacket Pre-Insulated Oil Pipe Extruder Machinery with Polyurethane Foam

Product Description

Pre-insulated pipe production line with HDPE Black/Yellow Shell and polyurethane foam.
HDPE Casing Pipe Making Machine
polyurethane foaming Machine
Thermal insulating pipe is widely used in central heating, oil, nature gas and other industrial area.



Type 1: Two Step Pre-insulated Pipe Making Machine
Brand : Qingdao Sincere Machinery
 
Two Step Pre-insulated Pipe Making Machine
Isolate heat layer and anti-corrosion layer are wrapped on steel pipe at the same time, continuous production, high efficiency and low cost.
Machine feature: low cost, without vacuum calibration tank, inner pressure produce method;
In-line ball blast de-rust, in-line painting and antirust treatment.
Diameter range: Φ48-Φ1800mm.
This set is mainly used to produce the big size PE heat preservation pipe. Its product is mainly used in the outer layer of heating pipe line, the middle layer is polyurethane foaming layer and the inner layer is steel tube. 
It can also produce water supply pipe and drain pipe by adding the vacuum calibration tank and cooling tank. 
This set is composed of extruder, die and mould, cooling water sink, haul off machine, clipping pipe machine, bracket, support frame and electric controlling pats, etc.

Technology flow:HDPE two step method is produce the HDPE casing in first step, then thread pipe inside the casing and foaming in the middle of it.

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.
5,Foming machine online foaming;
6,Pushing machine push the steel into the clad die head&Mould easily;
