PU Polyurethane Foam Pipeline Production Equipment
Pipelines are commonly used equipment in industrial production and are widely used in petroleum, natural gas, refining, chemical, light industry and other industries. As a pipeline insulation material, PU rigid foam is widely used in pipeline insulation of crude oil transportation pipelines and petrochemical industries, and has successfully replaced materials with high water absorption such as perlite.
Product Features of High Pressure PU Machine:
1.Adopting three layer storage tank, stainless steel liner, sandwich type heating, outer wrapped with insulation layer, temperature adjustable, safe and energy saving;
2.Adding material sample test system, which can be switched freely without affecting normal production, saves time and material;
3.Low speed high precision metering pump, accurate ratio, random error within ±0.5%;
4.Material flow rate and presure adjusted by converter motor with variable frequency regulation, high accuracy, simple and rapid ration adjusting;
5.High-performance mixed device, accurately synchronous materials output, even mixture. New leakproof structure, cold water cycle interface reserved to ensure no blockage during long downtime;
6.Adopting PLC and touch screen man-machine interface to control the injection, automatic cleaning and air flush, stable performance, high operability, automatically distinguish, diagnose and alarm abnormal situation, display abnormal factors.
Detailed Images
Material tank
This is the storage tank A and B tank of the polyurethane high pressure machine. Polyurethane and Isocyanate raw materials are separately installed.
Material of the tank: SS304
Size of feeding flange: φ150
Capacity: 250L

Mixing head
The mixing head adopts floating mechanical seals, and its high shear mixing screw head, which can mix two materials (Polyurethane and Isocyanate) with better performance.The raw materials are stirred at high speed in the mixing chamber by stirring blades to achieve a mixing effect, so that the liquid is uniformly sprayed to form a desired product.
Electrical control system
1. Fully controlled by SCM (Single Chip Microcomputer).
2. Using PCL touch screen computer. Temperature,pressure, revolving speed display system.
3. Alarm function with acoustic warning.
