I. Introduction to the super-high tube The super-high tube uses a special extruder and a specially designed mold to continuously extrude the ultra-high molecular weight polyethylene powder. Superior performance of the super-high tube, wear resistance, low temperature resistance, corrosion resistance, self lubrication, impact resistance in all plastics is the highest value, wear resistance is better than PTFE, nylon, carbon steel and other materials, long-term Working at -169 to +80°C is called "amazing" engineering plastics!
Super-high-tech technology has gradually matured in China. More and more projects have adopted this kind of pipeline and become a new type of thermoplastic engineering plastics with moderately-priced properties. It almost concentrates the advantages of various plastics, and resists impact and wear. Lubricant, corrosion resistance, low temperature resistance, hygienic non-toxicity, non-adhesion, non-absorbent and other comprehensive properties, is an ideal pipe, can be used for a variety of highly corrosive, highly abrasive liquid or solid-liquid mixture delivery, Such as various acid, alkali, crude oil, tailings, mud, coal slurry and power plant ash, slag and so on. Compared with seamless steel tubes, the super high tubes have significant advantages, increase the service life, and can increase the service life several times or even dozens of times under strong corrosive and high wear conditions; due to the non-tackiness of the inner wall of such pipes ( Non-fouling) Small coefficient of friction and friction, can reduce the delivery pressure or reduce the diameter of the delivery pipe. It is of great significance for long-distance transportation. Since the thermal conductivity of this pipe is more than 10,000 times smaller than steel, the transmission line can be greatly reduced. The cost of insulation is of great significance for the transport of crude oil and other materials in cold regions and in winter.
Second, super-manufacturing process outlined:
1: The superpipe is made of ultra high molecular weight polyethylene powder plus a small amount of paraffin wax and carbon black extruded through an extruder at high temperature.
2: Different diameters and thicknesses of ultra-high tubes require different molds.
3: The length of the super tube can be arbitrarily produced according to the user's needs.
4: The color of the supertube can be added to the raw material in accordance with the user's needs.
Third, super executive performance:
(1) Wear resistance ranks first in plastics, which is 7-10 times that of carbon steel and stainless steel;
(2) The first column of impact strength plastics, 2 times for PC and 5 times for ABS (3) Self-lubrication, anti-adhesion, non-fouling, low coefficient of friction, comparable to PTFE;
(4) The impact energy absorption value is the highest in all plastics, and it has a sound dampening property;
(5) Good chemical stability, resistance to various corrosive media and organic media in a range of temperatures and concentrations;
(6) excellent low temperature resistance, still ductile at -269 °C;
(7) Excellent resistance to internal pressure, resistance to environmental stress cracking, and resistance to rapid cracking;
(8) Hygienic, non-toxic, accessible to food and drugs.
