Feasibility of Reinforced Thermoplastic Pipe for High Pressure Long distance Hydrogen Transmission Pipeline

In the modern vigorous development of global oil and natural gas, a major technological breakthrough in high-pressure long-distance pipeline transportation is the continuous development and expansion of applications of reinforced thermoplastic pipes, which show unique advantages, especially in parti......

Is the extruder screw often worn? There are these main reasons!

Screw extruder is the core equipment of plastic forming and blending modification. In the actual production process of blending modification, the screw of the extruder is in a harsh high pressure and high temperature environment, and bears huge friction and shear force. Due to the special working......

Performance Characteristics of Various PVC-U Pipes

With the enhancement of people's awareness of environmental protection, the requirements for building water supply and drainage are higher and higher, and various new structural PVC-U pipes came into being. Its functions and characteristics are different.

Application Prospect of Plastic Pipe Extrusion Equipment

The production process of plastic pipe extrusion should be selected according to the type and size of plastic pipe. Generally, plastic extruders are used to extrude products. However, plastic materials and types of plastic pipes are different, so the principle of molding in production is different. ......

What to do when there is no vacuum in the production of PE three-layer co-extrusion pipe equipment

PE three-layer co-extrusion pipe equipment production line is a production and manufacturing line of plastic pipes using vacuum sizing technology. However, if the technology is not mature, the processing is rough, and the process is not refined, some unexpected failures may occur, such as no vacuum.......

Deceleration principle of twin-screw extruder

In most extruders, the screw speed changes by adjusting the motor speed. The drive motor usually rotates at full speed of about 1750 rpm, which is too fast for an extruder screw. If it rotates at such a fast speed, too much friction heat will be generated, and the retention time of plastic is too sh......
