Production process of pe rod
Select HDPE or UHMWPE pellets, drying treatment (temperature ≤ 80 ℃) to remove moisture.
Heating and plasticizing by twin-screw extruder, temperature is controlled in stages (160℃→220℃), and the mold is designed to ensure smooth flow path.
Vacuum sizing tank to control the outer diameter, spray water cooling (water temperature 10~25℃) to reduce internal stress.
The traction speed is synchronized with the extrusion, and the precision cutting equipment ensures that the length error is ≤1mm.
On-line testing of wall thickness, outer diameter, sampling for hydrostatic test (such as GB/T 6111 standard).
Advantages of pe rod
Resistant to most acid and alkali corrosion (except strong oxidizers), suitable for chemical industry, sewage treatment and other environments.
Abrasion resistance 4 times that of steel, high impact resistance (elongation at break >500%), excellent low temperature toughness.
Low density, convenient handling; non-toxic and harmless, in line with food grade and medical standards.
Support electric welding, heat welding and other connection methods, customized size and color.
Application of pe rod
- Seals, sliding profiles: used for wear-resistant parts of mechanical equipment (e.g. cutting plates, bearings).
- Chemical piping: corrosion-resistant transportation piping (gas, sewage).
- Medical appliances: Surgical instrument parts, catheters (e.g. PE vascular cannulae).
- Irrigation system: weather-resistant, suitable for agricultural drip irrigation.
- Water supply and drainage pipes: smooth inner wall, high circulation efficiency.
- Insulation material: Bakelite board, cable protection sleeve.
In Summary
With its corrosion resistance, high abrasion resistance, light weight and other characteristics, PE rod has become an ideal material in many fields. The production process focuses on precision control, and the product parameters can be flexibly adapted to the demand, which is widely used in industrial, medical, agricultural and other fields.
Frequently Asked Questions (FAQ)
What types of materials are PE rods made of?
PE rods are primarily made from High Density Polyethylene (HDPE) or Ultra High Molecular Weight Polyethylene (UHMWPE), depending on the specific application requirements.
What is the temperature resistance range of a PE rod?
PE rods exhibit excellent temperature performance with a working temperature range of -70℃ to 100℃.
How chemically resistant are PE rods?
