Summary
The production of PE (polyethylene) pipes and fittings involves several key steps, each crucial to ensuring the quality and durability of the final product.
The production of PE (polyethylene) pipes and fittings involves several key steps, each crucial to ensuring the quality and durability of the final product.
1. Material Preparation
The primary raw material for PE pipes and fittings is polyethylene (PE) resin particles.
Before production, the PE resin particles undergo screening and drying to ensure material quality and stability.
2. Extrusion Molding
Extrusion is the core process for PE pipe production.
Dry-treated PE particles are placed in the hopper of an extruder.
The rotating screw heats and melts the PE particles.
The molten PE material is then extruded through a die head, forming long cylindrical pipes or fittings.
3. Cooling and Solidification
After extrusion, the PE pipes and fittings need cooling and solidification.
Water bath cooling is commonly used, where the extruded pipes and fittings are immersed in a cooling water tank.
Cooling gradually solidifies the pipes and fittings, enhancing their structural strength and stability.
4. Cutting and Packaging
Cooled and solidified PE pipes and fittings are cut to specified lengths.
The cut pipes and fittings are categorized, stacked, and packaged for transportation and storage.
5. Quality Inspection
Strict quality inspections are conducted during production.
Inspections include visual checks, dimensional measurements, and physical performance tests.
Only PE pipes and fittings that pass quality inspection are ready for sale.
6. Application
PE pipes and fittings produced through this process find applications in various fields:
Construction: Used for water supply, drainage, and HVAC systems.
Agriculture: Serve irrigation and drainage purposes.
Chemical Industry: Transport chemicals and liquids.
Conclusion
The production process ensures the quality and safety of PE pipes and fittings, contributing significantly to societal development and progress.
