Gain Practical Knowledge About Multilayer HDPE and PP Pipe Extrusion
Learn how 3- and 5-layer pipe structures, coextrusion die heads, raw material selection, layer adhesion, weldability and delamination risk influence the quality and stability of HDPE and PP pipe production.
This course is Part 3 of the Plastic Pipe Extrusion series. It focuses on the extrusion of 3- and 5-layer HDPE and PP pipes and helps participants understand how different layers work together in multilayer pipe structures such as ABA, ABC, ABCBA and other configurations.
Who is this course for?
This course is designed for:
- pipe extrusion line operators,
- operators working with multilayer pipe extrusion lines,
- process technologists,
- shift leaders and production managers,
- quality control staff,
- in-house laboratory staff,
- employees responsible for new product implementation,
- employees working with coextrusion, recycled layers, barrier layers, protective layers or identification stripes,
- companies producing or planning to produce 3- and 5-layer HDPE and PP pipes.
What will you learn?
The course covers:
- 3- and 5-layer HDPE and PP pipe structures,
- ABA, ABC, ABCBA and other multilayer layouts,
- function of individual pipe layers,
- coextrusion die heads for multilayer pipes,
- flow of several melt streams in pipe coextrusion,
- raw material selection for individual layers,
- compatibility of HDPE, PP and other materials used in multilayer pipe structures,
- identification stripes, marking and functional layers,
- influence of layer structure on pipe weldability,
- adhesion between layers,
- delamination risk and prevention,
- practical factors influencing the stability of multilayer pipe production.
What will you gain after completing the course?
After completing this course, you will:
- better understand how 3- and 5-layer HDPE and PP pipes are built,
- recognize the function of individual layers in multilayer pipe structures,
- understand how coextrusion die heads influence layer uniformity,
- better assess raw material selection for different layers,
- understand why material compatibility is important,
- recognize problems related to poor adhesion between layers,
- identify early risks of delamination,
- better understand how multilayer structure may influence pipe weldability,
- improve communication between operators, technologists and quality control,
- build a stronger foundation for further training in pipe quality control and problem solving.
