Manufacturing Process
Step 1: Order and Design
Determine the specifications of the PPH pipe (such as outer diameter, wall thickness, and pressure rating) based on customer requirements, and complete the product structural design and production process planning.
Step 2: Raw Material Preparation & Molding
Select high-quality PPH raw material (β-crystalline polypropylene). After drying, produce the PPH pipe using an extrusion molding process to ensure material uniformity and dimensional stability.
Step 3: Machining
Perform cutting, end face finishing, and necessary dimensional machining on the molded PPH pipe to meet installation and connection requirements.
Step 4: Assembly
Perform appropriate connections on the PPH pipe (such as heat fusion or flange connections) according to application requirements, and pre-assemble with related fittings.
Step 5: Testing & Quality Assurance
The PPH pipes undergo pressure testing, dimensional inspection, and visual inspection to ensure compliance with industry standards (such as DIN, ISO, etc.) and customer requirements.
Step 6: Finishing, Packaging and Shipment
The products are cleaned, protected with packaging (to prevent dust and scratches), sorted, packed, and then shipped.
