200-450mm PVC Pipe Extrusion Line

1. PVC Material Mixing System

Stable PVC compound preparation is important for large diameter pipe surface quality and extrusion consistency. The mixer can be matched with loader, storage and feeding system according to factory automation level.

• Hot and cold mixing for PVC powder formulation
• Supports stable feeding before extrusion
• Useful for drainage, water supply and sewage pipe formulations

2. Conical Twin Screw Extruder

The extruder is selected around pipe diameter, wall thickness and target output. For 200-450mm pipes, Winsoar pays attention to plasticizing stability, melt pressure, screw configuration and electrical control matching.

• Matched with PVC/UPVC powder compound
• Extruder model selected according to output target
• Control cabinet and screw design customized by project

3. PVC Pipe Die Head and Mould

The pipe die head and mould are key for diameter accuracy, wall thickness distribution and pipe surface condition. For larger pipes, mould selection and calibration matching directly affect stable production.

• Mould sets prepared according to target pipe diameters
• Calibration sleeves matched with pipe outside diameter
• Important for roundness and wall thickness control

4. Vacuum Calibration Tank

The vacuum tank shapes the extruded pipe and helps keep stable outside diameter. For 200-450mm pipes, tank structure, vacuum control and water circulation must be matched with pipe size and production speed.

• Vacuum sizing for pipe diameter accuracy
• Water circulation and tank length customized by line speed
• Supports stable pipe shape before spray cooling

5. Spray Cooling Tank

Large diameter PVC pipes need enough cooling length to reduce deformation and keep stable dimensions. A spray cooling tank can be configured after vacuum sizing for continuous production.

• Additional cooling for medium and large diameter pipes
• Spray system matched with pipe output and wall thickness
• Helps improve line stability during continuous production

6. Haul-off Machine

The haul-off machine pulls larger PVC pipes at a synchronized speed. For 200-450mm pipe production, traction structure and clamping stability are more important than on small-diameter lines.

• Stable traction for heavier PVC pipes
• Speed synchronized with extrusion and cutting
• Structure selected according to pipe diameter and weight

7. Automatic Pipe Cutting Machine

The cutter is configured for larger pipe diameter and required cutting length. Depending on the pipe standard, it can support automatic length measurement, synchronized cutting and dust collection.

• Automatic cutting length control
• Suitable for medium and large diameter PVC pipes
• Cutting style and dust collection customized by project

8. Optional Pipe Belling Machine

For drainage, sewage and water supply pipe projects, the belling machine forms socket ends after cutting. Socket type and heating method should be confirmed according to local pipe standard.

• Socket forming for PVC pipe connection
• Recommended for drainage, sewage and water supply pipe projects
• Socket type selected according to pipe standard

Factory Workshop and Line Assembly

For a 200-450mm PVC pipe project, the machine layout and downstream size should be checked before shipment. Workshop assembly helps confirm extruder, tank, haul-off, cutter and belling machine coordination.

• Workshop assembly for extruder and downstream equipment
• Electrical cabinet and mechanical checking before delivery
• Project layout discussion for overseas buyers

Machine Parts Checking Before Delivery

Large pipe production projects need careful checking of moulds, calibration parts, electrical elements and spare parts. Winsoar prepares the parts list according to the final line configuration.

• Mould and calibration part checking
• Electrical and mechanical parts review
• Spare parts preparation according to project scope

Export Packaging for Overseas Shipment

Export packaging is arranged according to machine size, tank length and shipment method. Main equipment is protected with wrapping materials, while moulds, electrical parts and accessories can be packed in wooden cases.

• Protective wrapping for machine body and control cabinet
• Wooden case packing for moulds, accessories and spare parts
• Packaging plan prepared according to container loading requirement

Container Loading and Shipping Support

For medium and large diameter PVC pipe lines, container loading should consider equipment length, tank protection and unloading convenience. Winsoar can provide loading photos and shipment support for overseas customers.

• Container loading plan based on equipment dimensions
• Photos can be provided during loading and shipment preparation
• Suitable for complete PVC pipe production line export projects

Exhibition Booth and Customer Communication

Winsoar also communicates with overseas buyers through plastic machinery exhibitions. Exhibition discussion helps buyers compare PVC pipe extrusion line configuration, pipe application and investment plans more directly.

• Face-to-face communication for PVC pipe machine projects
• Project discussion for drainage, water supply and sewage pipe production
• Useful for buyers comparing machine configuration and factory planning

Project Meeting and Technical Confirmation

Before quotation, buyers can discuss pipe sample, wall thickness, socket type, local pipe standard, output target and factory layout. These details help Winsoar avoid under-configured or over-configured solutions.

• Pipe diameter and wall thickness confirmation
• Discussion about local standards and pipe applications
• Quotation prepared according to real production requirements

It is a complete PVC pipe production line used to produce medium and large diameter PVC or UPVC pipes from 200mm to 450mm, including extrusion, sizing, cooling, hauling, cutting and optional belling.

Yes. The line can produce different diameters by changing pipe moulds, calibration sleeves and relevant settings. The practical range should be confirmed according to extruder output and downstream configuration.

Yes. The 200-450mm range is commonly used for municipal drainage, sewage, water supply, irrigation and larger industrial pipe applications.

Choose according to your main pipe sizes and long-term order plan. If 200mm to 450mm pipes are your main products, this page is the more focused configuration range. If your main products are smaller or larger, Winsoar can recommend another line range.
