AI Summary:
Double wall corrugated pipes combine low weight with mechanical strength, which makes their manufacturing process important for plastic processors and infrastructure product makers. A Double Wall Plastic Corrugator Machine forms pipes with a smooth inner wall and a corrugated outer wall, using corrugator technology to shape the profile and extrusion systems to supply the plastic material. This guide explains the production flow from extrusion to cutting, the plant sections listed by Volcano Flexi Tech Industries, quality factors, applications and selection points for DWC pipe manufacturing equipment.
Double Wall Plastic Corrugator Machine: Definition and Purpose
A Double Wall Plastic Corrugator Machine is a pipe production system that forms pipes with two walls. The inner wall is smooth, and the outer wall is corrugated.
The company information describes its double wall corrugator as a machine developed for corrugated pipes used in high pressure and high impact applications. The inner tube conveys material with minimal loss of friction and pressure, while the outer corrugation adds protective mechanical properties.
It works best as part of an integrated pipe production line.
Double Wall Corrugated Pipe Manufacturing Process: How the Line Works
A DWC Pipe Plant from Volcano Flexi Tech Industries consists of an extruder, die head, corrugator, cooling tank, puller and cutter.
The extruder supplies plastic to the die head. The corrugator forms the double wall structure, and cooling helps the pipe hold its shape and size. The puller draws the pipe through the line, and the cutter cuts it to length.
The listed configuration also notes that the welding junction zone between adjacent pipe surfaces adds strength, depending on the material.
Double Wall Plastic Corrugator Plant: Main Components
A Double Wall Plastic Corrugator plant includes these listed sections:
- Extruder and die head: Supply and shape the plastic material.
- Corrugator: Forms the corrugated outer wall using moulds.
- Tools and die: Mould blocks designed for minimal maintenance at low cost.
- Water tank: Adds cooling through water spray on the pipe’s outside diameter.
- Puller: Grips the pipe with upper and lower rubber belts.
- Cutter and tilting unit: Cuts pipe to length and collects it in order.
The machine specifications include:
| Parameter | Listed Detail |
|---|---|
| Pipe size | 50 mm to 150 mm diameter |
| Corrugator drive | 5 HP, 3 phase 415 ±5 volt gear motor |
| Variable speed drive | 0.5 to 10 metres per minute, with emergency stop |
| Line speed | 3 to 6 metres per minute, depending on pipe size |
| Lubrication | Centralized lubrication system |
| Cooling | Inbuilt cooling channel for chilled water, plus air chiller |
Corrugator Technology for Double Wall Corrugated Pipe Manufacturing
Corrugator technology gives the pipe its profile. The moulds shape the outer corrugation while the inner wall stays smooth, so the finished pipe has both a flow surface and a protective outer structure.
The listed corrugator covers double wall corrugation from 50 mm inside diameter to 150 mm outside diameter, with manual mould replacement for different pipe sizes.
Extruder Machines For Double Wall Corrugated Pipe Production: Role and Function
The extruder supplies the plastic material that the die head shapes before it enters the corrugator.
The listed configuration states that a single extruder with a special die head is used when inner and outer tube materials are similar. Dual extruders with a specific cross die head are used when the materials differ.
Extruder Machines For Double Wall Corrugated production should therefore be chosen according to the pipe material plan.
DWC Extrusion Machine: Support for Pipe Manufacturing
A DWC Extrusion Machine links raw material to the forming process. It feeds the die head, and the die head delivers material into the corrugator, so both stages must suit each other.
A two colour pipe can be made by combining two extruders in one die head through an adapter. Synchronization between puller and extrusion drives supports easier operation and helps reduce material wastage.
Double Wall Corrugated Pipe Making Machine: Influence on Finished Pipe Quality
A Double Wall Corrugated Pipe Making Machine influences quality through consistent forming, controlled speed and proper cooling. Each section affects the next, so quality depends on the whole line.
These machine features contribute to consistent pipe quality:
- The puller maintains pipe uniformity, with speed controlled against corrugator line speed.
- The cooling tank helps maintain shape and size.
- The air chiller supports better finish and output.
- Cutter clamping force is adjustable to suit wall thickness and diameter.
Review these quality points during machine evaluation:
- Wall thickness consistency: Steady material supply and controlled pulling speed support uniform walls.
- Inner wall smoothness: The smooth inner wall is what gives the pipe its flow surface.
- Corrugation profile accuracy: Well designed moulds shape the outer corrugation.
- Cooling stability: Water spray and chilled water cooling help the pipe keep its shape and size.
Double Wall Corrugated Pipes: Key Applications
Company information lists indoor, outdoor and underground uses, including sanitary sewer and drainage systems. Applications by sector:
- Agriculture: Field drainage, irrigation and greenhouse drainage.
- Automotive: Air conditioning ducts, heater ducts, radiators and hoses.
- Construction: Bridge and building cable ducts, conduits and ventilation ducts.
Other listed uses include civil engineering, drip irrigation and biogas plant media.
Double Wall Corrugated Pipe Plant: Setup Considerations
A Double Wall Corrugated Pipe Plant should be planned as a full line rather than a single machine. Key points to review:
- Product plan: Pipe size, material and colour needs decide the extruder arrangement, die head and moulds.
- Line sections: Extrusion, corrugation, cooling, pulling and cutting each need floor space, water supply and electrical provision.
- Manufacturing goals: The listed line speed is 3 to 6 metres per minute, depending on pipe size.
DWC Pipe Manufacturing Solution: How to Select the Right One
Use these steps when evaluating a solution:
- Compare requirements: The listed range for the double wall machine is 50 mm to 150 mm pipe size, and the company also lists a 500mm ID double wall plastic corrugator pipe plant as a separate product.
- Review the complete line: Check how the extruder, die head, corrugator, cooling, puller and cutter fit together.
- Hold a technical discussion: Volcano Flexi Tech Industries offers double wall corrugated pipe manufacturing solutions, and a direct enquiry helps confirm suitability for your material, size and output plans.
About Volcano Flexi Tech Industries

Double Wall Plastic Corrugator Machine Selection: Conclusion
Understanding corrugator technology helps manufacturers see how a smooth inner wall and a corrugated outer wall are formed in one continuous process. The extrusion system supplies the material, the die head and corrugator shape it, and cooling, pulling and cutting complete the pipe. Selecting suitable DWC machinery therefore requires checking each option against your own requirements. Evaluating complete DWC pipe manufacturing solutions and discussing them with machinery manufacturers helps buyers select a suitable configuration based on pipe size, material requirements and production goals.
