Double Wall PLASTIC CORRUGATOR MACHINE
DOUBLE WALL PLASTIC CORRUGATOR PIPE PLANT (DWC PIPE PLANT)
To strengthen corrugated pipe lor use in high pressure & high impact applications, Volcano have developed a mile stone double wall Corrugator of marvelously crafted article of plastic technology.
For similar material of inner & outer tube, single extruder is used with special die head, while for non-similar material of inner & outer tube, duel extruders with specific cross die head is used.
Here Inner tube protects & conveys material at minimum loss of friction & pressure, while outer corrugation adds protective mechanical properties.
Depending on material, welding junction zone of adjacent pipe surfaces gives additional strength like as of spiral-breaded design.

DWC PIPE
Advantage of Double wall Corrugated pipe is cost effective as it outer wall is corrugated make that light in weight with excellent high performance engineering mechanical properties, impact resistance, crush resistance. compression strength with high ring stiffness.
Additional inner wall provide smooth surface which provide high flow efficiency due to less friction. It has got good corrosion resistance as well as easy inserting application e.g. Cable. Due to excellent junction method it has become leakage proof.It is easy to cut,handle & deliver for drain system.
It can be made from a wide range of blow-moldable or vacuum-formable thermoplastic materials including PE, HDPE etc.
These pipes are used in various indoor, outdoor, underground applications like sanitary sewer system and other drainage application.
- Agriculture : Field drainage systems, Irrigation, Greenhouse drainage, land irrigation.
- Automotive : Heater/defrosting air conditioning ducts, radiators & other hoses.
- Construction : ln Bridge & Building Cable ducts & conduits, heating & water pipe insulation ventilation air conditioning ducts, central vacuum duct work & hoses
Frequently Asked Questions
Can this line make underground power and telecom ducts as a cable protection corrugated pipe extrusion line?
Yes. DWC pipe is widely used as duct for power and optical-fibre cables. The corrugated outer wall carries the soil load, and the smooth inner wall lets cables be pulled through easily. Our 40–250 mm vacuum DWC models are built specifically for cable conduit.
Which DWC pipe making machine model should I choose?
| Model | Pipe sizes | Drive |
|---|---|---|
| Vacuum DWC 40-50-63 | 40, 50, 63 mm | 5 HP |
| Vacuum DWC 40-120 | 40–120 mm | 7.5 HP |
| Vacuum DWC 75-200 | 75–200 mm | 10 HP |
Why does chain length matter on double wall corrugator machines?
Chain length decides how long the pipe stays in the cooled mould blocks. A longer chain gives the corrugation more time to set, so the line can run faster. Each model comes with two options: 3051/6102 mm (40-50-63), 4000/6000 mm (40-120) and 4550/6000 mm (75-200). Choose the longer chain when output matters most, or the shorter one to save floor space.
What does “vacuum” do in a double wall corrugated pipe extrusion line?
The mould blocks have channels connected to a vacuum system. As the outer layer leaves the die head, the vacuum pulls it tight against the cavity, so it takes the exact corrugation shape. The result is sharper, more uniform corrugations and more consistent ring stiffness.
Can I use recycled material on an extrusion line for DWC pipe?
Yes. With two extruders, virgin material can go to the inner wall, where smoothness and flow matter, and recycled granules to the outer wall. This lowers raw-material cost. Check the recycled-content limits in the standard or tender you are supplying.
How is weight per metre controlled on a double wall corrugated pipe making machine?
Weight comes from balancing extruder output against line speed. More output at the same speed gives a heavier, stiffer pipe. Higher speed at the same output gives a lighter one. Once set, the synchronised panel holds that ratio steady for the whole run.
What are the moulds and die pins made of in double wall corrugated plastic pipe making machines?
Cavity blocks are precision-machined from special-grade steel and then plated. Die pins are hardened steel with hard-chrome plating and a fine internal finish. These materials resist wear in continuous running, so pipe dimensions stay stable over long production runs.
How do these double wall corrugators differ from your 500 mm ID machine?
This range covers 40–250 mm pipe, mainly cable conduit, telecom ducts and smaller drains, with 5–10 HP corrugator drives. The 500 mm ID machine is a heavier line for 180–500 mm sewer and stormwater pipe. Choose based on the sizes your market buys most.
Can you supply a PVC double wall corrugator machine?
Our standard DWC lines are designed around PE and HDPE. PVC is heat-sensitive, so it needs a stabilised compound and a screw, die head and temperature profile designed for it. Send your compound details and pipe sizes and we will confirm the right configuration.
When does a double wall corrugated LDPE pipe extrusion line make sense?
LDPE gives a softer, more flexible DWC pipe that bends around obstacles. It suits light-duty conduit and farm drainage where high ring stiffness is not required. For load-bearing underground pipe, HDPE or PP is still the better choice.
Where does Volcano build its machines as a DWC corrugated pipe machine manufacturer in India?
Every machine is designed and built at our works in Naroda GIDC, Ahmedabad, where we have made corrugators since 1997. Our team works with plastics institutes, laboratories and raw-material producers. We follow standardised design and manufacturing methods, so parts are consistent from one machine to the next.
What do you need from me to quote a double wall corrugated pipe machine price?
Please send:
- Pipe sizes (ID/OD) and the standard you need to meet
- Raw material, and whether the inner and outer walls differ
- Target output
- Single or two-colour pipe
- Destination country and power supply
With these we can propose the right model, extruder and mould sets.
Which markets can a new DWC pipe plant supply?
Demand comes from:
- Underground power and telecom cabling
- City drainage
- Highway and rail projects
- Solar parks
- Agriculture
DWC uses less polymer per metre than solid-wall pipe, so profit depends heavily on raw-material efficiency.
Can a double wall plastic corrugator plant make pressure water pipe?
No. DWC pipe is for non-pressure, gravity-flow uses: drainage, sewerage, culverts and cable protection. Pressurised water supply needs solid-wall pipe, which we offer from 16 to 100 mm (see our Plastic Extrusion Machine page).
Can size and brand marking be added to a DWC extrusion machine line?
Yes. Pipe for tenders usually needs continuous marking of size, class, standard and batch. A marking unit is fitted between the puller and cutter and linked to line speed. Mention it in your enquiry so it is planned into the layout.
