HDPE Spiral Corrugated Pipe Production Line for Sewer Renovation with PLC Control

This large diameter HDPE spiral corrugated pipe machine is a complete corrugated pipe extrusion machine and corrugated pipe making machine for producing Weholite-type hollow-wall corrugated pipes from Ø400mm up to Ø3000mm. Using multi-material HDPE, PP and PVC processing, it forms an I-Beam structured wall with a high strength-to-weight ratio and ring stiffness of SN4, SN8 or SN16. As a corrugated pipe machinery line built for large-diameter sewage, stormwater and culvert drainage, it helps pipe manufacturers enter and grow in the structured wall pipe market.

The finished large diameter corrugated pipes replace concrete and cast iron in sewage collection, stormwater drainage and road culvert projects. They offer up to 50 years of service life, strong chemical resistance and a choice of rubber ring socket or electro-fusion joints. A PLC keeps this automatic corrugated pipe line stable from profile extrusion to final cutting, so you get consistent corrugated plastic pipe production shift after shift.

Compared with traditional concrete and clay drainage pipe, pipes from this HDPE corrugated pipe extruder are lighter, faster to lay, easier to transport and far less likely to crack or corrode underground. That lowers installation, maintenance and lifetime cost for municipal and industrial buyers, which is why this spiral corrugated pipe machine is widely chosen by manufacturers in the Middle East, Russia, Central Asia and Africa.

• Ø400–3000mm Large Diameter Coverage: Four spiral corrugated pipe machine models, SKRG-1200 to SKRG-3000, cover small sewage collectors up to the largest culverts. One supplier can serve your whole drainage pipe product range.
• I-Beam Structured Wall: Hollow-wall corrugated drainage pipes carry heavy ground loads while staying light for trench handling, lowering installation cost and speeding up laying.
• HDPE, PP and PVC in One Line: One corrugated pipe machinery line switches between materials, so manufacturers can answer different tenders without extra equipment. This makes the PVC corrugated pipe line option available alongside HDPE and PP production.
• Chemical Resistance and Long Life: Corrugated plastic pipe production on this line delivers pipes that resist acids, alkalis and salts, for up to 50 years of buried service in aggressive soil and industrial wastewater.
• PLC Synchronized Control: Precise coordination of extrusion and winding gives uniform wall thickness and consistent quality on every corrugated pipe, with stable operation during continuous mass production.
• Flexible Jointing: Rubber ring socket and electro-fusion joints suit new trenches and the retrofitting of existing networks, including trenchless installation.
• High Output, Low Waste: Output from 320 to 800 kg/h across the SKRG series gives steady capacity for municipal tenders and export orders.
• Customization Available: Pipe diameter, ring stiffness and machine configuration can be matched to your market standards, samples and project specifications.

The two processes keep ring stiffness, wall geometry and bonding strength consistent across the finished corrugated pipes. The extruded I-Beam profile is wound around the forming mandrel under precisely controlled tension and fused with melt adhesive into a complete hollow-wall pipe. This is how the corrugated pipe extrusion machine makes large-diameter pipe without a large-diameter mould.

This full-set HDPE PP PVC spiral corrugated pipe production line, also known as a double wall corrugated pipe production line in many markets, is a complete plastic pipe extrusion line built from two core synchronized processing units and an integrated PLC control system. It is widely supplied to pipe manufacturers and municipal infrastructure projects across the Middle East, Russia, Central Asia and Africa.

Includes a high-torque single screw extruder (SJ-65 / 80 / 90, model-configured), square-tube I-Beam die head, stainless-steel vacuum calibration table, spray cooling tank and heavy-duty haul-off machine. This HDPE pipe extruder line section outputs dimension-stable I-Beam structured profiles for making HDPE, PP and PVC Weholite-style corrugated drainage pipes, with the vacuum calibration table holding profile shape before winding.

Composed of a secondary melt-adhesive extruder, a Weholite-spec spiral winding machine (winding speed 0.3–12 m/h) and an automatic precision cutting system. This corrugated pipe making machine unit shapes complete hollow-wall pipes under precisely adjusted winding tension for municipal sewage and stormwater drainage pipe production.

Full-set centralized control synchronizes profile extrusion and spiral winding. It keeps ring stiffness stable, wall thickness even and finished-pipe quality reliable during long-term continuous mass production on this corrugated pipe production line, including large-diameter structured-wall drainage pipes.

Pipes from this corrugated drainage pipe machine serve municipal and industrial drainage infrastructure across the Middle East, Russia, Central Asia and Africa:

• Municipal Sewage Drainage: Sewage collection networks and main sewer trunk lines using large diameter corrugated pipe. SN8 / SN16 ring stiffness suits city-wide sewage renovation and new-build sewer systems.
• Stormwater Management: Stormwater culverts, flood-control channels and rainwater retention systems, from small branch collectors to heavy-duty trunk culverts.
• Road Culverts and Highway Drainage: Highway crossings, road culverts and underground utility conduits needing high ground load capacity under heavy traffic.
• Industrial Wastewater: Chemical-resistant discharge pipelines for plants and industrial parks, where acids, alkalis and salts attack concrete and metal pipe.
• Pipeline Retrofitting: Replacement of aged concrete, clay and cast-iron drainage networks, with rubber ring socket joints that fit existing layouts and support trenchless installation.
