SJ60, SJ75, SJ90, SJ120, SJ150 single screw extruders with special screw design, suitable for PE, PP and other materials. Using buffering mixing section and large L/D ratio 36:1 screws for good plasticization, high output and wide adaptability to raw materials. Bimetallic screw and barrel effectively improve wear resistance and corrosion resistance, achieving longer service life.

Material is extruded from the extruder through the inner and outer dies of the double layer pipe die head. Suba die head short channel design (reduced by 25%) effectively lowers melt pressure, achieving low temperature, low pressure extrusion — production efficiency 25% higher than conventional die heads. Dynamic inner and outer wall thickness adjustment without stopping extruders. Suitable for HDPE and PP materials. Die head fixed on bracket for simple, quick size changes.

The corrugator adopts a closed loop pressure water cooling system for high forming efficiency. Patented design — mould replacement requires no water tube disassembly. All mould sizes share the same center height; no platform adjustment needed when changing moulds. Left and right frames open and close electrically for easy maintenance. Equipped with UPS and remote control system.
View LineEvery unit of the production line is engineered for precision, durability, and maximum output.
Optimized hydraulic design increases output by 25%, achieving low-temperature and low-pressure extrusion. Edge Flow design keeps inner layer wall thickness and deviation adjustment stable and precise.
Buffering mixing section and large L/D ratio 36:1 screws for good plasticization, high output, and wide adaptability to raw materials. Bimetallic screw and barrel for improved wear resistance.
Patented closed loop pressure water cooling. No platform design — all mould sizes share the same center height, no corrugator adjustment when changing moulds. Schneider PCC control system.
High-quality aluminium alloy moulds. Optimized cooling chamber with maximum cooling cross-section area. Water temperature control system ensures excellent pipe quality.
Chipless cutter — precise, noiseless and dust-free cutting. Innovative trigger mechanism with turntable bearings, linear guide rails, and dual Italian hydraulic systems.
Automatic pipe turn-over and stacking reduces labor requirements. Adjustable counting and stacking configuration adapts to different pipe diameters and lengths.
Corrugated pipes produced by Suba machinery serve critical industries worldwide.
PP, PE, and PVC corrugated conduit runs behind every wall and under every floor — protecting electrical cables, carrying potable water, and routing heating circuits. Suba production lines supply the pipe manufacturers equipping modern residential and commercial construction.
PP, PE, and PVC double-wall corrugated pipes produced on Suba lines handle the loads cities put underground: storm-water drainage from OD200mm to OD2000mm, sewer trunks, and buried cable conduit for power grids and fibre networks. Built to survive decades of soil pressure and chemical exposure.
PE and PP corrugated tubing — manufactured on Suba small-diameter lines — delivers the flexibility and bio-compatibility required in ventilators, anesthesia circuits, and respiratory therapy devices where dimensional accuracy is non-negotiable.
PP and PE corrugated conduit protects wiring harnesses, fuel lines, and brake circuits in every vehicle from heat, vibration, and abrasion. Suba small-diameter lines produce tight-tolerance profiles at the throughput automotive supply chains require.
PP and PE flexible corrugated profiles — produced on Suba lines — serve as water inlet and drain hoses inside every washing machine, dishwasher, and air-conditioning unit, passing pressure cycles and chemical resistance tests before any appliance reaches certification.
PP, PE, PVC, and recycled materials — when the application falls outside standard categories, Suba's configurable corrugator tooling produces round, oval, single- or double-wall profiles for pool filtration loops, HVAC duct liners, district heating sleeves, and industrial process conduit.
