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.
View DetailsCorrugated pipes produced by Suba machinery serve critical industries worldwide.
Single-wall corrugated PE and PP conduit produced on the SL180 protects electrical wiring in buildings, residential developments, and industrial installations. Lightweight and flexible, it routes around obstacles where rigid conduit cannot go.
PP and PE double-wall corrugated drainage pipes handle the runoff loads that roads, agricultural fields, and urban developments generate — from small-diameter land drainage to large-bore stormwater collectors. SL180, SL300, and SL600 lines cover the full diameter range.
Flexible corrugated profiles produced on SL180 and SL300 lines route fresh air and exhaust through walls, floors, and ceilings in residential and commercial HVAC systems. Corrugated geometry combines flexibility with resistance to kinking under tight installation bends.
PP and PE double-wall corrugated sewer pipes carry domestic and industrial wastewater from collector branches to trunk mains. The full diameter range across SL180, SL300, and SL600 meets every network tier — from building connections to municipal collector sewers.

Need help choosing the right production line?
Get Expert ConsultationCorrugated pipe has many advantages compared with similar pipes due to its material HDPE/PP and special pipe profile.
Pipe is with less weight and machine is with closed loop water cooling system, thus achieves high production speed.
Due to the structure of corrugated pipe, it has a higher ring stiffness than smooth pipes at the same weight.
From ID 32 mm to OD 2000 mm corrugated pipe production for different application.
Double wall corrugated pipe saves material compared to HDPE pipes at same diameter and same ring stiffness.
Double layer corrugated pipe has a deflection of up to 30%.
Our engineers can help you select the right production line for your application requirements.

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.
View DetailsTwo corrugated pipes can be easily joined by rubber ring.
PE or PP both applicable; Virgin and recycled high density polyethylene can be both used depending on different usage.
With less weight, corrugated pipes are much easier for handling, and no need heavy equipment to install which achieves an easy installation.
Double wall corrugated pipes are widely used for drainage, sewage, cable protection, water collection and etc.
With smooth inside layer, double wall corrugated pipes ensures a good water flow.
