Suba machinery corrugated pipe extrusion line includes automatic feeding system and hopper with drying function. The developed SJ65, SJ75, SJ90, SJ120, SJ150 extruders use a buffering mixing section and large L/D ratio screws, which has a good plasticization, high output and wide adaptability to raw materials; the feeding section with a spiral buffer design, direct water cooling and automatic temperature control system, which can increase the conveying efficiency at the feeding end. Bimetallic screw and barrel effectively improve the wear resistance and corrosion resistance, service life is increased by 2-3 times; Extruder is equipped with a fine-tuning base to make sure a better connection with the die head; Gearbox adopts vertical structure which achieves compact structure, low noise index, strong carrying capacity and high transmission efficiency; The optimized co-extrusion system of multiple extruders achieves optimal matching production of various specifications. The production of small sized products does not cause waste of the extrusion system, and the production of large sized products has sufficient output.

The blank is extruded from the extruder through the inner and outer die of the double layer pipe die head. Double layer pipe die head is suitable for HDPE and PP materials. Die head is fixed on the die head bracket, and die head replacement is simple and quick. Suba die head short channel design (shorten about 25%), effectively lower down the melt pressure, achieves low temperature low pressure extrusion, production efficiency increases 25%; The low extrusion melt pressure reduces requirement of parts, the material leakage risk at the connection is greatly reduced. The double channel starts from the die head body and reaches the die exit, it achieves multi extruders extrude two layers. The optimized design of double layer pipe die head, the inner and outer wall thickness adjustment is very stable and convenient, which achieves dynamic adjustment, no need to stop extruders, no need to loosen any fastening screws, shorten adjustment time and reduce the material leakage risk.
Corrugated pipes produced by Suba Machinery serve critical industries worldwide.
Single-wall corrugated PE and PP conduit produced on SL180 and SL180P protects electrical wiring in buildings, residential developments, and industrial installations. Lightweight and flexible, it routes around obstacles where rigid conduit cannot go.
Flexible corrugated profiles produced on SL180, SL180P, 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 drainage pipes handle the runoff loads that roads, agricultural fields, and urban developments generate — from small-diameter land drainage to large-bore stormwater collectors. SL180P, SL300, and SL600 lines cover the full diameter range.
PP and PE double-wall corrugated sewer pipes carry domestic and industrial wastewater from collector branches to trunk mains. SL180P, SL300, and SL600 meet 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 OD40mm to ID1600mm corrugated pipe production for different applications.
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.

Two 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 a smooth inside layer, double-wall corrugated pipes ensure good water flow.
