Corrugated Steel Culvert Pipe Drainage Pipe Roll Forming Machine ZTRFM spiral corrugated pipe roll forming machine

Zhongtuo Corrugated Steel Pipe Roll Forming Machine Spiral Culvert Pipe Production Line

This heavy-duty Zhongtuo (ZTRFM) corrugated steel pipe roll forming production line is specifically designed for the continuous manufacturing of spiral corrugated steel culvert pipes, highway drainage pipes, underground passage culverts, and municipal stormwater conduits. Capable of processing 2.0 mm to 3.0 mm heavy-gauge galvanized steel strip (GI) with up to 1220 mm feeding width, this high-rigidity forming line integrates a 33 kW heavy electric motor drive, high-precision corrugation roller stands, automatic servo hole punching station, synchronized curving and seaming units, and dual 380V/440V operating voltage, producing structural corrugated culvert pipes with diameters from 1000 mm to 6000 mm (1.0 m to 6.0 m) and pipe lengths from 1 m to 12 m at adjustable speeds up to 35 m/min.

• Large Diameter Culvert Forming: Produces heavy-duty corrugated culvert pipes with inside diameters spanning from 1000 mm up to 6000 mm (1.0 m to 6.0 m) and custom lengths from 1 m to 12 m.
• Heavy-Gauge 2.0–3.0 mm Steel Forming: Robust welded frame and solid forged steel roller passes withstand high forming pressures required for 2.0 to 3.0 mm thick hot-dip galvanized steel strip.
• Integrated Servo Hole Punching Unit: Synchronized online servo punching station punches pre-aligned connecting bolt holes on corrugated sheet edges for fast on-site bolted pipe assembly.
• Standard Corrugation Pitch Options: Supports standard structural corrugation profiles including 230 mm spiral pitch and standard engineering pitches (1.5", 2.67", 3", 5", 6" / 38 mm to 152.4 mm).
• High Speed 1–35 m/min Production: Powerful 33 kW motor and high-torque gear transmission deliver flexible, adjustable forming speeds from 1 m/min up to 35 m/min.
• Heavy Hydraulic Decoiler Integration: Heavy-duty motorized uncoiler with hydraulic expansion and overhead snubber arm safely controls heavy galvanized steel coil payout.

Technical Specifications

Heavy-Duty Forming Line & Servo Punching Unit

The heavy-gauge corrugation line is constructed with massive steel plate arch frames, precision ground forming roller passes, and an integrated servo punching unit to pre-punch perimeter bolt holes with high accuracy.

Hydraulic Decoiler & Field Civil Engineering Applications

Equipped with a hydraulic expanding uncoiler and motorized coil snubber arm, the line smoothly unwinds heavy galvanized steel coils. The finished corrugated pipes provide exceptional strength for underground highway culverts, municipal drainage, and bridge underpasses.
