Corrugated Spiral Pipe Production Line

BENTHOMAS Metal Spiral Corrugated Pipe Production Line – The Ultimate in Flexibility and Strength

Introduction
The BENTHOMAS Metal Spiral Corrugated Pipe Production Line represents a pinnacle of continuous roll-forming technology.Engineered for high-volume manufacturing, this automated system specializes in producing endless-length helical pipes with a characteristic corrugated profile. These pipes are renowned for their superior strength-to-weight ratio, flexibility, and durability, making them indispensable across a wide range of applications including stormwater and sanitary drainage, culverts, ventilation ducts, cable conduits, and structural pilings. Our line delivers unmatched production efficiency, consistent quality, and the ability to quickly adapt to varying pipe diameters and specifications.

Core Machine Configuration & Technical Process

The production process is a seamless, continuous operation that transforms flat metal coils into finished spiral pipe:

1. Coil Loading & Feeding System:
· A heavy-duty decoiler accommodates large coils of raw material (galvanized steel, aluminized steel, stainless steel, or aluminum).
· A precision servo-feeding mechanism ensures smooth, controlled, and consistent material flow into the forming section.
2. Corrugation Forming Unit:
· The heart of the initial stage where the flat strip passes through a series of precision-engineered rolling dies.
· These dies progressively form the desired corrugation profile (e.g., annular or helical ribs) onto the metal strip, significantly enhancing its circumferential stiffness and moment of inertia.
3. Spiral Winding & Lock-Seaming Mill:
· This is the defining component of the line. The corrugated strip is fed at a controlled angle onto a rotating mandrel (cage or drum).
· Through a precision helical winding process, the strip is coiled upon itself. A critical in-line lock-seaming mechanism (often a continuous interlock or hook-and-lip seam) securely joins the adjacent edges of the winding strip, creating a continuous, leak-resistant, and structurally sound pipe.
4. Diameter Control & Cutting System:
· The pipe diameter is precisely determined by the feed angle of the strip and the speed of the winding mandrel, allowing for quick changeovers between different sizes without changing tooling.
· A synchronized traveling cut-off saw or plasma cutter cleanly severs the continuously produced pipe to pre-set lengths without stopping production.
5. PLC Automation & Control Panel:
· The entire line is governed by an advanced Programmable Logic Controller (PLC).
· The intuitive Human-Machine Interface (HMI) allows operators to easily input parameters such as pipe diameter, wall thickness (via strip width), corrugation pitch, and cut length. The system ensures synchronization of all motors and provides real-time diagnostics.

Key Technical Advantages

· Continuous Infinite Length Production: Capable of producing pipes longer than traditional methods, reducing field joints and installation time.
· Rapid Diameter Changeover: Adjusting pipe diameter is quick and mechanical, often without replacing expensive molds, offering tremendous production flexibility.
· Exceptional Structural Integrity: The combination of corrugated profile and helical lock-seam creates a pipe with high ring stiffness, excellent flexibility to withstand ground settlement, and superior load-bearing capacity.
· Material & Profile Versatility: Can process a variety of metallic materials and can be tailored to produce different corrugation shapes (e.g., U-shaped, V-shaped) to meet specific hydraulic or structural requirements.
· High Automation & Efficiency: Minimal manual intervention leads to consistent quality, high output rates, and reduced labor costs.
· Optimized Material Usage: The continuous process minimizes scrap and waste compared to segmental manufacturing methods.

Primary Applications

· Drainage & Culverts: Large-diameter pipes for highway, railway, and land development stormwater management.
· Sanitary Sewers & Ventilation: Corrosion-resistant pipes for wastewater systems and industrial air handling.
· Cable Protection Conduits: For protecting power and telecommunication cables in underground installations.
· Micro-Tunneling & Piling: Used as jacking pipes for trenchless technology or as lightweight yet strong structural piles.
· Agricultural and Industrial Drainage.
