Corrugated pipe extruder UL

A corrugated pipe extruder that meets UL (Underwriters Laboratories) standards is a specialized machine used for manufacturing corrugated pipes from materials like HDPE, PVC, or PP, ensuring compliance with UL safety and quality requirements. These pipes are commonly used in electrical conduit, drainage systems, and industrial applications.

Key Considerations for Choosing a UL-Certified Corrugated Pipe Extruder

1. UL Compliance & Certification

Ensure the machine meets UL 651 (for PVC conduit) or UL 94 (for fire resistance), depending on the application.

The extruder should support production of flame-retardant and UV-resistant pipes if required by industry standards.

2. Material Compatibility

PVC (for electrical conduit)

HDPE/PP (for drainage, telecom, and cable protection)

Flame-retardant compounds if UL94-V0 compliance is required

3. Production Efficiency

Single-wall vs. double-wall pipe: Choose based on strength requirements.

High-speed corrugators: Ensure the extruder has an automated corrugation mold system for consistent wall thickness.

Vacuum or pressure forming: Helps with precision shaping of the corrugation.

4. Extruder Specifications

Screw Design: Single or twin-screw extruders based on material and production needs.

Extrusion Output: High-output models (e.g., 150-500 kg/hr) for large-scale manufacturing.

Cooling System: Air or water cooling to ensure proper pipe formation.

5. Die Head & Mold Design

Interchangeable mold systems for different pipe sizes (e.g., 16mm–500mm)

Quick-change mold design for efficiency in production shifts.

6. Automation & Control System

PLC control with HMI (Human-Machine Interface) for easy operation.

Automatic pipe cutting & stacking for high efficiency.

Laser measurement for pipe accuracy.
