PMV复合实壁开挖管

DN100-800mm | 环刚度SN8-SN16

PMV Composite Solid Wall Pipe (Open-Cut) is specifically designed for traditional open-cut installation methods in power and communication cable protection applications. ## Composite Structure The PMV composite construction combines the best properties of multiple materials: - **Inner Layer**: Smooth surface for low friction cable pulling - **Core Layer**: High-strength reinforcement for ring stiffness - **Outer Layer**: UV-stabilized protective layer ## Ring Stiffness Options Multiple ring stiffness grades available to match burial depth and load requirements: - **SN8**: Standard installations, shallow burial - **SN10**: Medium depth, light traffic areas - **SN12.5**: Deep burial, road crossings - **SN16**: Heavy traffic, industrial applications ## Open-Cut Advantages Designed specifically for open-trench installation: - Rigid construction for easy alignment - Socket joints with rubber ring sealing - Customizable lengths to minimize joints ## Quality Standards Manufactured to CJ/T 493 standard with comprehensive quality control including ring stiffness testing, impact resistance verification, and dimensional inspection.
