PVC-U profile pipes are custom-engineered with specialized cross-sections including square, rectangular, oval, trapezoidal and irregular shapes, manufactured via precision extrusion with custom tooling.

Retaining the inherent advantages of PVC-U—lightweight, high strength, corrosion resistance, weatherability and electrical insulation—the pipes fulfill non-standard requirements for special fluid conveyance, cable protection, structural support, equipment ducting and architectural components. High dimensional accuracy and customizable joints (socket, flange, snap-fit) ensure adaptability to unique installation environments.

Applications include industrial specialty piping, building custom drainage, equipment ventilation, agricultural specialty irrigation, rail transit trunking, environmental protection facilities and mechanical structural components.

Notes on pipelines：

1. Customized special-shaped cross-section pipes, must use matching special fittings for connection, prohibit random modification and forced assembly.

2. Handle and hoist gently according to the structural characteristics, avoid concentrated stress on special-shaped parts causing deformation and fracture.

3. Determine the installation method and fixing measures according to the customized use scenario (special fluid transportation, cable protection, structural support).

4. Avoid local heavy pressure and sharp impact during use, protect the special-shaped pipe wall from damage; comply with the design use scope, do not use over-load.

5. Store in a dry and ventilated place, avoid deformation caused by high temperature and long-term stacking; mark the specification and use direction clearly to avoid wrong installation.

6. Regularly check the structural integrity and joint sealing of special-shaped parts, and maintain and replace them in time according to usage conditions.
