Access WEBON's complete library of PVC-O pipe technical documentation. From detailed white papers comparing PVC-O with PVC-U and PE pipe materials, to international ISO 16422 standards and Chinese national standards (GB/T 41422-2022, CJ/T 445-2014) — all resources are freely available for engineers, project teams, and procurement decision-makers.
PVC-O Pipe White Paper
Original engineering documentation covering wall thickness specifications, design methodology, and comparative technical indicators between PVC-O, PVC-U, and PE100 pipe materials.
- PVC-O Pipe Wall Thickness Table Sheets
- PVC-O Pipe Design White Paper (CN) Doc
- PVC-O vs PVC-U and PE: Key Technical Indicators (Chinese Version) Sheets
- PVC-O vs PVC-U and PE: Key Technical Indicators Sheets
Chinese Technical Standards for PVC-O Pipes
China maintains two parallel standards for PVC-O pipes: the industry standard CJ/T 445-2014 (issued by the Ministry of Housing and Urban-Rural Development) and the national standard GB/T 41422-2022 (issued by the State Administration for Market Regulation). Both standards align with the ISO 16422 framework while incorporating domestic application requirements.
How to Use These Documents
These technical resources serve different stages of the project lifecycle:
- Project planning & design — Use the wall thickness table and design white paper to specify pipe dimensions and pressure ratings for your hydraulic design.
- Material selection — The PVC-O vs PVC-U vs PE comparison sheets provide the technical indicators needed to justify material selection to project owners.
- Compliance & certification — Chinese standards GB/T 41422 and CJ/T 445 are required for projects in mainland China; for international projects, refer to the ISO 16422 standard series.
- Quality acceptance — Use the relevant standards as the basis for incoming inspection and acceptance testing of delivered PVC-O pipes.
All documents open in a new tab and are hosted on Google Drive for direct access. If you require the documents in a different format or need engineering consultation on applying these standards to your project, please contact our technical team.
