“

We switched our municipal water supply project from PVC-U to Webon's PVC-O pipes three years ago. The DN315-PN16 pipes weigh 30% less, which cut our installation labor costs significantly. Not a single failure across 40 km of installed pipe.

Trinh Van Minh

Project Director

“

For our 5,000-hectare irrigation network, the Class 500 pipes from Webon handled pressures up to PN25 without issue. The impact resistance is remarkable — our crews have dropped pipes during transport with zero cracks. ISO 16422 compliance made approvals straightforward.

David Okonkwo

Chief Engineer

“

The full range of PVC-O fittings — couplings, tees, elbows and the steel-plastic options for PN25 — means we source everything from one supplier. The sealing rings have held up perfectly under continuous industrial fluid conveyance for two years now.
