PVC Pipes

Product Overview

DN 110–400mm, PN10/12.5/16, gray/white color. Rubber ring socket joint with EPDM seal. Conforms to GB/T 10002.1. Ideal for municipal water supply and buried large-diameter pipelines.

With a pre-installed EPDM sealing ring in every bell socket, this PVC rubber ring pipe pushes together in seconds without solvent cement or threading, absorbing ground settlement and thermal contraction across DN110-400 buried mains while retaining the full PN10/12.5/16 pressure rating of solid-wall UPVC.

Key Features

Push-Fit Rubber Ring Joint: Pre-lubricated EPDM bell on every PVC rubber ring pipe slides onto the spigot by hand, cutting jointing time by roughly 50% compared with solvent cement.
Ground Settlement Resistant: The EPDM-ring bell on this rubber ring PVC pipe flexes slightly, absorbing differential settlement and thermal contraction without opening a leak path.
Large-Diameter Buried Mains: DN110-400 sizes of PVC rubber ring pipe cover municipal water transmission where solvent cement would be slow and impractical on long buried runs.
Full Pressure Rating Retained: The rubber ring PVC pipe joint holds PN10/PN12.5/PN16 working pressure, the same as solvent-cement joints of equivalent size.
EPDM Long-Life Seal: The EPDM sealing ring inside every PVC rubber ring pipe resists aging, ozone and water-treatment chemicals for a 50-year service life.
Retestable & Repairable: Each PVC rubber ring pipe joint can be disassembled for repositioning and resealed with a replacement ring, a flexibility solvent joints do not offer.

Production

Manufacturing Process

Every PVC rubber ring pipe is extruded on twin-screw lines and the bell socket is thermoformed in-line; the spigot end is chamfered and marked with the insertion depth line so crews push home to the correct position every time.

Quality Control & Testing

Assembled PVC rubber ring pipe joints undergo internal-pressure leak testing per ISO 1167, EPDM rings are checked for hardness and compression set per ISO 4671, and 100% of bell sockets are gauged for diameter and groove depth before the rubber ring is fitted.

Raw Material

The pipe wall is extruded from lead-free virgin UPVC and the seal from long-life EPDM rubber, making every rubber ring PVC pipe a fully non-toxic, non-rusting, 50-year-design-life product for potable water mains.

Applications

Municipal buried water supply mains and distribution lines - long 6m PN10 PVC rubber ring pipe runs under roads where the push-fit joint absorbs minor settlement without leaking.
Large-diameter rural and irrigation transmission lines - DN250-400 rubber ring PVC pipe laid fast across fields without solvent cement setup time or weather delay.
Industrial process water and cooling-water buried supply - EPDM-sealed PVC rubber ring pipe joints that handle thermal cycling and plant ground movement while staying pressure-tight.
Trench repair, pipe relocation and emergency bypass lines - reusable PVC rubber ring pipe lengths that can be un-jointed and re-laid without cutting, ideal for temporary or adjustable installations.
