PVC as per Australian/NZ Standards - Storm Water Pipe

INTRODUCTION

Zenith offers a complete range of STORMWATER pipes that comply with AS/NZS1254. STORMWATER pipe systems offer major advantages over traditional piping systems which causes corrosion, installation economics, operating inefficiencies, and significant maintenance costs.

UPVC is the predominant material used in STORMWATER pipes. The economic advantages are well accepted, they are lightweight, resistant to a wide variety of chemicals, do not support combustion, they are impervious to bacterial and fungal attack and are not subject to electrolytic corrosion. The Pipes are designed with a high impact strength, which helps prevent damage during handling and installation. All parts assemble easily using either solvent cement or rubber seal rings to accommodate thermal or ground movement.
