1" PPR Pipe — Hot & Cold Water Supply Pipe, 32mm (Per Metre)

The Backbone of Every Modern PPR Plumbing System

The 1" PPR Pipe (32mm outer diameter) is a premium-grade Polypropylene Random Copolymer pipe engineered for reliable hot and cold water distribution in residential, commercial, and industrial plumbing systems. Larger than the standard 20mm and 25mm sizes, the 1" PPR pipe is ideal for main supply lines, riser pipes, and high-demand water distribution runs where greater flow capacity is needed. Its smooth green exterior and clean inner bore make it easy to work with, and its heat-fusion joints create permanent, monolithic connections that outlast the building itself.

Key Specifications

• Nominal Size: 1 inch — 32mm outer diameter
• Material: Polypropylene Random Copolymer (PPR) — food-grade, non-toxic
• Colour: Green — standard PPR pipe colour
• Temperature Rating: Suitable for hot water (up to 95°C) and cold water systems
• Pressure Ratings Available: PN10, PN16, PN20, PN25 — wall thickness varies by rating
• Connection Method: Heat-fusion (butt welding) — permanent, leak-free joints
• Inner Surface: Smooth bore — minimises friction loss and prevents scale build-up

Pressure Class Guide

• PN10 — Low pressure cold water systems
• PN16 — Medium pressure cold and warm water
• PN20 — Standard hot and cold water supply (most common)
• PN25 — High pressure and high temperature hot water systems

How It Connects

PPR pipes are joined using a heat-fusion welding tool that simultaneously melts the pipe end and the fitting socket. When pressed together, they fuse into a single, monolithic joint — stronger than the pipe itself and completely leak-proof. No glue, no clamps, no thread tape required.

Common Applications

• Main water supply and riser pipes in buildings
• Hot and cold water distribution in residential and commercial properties
• Solar water heater and boiler feed lines
• Overhead tank supply and distribution runs
• Industrial liquid transfer and process pipelines
• Compressed air systems (PN20/PN25 rated)

Why Choose PPR?

• ✅ Non-toxic and food-grade — safe for drinking water systems
• ✅ Corrosion and scale resistant — no rust, no deposits, no contamination
• ✅ Heat-fusion joints — permanent, zero-leak connections
• ✅ Long service life — 50+ years under normal operating conditions
• ✅ Lightweight and easy to install — no heavy tools or specialist skills required
