PVC, Poly & Drainage Pipes

PVC pressure pipe for irrigation, water supply and general water transfer. This range covers nominal sizes from 15mm to 300mm in Class 9, Class 12 and Class 18, with the available classes varying by size.

Manufactured from rigid, unplasticised PVC (PVC-U) to AS/NZS 1477. The smooth internal surface helps limit friction losses. Choose the pipe size to suit the required flow, pipe run and available pressure.

Nominal size is the name used to identify the pipe and matching fittings; it does not state the exact inside or outside diameter. For example, a nominal 50mm pressure pipe has an approximate outside diameter of 60.4mm. For a given nominal size, the outside diameter remains the same across pressure classes, while a thicker wall reduces the internal diameter.

Class 9, Class 12 and Class 18 are also called PN9, PN12 and PN18. Their nominal working pressure ratings at 20°C are 900kPa, 1200kPa and 1800kPa respectively. Allowable working pressure reduces above 20°C. Select the class to suit the system’s working pressure and pressure surges, and use fittings with a suitable pressure rating.

The 155mm pipe is a specialised borecasing size used to line water bores. Its approximate outside diameter is 168.2mm, so it requires fittings matched to that diameter. Standard 150mm pressure fittings do not fit.

Select the jointing method and fittings to suit the pipe supplied. Solvent weld joints use priming fluid and pressure-rated solvent cement; Type P is used for standard interference-fit pressure joints. Rubber ring joints use the specified sealing ring and lubricant. Follow the manufacturer’s jointing instructions, including curing times for solvent weld joints, before pressurising.

For buried installations, provide suitable bedding and backfill to support the pipe and protect it from sharp stones. Above ground, use suitable supports and allow for expansion and contraction as the pipe temperature changes. Follow the manufacturer’s installation guide for the site conditions.

PVC Pressure Pipe Dimensions

PVC stormwater pipe for rainwater and surface-water drainage. Choose the nominal size to suit the drainage system and required flow.

The range covers 75mm to 300mm, including 150mm foam-core pipe. Stormwater pipe carries rainwater and surface runoff in non-pressure drainage systems. It is not suitable for pumped pressure or sewerage applications.

Nominal size identifies the pipe size and matching fittings. It is not the exact internal or outside diameter. For example, 150mm stormwater pipe has an outside diameter of approximately 160mm. Stormwater and pressure pipe of the same nominal size can have different outside diameters.

SN describes pipe stiffness, or resistance to deformation under external loads. A higher SN indicates greater stiffness. It is not a pressure rating.

150mm, 225mm and 300mm stormwater pipe shares the outside diameters of the corresponding DWV sizes, allowing matching stormwater or DWV socket fittings to be used for stormwater drainage. Match the socket size and joint type to the pipe; fittings that insert inside the pipe need a separate internal-diameter check.

Use fittings matched to the pipe size and outside diameter. For solvent-weld joints, cut square, remove burrs, clean and prime the joint surfaces, then apply Type N solvent cement and assemble as directed in the jointing guide. Allow joints to cure before use.

Above-ground pipework needs suitable support. Below-ground pipework needs prepared bedding, side support and backfill, with cover appropriate to traffic and other loads. Follow the installation guide and the requirements for the installation.

PVC DWV pipe for drain, waste and vent systems. Choose the nominal size and stiffness class to suit the installation.

The range covers 40mm to 300mm, including 100mm SN6 foam-core and solid-wall pipe, with stiffness classes varying by size. Select the size and stiffness class to suit the installation. SN describes pipe stiffness, or resistance to deformation under external loads. A higher SN indicates greater stiffness. It is not a pressure rating. Standard sizes below 100mm are specified by wall thickness.

Nominal size identifies the pipe size and matching fittings. It is not the exact internal or outside diameter. For example, 100mm DWV pipe has an outside diameter of approximately 110mm. DWV and pressure pipe of the same nominal size can have different outside diameters.

Use DWV fittings matched to the pipe size. For solvent-weld joints, cut the pipe square, remove burrs, clean and prime the joint surfaces, then apply Type N solvent cement and assemble as directed in the jointing guide. Allow the joint to cure before testing or use.

Above-ground pipework needs suitable support. Below-ground installations need prepared bedding, side support and backfill suited to the site and loading conditions. Follow the installation guide and the requirements for the installation.

PE100 compressed-air pipe rated PN25 and supplied in 6m straight lengths. Designed for fixed compressed-air distribution systems in workshops, factories, compressor rooms and industrial facilities.

For compressed-air service, the permissible operating pressure is 1600 kPa at 20°C. PN25 identifies the pipe’s nominal pressure class, while the lower compressed-air operating pressure allows for the additional safety factor required when conveying compressed gas. The allowable operating pressure reduces as temperature increases.

PE100 is a high-strength polyethylene grade used for pressure pipe. It is lightweight, corrosion resistant and does not suffer from internal rust or scale build-up. Its smooth internal bore supports efficient airflow and helps reduce unnecessary pressure loss through the system.

The blue base colour assists with compressed-air service identification in accordance with AS 1345. The pipe is manufactured in Australia to AS/NZS 4130 and AS/NZS 4131.

Pipe diameter must be selected according to the required airflow, total pipe-run length and distance from the compressor to the furthest outlet. Use only compatible PE fittings and joining methods specifically approved for compressed-air service.

Prices given on this page are for supply within Western Australia. Please contact us if you require longer coils of this pipe, or if you would like availability and pricing outside WA.

Corrugated HDPE stormwater pipe with an SN8 stiffness class, supplied in nominal 6 metre straight lengths. It is designed for underground gravity stormwater drainage and water-conveyance systems used in civil, subdivision, commercial, industrial and infrastructure projects.

Manufactured from PE100 high-density polyethylene, the pipe has a corrugated external profile for underground strength and a smooth internal bore for efficient drainage flow. SN8 is the pipe’s stiffness class for underground installations, and the pipe is suited to non-pressure applications.

Corrugated HDPE pipe is identified by its nominal diameter. The nominal size may differ from the actual internal diameter, outside diameter and socket dimensions, which can vary between pipe sizes and manufacturers.

Pipe lengths are joined together using O-rings and lubricant, which are available with the pipe at no extra cost upon request. Each length of pipe has a socket for joining to another length of pipe.

Installation requirements should be confirmed for the project conditions, particularly beneath roads, construction equipment, railways or other heavily loaded areas. Installed performance depends on suitable trench preparation, bedding, backfill material, compaction, cover depth and expected external loading.

Type B copper pipe for hot and cold water plumbing, supplied in 6m straight lengths. Available in DN15, DN20 and DN25 nominal sizes.

Nominal copper sizes are trade designations. They do not describe the actual outside diameter, so use the dimension table when matching tube and fittings.

Working pressure depends on the tube size, temper, operating temperature and jointing system. Use copper-tube fittings and jointing methods suitable for the intended service.
