ULTRAPIPE: MULTI-LAYER SEWER AND DRAIN SYSTEMS
Ultrapipe has smooth inner and outer walls separated by a dense cellular foam core. The cellular foam core is constructed from 100% recycled PVC-U material, secured from DPI PLASTICS own PVC waste. The multi-layer construction is engineered to deliver all the expected attributes of a world class sewer pipe.
- A smooth inner wall for optimal flow and lower cost;
- A smooth outer wall which makes the product compatible with all SANS jointing systems;
- Low pipe mass that contributes to competitive pricing and economic use;
- Ultrapipe carries the SANS 1601 mark of approval.
- Use of recycled material is kinder to the environment.
DPI PLASTICS...THE MARKET LEADER
DPI Plastics is committed to professional standards, quality products and service. Our extensive product range is manufactured to local and internationally accepted standards in ISO 9001 factories.
We continuously strive to introduce new technologies and products with emphasis on cost effectiveness, ease of installation and aesthetics.
Millions of installed metres are testimony to our dedicated interaction with the trade.
PVC -U: THE MATERIAL OF CHOICE
- PVC-U (unplasticised polyvinyl chloride) is selected as a pipe material internationally because of its excellent performance characteristics.
- Resistance to abrasion, scouring, acid and alkaline attack.
- Good impact qualities, important during installation and transportation.
- Not damaged by modern cleaning methods.
- Ability to be modified.
- Recyclability - PVC can be recycled and is reused in the centre layer of Ultrapipe, saving our scarce resources
PIPE WALL CONFIGURATION
The multi-layered structured wall configuration comprises of three layers, which provides strength and resistance to soil loads.
The recycled material in the foamed centre layer is generally not in contact with the soil or effluent.

The introduction of structured wall pipes to the South African market led to the preparation of the SANS 1601 specification. This introduced the concept of the pipe stiffness rating as a pipe classification. The use of kPa rating (100, 200 and 400 kPa) is often confused with the pressure class rating, but in fact relates to the amount of pressure to deform the pipe by 5% of its diameter.
The solid wall specification (SANS 791) has two pipe stiffness classes being class 51 (normal duty) and class 34 (heavy duty). These relate to 100 kPa and 300 kPa respectively.

PRODUCT RANGE - FITTINGS
Both the Durodrain ribbed and solid wall fittings range are compatible with Ultrapipe. Durodrain ribbed SANS 601: 110mm, Durodrain solid wall SANS 791: 110 and 160mm
A range of fittings has been developed for use with Ultrapipe. They incorporate our Rieber or Duroseal integral joint.

CODES OF PRACTICE
CUTTING AND JOINTING
It is important that the pipe ends and sockets are aligned and free of burrs, otherwise insertion into the seal ring will be difficult
Insert the pipe into the socket fully. For protection of the pipe ends use a lever against a wooden block.
Cut the pipe square with
a cross cut saw or angle
grinder depending on
the pipe size. Clean away
swarf. The pipe end must
CLEANING THE SEAL
It is important to ensure
that the seal is free of grit
and mud before making
the joint. Pipe ends are
often accidentally dipped
DPI Plastics supplies liquid
lubricant and a jelly-like
lubricant known as gel.
Both products are
designed for lubricating
Flexible rubber ring joints are available for all types of pipe and should be used in preference to rigid joints, allowing the pipeline to flex in the event of soil movements and also allowing for thermal change.

HANDLING, STORAGE AND TRANSPORTATION
Pipes and fittings should not be handled carelessly, as this may cause damage. Pipe should not be dropped or dragged along the ground.
Pipes should be stored on level, flat ground, free of stones. They may be stored on timber supports of at least 75mm width placed 1.5 metres apart with wide supports. The height of pipe stacks should not exceed 1.5 metres. All pipe stacks and stored fittings should be covered to avoid prolonged exposure to direct sunlight. Where the pipes are fitted with an integral socket, they should be stacked with sockets protruding at alternate ends.
A flat-bodied vehicle is ideal for transporting pipes. Pipes with integral cuffs should be loaded and spaced so that cuffs protrude at alternate ends. When a mixed load of pipes (i.e. varying diameters) is to be transported, the larger pipes should be placed at the bottom. Pipes should not overhang the vehicle by more than 1 metre.
