Ultracor PVC-U Multi-Layer Sewer & Drain SANS 1601

ULTRACOR PVC-U MULTI-LAYER OR STRUCTURED WALL SEWER & DRAIN PIPE SYSTEMS (SANS 1601)

Durodrain solid wall sewer & drain pipe Ultracor has smooth inner and outer walls separated by a dense cellular foam core. 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 SABS joining systems
  • Low pipe mass that contributes to competitive pricing and economic use
  • Ultracor carries the SABS 1601:mark of approval

Pipe Stiffness

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 (see below table).

From the table we see that a SANS 1601 structured wall 400kPa pipe has a greater pipe stiffness than a SANS 791 solid wall heavy duty Class 34 pipe.

SANS Specification Normal Duty Medium Duty Heavy Duty

SANS 791 51 100 - - 34 300

Codes of practice

Trenching, Bedding and Backfilling

For detailed information refer to the Durodrain Codes of Practice section.

Cutting & Jointing

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.

Cutting: Cut the pipe square with a cross cut saw or angle grinder depending on the pipe size. Clean away swarf. The pipe end must be chamfered again to 15 to ensure easy insertion when making a joint.

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 into the sand.

Lubrication: We have liquid lubricant and a jelly-like lubricant known as gel. Both products are designed for lubricating pipe seals. In order to make a leak-free joint effortlessly, use liberal amounts of lubricant, but avoid hang up and possible blockages.

Joints: 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.

Wrong

Handling
Pipes and fittings should not be handled carelessly, as this may cause damage. Pipe should not be dropped or dragged along the ground.

Storage
Pipes should be stored on level, flat ground, free of stones. They may be stored on timber supports of at least 75 mm 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.

Transportation

Transporation 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.
