Hultec South Afrca Rieber Platinum Seal
The Rieber Platinum Seal modern generation, energy efficient sealing system for PVC pipes
HOW IT WORKS – PROPERTIES AND DESIGN FEATURES
By far the most popular jointing mechanism for municipal pipelines is by way of spigot and pipe-end socket which has made PVC the preferred material by consulting engineers, installation contractors and municipal end users. The popularity of PVC pipes can be attributed to the many advantages offered by this sealing system: the ease with which pipelines can be installed at relatively low costs, allowance for angular deflection at joints, allowance for axial movements according to temperature and pressure changes, and allowance for ground movements.
Rieber is a generic name used to describe a steel-reinforced rubber seal that is incorporated in the pipe socket during manufacture, making the seal an integral part of the pipe. Being firmly fixed in the pipe socket ring groove, the steel reinforcing provides structural support and pre-compression of the rubber ring against the pipe wall, as shown. The tight anchoring of the seal prevents the ingress of soil and other foreign particles into the sealing zones.
THE FASTEST GROWING PVC PIPE SEALING SYSTEM IN THE WORLD
The integrated Rieber sealing system has established a reputation as the most reliable PVC pipe jointing system in the world and is continuously increasing market share, presently as follows:
The Platinum seal is available in sizes from 50 to 1200mm and meets the requirements of SANS/EN 681-1, SANS 966 Parts 1 and 2, SANS 791 and SANS 1601.
PRESSURE VARIATIONS IN THE PIPELINE
Rieber’s design features provide exceptional hydrostatic strength, preventing the seal shifting during axial and frictional movements in the pipeline. These movements can occur under pulsating pressures caused by water hammer or pressure surges: Rieber’s design features prevent sand ingress and displacement under these conditions.
ENERGY AND WATER LOSSES
The fact that up to one third or more of potable water is lost in many cities and towns in South Africa represents an incalculable loss of this precious resource as well as the energy used in pumping it. Modern technology integrated, steel reinforced pipe seals, guarantee no leaks long-term, and are thus essential to water authorities and consumers.
