A premier structured-wall, lightweight piping solution, corruDUCT™ is engineered for maximum versatility across telecommunications, electrical, agricultural, and civil engineering projects. Its design balances structural strength with ease of handling.
Description
The corruDUCT™ range offers a robust selection of ducting solutions, meticulously designed to meet specifications outlined in SANS 61386-24 Class N. All pipes in this range are specifically marked as Class N, signifying their high crush resistance of over 250N for the 50m and 1250m coils and 450N for the 6m lengths. These ducts are available in 6-meter lengths, 50-meter coils and customized coils up to 1 250 m ensuring versatile application and installation options tailored to diverse requirements. Each length or coil is supplied complete with couplings, typically one coupling per length but additional couplings are available, detailed in the accompanying tables. Manufactured under strict quality control guidelines, our products adhere to rigorous standards of the UNI EN ISO 9001:2015 certified Quality Management System.

Specs and techs: corruDuct™ HD
Description:
The corruDUCT™ HD range offers robust ducting solutions designed for applications requiring high stiffness. These ducts are meticulously engineered to meet the specifications outlined in SANS 21138-3. Manufactured in 6-meter lengths, each duct features a “bell end” to eliminate the need for separate couplings, although a plain-ended configuration with separate couplings is also available. Produced under strict quality control guidelines, our products comply with the rigorous standards of the ISO
9001:2015 certified Quality Management System.

Application for drainageDUCT™
Slotted piping represents the most effective and economical solution to the increasing challenges of:
Advantages of drainageDUCT™
Dispersion piping for flow control:
Existing sewer and drainage systems are encountering growing difficulties in coping with the collection and dispersion of rainwater run-off.
This problem is particularly serious in towns and cities. The rapid of built-up areas has dramatically altered the ratio between rainfall volume and drain capacity, partly as a result of higher flow rates entering the drains, but often as a result of the inadequacy of drainage systems originally designed and built to cater for urban expansion on a far smaller scale.

drainageDUCT™ for soil drainage
In high rainfall areas, degradation (i.e. loss of the soil’s natural physical, mechanical, chemical and biological properties) can lead to soil becoming unable to absorb rainwater, with the risk of hydro-geological instability. One of the ways to prevent the phenomena that eventually leads to subsidence and landslides, is to limit the amount of excess water in the soil.

Installation in different applications.
Agriculture: In agricultural applications it is common practice to use drainage pipes with a single filter consisting of sand or stone. Fines will migrate through the filter into the pipe. These fines are deposited and build up over time in pipes with rough or corrugated inner bores. This necessitates periodic flushing to remove the deposits and maintain the integrity of the drainage system. However, if drainageDUCT™, with its smooth bore, is installed at the correct gradient, the system will be self-cleansing.
Structural: In structural applications, such as underfloor drainage of reservoirs, drainageDUCT™ is used with a filter of no fines concrete. The strength of drainageDUCT™ has a distinct advantage as it is not easily damaged during concrete pouring operations.
Civil Engineering: A double filter consisting of stone and geotextile is most used in civil engineering applications. For a well-designed filter to function a reverse filter must form between the soil and the geotextile, allowing fines to pass into the drainage system. The use of properly installed smooth bore drainageDUCT™ will ensure the efficient removal of these fines. Stability of the filter will occur when the movement of fines has ceased.
