Durocast: Chemical & Acid Resistant Products in the Heart of the Vaal Triangle
The Vaal Triangle concentrates some of South Africa’s most aggressive chemical environments within a short drive: the Sasolburg chemical and fertiliser cluster, with its acid production and process plants, and the Vanderbijlpark steelworks, where strip is pickled in acid before cold rolling.
Durocast (Pty) Ltd manufactures its chemical and acid resistant products in Vereeniging, inside the Vaal Triangle itself — so plants here get material, test work and technical support from a supplier on their doorstep.
Acid Gas Is as Destructive as Acid Liquid
In acid plants and pickling lines, much of the damage is done by vapour and condensate rather than by liquid spills. Stacks, ducts, breechings, scrubbers and precipitators carry acid-laden gas that condenses on cooler surfaces and eats into unprotected concrete and steel. These are exactly the monolithic linings Acicrete and Acispray are designed for — especially for nitric, hydrochloric, phosphoric and sulphuric acids.
The Durocast Products Vaal Plants Rely On
Vaal orders centre on Acispray 1S gunned linings for stacks and ducts, Acicrete 1S for scrubbers, tanks and process vessels, Aciset 1S mortar for brick and joint work, and the economical Acicrete 1 range where conditions allow. See the full range on the Chemical & Acid Resistant Products page.
Where Durocast Products Are Used in the Vaal Triangle
- Acid-plant stacks and ducts — Acispray 1S gunned linings.
- Scrubbers and precipitators — monolithic Acicrete linings.
- Pickling-line surrounds — floors, bunds and trenches near hydrochloric-acid baths.
- Process vessels and tanks — linings, with a membrane where recommended.
- Chemical-plant floors — monolithic toppings instead of acid brick and tile.
The Vaal Triangle Industries Durocast Serves
From Sasolburg to Vanderbijlpark and Meyerton, Durocast protects:
- Petrochemicals and chemicals — Sasolburg process plants.
- Fertiliser and acid production — nitric and sulphuric acid duty.
- Steel — Vanderbijlpark pickling and finishing.
- Power and utilities — flue-gas ducts and stacks.
- Food and beverage — processing plants around Meyerton.
Test Work Done Down the Road
Because the factory and its test facilities are local, Durocast can test samples against your actual process liquor or condensate and visit site to inspect a failed lining. Read more about the company on our About Us page.
