CSIR develops polymer composite for steel pipe maker for push-fit applications

The Council for Scientific and Industrial Research (CSIR) has developed a polymer composite solution for, and in partnership with, steel pipe manufacturer Hall Longmore.

The solution advances Hall Longmore's aim to offer the South African water industry a localised push-fit application for pressurised steel pipelines.

Using the Department of Science and Innovation-CSIR Nanomaterials Industrial Development Facility, CSIR researchers developed a formulated polymer composite material for Hall Longmore and performed coating trials.

“The coating trials proved to be a success and an indication of a fruitful collaboration between local institutions working together to localise technology solutions for industry,” says Hall Longmore MD KC van Rooyen.

South Africa-based Hall Longmore has up to now been importing a special polymer to coat pipes through a fluidised-bed technology. However, fluctuations in the dollar:rand exchange rate made it increasingly challenging to budget for projects.

In response to this, Hall Longmore approached and contracted the CSIR to develop a composite material from locally produced polymers.

“We have expertise in formulation design, polymer modification, processing and characterisation and an array of other capabilities that we leverage to provide our clients with a holistic solution,” says CSIR advanced polymer composites research group leader Dr Vincent Ojijo.

“This created a conducive environment for us to co-design and construct a test-rig with Hall Longmore. The project procured services from a local third-party polymer compounder for successful industrial optimisation and production of test materials at scale.

"The ultimate success of this project is credited to a strong collaborative and consultative effort by the parties,” he says.

The CSIR undertook preliminary research that outlined the desired developmental approach to be taken. This was followed by laboratory-scale material development and the technical validation of its performance.

Concurrently, a laboratory-scale fluidised bed for rapid coating trials was co-designed by the CSIR and Hall Longmore.

The company co-constructed, installed and commissioned it for use in testing the developed material. After successful laboratory-scale validations, the pilot-scale optimisation process for the developed material was completed.

The project is now in the production phase at the third-party compounder, with the steel-pipe supplier having ordered 150 t of the CSIR co-developed material.

“One of the CSIR’s strategic objectives is to collaboratively improve the competitiveness of high-impact industries to support South Africa’s re-industrialisation; therefore, the successful collaboration between the CSIR and Hall Longmore shows our commitment to supporting South Africa’s industry and growing our impact on the continent and around the world,” says CSIR Future Production Chemicals cluster executive manager Dr Jan van de Loosdrecht.
