COVER STORY
The plastic pipe innovators For over three decades, Pexmart has led the way as a manufacturer, OEM supplier and turnkey installer of HDPE, LDPE and PVC plastic pipe systems in South Africa, and across Africa. Expertise in detailing, costing, construction and project management, delivery and installation meet the exacting specifications of the agricultural, building, commercial, industrial, mining and municipal sectors.

eading through technology and a winning team approach, Pexmart continues to build on its reputation as a multifaceted specialist providing tailored solutions for the local and international markets. Irrespective of the project scale, the focus is on efficient and cost-effective execution in the fields of manufacturing, installation and maintenance. Growth is being sustained by a dual-pronged focus on public and private sector clients. Forming part of its expansion strategy, Pexmart concluded the acquisition of Spiral HDPE Pipe’s operations in 2018. This was followed in 2019 by the acquisition of Marley Pipe Systems’ HDPE and FLEX plant in Rosslyn, Gauteng. A member of the Southern African Plastic Pipe Manufacturers Association (SAPPMA), Pexmart adheres to and fully supports SABS and SAPPMA’s Quality Assurance Programme. Products are manufactured to meet highand low-pressure ratings. Alongside pipe systems, these include the PEX-FLEX range of

flexible hoses specially developed for a wide range of applications, including domestic, firefighting, irrigation, industrial and mining. “HDPE solid wall pipe has been used in potable water, sewer and mining for many decades and is rapidly growing as the preferred material for pipe lining and relining, slurry applications and for use in dolomitic areas,” explains Andre Janse van Rensburg, CEO, Pexmart. “HDPE is also increasingly the preferred choice for municipal water and wastewater projects.” We can manufacture pipe sizes ranging from 16 mm to 1 000 mm (HDPE) and 300 mm to 3 500 mm for spiral structured wall pipe that can be welded.
Spiral HDPE pipe The key advantage of the spiral range is that the corrugated design provides superior ring stiffness and rigidity while using less material in the manufacturing process compared to sold wall pipes. Providing a more cost-effective solution, they are well
suited to applications like culvert stormwater management and gravity trunk sewer mains. Other custom fabricated spiral HDPE products include manifolds, manholes, tees and reducing fittings.
Mining and municipal The ability to fabricate to demanding production timelines and specifications is underscored by the fact that Pexmart has ongoing supply and installation contracts in place within the mining sector. These include a five-year contract with Debswana Diamond Company, plus contracts with Royal Bafokeng Resources, and Anglo American Platinum.
