20 years of moving forward with PVC pipe technology | Infrastructure news

Celebrating its 20th birthday this year, Sizabantu Piping Systems has grown from a trading company to one providing the marketing and sales function for a major South African thermoplastic pipe manufacturer – Molecor.

About 40 years ago, PVC-O (oriented unplasticised polyvinyl chloride – SANS 16422) was developed. The molecular orientation process results in the improvement of physical and mechanical properties of the material. In the intervening 40 years, there have been improvements in PVC-O material: from Classification 315 material initially to Classification 500 material currently – the nomenclature represents 10 times the MRS (Minimum Required Strength) of the material.
