Kelvion turns up the heat to produce massive 316 column for SA’s petrochemical industry member news
I n terms of the manufacture of the large stainless steel column, the fitment of internal tray rings and trays was completed in Kelvion’s 14 863 m² Germiston-based workshop and represented 30% of the overall mass of the column. The project took approximately eight months, and the team were under pressure to produce the complex piece of equipment in a tight timeframe to their normal world- class standards. Explaining the complexities of the fabrication of this high pressure piece of equipment Kelvion MD Alex Dreyer Sassda member Kelvion Services recently manufactured a large stainless steel column for a local petrochemical company from ultra resilient, top-of-the-range 316 stainless steel. This challenging project stems from its decades- long, specialist supply of locally designed and manufactured heat exchangers, pressure vessels, and cooling towers to the local industry.
explains; “The 54m long column had a large diameter of 3m, a sizeable length-to diameter-ratio as well as a hefty total mass of 100t, all of which were combined with the challenge of thin walls. This presented a number of handling issues in our works and during transport.” The true scale of the project became clear when the completed column was transported to the site on steerable, self-levelling multi-axle trailers over a distance of 185km and a total drive time of 14 hours. Depth of experience Fortunately, the depth of Kelvion’s experience and knowledge allowed it to successfully complete this project. This is evidenced by its long history given that Kelvion Services started operations in South Africa in the 1970s as GEA Aircooled Systems, which was part of the German-based GEA Group. From the 1980s Kelvion has also supplied air-cooled heat exchangers, shell and tube heat exchangers, pressure
