TECHNOLOGY Blasting Water jetting can also be used to remove road markings. In addition to those for hydrodemolition, Total Blasting’s product stable includes tools for water- jet cutting of steel and concrete. Refinery shutdowns Total Blasting supplied its specialised high-pressure pumps and associated tooling for the cleaning of plant and equipment at Sasol’s Secunda refinery plant during its critical annual shutdown in September last year. The contractors commissioned to undertake the industrial cleaning also had used Total Blasting for the annual shutdowns of the Sapref & Chevron refinery in Durban and Cape Town, earlier in the year, and once again turned to the company’s reliable rental fleet, available through sister company Total Site Solutions. Deemed one of the largest shutdowns of its nature in the world, the Sasol Secunda refinery shutdown has been a prominent annual event since it started in the early 1980s. The planned shutdown took place over a 14-day period to facilitate routine cleaning, critical path maintenance, and essential mechanical plant repairs. With Sasol contributing approximately 29% of the South African fuel pool, minimising non-production time is crucial to ensure an uninterrupted supply of fuel in the country. Total Blasting supplied its 1 000- bar and 2 800-bar units with flow rates ranging from 60 to 120ℓ/min and 19ℓ/min, respectively. “As a provider of high- pressure cleaning solutions in an industry with a number of other vendors, it is the reliability of our equipment that makes us the first-choice option. This is especially true in refinery shutdown applications where equipment needs to run without any breakdowns to ensure maximum uptime for the timely completion of the task at hand,” Storer explains. ■ Water jetting can be used in place of sandblasting, with UHP water — 2  800 bar — being used to strip any coating, contamination, or debris from a steel substrate. Specialised high-pressure pumps and associated tooling are used for cleaning plant and equipment across a range of industries. “Hydrodemolition is in its infancy in Africa. The success of this project opens up opportunities for hydrodemolition and water jetting in the southern African concrete repair sector.” JANUARY 2018 23
