TECHNOWRAP™ CASE STUDIES
Pipeline and composite repair case studies
24" natural gas line, live repair
Refinery, South Africa. Through-wall defect repaired in 15 hours with the line in service. 14 layers of Technowrap SRS, 20-year design life.
30" gas line, 0.74 mm wall
Refinery, South Africa, 2022. 21 m of severely thinned line reinforced live with 11 layers of Technowrap SRS at 47 bar.
30" cooling water T-section
Refinery, South Africa. Internal erosion left 3.37 mm of wall. Eight layers of Technowrap 2K installed in 10 hours.
Condenser end dome repair
Refinery, South Africa. 895 mm stainless steel dome with through-wall stress corrosion cracking, repaired with 10 layers of Technowrap 2K and a heat-accelerated cure, giving a one-year life extension.
20" salt water coupling repair
Refinery, Mossel Bay. Water hammer caused recurring leaks and seepage towards town. The coupling was enclosed in a cage of 4 mm plate, tapered with fast-acting cement, then wrapped with Technowrap. Both underground couplings were repaired in place in two days.
