Lotte Engineering Wins South Korea Certification for Quake-Resistant Fire Piping Brace

Lotte Engineering & Construction said Tuesday that a quake-resistant firefighting piping technology it co-developed with Doosan E&C, HL D&I Halla and MakeSoon has received a construction new-technology certification from the Ministry of Land, Infrastructure and Transport (No. 1043).
 
The technology, an integrated four-direction anti-sway brace for vertical and horizontal piping, is designed to prevent damage to firefighting pipes during earthquakes. The company said South Korea’s market for seismic bracing of firefighting piping has relied entirely on imported products, and the new system represents successful localization and domestic production.
 
Under conventional two-direction bracing, pipes located away from the brace could be damaged by leverage effects. The new design combines two braces into a single integrated device, supporting the pipe in four directions at the same time and significantly improving seismic performance, the company said.
 
Lotte Engineering said the method also showed environmental and cost benefits. For an underground parking garage in a 500-household apartment complex, it can reduce installation points to 25 from 39 under existing methods. It also cuts carbon dioxide emissions by about 51% and reduces raw material use by about 50%, it said.
 
The company said the technology has also received related certifications, including designation as a disaster-safety new technology (NET) and green technology certification. It has been applied at multiple sites, including Hadan Lotte Castle and Seomyeon Lotte Castle Eluce, and Lotte Engineering said it plans to expand use nationwide, including at Munhyeon Lotte Castle Infiniel and Daejeon Lotte Castle The First.
 
“Localizing a seismic technology that had a high dependence on overseas products and maximizing safety is highly meaningful,” a Lotte Engineering official said. “Because it is an innovative, eco-friendly method that reduces material use, we will continue to expand on-site applications.”
