SPF (Seismic Steel Pipe for crossing Fault) Ground-settlement Type, a special seismic steel pipe capable of absorbing large ground settlement during seismic events which was developed by JFE Engineering Corporation (President and CEO: Hajime Oshita, Head Office: Chiyoda-ku, Tokyo), has been selected for use in the new outfall pipeline of the Annacis Island Wastewater Treatment Plant planned by Metro Vancouver *1 in Canada. SPF is an proprietary product of JFE Engineering. By creating easily-deformed convex wave-shaped sections, it can secure water transmission function without cracks or leaks, even in a case of ground displacement of several meters caused by an earthquake.
Metro Vancouver area is located in a seismic zone near the boundary between two plates and has experienced numerous earthquakes of magnitude 7 or larger in the past. For this reason, Metro Vancouver is promoting constructions and improvements of facilities that can withstand large-scale earthquakes at a rapid pace including the Annacis Island Wastewater Treatment Plant. These developments are important infrastructure for the citizens' daily life. SPF will be used as part of the outfall pipeline (diameter: 2,550 mm) at the Annacis Wastewater Treatment Plant in a section where ground displacement of as much as 1.7 meters is feared in an earthquake.
In Japan, the SPF Ground-settlement Type has already been adopted by Hokuriku Regional Agricultural Administration Office and Hokkaido Regional Development Bureau, and has acquired a high reputation as a product that contributes to a resilient infrastructure. As a leading company in the field of water steel pipe, JFE Engineering has manufactured a large number of water steel pipes to date, including the SPF Ground-settlement Type. In winning this order, the track records of SPF Ground-settlement Type in Japan and its engineering capabilities to design and manufacture diverse types of steel pipes were highly evaluated.
In the future, JFE Engineering will continue to contribute to safe and secure foundation for life around the world, by applying leading-edge engineering technology.
- *1 Metro Vancouver is a regional governmental district consisting of 23 local governments including the City of Vancouver.
