[Case Study] Power Plant Elbow Piping Replacement Work
We would like to introduce an example of on-site piping replacement work that reduces management burdens!
We received an order for products for the replacement work of elbows with long seam welds, which we supplied several decades ago, for the after-service project at the Nagasaki Plant of Mitsubishi Heavy Industries, Ltd. for their thermal power plant. This project involved the on-site replacement of aging piping used under high temperature and high pressure conditions. However, instead of supplying the same elbows as before, we provided a new product that incorporates many advantages, which was well received. The specifications of the product that were appreciated are as follows: - Seamless elbows to eliminate long seam welds. - To reduce the workload within the engineering manufacturer, a hydraulic pressure test was conducted at Benkan Kiko at a pressure of 1.3 times the design pressure. - To facilitate easy replacement work on-site, lifting fixtures were installed. By conducting the hydraulic pressure test at 1.3 times the design pressure in advance at Benkan Kiko, we can avoid the risk of performing a hydraulic pressure test at 1.3 times the design pressure on aging piping. We have confirmed and experienced effects such as delivery management and workload reduction, and we have received high evaluations, including subsequent orders for after-service projects under the same scheme.
