Nastoah, a manufacturing subsidiary of Nippon Yakin Kogyo, consolidated 2 heat-treatment furnaces into 1 at its factory in Chigasaki, Kanagawa Prefecture, and invested approximately ¥300 million to install equipment that improves energy efficiency. Annual CO2 emissions are expected to be reduced by approximately 319 tonnes, representing a reduction of approximately 15%.
Nastoah consolidated the 2 heat-treatment furnaces used to manufacture stainless-steel and nickel-alloy pipes into 1. The factory is located in Chigasaki, Kanagawa Prefecture, and the investment is reported to have totaled approximately ¥300 million.
The new equipment recovers waste heat for reuse in heat treatment and improves insulation, thereby increasing energy efficiency. This is expected to reduce CO2 emissions by 319 tonnes per year.
At the upgraded factory, the process for manufacturing welded pipes, made by forming stainless steel into a round pipe shape, has entered full-scale operation.
