- AI summary (β)
- A letter (reply) dated May 18, Taishō 5, from Yamamoto, Head of the Outfitting Factory, to the Chief Supervisor for New Ships, reporting the results of an investigation concerning corrosion of seawater pipes (copper pipes) aboard the warship Hiei and their repair and modification. It records the locations and forms of corrosion, the cutting out of corroded sections and “acetylene” welding, countermeasures using cast-iron “pieces” and “zinc boxes,” and analytical results for corroded pipes from Hiei and Haruna, and states the opinion that the cause was electrical action such as current leakage. Haruna, Kongō, and Sasebo Naval Arsenal are also mentioned. Received May 19, Taishō 5. Keywords: Hiei, Haruna, Kongō, seawater pipes, corrosion, copper pipes, zinc boxes, cast-iron pieces, current leakageAuto-generated by Azure OpenAI gpt-5.5 from OCR text (which may contain errors) and image captions.
