Hirohisa Kitamura has been named a sales manager for marine products for Kubota America Corporation, New York, a wholly owned subsidiary of Kubota, Ltd. of Japan. He had been assistant chief, castings and industrial, Machinery Export Department, for Kubota in Tokyo.

Hiroshi Ito, president, Kubota America, said the company is expanding its sales force as a result of increasing business from Kubota's KCP line of cargo oil pipe. Mr. Kitamura will assist Y. Seo, Kubota America's vice president for marketing.

The KCP series has been installed in more than 500 Japanese-built tankers over the past 20 years and, since 1975, Kubota has also been marketing the product worldwide as a replacement for conventional pipe.
