The petroleum industry field is the core of today's industries. The United States industry, which leads the global market, requires very strict quality management for all machinery components related to oil field development and petroleum refineries. API (American Petroleum Institute) is an institute responsible for setting standards and qualifying in accordance with these standards.
We, at Daido Kogyo Co., Ltd. obtained this certificate for industrial machinery chains in 1972. Since then, in compliance with API's strict quality management system we have delivered our D.I.D products to domestic and foreign customers, as well as the U.S. market.
