Chengdu Ruiyang Zhizao Technology Co., Ltd.

Chengdu Ruiyang Zhizao Technology Co., Ltd. (成都锐炀智造科技有限公司) is a Chinese manufacturer of rotary drill stem elements and associated threading and gauging products for the oil and gas drilling industry. The company is headquartered within the Sichuan Jintang Industrial Park in Jintang County, Chengdu, Sichuan Province, and was established in August 2020. Despite its relatively recent founding, the company has achieved full API Monogram Program certification under three separate specifications: API Spec 7-1 (Rotary Drill Stem Elements, license 7-1-1750), API Spec 7-2 (Threading and Gauging of Rotary Shouldered Connections, license 7-2-1245), and API Spec Q1 (Quality Management System, license Q1-5012). This combination of 7-1 and 7-2 certifications indicates the company both manufactures drill stem components (drill pipe, drill collars, heavy weight drill pipe, kelly, subs, and stabilizers) and produces the threading and gauging tools used for rotary shouldered connection inspection. The API Q1 quality management system certification underpins the company's commitment to documented quality assurance processes across all product lines. Core manufacturing capabilities are focused on drill pipe and drill collar fabrication, rotary shouldered connection threading and machining, and the production of thread gauges and inspection tooling for rotary shouldered connection profiles including NC, IF, regular, and full-hole thread forms. The Jintang County industrial base in Chengdu places the company within a well-established manufacturing corridor in Sichuan Province that serves China's major oilfield operators including CNPC, CNOOC, and Sinopec. Registered capital is reported at 10 million RMB, indicating a small-to-mid-size manufacturing operation. The company is managed by legal representative Yang Dongquan (杨东泉). Products are suitable for export and target both domestic Chinese oilfield markets and international drilling markets requiring API-certified drill stem equipment.
