Heibei Constellation Energy Technology Co., Ltd. is a leading professional manufacturer and supplier of well control equipment, with a core focus on blowout preventer (BOP) products and comprehensive well control solutions. Founded 5 years ago on the principle of "safety first, quality paramount," we have rapidly established ourselves as a reliable partner for the global oil and gas exploration, drilling, and production industries. Over the past five years, we have successfully served numerous overseas clients, accumulating ample practical experience in meeting global market demands and international technical standards.

Our technical team is the backbone of innovation and quality assurance. We employ 3 senior technical engineers and 5 professional engineers—all with 15 to 20 years of dedicated experience in the BOP and well control equipment sector—specializing in mechanical design, hydraulic systems, and quality control. Supported by skilled employees with comparable industry tenure, this expert workforce enables independent R&D, customized product development, and full compliance with standards such as API, GB, and ISO, ensuring our products’ reliability and advanced performance.

To meet growing market demand and ensure efficient supply chain management, we operate three modern manufacturing bases. Two bases in Hebei focus on the R&D and production of BOPs, BOP accessories, and BOP control systems; the Jiangsu base specializes in manufacturing manual gate valves, hydraulic gate valves, and choke & kill manifolds. All bases are equipped with advanced machining equipment, precision testing instruments, and strict quality control processes, covering the entire production chain from raw material processing to final product inspection.

We offer a complete portfolio of well control products for the full drilling and production cycle: BOPs (annular, ram, and combination BOP stacks); BOP accessories (rams, packing elements, bonnets, connectors); BOP control systems (hydraulic control panels, accumulator units, remote control systems); API 6A-standard gate valves; choke & kill manifolds; and auxiliary equipment (sand separators, desanders, wellhead accessories). All products undergo rigorous testing (pressure, fatigue, corrosion resistance) to ensure reliable performance under extreme working conditions—validated by our extensive international project experience.

Combining our technical team’s decades of industry expertise, advanced production capacity, proven international project experience, and customer-centric service, we deliver:

• Safe, durable, high-performance well control equipment;
• Customized solutions aligned with specific project requirements and global technical standards;
• Prompt technical support and after-sales service backed by rich practical experience;
