Technology Patent

The company has gathered experts in the fields of molding, welding, machinery, hydraulics, electrical automation and non-destructive testing to form a strong technical research and development team of more than 100 people; it has established laboratories for welding, CTOD, deep-sea annular crushing mechanics research, and supporting materials. More than 200 sets of testing equipment, including testing machines, low-temperature impact material testing machines and devices, 80,000-joule drop weight tear testing machines, computer-controlled chemical composition vacuum direct-reading spectrometers, and metallographic microscopes; independently developed welded pipes with internationally advanced levels Manufacturing process technology and mechanical equipment have solved key technical problems in the development of the industry such as material forming, welding, non-destructive testing, and material anti-corrosion, forming a core technology system with independent intellectual property rights, and excellently completed special steel pipes for deep-sea oil and gas transportation, and resistant The development of key new products such as corroded bimetallic composite pipes and X80~X100 high-strength and toughness steel pipes has laid a solid technical foundation for strengthening the company's characteristic products and services.

During this process, we pay special attention to the research and development and production of tubing and casing to ensure that they have excellent performance in deep sea and harsh environments. In addition, our seamless steel pipe and drill pipe series products perform well in oil and gas drilling, meeting customers' needs for high strength and high durability. Our drill collar products are well-known for their precise manufacturing process and high-quality materials and are widely used in various drilling operations.

Piling pipe is one of the important areas of our technology research and development. Through continuous technological innovation and optimization, we have developed high-performance piling pipe products suitable for various engineering projects. These products have significant advantages in corrosion resistance, strength and toughness, ensuring reliable application under various complex geological conditions.

Through continuous efforts, we have further enhanced the company's competitiveness in the market, enabling more potential customers to find and understand our core products such as tubing, casing, seamless steel pipe, drill pipe, drill collar and pile pipe. We will continue to adhere to technological innovation, continuously optimize products and services, and meet the diverse needs of global customers.
