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.
The company has successively established innovative scientific research institutions such as postdoctoral scientific research workstations, national enterprise technology centers, and academician workstations. It has undertaken more than 20 major national, provincial, and municipal scientific research and innovation projects, and has obtained 55 Class I patent authorizations, 138 Class II patent authorizations, and Hosted or participated in "Straight-seam electric welded steel pipes" (GB/T 13793-2008), "Welded steel pipe dimensions and unit length weight" (GB/T 21835-2008), "Welded steel pipes for low-pressure fluid transportation" (GB/T 3091 -2008), "Welded Pipe Process Design Specifications" (GB50468-2008), "Long Seam Submerged Arc Welded Pipes for High Temperature and High Pressure Pipelines" (GB/T 32970-2016), "Steel Pipes for Marine Engineering Piles" (GB/T 37636-2019 ) and the formulation and revision of many national standards.
