As an important material for modern industry, large-diameter welded pipes are undergoing an innovation in their application fields. With the advancement of manufacturing technology and breakthroughs in materials science, the application scope of large-diameter welded pipes has expanded from the traditional oil and gas transportation field to emerging fields such as new energy transportation, marine engineering and super-high-rise buildings, showing great development potential.
1. Breakthrough of large-diameter welded pipes in the field of new energy transportation
In the field of hydrogen energy transportation, large-diameter welded pipes are playing a key role. As a clean energy, hydrogen energy has higher requirements for pipeline materials. The new X80 and above large-diameter welded pipes adopt special alloy design and advanced welding technology to effectively prevent hydrogen embrittlement and ensure the safety and economy of hydrogen transportation. In the carbon dioxide capture and storage (CCS) project, large-diameter welded pipes also play an important role. Its excellent corrosion resistance and pressure bearing capacity provide reliable guarantee for large-scale carbon dioxide transportation.
2. Innovative applications in marine engineering
Deep-sea oil and gas development poses severe challenges to pipeline systems. Large-diameter welded pipes have significantly improved their corrosion resistance and compressive strength by adopting bimetallic composite technology and special coating technology. In the field of offshore wind power, large-diameter welded pipes are innovatively applied to single pile foundation structures. Its excellent mechanical properties and machinability provide stable and reliable foundation support for offshore wind power facilities.
3. Application of super-high-rise building structures
In the field of super-high-rise buildings, large-diameter welded pipes are changing the traditional design concept of building structures. By adopting high-strength steel and optimizing welding processes, large-diameter welded pipes can meet the stringent requirements of super-high-rise buildings for structural strength and safety. In terms of seismic design, large-diameter welded pipes have significantly improved the seismic performance of building structures through special node design and material selection.
