Specifications and Manufacturing Controls for LSAW Steel Pipes Suitable for Hydrogen Transmission
Hydrogen transmission imposes heightened demands on pipeline materials regarding impermeability, weld quality, and resistance to hydrogen embrittlement. Submerged arc welded (LSAW) steel pipes are typically employed as the primary solution. Such pipelines predominantly utilise carbon steel grades API 5L X52, X60, and above, with common external diameters ranging from DN300 to DN1200. Wall thicknesses are controlled between 8–30mm based on design pressure and safety factors. During manufacturing, Huayang prioritises controlling forming precision, the quality of internal and external submerged arc welds, and comprehensive non-destructive testing throughout the process. This ensures weld continuity and uniformity of the pipe body microstructure, meeting the long-term sealing and structural stability requirements demanded by hydrogen media.
Application Scenarios and Engineering Adaptability in Hydrogen Infrastructure
LSAW steel pipes are extensively deployed in hydrogen supply chains for long-distance transmission pipelines, hydrogen production facility export lines, and main networks within hydrogen demonstration zones. They are particularly suited for medium-to-high pressure applications and cross-regional installations. Depending on project requirements, these pipes can be equipped with internal friction-reducing coatings and external 3PE or FBE anti-corrosion systems to withstand buried or complex environmental operating conditions. Huayang Steel Pipe possesses extensive supply experience in energy pipeline sectors. We provide specification customisation, quality documentation, and technical coordination in accordance with hydrogen transmission project design parameters, fulfilling the comprehensive requirements for safety, standardisation, and long-term operational reliability in hydrogen engineering.
