Pressure Vessel

NASA-STD-8719.26A, NASA Requirements for Ground Based Non-Code Metallic Pressure Vessels went into effect May 11, 2021. This standard is intended to manage risk to personnel, facilities, missions and the environment posed by the use of existing ground-based, non-code metallic Pressure Vessels that either 1) do not comply with applicable American Society of Mechanical Engineers code requirements specified in Occupational Safety and Health Administration 29 CFR pt. 1910 regulations or 2) were modified and no longer comply with the code.

NASA Breakthrough in Multi-Layered Pressure Vessel NDE

2-minute read
PVS

The Office of Safety and Mission Assurance’s Multi-Layered Pressure Vessel Risk Mitigation Project (MLPVRMP) made significant advancements in detecting weld flaws in Multi-Layered Pressure Vessels (MLVP) through the use of advanced techniques in Nondestructive Evaluation (NDE). The unique design and fabrication of MLPVs made inspection of inner weld areas joining shell to shell layers impossible, until now. This breakthrough presents the agency with the ability to thoroughly examine and baseline in-service MLPVs for critical weld flaws, thereby supporting selective MLPV replacement based on verified risk.
