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.

Clifton Arnold

When asked about his new Safety and Mission Assurance (SMA) role, Clifton Arnold joked that it came with many hats — in fact, more hats that he ever expected.

“The position expanded,” explained Arnold. “Pressure Systems included ground and flight pressure systems. With that, Lifting Devices was added, and then we included a special category called Propellants and Pressurants that deals with all propellants and inert gases.
