Hardened Polymer Explosion: Safety Disk Failure

The rupture of the safety disk in a polymer manufacturing reactor triggered a controlled explosion that could have been catastrophic. The cause: an obstruction from hardened plastic product that blocked the relief pathway. We analyze the case using FARO Scene for 3D scanning and COMSOL Multiphysics for flow and pressure simulation.

Digital reconstruction with FARO Scene and simulation in COMSOL 🔧

The forensic team used FARO Scene to generate a point cloud of the reactor and the explosion zone. With this data, the fluid dynamics and pressure buildup were modeled in COMSOL Multiphysics. The simulation revealed that the solid polymer obstruction in the disk discharge line raised the internal pressure to the breaking point. The analysis allowed identifying the exact accumulation zone and the critical thickness of the hardened material.

The polymer said: I'm not going out that way 💥

The hardened plastic decided to stay put in the pipe, forming a plug so solid that the safety disk preferred to burst rather than argue with it. The moral is simple: if your polymer becomes stubborn, don't trust a safety disk to convince it. Better to inspect the discharge lines with a 3D scanner before the reactor decides to put on a show of force.
