Recent accidents have led to new standards for blast and fire resistance of buildings on hazardous zones. Often a peak side-on overpressure of 55kPa is required, resulting in a reflected blast overpressure of 1.32 (20 PSI)
InterDam Merford addresses these new requirements with her tested and certified Blast- and fire resistant doors-, walls and windows. (See picture) InterDam Merford has solved blast safety problems for the following projects: NAM Groningen Gas Field, Shell Qatar Pearl GTL Project and Shell and BP Rotterdam Refineries.
Blast relief Walls and Hatches
InterDam Merford also provides blast relief walls and blast relief hatches
Blast relief walls and blast relief hatches are often fixed with break bolts. A break bolt is a fastener that breaks when subjected to a pre- determined load.
More reliable fixings for this kind of walls are those that collapse by bending open; that is at the load whereby the yield point is reached. IDM offers both types of fixing methods.
InterDam Merford helps you on all your queries on Blast relief; from a blast relief hatch to a blast relief wall.
