"sealing failure" is correct and usable in written English.
You can use this phrase to refer to a type of mechanical failure, when something intended to seal something else is not functioning properly. For example, you could use the phrase in the following sentence: "The sealing failure in the car's engine caused the oil to leak out."
Mainly due to an unreasonable selection of rubber material for elastomeric packing element, sealing failure commonly occurs in compression packer in the field.
For injection & production well built in underground gas storage (UGS), sealing failure of cement sheath is one of the major factors threatening wellbore integrity due to continuous varied casing pressure and temperature.
Before the optimization, there is a gap on the upper part of the sealing surface, and the effective contact width is only half of design width, which trends to cause sealing failure under the complicated subsea environment.
Sealing failure may cause sensing problems or short circuits.
CO2 corrosion on rubber materials can cause sealing failure accidents and induce sustained casing pressure, thus affecting safety production of the injection wells in enhanced oil recovery (EOR) operations.
With the lake gate sealed, failure of the 17th Street canal walls – so important in the last disaster — would not have been as dire a situation as it was in 2005, when the canal became an open conduit for Lake Pontchartrain to spill deep into the city.
It is found that the tandem seal arrangement offers a significant reduction of leakage (in the order of 50% or more) compared with the single-seal configuration and that the interseal pressure remains low until the time when it rises abruptly to high value, even exceeding the sealed pressure and risking seal failure.
However, sealing structure failure (SSF), which leads to the leakage of reactant gases, often occurs in the assembly process or start-up operation for PEMFCs.
Quality-brand windows are usually under warranty against seal failure.
A seal failure is often diagnosed through visual inspection of the failed seal's components.
Polymerizing monomer means a compound which may form polymer buildup in pump mechanical seals resulting in rapid mechanical seal failure.
