 · It is generally accepted, for example, that a major objective of faying-surface sealing is corrosion control. The faying-surface seal is not considered to be a primary fuel barrier seal, except in adhesive-bonded systems; the faying surface seal, however, does play an extremely important role as a secondary fuel barrier seal.

 · meable faying-Surface Seal, the Selection of faying-Surface Sealant materials increases dramatically and Sealant materi als, which exhibit relatively superior characteristics, such as resistance to deterioration, resistance to Solvent attack, and resistance to elevated or depressed temperatures, may be used.

 · In the world of seals, surface roughness is typically used to describe the finish condition of a sealing surface. The Roughness Average ( Ra) value is most commonly used parameter, expressed in micro inches or micrometers. The …

A faying surface is one of the surfaces that are in contact at a joint. Faying surfaces may be connected to each other by bolts or rivets, adhesives, welding, or soldering. An example would be steel pipe flanges, in which the connected ends of …

With painted faying surfaces, the slip resistance is determined by the tested performance of the paint system as meeting Class A, B, or some other intermediate slip coefficient and …

What is a Class A faying surface? 8 were updated to revise the class for hot-dip galvanized faying surfaces, and include options for metallized faying surfaces and blast-cleaned surfaces coated with zinc-rich paints: Class A: Unpainted clean mill scale and blast-cleaned surfaces with Class A coatings. Class C: Hot-dip galvanized surfaces.

The fay surface sealant 16 may be applied by brush, sprayer, to other suitable means, and in some embodiments is applied to a maximum thickness of 0.010" (0.254 mm). The fay surface sealant 16...

Note that while the application time of a faying-surface sealant may be only 8 to 48 h, the assembly time can be 20 to 336 h (or 2 weeks), depending on the formulation of the particular Class C sealant. B BACKUP SEAL A seal on the dry side of the fuel tank.

The objectives of this project are to determine the slip performance of friction-type connections under the influence of over-spray on the faying surfaces, and incomplete masking of the faying surfaces. The experimental project involved the testing of 65 specimens consisting of three identical plates.
