What is BS EN 3278 - Protruding head tubular sleeves about?
BS EN 3278 is a European standard on aerospace series that covers sleeves, tubular, protruding head, in corrosion resisting steel, passivated.
BS EN 3278 specifies the characteristics and technical requirements for protruding head tubular sleeves, in corrosion resisting steel, which may be plain or provided with a series of annular grooves.
Who is BS EN 3278 - Protruding head tubular sleeves for?
BS EN 3278 on protruding head tubular sleeves is useful for: 
- Aerospace parts manufacturers
- Protruding head tubular sleeves manufacturers
Why should you use BS EN 3278 - Protruding head tubular sleeves?
Stainless steel is known for its corrosion resistance in many environments in which carbon and low-alloy tool steels would corrode. The corrosion resistance is a result of a very thin (about 5 nanometers) oxide layer on the steel’s surface. This oxide layer is referred to as a passive layer since it renders the surface electrochemically passive in the presence of corrosive environments.
Passivated sleeves are for use in aerospace assemblies whose maximum operating temperature does not exceed 650 °C. The operating temperatures for aluminium pigmented sleeves should not exceed 230 °C.
With the use of BS EN 3278 you get to know the characteristics and technical requirements of protruding head tubular sleeves which can be very helpful for use in aerospace series.
