scope:

This SAE Aerospace Standard (AS) covers medium-pressure, high-temperature, flexible, metal-hose assemblies suitable for operation in pneumatic systems up to 800 °F with excursion to 1200 °F for Class "B" and "N" and primarily for use on jet aircraft power plants. Refer to 1.2.1 for recommended usage.

Types

a. Type 1: Convoluted helical inner tube, seamless or welded and redrawn tube material.

b. Type 2: Convoluted annular inner tube, seamless or welded and redrawn tube material.

c. Type 3: Convoluted helical inner tube, as-welded tube material.

d. Type 4: Convoluted annular inner tube, as-welded tube material.

NOTE: Unless otherwise specified on a design activity controlled drawing, or contract, Type 1, Type 2, Type 3, or Type 4 inner tube construction may be supplied.

Classes

Hose assemblies furnished under this document may be of the following classes. If no class is defined the class "S" shall be utilized.

a. Class "A": Corrosion resistant Type 321 convoluted inner tube and nickel alloy Type 625 or 718 fitting components.

b. Class "B": Nickel alloy Type 625 convoluted inner tube and nickel alloy Type 625 or 718 fitting components

c. Class "N": Nickel alloy Type 625 convoluted inner liner and corrosion resistant Type 321 or 347 fitting components.

d. Class "S": Corrosion resistant Type 321 convoluted inner liner and corrosion resistant Type 321 or 347 fitting components.

NOTE: Refer to Table 1 for specific fitting material definition.

Recommended Usage

a. Class "A" and "S" hose assemblies are recommended for continuous service use in static applications up to 800 °F maximum.

b. Class "B" and "N" hose assemblies are recommended for continuous service use in both static and dynamic flexure applications at continuous temperature up to 800 °F with excursions to 1200 °F within the pressure limits as defined in Figure 2.

intended Use:

The hose assemblies covered by this document are intended for use in aeronautical applications to convey air and gases in pneumatic systems, bleed air systems, heating and ventilating systems, and... View More
