Double welded slip-on flanges should be ____ between the welds for fluid services that require leak testing of the inner fillet weld , or when fluid handled can diffuse into the enclosed space, resulting in possible failure

Answer 1

Double welded slip-on flanges should be purged between the welds for fluid services that require leak testing of the inner fillet weld or when the fluid handled can diffuse into the enclosed space, resulting in possible failure.

Step-by-step explanation:

In fluid services that require leak testing of the inner fillet weld or when the fluid handled can diffuse into the enclosed space, double welded slip-on flanges should be purged between the welds.

Purging involves removing or displacing the fluid in the enclosed space with another medium, such as an inert gas, to prevent contamination or failure of the welds.

This process ensures that the inner fillet weld is properly inspected and tested, as well as prevents any potential diffusion of the fluid into the enclosed space.
