An assembly may include first and second components and a service flange. The first component has a first opening. The second component has a second opening in communication with the first opening. The service flange may be mounted to the first component such that the first component is disposed between the service flange and the second component. The service flange extends around the periphery of the first opening and may include a plurality of separate and discrete segments that are individually secured to the first component. Adjacent segments define joints that movably connect the segments together while allowing for relative movement between the segments before the first component is secured to the second component. The segments include mounting apertures spaced apart from the joints and receiving fasteners configured to fixedly secure the first component to the second component. Each fastener only engages a single segment of the service flange.
