Manifold pipe nipple for tubing attachement

We build dairy pipelines out of sanitary ss rigid tube where we need a nipple for silicone hose to connect to the ss line.

For example: My current project uses 3" OD x 16ga stainless "pipe". Every 44" I need to weld a 7/8" OD by 2" long nipple with the nipple's axis perpendicular to and intersecting the pipe's axis. A hole needs to be cut in the pipe with a diameter equal to the 3/4" ID of the nipple. The nipple is coped to the radius of the pipe and then welded over the hole. When it is installed a flexible silicone hose with a 3/4" ID and 1.33" OD is shoved onto the nipple 1.25". I want to use routing to create the pipe and the flexible hose.

What do I need in the model of the nipple to accomplish this. I have created other routing fittings but this one has me confused. It seems to me that this nipple has the characteristics of an olet to the pipe and a flange to the hose.
