What should the minimum clearance be from the bottom of a pipe handrail to the top of the horizontal portion of the wall bracket?
 
Depends where you are using the handrail.

Is it for stairs in a commercial setting? Residential?
 
From your name, I am assuming that you are making custom metal handrails in an off-site facility?

Welcome to the forum,

The distance will depend on the diameter of the pipe, as the starting point for a perimeter of 4" is 1.5", both from the wall and the vertical clearance beneath the handrail profile.

However, for each 1/2" of additional perimeter over 4" you are allowed to reduce the height by 1/8", as thus with your note of using pipe, I would venture a guess you are using 1.25" pipe or 1.5" pipe.

In the 2015 & 2018 Model IBC Section 1014.4 Continuity, exception 3 spells this out, Not sure which applies to your project in MN

However,

The 1.25" schd40 pipe is 1.66" in diameter and aprx 5.2" in circumference and as thus is allowed a 0.25" reduction, so 1.25" beneath, however still 1.5" from wall or guard.

The 1.5" schd40 pipe is 1.9" in diameter and aprx 5.9" in circumference and as thus allowed a 0.375" reduction, so 1.125" beneath, again however still 1.5" from wall or guard.

The same reductions are allowed in ANSI A117.1 & ADA/ABA under section 505.6 Gripping Surface exception #2.
as posted by Yikes in Post #5 above.

This is all based on the model codes, and I am not sure what adoptions and modifications MN has made, but I would be surprised if they would change this portion of the code since it aligns with ADA/ABA.

As a side note, as a metal fabricator, I would suggest looking at https://NOMMA.ORG
