По поводу "paddings" - см. ниже (reinforcing pad), кажется это оно и есть - "упрочняющая накладка" или "башмак жесткости"

WEEP-HOLE
On a number of images, you might be have seen a round hole in the reinforcing pad. This is a "Weep Hole" and may have multiple functions. Sometimes also called Tell Tale hole or Vent hole.

Opinions about the use of this hole varies, and therefore I give 2 possible uses of a weep hole.

By threading the hole, a test gauge can be thread for a "air/soap" test to check for leakage.
The thread, mostly 1/4" NPT will be used.
NPT
The American National Pipe Thread Tapered (NPT), is the best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound.

ASME B1.20.1 covers dimensions and gaging of NPT pipe threads for general purpose applications.
Weep holes serves as a vent during welding for entrapped gasses and prevents the reinforcing pad from becoming a "jacketed" vessel.
Weep holes in reinforcing pads shall be sealed upon completion of pressure test.

weep holes for paddings and attachments = дренажные отверстия в упрочняющих накладках и навесном оборудовании
