SCP-015

 - Pipe Nightmare is a Series I SCP written by DrGears. The object of interest covered by the article is classified as Euclid. 015 was among the first post-"Edit This" articles posted to the Wikidot main wiki following the move. SCP-015 concerns a complex of water and steam transport mechanisms. As such, it falls into the early SCPs tendency to focus on horror.

Summary
"SCP-015 is a mass of pipes, vents, boilers and other various plumbing apparatus completely filling a warehouse in ███████. The pipes appear to grow when not under observation, attempting to connect to nearby structures via sewer systems and underground plumbing. " DrGears, SCP-015.

As alluded to in the above quote from the original site, SCP-015 is a continously growing series of water and steam transport mechanisms that advances when no-one is directly observing them.

The object reacts in a defensive manner to incursions/attempts to damage or alter pieces of itself and incorporates/utilizes a vast array of materials to continue expanding.

Interpretation
Like the vast majority of early Series I articles, SCP-015 focuses on some aspect of urban/psychological horror through description and relative implications. The horror in this article primarily originates from it's relentless, unending expansion and infiltration into surrounding urban structures. This invokes imagery similar to invasion of vines or Kudzu into spaces they shouldn't be with the added penchant of being capable of defending itself from damage and alteration.

The article also invokes a classic example of "The Rules Don't Apply Except When They Do" with the defensive reactions resulting in pipes carrying such a wide variety of hostile substances and organisms. The article simultaneously establishes that there are some sort of rules based on the responses and length of time of spray, it's just not understood what the exact rules are or how it produces these items, invoking a fear of what we don't know.

The final thing the article does is leave the reader with fridge horror in implying that people who enter the pipe maze may get trapped inside, or even sucked into the pipes themselves where they become helplessly trapped.

Behind the Scenes
Pipe Nightmare was published in 2008 shortly following the move from Edit This to Wikidot. The article was notably untouched during the Mass Edit of 2012 which helped cull a lot of low quality material from the wiki.
