TECHNICAL QUESTION: What's the difference among a conduit", a "sleeve" and a "stub-up" in the construction field?

Hi guys,

Hope U can help me:

I'm doing some translation from English to Spanish about materials for construction. Thus, I'd like to know what the difference is among a sleeve, a stub-up and a conduit. The information on the web makes me think they are the same but I'd like more information from people with technical bakground.

Thanks in advance

Never worked construction, but I picture a stub up as conduit which is installed prior to the pouring of concrete, sticking up high enough so the concrete cannot flow inside. When the walls are later erected, the conduit runs may be continued to their ultimate destinations, and the wires pulled. In most jurisdictions, all commercial structures would have their wiring pulled through conduit, often called EMT, for electrical metalic tubing, or thinwall.

  • The stuff is too thin to be threaded, so the joints are slip-fit, with set screws or compression fittings.
  • The heavy wall stuff has the same nominal sizes as water pipe, and is usually galvanized and threaded, the major difference being that the threaded joints are not tapered, making them easier to install.
