    Hi all,

    I do not understand the difference between miter bends and elbows. I know
    miter bends are building with small welding pieces but Can anybody explain
    me ... Where Can I use them ?

    Thank U,

    Fernando Avila

    Thank you for this response!!

    Difference between a pipe elbow and a pipe bend is as follows:

    Pipe Bend is a generic term for any offset or change of direction in the piping. It is a vague term that also includes elbows.
    An elbow is an engineering term and they are classified as 90 deg or 45 deg, short or long radius.
    Pipe elbows have industrial standards and have limitations to size, bend radius and angle. The angles are usually 45 deg or 90 degrees. All others offsets are classified as pipe bends.
    Bends are generally made or fabricated as per the need of the piping; however elbows are pre fabricated and standard, and are available off the shelf.
    Bends are never sharp corners but elbows are. Pipe bending techniques have constraint as to how much material thinning can be allowed to safely contain the pressure of the fluid to be contained. As elbows are pre fabricated, cast or butt welded, they
    can be sharp like right angles and return elbows which are 180 degrees.
    Elbow is a standard fitting but bends are custom fabricated.
    In bends as the pipe is bent and there is no welding involved, there is less pipe friction and flow is smoother. In elbows, the welding can create some friction.
    All elbows are bends but all bends are not elbows.
    Bend has a larger radius then elbows.
    Generally the most basic difference is the radius of curvature. Elbows generally have radius of curvature between one to twice the diameter of the pipe. Bends have a radius of curvature more than twice the diameter.

    Probably no benefit to the OP, unless they are **really** patient. But
    relevant information is always relevant.

    I can find it interesting to read how someone else defines terms, so
    the post wasn't completely lost on me.

    Better than the spam that ends up being dumped in inactive newsgroups, for sure.

    Miter bends are not standard pipe fittings they are fabricated from pipes. Usually, they are preferred for size 10” & above because large size elbow is expensive. Use of miter bend is restricted to the low-pressure water line. Miter bend can be
    fabricated in 2, 3, & 5 pieces.
