Pipe fabricated with ends milled for horizontal deviation

[Freddy73]

Can anybody help me?

How can I to verify if a installed piping system it is safe, when for a change horizontal direction in a section, was made joining both ends pipes milled for obtaining a deviation of 11 horizontal degree without the use of any fitting. The dates of pipe are:
24”Ø, 0.875” wall thickness, Design pressure: 739 psi, Operation temperature: 174 degree F;
And if the installation is no safe, what must I do?

Hi Freddy73,

various piping codes have rules for calculating mitered bends such as yours, e.g. ASME B31.3.

Try checking the code for your piping for the formula to calculate the mitered bend. If the calculation proves the bend to be unsafe, you should instead use a preformed bend of 11 deg.
