Reducers

[anolan23]

Hello,

An opening is too large for our nozzle connection and I am thinking about using a reducer to reduce the opening size. So it would go from a small X-section at the run pipe to a larger X-section further away. Are these requirements described in UG-36?

Also, is the reducer considered a fitting? If so, would this need to fit under the conditions of UG-44 Flanges and Pipe Fittings?

THANKS

Hi Anolan,

If i m getting it right, your's equipment nozzle size is smaller than the line size. If Yes, then it is a normal practice to use reducer (or Expander) to match the nozzle with line. The vessel Design code limit is the equipment flange face.
