Everyone, take a look – what is this in the design drawings?
Reducer (commonly known as size change), 250 to 150
Diameter reduction from 250 to 150
It’s about the change in diameter; in reducer pipes, the larger diameter is at the front and the smaller diameter is at the back.
The diagram shows it as non-standard; the correct answer is already provided on the 2nd floor. For a reduction from DN200 to DN150, the reducer is indicated as “200X150” or “DN200/150”.
This is a reducer, also known as a size change fitting.
