How do I adjust the size of a flange?
The key sizes for a pipe flange are:
- the nominal size (i.e. the bore size of the flange, to match the bore size of the connecting pipe)
- the flange rating (which designates the pressure/temperature performance of the flange, i.e. 150#, 300#, 400#, up to 2500#)
How do I know what size flange to get?
Use a ruler or measuring tape to find the diameter of your nipple (the horizontal width across it) in millimeters (1 cm = 10mm). Measure the nipple alone, do not include the areola, which is the outer edge around your nipple. Add 4 mm to this measurement, so if your nipple is 20 mm across, your flange size is 24 mm.
Why raised face flange is used?
The Raised Face flange is the most common type used in process plant applications, and is easily to identify. The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint.
How do I know if my flange is too small?
If your breast pump flange is too small you may experience:
- Rubbing as the nipple is pulled against the sides of the breast pump tunnel.
- Pinching and squeezing of the nipple.
- Your nipple or areola becomes white or discolored.
- Low breast milk production.
- Painful milk extraction.
What is the most common flange size?
The average flange is between 24 and 27 millimeters (mm)—which corresponds to the size of your nipple—but not everyone who breastfeeds will fit these sizes. You can get smaller or larger flanges depending on the material: plastic flanges range from 21 mm to 36 mm and there is a 40 mm glass flange available.
