What Are Pipe Wyes

Pipe Wyes

Pipe wyes are similar to tees, except for the angling of the branch line to reduce friction and turbulence. They are commonly used to attach a vertical drainpipe to a horizontal one. The connection is typically at a 45-degree, rather than 90 degrees; if a branch turns out further at the end to 90 degrees (perpendicular), the fitting becomes a combo tee. Pipe wyes and combo wyes follow a long-sweep pattern relative to sanitary tees and other short-sweep bends, which have a smaller radius and require less space. A wye may also be used to split a branch line equally in two directions, such as the splitting of a main line into two smaller branches.
Pipe wyes also have industrial applications. Although low-priced wyes are often spot-welded, industrial-strength wyes are flash-welded at each seam. In long-distance pipeline applications, a wye is used for pigging to maintain flow.

Materials used:
There are various materials used in the making of wyes. They are as follows:
  • Carbon steel
  • Stainless steel
  • Iron
  • Copper
  • Monel
  • Nickel
  • Titanium
  • Zirconium
  • Plastic
  • Rubber etc.

Buying Tips

Certain factors that are to be considered for the purchase of pipe wyes are as follows:

  • Pipe and Tube Sizes
  • Wall Thickness
  • Materials
  • Degree of Branch: 30, 45, and 60
  • Finishing
  • Durability
  • Corrosion resistant

Various shapes of pipe wyes:
The pipe wyes (in the form of Y) can take various shapes. Below we give a diagrammatic representation of some pipe wyes.
Pipe Wyes - What Are Pipe Wyes
As seen in the above figures, the first one is a standard pipe wye, exactly in the shape of the alphabet “Y” in a horizontal position. The second is a pipe wye in a vertical position with three branches. The third one is a special type of pipe wye in the shape of a standard tee with a 45° bend and particularly recommended to be used in large-diameter piping.
