XD Flanged Y-Branch

XD Flanged Y-Branches 14ga, also known as wyes or laterals are added typically to accommodate an additional line or lines into the main one in applications that require thick walled ducting. They are manufactured in 14ga galvanized steel with flanged ends and standard 60° with a 90° option.

XD Flanged Y-Branches, also known as wyes or laterals are added typically to accommodate an additional line or lines into the main one for use in highly abrasive applications that require thick walled ducting. They are higher wear and an excellent alternative where standard gauged y-branches are requiring frequent replacement.

XD Flanged Y-Branches are manufactured as follows:

  • In 14 or 12 gauge Galvanized steel with diameter sizes of 8 to 40 inches and standard 60 degrees with an optional 90 degrees.
  • Seam is solid welded and leak free.
  • Flanged ends come standard with Angle Flanges (ANGFL), retained with a 5/8 inch vanstone lip. They are attached loosely in order that the flanges can be rotated for bolt alignment. Flange can be fully welded upon request.

NOTES:
  1. At temperatures ranging between 390° F and 480° F, the zinc-iron alloy layers in the galvanized steel will continue to provide a high level of protection from corrosion. However, there may be some peeling, changes in mechanical properties, and reduction in the corrosion protection. Recommended maximum service temperature is 390° F.
