Selecting the right duct material is critical for chemical and wastewater applications where corrosive fumes, moisture, and harsh operating conditions can shorten system life. This guide compares galvanized steel, stainless steel, and flanged ductwork, helping engineers, contractors, and plant managers choose the best solution for long-term performance, reliability, and corrosion resistance.
Y-Branches
Y-Branches are exactly that—Ys with the two inlets diverging from the centerline. Once again, the volume of the outlet is the sum of the two inlets.
Typically the two inlets are the same size. If one needs to be smaller than the other, the branch is made with the two inlets equal to the largest requirement, and then a reducer is used to reduce to the smaller requirement.
All branches are 18 gauge or heavier.
