Technical Details

-5% Standard Tolerances • Hole sizes: - .015" to .025" over the listed dimensions unless specifically mentioned • Product inside diameter (ID) and outside diameter (OD): - Produced within commercial, dimensional tolerances. • Bend tolerances and angle of bend: - +/- 2° • Cutting tolerances on pipe and tube: - +/- 1/16" • Multiple Bend Tolerances: - +/- 2° and +/- 1/8" center-to-center through 2.50" OD - +/- 1/4" center-to-center above 2.50" OD Deformity Issues with Bent Tubing The process of bending pipe and tube results in deformation which is unavoidable. In round sections, this causes some ovality in the bent sections of material that may result in a mismatch between the elbow and stock, straight material. The deformation may be as much as +5% in the vertical dimension and -5% in the horizontal dimension. In square and rectangular tube sections, the tube will tend towards a trapezoidal deformation. ASTM B31.1 allows for a maximum deformity of 10%on most formed parts that operate below 500 psi and 8% above 500 psi. Wagner strives for a deformation of -5% on the inside of the bend and +5% on the outside of the bend. This may be avoided by ordering elbows with tangents since the tangent sections will be unaffected by the bending process. Verify Outside Diameter for Flanges Wagner flanges are sized +.015" to .025" above outside diameter as noted on pages 52-61. Confirm the dimensions on your pipe or tube as tolerances may vary. Please note that galvanizing, painting or powder coating will increase the diameter of your material and may Porosity is a normal attribute of cast products. Every effort is made to minimize the appearance of porosity but minor pitting can not be avoided and is to be expected. Aluminum and Paint Reaction with Cement When aluminum components come into contact with cement or lime mortar, exposed aluminum surfaces should be painted with heavy bodied bituminous paint, water-white methacrylate lacquer or zinc chromate. Dissimilar Metals Metals are rated according to their nobility. When dissimilar metals are in contact with each other in the presence of oxygen and moisture, the more noble metal will corrode the less noble. Contact between dissimilar metals should always be avoided. If contact cannot be avoided, the adjacent surfaces should be painted with bituminous paint or zinc chromate primers or paints. Taping or gasketing with non-absorptive materials is also effective. result in a mismatch. Casting Porosity +5% +5% -5% inside of bend Before Bending After Bending Before Bending After Bending

Care should be taken to prevent the wash from copper alloy surfaces onto adjacent, exposed, less noble metal surfaces since the traces of copper salts carried in the wash can accelerate the corrosion of less noble metals. Pressure Treated Lumber Pressure treated lumber—ACQ lumber—is treated with copper sulfate which will corrode steel and aluminum. Use only stainless steel or heavily galvanized steel components with ACQ lumber products. Specifying Parts for OD Tube or Pipe Size IPS stands for iron pipe size—a standard that was originally developed for fluid transfer but has also become the standard for designating handrail sections in all alloys. There is often confusion as to which size product the customer actually needs—pipe size or OD tubing size. Keep in mind that pipe size refers to a nominal—not actual —inside pipe diameter. Schedule refers to the pipe’s wall thickness. The dimensions provided for OD tubing on the other hand refer to the actual outside diameter and wall thickness. Example: 1 1/2” pipe size flanges have an opening to fit over 1.90” OD—the actual outside diameter of 1 1/2” pipe—while 1.50” OD tubing has a true 1.50” outside diameter and the flange is sized accordingly. Actual Dimensions for Nominal Pipe Size Use the following formula to determine the ID for any given pipe size: ID = OD - (2 × t) Where: OD = Outside Diameter ID = Inside Diameter; and t = wall thickness 1.900" 1.500"

Stainless Steel Stainless steels contain at least 12% chromium and form a thin, invisible, protective, corrosion-resistant, passive film on their surface. This film forms spontaneously when the chromium reacts with oxygen in air and water. If the film is damaged or removed during fabrication or polishing, it self-repairs immediately—so long as the surface is clean. If stainless steel corrodes, typically highly localized metal loss or pitting occurs—rarely general or uniform corrosion of the entire surface.
