Stainless Steel Tube Fitting Specifications

Industrial Tube Manufacturing stocks a range of butt weld fittings to complement our Stainless Hygienic Tube sizing, suitable for process lines in dairy factories, breweries, distilleries and other sanitary and food processing applications. We partner with suppliers who understand process engineering, ensuring we deliver high-quality sanitary tube fittings that provide a consistent and straightforward fit-up with our tube.

Specification: Fittings are manufactured to the AS 1528.3 standard. This Standard specifies dimensional, material and hygienic requirements for butt weld tubular fittings including bends, tees, reducers, y-sections and crosses, for incorporation in tube lines for food processing and hygienic applications. All bends are manufactured in New Zealand to Universal Standard (UNI) dimensions.

Surface Finish: For all fittings, the external surface is polished to a 320G finish. The internal surface (excluding weld zone) is under 0.8μm Ra as per the standard. The weld area is under the maximum Rt value of 14.0μm.
