Consult SM oiler Vessel Code, SM 3., 3.3, or other applicable codes for information on weld setup, technique, and additional considerations for welded systems. The choice of fitting, pipe, and tubing material being welded is critical. Using the same materials will ensure the same coefficients of epansion and will reduce the possibility of poor welds, out-of-roundness, or dimensional changes that are detrimental to a good weld. Pipe threads are based upon the requirements of NSI.20. (NPT) and MI-P-705 (NPT) for tapered pipe threads.

To convert room temperature pressures to 3. code rules, multiply the published room temperature rating by To determine elevated temperature pressure ratings to 3. code rules, multiply the published room temperature ratings by 0.94 and then by the elevated temperature factor.

3 Weld ittings 3 Micro-it Weld ittings Compact design accommodates tubing systems requiring miniaturization allows close component spacing provides flow and service ratings equal to larger weld fittings. Rounded body block helps prevent damage to other components during system fabrication or maintenance. Ultrahigh-purity cleaning with 5 µin. (0.3 µm) Ra surface finish is available. Standard surface finish is 0 µin. ( µm) Ra. Material heat code is roll stamped to ensure raw material traceability. aser etch marking identifies manufacturer, material, and, when applicable, ultrahighpurity cleaning. Square, sharp, burr-free tube weld ends enhance alignment, maintain tube wall uniformity, and promote weld repeatability. Radius junction allows for a smooth flow transition and eliminates pockets and entrapment zones.
