The following variables should be considered when ordering tubing for use with FITOK tube fittings: Surface finish Material Hardness Wall thickness Surface Finish Surface finish is very important to proper sealing. Tubing with any kind of depression, scratch, raised portion, or other surface defect will be difficult to seal, particularly in gas service. Material Metal tubing material should be softer than fitting material. For example, stainless steel tubing should not be used with brass fittings. When tubing and fittings are made of the same material, tubing must be fully annealed. Hardness FITOK tube fittings are designed to work properly with the tubing that is suggested in the ordering instructions. FITOK stainless steel tube fittings have been repeatedly tested successfully with tubing with hardness up to 00 HV and 90 HRB. Wall Thickness The accompanying tables show working pressure ratings of tubing in a wide range of wall thicknesses. Except as noted, allowable pressure ratings are calculated from S values as specified by ASME B., Process Piping. FITOK tube fittings have been repeatedly tested in both the minimum and maximum wall thicknesses shown. FITOK tube fittings are not recommended for tube wall thicknesses outside the ranges shown in the accompanying tables for each size. Tubing Handling It is important to properly handle the tubing in order to reduce the scratches and protect the surface finish. Tubing should never be dragged out of a tubing rack or across a rough surface. cutters or hacksaws should be sharp. Do not take deep cuts with each turn of the cutter or stroke of the saw. The tubing will go all the way through the ferrules without damaging the ferrule sealing edge. Part Number Description Pipes Stainless Steel Seamless Pipe 4

3 Tubing and Pipes Tubing and Pipes Gas Service Suggested Allowable Working Pressure for Stainless Steel Tubing Gases ( air, hydrogen, helium, nitrogen, etc.) have very small molecules that can escape through even the most minute leak path. Some surface defects on the tubing can provide such a leak path. As tube outside diameter () increases, so does the likelihood of a scratch or other surface defect interfering with proper sealing. The most successful connection for gas service will occur if all installation instructions are carefully followed and the heavier wall thicknesses of tubing on the accompanying tables are selected. Tubing Installation Table Fractional Stainless Steel Seamless Tubing Allowable working pressures are calculated from an S value of psi (7. MPa) for ASTM A9 tubing at -0 to 0 F (- to 7 C), as listed in ASME B., except as noted. Multiply stainless steel rating by 94 for working pressure in accordance with ASME B.. For Welded Tubing For welded and drawn tubing, a derating factor must be applied for weld integrity: For double-welded tubing, multiply working pressure by.
