For example, ASTM A450, a general tubing specification, reads:  \n11. Straightness and Finish  \n11.1 Finished tubes shall be reasonably straight and have smooth ends free of burrs. They shall have a workmanlike finish. Surface imperfections (Note) may be removed by  \nTUBING DATA  \ngrinding, provided that a smooth curved surface is maintained, and the wall thickness is not decreased to less than that permitted by this or the product specification. The outside diameter at the point of grinding may be reduced by the amount so removed.  \nNote: An imperfection is any discontinuity or irregularity found in the tube.  \nTubing Material  \nOur suggested ordering instructions for each type of tubing are shown under the respective tables.  \nTubing Outside Diameter Hardness  \nThe key to selecting proper tubing for use with metal Swagelok tube fittings is that the tubing must be softer than the fitting material. Swagelok tube fittings are designed to work properly with the tubing that is suggested in the ordering instructions.  \nSwagelok stainless steel tube fittings have been repeatedly tested successfully with tubing with hardness up to 200 HVand 90 HRB.  \nTubing Wall Thickness  \nThe 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 B31.3, Process Piping.  \nSwagelok tube fittings have been repeatedly tested in both the minimum and maximum wall thicknesses shown. Swagelok tube fittings are not recommended for tube wall thicknesses outside the ranges shown in the accompanying tables for each size.  \nTubing Handling  \nGood handling practices can greatly reduce scratches on tubing and protect the good surface finish that reliable tube manufacturers supply.  \n■ Tubing should never be dragged out of a tubing rack or across a rough surface.  \n■ Tube cutters or hacksaws should be sharp. Do not take deep cuts with each turn of the cutter or stroke of the saw.  \n■ Tube ends should be deburred. This helps to ensure that the tubing will go all the way through the ferrules without damaging the ferrule sealing edge.  \nTubing Data 225  \nGas Service  \nGases (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.
