weight per foot on stainless steel pipe? 2

[Witasz]

I'm trying to estimate the weight of a heating coil. The drawings and standards I have don't say anying about the weight of the coil. Here's what I do have: 4 1/2 inch OD, SCH 40 AW stainless steel type 304. Can anyone tell me what the approximate weight per foot might be? Thanks

About 11.2 lbs/linear foot of pipe

I checked ASME B36.19 for NPS 4. The OD is 4.5-inch. SCH 40S reflects 10.8 pound per foot (16.08 kg/m) based upon carbon steel. Note e on the table indicates that the different grades of stainless steel vary in weight. Ferritic stainless may be about 5% less, austenitic stainless about 2% greater than the values.
