    Difference between nm3/h and sm3/h??????

    Fisher regulators has a nice little conversion calculator. 1 cfh = 0.02832 Sm3/h = 0.0268 Nm3/h, according to this calculator.

    Water Dew Point in Natural Gas

    Thanks - Is that data for the gas at 3,600 psi, or atmospheric? I was looking for both. Also, what book can that curve be found in or can it be purchased separately? I may need to purchase it, as we will be sampling this gas stream regularly for fuel quality maintenance (Compressed nat gas...

    Water Dew Point in Natural Gas

    I wonder if anyone can point me in the right direction on this question. I have 7 lbs/mmcf water vapor in natural gas at atmospheric pressure. What is the water dew point temperature? At 3,600 psi? Where do I find the curve or method to calculate this? Any help would be greatly...

    Natural Gas Piping

    Hi All: Sorry I'm late to the party. In the Gas Industry (Natural Gas, that is) we have used a nice little program called GasCalc, by Bradley B. Bean. Call him at 800-391-9391. The program has all kinds of features that help you design natural gas systems, including pipe flow, line pack...

    Pipeline design pressure for ASME B31.8 pipe

    If you are designing a natural gas pipeline you must comply with CFR 49 Part 192, "Transportation of Natural and Other Gas By Pipeline: Minimum Federal Safety Standards". I mention this because you must be careful that the pipe you choose meets the requirements of this standard, which...

    140 Deg. Domestic & Hot water heating system?

    Wait a minute. Are you all talking about hydronic heating? There are several systems (Apollo brand comes to mind) that have been out for many years that use a domestic hot water heater to supply both hot water for domestic use and for heating. This is very common installation, and can be...

    Pressure Testing of Fuel Pipe

    You may find the National Fuel Gas Code to be helpful. Look in Part 4, Inspection, Testing, and Purging. You should be able very quilckly to adapt the code requirements to your needs. For instance it gives you the duration requirements based on volume of fuel line, the test medium...

    Minimum radius of sag bends in a pipeline

    Thanks, JeffH - I found the Rules of Thumb Handbook, and sure enough there was exactly what I was looking for! I feel good that my method was basically on target - I was within 2' of their answer. Nothing like reinventing the wheel! By the way, the ROT Handbook doesn't take into account the...

    Minimum radius of sag bends in a pipeline

    I am trying to determine the amount of deflection allowable in a buried pipeline, using the trench to flex the pipe, without exceeding the maximum allowable stress on the pipe. I am taking into account internal pressure. The temperature is not a factor, as the fluid is at ambient ground...
