    Comparing the Torque values to tighten vs loosen a bolt

    Agree. Have tested this now. Tested with torque of 50, 70 and 90 Nm. The needed torque to unscrew the bolt is always 10 - 20 % higher in my setup. (M26x1,5 brass/brass, no grease)

    Comparing the Torque values to tighten vs loosen a bolt

    If I torque a thread combination of M26x1,5; in brass material, with 90 Nm. Length of threds are 12 mm. Will the torque to unscrew the parts be equal, higher or lower? Why?

    Does the Ratio of Propane to Butane Change in a Half-Empty LPG Cylinder?

    So, the gasses keep their own properties and will not be a combination of the two?

    Does the Ratio of Propane to Butane Change in a Half-Empty LPG Cylinder?

    The outtake of gas will be in gas-phase (Vapor)

    Does the Ratio of Propane to Butane Change in a Half-Empty LPG Cylinder?

    If I have a LPG-cylinder that contains a mix of 50 % Propane and 50 % Butane, and I use half of the content. Will the mix still be 50/50 between Propane/Butane? Or will one of the gasses be used faster than the other?

    Can Nitrogen Replace CO2 for First Ignition in LPG Systems?

    No pressure. Air or CO2 is only the volume trapped inside the cylinder when mounting the valve.

    Can Nitrogen Replace CO2 for First Ignition in LPG Systems?

    You are right. It is some remains of air or Co2 inside the cylinders the first time. If you purge the cylinder i doesn't matter if it is air or CO2 inside. If you purge only lpg remains and ignition is easy. Co2 is a way to avoid to purge and still be able to ignite easy.

    Can Nitrogen Replace CO2 for First Ignition in LPG Systems?

    Yes. LPG is building pressure as normal, but somehow the air/oxygen comes out first. (Only some seconds). I think its related to the weight of oxygene.(lighter than lpg)?

    Can Nitrogen Replace CO2 for First Ignition in LPG Systems?

    It seems like if it is Oxygene inside the cylinder that oxygene come out before the LPG. If you replace oxygene with Co2 it seems like eighter; CO2 mix with LPG or are more heavy than LPG.

    Can Nitrogen Replace CO2 for First Ignition in LPG Systems?

    The kind of cylinders I talk about is this: http://www.ppsolutions.com.tw/plasticnotes/lpg-cylinders-technical-specification Manufacturer deliever the cylinder with atmosfære of CO2 insteed of air. This make the lpg Easy to ignite the forst time after filled with lpg. If air inside the air...

    Can Nitrogen Replace CO2 for First Ignition in LPG Systems?

    Hi In a new LPG-cylinder it helps 1. time lighting of gas if the cylinder is charged with CO2 instead of air prefilling of LPG. Will Nitrogen have same effect?
