Bolt Torque and Tensioning ASME B31.8, ASME B16.5 3

[092074]

I am a new Mechanical Engineer presented with the above task by my Superior.

See Below pertinent Data:

Pipeline Parameters:

Pipeline Material: API 5L Gr60
Nominal Diameter 24 inch
Thickness: 0.688 inch
ASME/ANSI CLASS of the Pipeline is 600#
Process Fluid is Compressed Natural Gas 66 Barg Operating Pressure
Normal Operating Temperature is 20 degrees Celsius
Design Pressure is 94.8 Barg at 60 degrees Celsius
Hydrostatic Test to 155 Barg @ 37 degrees Celsius

Could you please recommend/help me with creating a spec for above parameters...I have never done this before and yes I am looking for any kind of guidance or examples for the above mentioned task.

Thanks

Dejan,

The gasket is an important consideration for the required bolting torque. The gasket manufacturer should have good data for bolt torques on B16.5 standard flanges.

Check websites of gasket manufacturers
