Cylinder gland

Cylinder gland

Cylinder gland

(OP)
Hi there,

I am designing a cylinder with a bolted gland. (WP 250 bar)
Can anyone tell me if there are standardized calculations for the bolted Gland. I am currently working with Roark load case table 24 load case 1F. But I am nut sure if I can see the bolts as a fixed connection.

Thanks

Thomas

RE: Cylinder gland

You can use the tensile stress area and material yield strength of a fastener to determine how much pull it can with stand and your safety factor to determine fastener diameter and quantity. The more fasteners the thinner the flange, and more compact it can be to a point. 6 to 12 bolts depending on bore usually works well. Once you have your design do a static pressure test to make sure it makes the safety factor without failure.
