2019-12-12 · The Shell Thickness calculation page is to calculate the wall thickness of a cylinder, cone and sphere under pressure without holes. The calculation does not take into account the extra stress around holes for nozzles and is therefore a basic strength calculation. Calculation codes are ASME, Dutch Rules and the EN Euronorm.
Operating experience, which has shown that the minimum allowable wall thickness in the stretched zone of the bend should exceed the computed wall thickness of the straight tube by 25%, should be considered in developing the computational method.
The average thickness of pipe tubing refers primarily to the actual wall thickness of the pipe. According to Supply Rite Steel Inc., this number is generally no less than 12.5 percent less than the nominal thickness of the pipe. To calculate the actual thickness of the pipe's wall, you can simply multiply the nominal thickness by 0.875.
2018-2-1 · design stress as the operating pressure of the unit is lower than the design pressure and the actual tube wall thickness is greater than the specified minimum wall. The amount of internal scale or deposit that may be tolerated by a particular tube before a high temperature metal problem occurs is a function of the unit pressure and tube location.
