Thickness or Ga. of Stainless steel water tank?

Click For Summary
SUMMARY

The discussion focuses on calculating the thickness or gauge of 304 Stainless Steel for a 36-inch diameter vertical cylinder water tank, 25-30 feet tall, vented to the atmosphere. The absence of physical pressure from pumps or vacuum simplifies the design considerations. Factors such as water temperature (130°F) and air temperature (80°F) are acknowledged, but the elevation of 1000 feet above sea level is noted as less critical. The primary concern is the pressure changes due to water head, which are manageable in this scenario.

PREREQUISITES
  • Understanding of 304 Stainless Steel properties
  • Knowledge of pressure calculations in fluid mechanics
  • Familiarity with tank design standards
  • Basic principles of thermal expansion and its effects on materials
NEXT STEPS
  • Research ASME tank design codes for pressure vessels
  • Learn about the effects of temperature on material strength
  • Explore fluid statics and hydrostatic pressure calculations
  • Investigate thermal expansion calculations for metals
USEFUL FOR

Engineers, tank designers, and anyone involved in the construction or maintenance of water storage systems will benefit from this discussion.

How do you calculate the thickness or gauge of a given metal (304 Stainless Steel for example) for a 36" dia. round, vertical cylinder water holding tank? If filled say the tank would be 25-30 feet tall. No physical pressure (pumps or vacuum) on this vessel (vented to atmosphere). Flat bottom, not a bulkhead style base. Not sure if water temp matters but for the sake of measurements if needed. Let say an air temp of 80 deg. F. and a water temp of 130 deg. F. also not sure if it matters but elevation at roughly 1000ft. above sea level.

one possibility is to detremine the inner and outer dia s

and its for sure the pressure changes significantly wrt temperatures and head
for the described situation it may nt be of great concern
