Cylindrical Vacuum Chamber Wall Thickness

Asme viii only considers membrane stresses circumferential in a spherical vessel i e.

Cylindrical vacuum chamber wall thickness.

Radial stresses are ignored which is considered reasonable given that the maximum. Chamber diameter wall thickness under 17 inches. Chamber feet on the outside ensure stability eye bolts or hoisting shackles allow safe transport. A main flange with fitting lid allows access to the chamber a door hinge increases ease of use.

Producing a vacuum chamber means de fining the boundary conditions inner and outer envelopes operational constraints etc choosing the material designing the parts manufacturing and assembling these parts together and putting them under vacuum. This paper gives the methodology methods and hints for designing vacuum chambers. Thicker walled material should be specified for chambers with ports having angular tolerances of less than 1 2º or for processes that require large mass for vibration dampening. Chamber diameter of 600 mm requires a flat bottom about three times the wall thickness as of a dished end.

Pressure vessels calculates the wall thickness of plain spheres of same material and equal wall thickness throughout. The material for both systems is black iron sheet. Any bulk container will naturally try to form a spherical shape under sufficient internal pressure. The pressure and the temperature i want to work at are in the range of 0 1 0 07 mbar and 200 350 degree of centigrade.
