Cylindrical Vacuum Chamber Wall Thickness

Pressure vessels calculates the wall thickness of plain spheres of same material and equal wall thickness throughout.

Cylindrical vacuum chamber wall thickness.

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. Vacuum chamber design guide chamber wall thickness recommended minimum wall thicknesses are listed in the table below. Chamber diameter wall thickness under 17 inches.

The material for both systems is black iron sheet. This paper gives the methodology methods and hints for designing vacuum chambers. Chamber feet on the outside ensure stability eye bolts or hoisting shackles allow safe transport. The d shape chamber when viewed from above combines the thin wall of the cylindrical chamber with the volume and large o ring sealed access door of the box chamber making it appropriate for high vacuum applications.

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. Radial stresses are ignored which is considered reasonable given that the maximum. 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. The door is frequently aluminum to reduce weight.
