Cylindrical Vacuum Chamber Wall Thickness

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.

Cylindrical vacuum chamber wall thickness.

The material for both systems is black iron sheet. The door is frequently aluminum to reduce weight. A main flange with fitting lid allows access to the chamber a door hinge increases ease of use. Chamber diameter of 600 mm requires a flat bottom about three times the wall thickness as of a dished end.

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. Chamber feet on the outside ensure stability eye bolts or hoisting shackles allow safe transport. Any bulk container will naturally try to form a spherical shape under sufficient internal pressure. This paper gives the methodology methods and hints for designing vacuum chambers.

Vacuum chamber design guide chamber wall thickness recommended minimum wall thicknesses are listed in the table below. Asme viii only considers membrane stresses circumferential in a spherical vessel i e. Pressure vessels calculates the wall thickness of plain spheres of same material and equal wall thickness throughout. Radial stresses are ignored which is considered reasonable given that the maximum.
