The present invention relates to a cleanable sight glass for installation on welded pads. In one embodiment of the invention, an adapter plate is provided to allow existing welded pad sight glasses to be retrofitted, allowing cleaning without disassembling the glass each time a cleaning is needed. The adapter plate mates between the original welded pad for the sight glass and the original top plate that was installed over the sight glass. The adapter plate contains ports on each end for the installation of plugs. The plugs can be removed and a brush can be used to clean the glass without disassembly of the welded pad sight glass. In an alternative embodiment, the ports for the plugs can be installed into the ends of the welded pad itself upon original manufacture of the particular piece of equipment so that an adapter plate is not needed. The welded pad should be made of thickness great enough to accommodate said ports. |
