WN orifice plates

Weld neck Orifice Flange Assemblies include integral pressure tappings as part of the mounting flanges. They are ideally suited to some steam flow applications where the whole assembly is butt welded directly into the line, the flanges being permanently fixed. The orifice plate may be removed for inspection or changed by loosening the nuts and bolts, while at the same time tightening the jacking screws to force the flanges apart.
