A compact solid-cover access opening

This round handhole uses a solid cover with a separate lifting handle. Upper and lower hinge parts are identified in the assembly drawing, while handwheels are arranged around the opening. Its compact size schedule helps distinguish the handhole from the larger round manways in the same catalogue.

Handwheels, swing bolts and seal

The drawing lists handwheels and swing bolts as the closure components and identifies a silicone perimeter gasket. The frame and cover have 304 or 316L options; hinge and handle components are separately listed as 304. Select replacement closure parts and seals against this assembly rather than only the nominal opening size.

Seven sizes with separate outside diameters

The seven size entries are 80, 100, 125, 150, 200, 219 and 250 mm. Outside diameter OD is recorded in a separate column, alongside H, t and t1. Check the selected row before preparing the welded connection; the size name and collar outside diameter are not interchangeable dimensions.

Layout and routine inspection

Allow access to the perimeter closures and space for the cover and handle when planning adjacent fittings. The welded collar and cover need to be considered together in the installation layout. Routine inspection can focus on the gasket seat and visible fasteners, with replacement components matched to the chosen drawing size.
