An anti-telescoping device (ATD) is provided for installing a spiral wound filtration element in a tubular pressure vessel, the ATD being a generally wagon wheel-shaped disc having an outer peripheral rim, a central hub, a plurality of annularly spaced ribs connecting the peripheral rim with the central hub, and engagement catches located at transitions of the ribs with the peripheral rim for receiving projections from a handle. The handle for holding, installing and/or extracting a spiral wound filtration element with ATD has a plurality of annularly spaced legs extending radially outward and axially from a central holding portion, the legs having engagement feet at distal ends of the legs and being adapted to lock into the engagement catches in the ATD on at least one end of the filtration element. The ATD has other novel features which facilitate the insertion of the filtration element into, the operation in, and the removal from the tubular vessel. |
