Patent ID: 7625018

Claim:
A flange seal clamp housing for attachment to a cylindrical body, particularly to a pipe, said housing being a unitary metal casting comprising: a) an open annular base element provided with a first, ingoing flange at a first side of said base element and a second ingoing flange at a second side of said base element, said second ingoing flange having a cross-section forming a loop extending outwardly beyond said base element; b) a pair of clamp members projecting outwardly from said base element, said clamp members being positioned face to face and each having an aperture to allow the insertion of a tightening element therethrough, which can be operated to reduce the distance between the two ends of said open annular base element and thereby press an annular seal element against the outside of a pipe inserted inside said seal clamp housing, said housing after release of said tightening element returning to its original dimensions; and c) integral reinforcing ribs across walls of said flange clamp housing.
