ABSTRACT:
A riser clamp mateable with a riser, wherein the riser clamp supports a column of the riser as material passes therein, and the riser clamp further covers or seals the opening in the partition formed through which the riser passes. The riser clamp comprises a pair of clamp members adjoined to a riser. The clamp members comprise a semi-annular jacket seated against the riser, a collar circumscribing the jacket, wherein the collar covers an opening formed in a partition through which the riser passes. The clamp members further have a pair of mounting flanges depending from the jacket and the collar, with the mounting flanges extending laterally in opposing directions from the jacket and coplanar to a medial margin. Each one of the mounting flanges accommodates a fastener for adjoining the pair of clamp members securely about the riser.
