ABSTRACT:
An improved band seal clamp for clamping of tubular members is disclosed which features a band-like clamping member having slots formed in its ends for interaction with bolts held rigidly in holes formed in a spacing member disposed between the ends of the clamp. The ends of the band are shaped to define surfaces at an angle with respect to the surface of the tubular members which coact with force bars having corresponding shapes. Throughbolts fit through the slots in the band, holes in the force bars and the holes in the spacing member, so that upon tightening of the bolts the ends of the band clamp are forced outward, thus exerting a compressive stress on the tubular member.
