摘要： A clamp connection for use with flowlines of a hydraulic fracturing operation has a female clamp hub having a seal pocket formed in the face thereof, a male clamp hub having a raised face at an end thereof, an elastomeric seal received in the seal pocket of the female clamp hub, and a clamp connector extending around the female clamp hub and the male clamp hub so as to maintain the male clamp hub and the female clamp hub in a liquid-tight relationship. The male clamp hub has an annular protrusion extending outwardly of the raised face. The annular protrusion bears against a side of the elastomeric seal. The raised face of the male clamp hub is received in an interior of the female clamp hub.
