The invention relates to a clamping and sealing clamp, in particular to a clamping and sealing clamp for the end of a pipe in order to solve the problems that due to the fact that clamping and sealing are mutually independent in an existing pipe tensioning-expanding test experiment and are mutually affected when in use, smooth conduction of the experiment is difficult to guarantee, clamping and sealing of the pipe can not be effectively combined, and the accuracy of the pipe performance experiment is affected. The clamping and sealing clamp comprises a mandrel, a sealing ring, a wedge-shaped block, a carrier plate, a screwing part, an elastic element, an outer clamping ring, N wedge-shaped inner claws, N wedge-shaped outer claws and N ejection rods. The screwing part is in threaded connection with the other end of the mandrel. The mandrel is sleeved with the outer clamping ring. The wedge-shaped block, the N wedge-shaped inner claws and the N wedge-shaped outer claws are arranged between the outer clamping ring and the mandrel. The N wedge-shaped inner claws and the N wedge-shaped outer claws are arranged in the peripheral direction of the mandrel. The part, between the screwing part and the outer clamping ring, of the mandrel is sleeved with the carrier plate and the elastic element. The elastic element abuts against the carrier plate and the outer clamping ring. The clamping and sealing clamp is used for clamping and sealing the end of the pipe during a pipe tensioning-expanding test experiment.
