Apparatus For Hydrostatic Testing

An apparatus for sealing a flanged opening, which apparatus is comprised of:

• a) a rear plate section having a slot for receiving a flange of a flanged opening to be sealed;
• b) a front circular plate section having a through-hole at its' center for receiving a shaft capable of longitudinal movement;
• c) an elongated shaft extending through said through-hole, said shaft having a first end and a second end which first end extends through said through-hole;
• d) a blind flange having a first face and a second face which second face is secured at its center to said first end of said shaft;
• e) a middle section having a slot for receiving the flange of said flanged opening to be sealed, which middle section is located between and connected to said rear plate section and said front circular plate section which provides a space between said rear plate section and said front circular plate section capable of receiving a flange of a flanged opening to be sealed and for receiving said blind flange and having sufficient room for the longitudinal movement of said blind flange in and out of contact with the flange of the flanged opening to be sealed;
• f) an actuator secured to said circular front plate, which actuator, is capable of horizontally moving said shaft and blind flange so that said blind flange can be moved in and out of contact with a flange of the flanged opening to be sealed.
