Abstract: A pipe seal is disclosed which comprises a main body portion (1) adapted to be fixed to the wall (12) of a chamber, tank, or the like, a face plate (6) adapted to be secured to the body portion to surround, in use, a pipe (14) to be sealed, the body and face plate between them housing a deformable member (9) in contact with a seal (8), such that, on forcing the face plate toward the body portion, the deformable member, in use, deforms and presses the seal into sealing contact with the pipe. The design of this pipe seal allows the pipe to enter the chamber wall at an angle of, for example, up to 12 degrees from a right angle. Hence the end of a pipe could generate a cone of movement with an included angle of 24 degrees. The seal therefore permits considerable positional movement of the pipe to allow connection of the pipe to its termination point within the chamber.

Abstract: For sealing an annular space or space (4) between an opening (2), in a wall or similar member (1), and an object (3) extending through the opening (2), at least one sealing element (6) is placed in the annular space (4). Initially, the sealing element (6) is placed in the compressed state between the wall (1) and the object (3) and subsequently is released from the compressed state to an expanded state. For this purpose at first, the sealing element (6) is compressed by a sheath (7) which, after the sealing element (6) is positioned in the annular space (4), is destroyed and makes the expansion of the sealing element (6) possible.
