Abstract
A sealing arrangement includes: a first pipe and a second pipe, which are arranged substantially adjacent to each other in a flow direction and together form a line, the first pipe having a first end and the second pipe has a second end, the first end enclosing the second end at a radial spacing; and a sealing sleeve comprising a sealing material, the sealing sleeve being sealingly arranged under radial elastic preloading in a gap formed by the spacing and sealingly contacting an inner circumference of the first pipe and an outer circumference of the second pipe.

A sealing arrangement, comprising:
- a first pipe and a second pipe, which are arranged substantially adjacent to each other in a flow direction and together form a line, the first pipe having a first end and the second pipe having a second end, the first end enclosing the second end at a radial spacing;
- and
- a sealing sleeve including a thermoplastic element embedded in an elastomer, the sealing sleeve being sealingly arranged under radial elastic preloading in a gap formed by the spacing such that the elastomer sealingly contacts an inner circumference of the first pipe and an outer circumference of the second pipe, wherein;
- the first end has a rim protruding radially outward in a shape of a collar, and
- the elastomer of the sealing sleeve is configured to surround the rim of the first end,
- both the thermoplastic element and the elastomer are arranged between the first pipe and the second pipe in the gap, and
- the thermoplastic element extends axially within the gap and includes a radial protrusion extending radially away from the second pipe.
A sealing sleeve, comprising:
- a sealing material configured to seal a first pipe and a second pipe together;
- a clamp-shaped holding claw comprising an elastomer and configured to positively engage a first end of the first pipe and wrap around both inner and outer radial surfaces of the first end, the holding claw being arranged at one end of the sealing sleeve;
- an axial stop arranged at an other end of the sealing sleeve facing axially away from the holding claw, the axial stop substantially protruding radially inward and having an inner diameter which substantially corresponds to an inner diameter of the first and second pipes;
- and
- a substantially hollow-cylindrical casing in an axial direction between the holding claw and the axial stop.
