<p>A seal assembly (100) for sealing a rotatable pipe (101), the rotatable pipe having an inner void (102) for transportation of high temperature medium therein, an axial direction (103), and a radial direction (104), the seal assembly comprising a swivel joint (105) having two axially opposing annular sliding surfaces (106, 107), the first sliding surface (106) belonging to a first pipe end (108) aligned in the axial direction and the second sliding surface (107) belonging to a second pipe end (109) aligned in the axial direction, the first and second pipe ends being rotatable with respect to each other, at least one bearing (110) being axially aligned for providing slidable movement between the first and second pipe ends, the bearing being positioned at the periphery in the radial direction of the pipe, a heat insulating shield (111) being radially positioned between the sliding surfaces and the at least one bearing and extending substantially in the axial direction, whereby the bearing is shielded from the high temperature medium and/or heat thereof.</p> |
