A tubular screen for screening of pulp suspensions comprises a mantle wall (1), which is provided with screen passages, and external support rings (6), which reinforce the mantle wall so that the latter is resistant to and is not deformed by dynamic forces during operation. Each support ring is designed with a conical surface (7), which abuts and presses directly or indirectly against the mantle wall (1). |
