Rechner für Rohrversatz-Uhrposition & Rotation

This is clocking, not another travel calculator. Rise and signed lateral displacement define the offset plane. Its rotation from 12 o'clock is atan2(lateral, rise), then the entered datum is added and normalized to 0–360°.

Worked example: the starting 300 mm rise and 400 mm right lateral form a 500 mm true offset and place the near-end plane at 53.1° clockwise from top. At the far end, viewed back toward the near end, the same physical plane reads 306.9°. Always mark which viewing direction each clock value belongs to.

The wrap mark converts that clock angle into tape distance around the actual OD: circumference × angle ÷ 360. Because a fabricator looking back from the far end sees clockwise direction mirrored, the far-end reading is 360° − the near-end reading.

• Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
• Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
• When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

This establishes orientation marks only. It does not calculate elbow travel, weld shrinkage or fitting takeoff. The far-end conversion assumes both ends share the same physical top datum and the stated viewing directions; if your drawing uses plant north, pipe direction, or a different clock convention, reconcile that convention first.
