Calculadora de Reloj de Rotación de Desvío de Tubería
Convierta los desvíos vertical y lateral en posiciones de reloj para el extremo cercano/lejano y marcas de circunferencia a partir de un datum establecido.

Normally 0°. Use this to carry an established seam or fitting datum.
Angles use a clock-face convention: 0° at 12 o'clock, increasing clockwise. Near and far values describe the same physical plane from opposite viewing directions.
How it works
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°.
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.
Current-input example
The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.
- Vertical offset (+ up)
- 300 mm
- Lateral offset (+ right)
- 400 mm
- Actual pipe outside diameter
- 168.3 mm
- Top datum clock angle
- 0 deg
Primary result: Near-end clock: 53.1 deg.
Before using the result
- 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.
Limitations
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.
Frequently asked questions
Can the lateral value be negative?
Yes. Positive means right and negative means left when looking from the near end along the direction of flow.
