If you are faced by a task to calculate diameter of a pipe, then it is possible to make it by means of simple geometrical calculations. Any pipe represents a cylinder and has two diameters – external and internal, they differ on the doubled pipe wall thickness. Calculation can be made in different ways, depending on the available data.

1. In the most general case, diameters of a pipe with thickness of a wall of T can be counted, having measured length of a circle of its section. Let this length be equal to L. Then, on a circle length formula, its diameter will be ravend1 = L / P where L – pipe section circle length, P = 3.14takim image, D1 is an external diameter.
2. Length of internal diameter of a pipe will be ravnad2 = d1 – 2 * T where T – pipe wall thickness
3. If the piece of a pipe is available and its length and surface area are known, then diameters can be calculated, using a formula of the area of a side surface tsilindrad1 = P * h/S where h is length of a pipe, S is surface area, P = 3.14d2 = d1 – 2 * T where T – pipe wall thickness
