Diameter inch calculation
Inch Diameter Calculation
How are inches of weld in piping counted?
The number of diametral inches welded depends on the design and specifications of the piping system.
For example, a piping project typically involves the installation of pipe runs and fittings of different diameters, with each welded joint contributing to the count. It is necessary to consult the piping drawings, specifications, or project documentation to determine the exact number.
Here is a typical case of how to count inches of weld using the picture in the book "Estimator's Piping Man-hours Tool"
Number of Inches of Weld
Diameter Inch Calculation. The illustration above shows a discharge line starting at the discharge flange (2 1/2" diameter) of a centrifugal pump and then connecting by a 2 1/2" x 4" concentric reducer to a 4" diameter line terminating in an NPS 6" manifold.
To count the number of inches, count the welds according to the following table.

Man Hours Calculation
After calculating the man-hours obtained by multiplying the type of union of the line of the pipe by the consumption of hours to execute each type of union-consumption of hours that you extract from the eleven tables of consumption verified by the hand of the work of the e-book. "Estimator's Piping Man-hours Tool"; you need to adjust this total number of hours to increase or decrease it according to the conditions under which your project is being developed.
Here is an infographic that summarizes this concept.
