ISO-5167

Designed for the oil and gas industry, ISO-5167 is an easy-to-use software application for Windows that can help you give shape to orifice plates of a design as well as to locate the pressure drop of a flow (or vice versa).

From the installation procedure we can clearly see that ISO-5167 is outdated, and this aspect is also indicated by its interface, made from a normal window with a simple aspect that reminds of the Windows 95. Nevertheless, it is very easy to navigate.

You can perform a new calculation by setting a title, type (gas or liquid orifice, restriction orifice - gas or liquid), along with fluid: natural gas, air and oxygen (for gas), crude oil, water, methanol, monoethylene glycol, diethylene glycol or triethylene glycol (for liquid).

You can pick the calculation type (orifice size, flow rate or pressure drop), tapping mode (flange, D and D/2, corner, orifice and pipe material (carbon steel, stainless 300- or 400- series, other), together with the operating conditions (temperature, pressure, pipe diameter, downstream orifice pressure, flow rate) and natural gas or oil properties.

The results are shown instantly after clicking a button, and you can go back to make any modifications and recalculate data. ISO-5167 lets you print information, save it to file, as well as to set the measurement unit to customary or metric. There are no other noteworthy options available here.

We have not come across any issues throughout our evaluation, since the app did not hang, crash or pop up error messages. It has a good response time to commands and works well on later operating systems, although it has not been updated for a while. Excluding its dull interface, ISO-5167 serves its purpose and can be easily handled by those looking to make gas or oil orifice calculations.
