Calculating the Axial Positions Trip Set Points from a Pump Axial Positions Datasheet
A typical axial position datasheet for a canned pump would look like the table below:

Check Valve Restricting Flow
I have experience in a batch processing unit project where saturated LP steam (2 barG, 133 degC) couldn’t lift the piston inside a 1-inch plug-type check valve, causing the steam to be completely blocked.

Hunchback / Drooping Curved Pumps Switching
When developing a Mechanical Run Test procedure, pump curves are usually attached as a part of the procedure. When plotting the head against flow, a typical centrifugal pump curve usually indicates a smooth decreasing trend (fig. 1).

Quickly find steam saturated temperature when the pressure is known by using double square root method
Probably you sit in a meeting and you need to quickly estimate the temperature of saturated steam using a calculator instead of finding it in a steam table such as the IAPWS-IF97 formula. You could actually do that pretty accurately by doubling the square root of that steam pressure in barA as shown below:

First Post
Hi there! I’m posting this just before being dispatched to do commissioning at one of the largest downstream oil and gas projects on the planet. I’m sure I’ll be learning a thing or two about pre-commissioning, commissioning, and startup, so I plan to share it here. I hope this turns into a long-term thing where I keep sharing what I learn along the way. Thanks for reading, see you in the next post!
