Hello All,
We are considering using a pump constructed with ductile cast iron components. Could you please confirm if there is a maximum allowable brine concentration for pumps made from ductile cast iron?
Dear Engineer,
We have recently observed premature failure of the ozone diffuser gaskets. These gaskets are stocked and used accordingly. Operating temperature is around 70 F.
Historically, they have lasted around 3–5 years in service but we have started seeing failures after just 1 year...
S Jana:
Is this a wet screw compressor or dry compressor? Does the process fluid (gas) mix with the oil that is contaminated with water? Is it radially split type or axially split type? Is it located indoor in a room or outdoor in the field?

Is this question for a general curiosity or for an actual project? If it is for a project, do you have a completed datasheet covering all details including flow requirement, product viscosity, temperature, pressure and the factors? The pump material will obviously depend on these...
Hello Engineers,
I recently received my PE license in Mechanical Engineering and was contacted by a recruiter for a project involving drawing review and stamping. The assignment is estimated to take around 50 hours with a fixed payment.
On one hand, I feel confident in my ability to check the...
Hello ENGTaL,
The term "Static equipment maintenance engineering" is broad and can refer to many different things. Maybe you can clarify what specific area you want to focus on? For example: Post-weld non-destructive examination (NDE) techniques for shell and tube heat exchangers used in...
Hello Christine74,
Thank you for your detailed message and for suggesting more reading material. Your specific insights were really helpful. A little purple star for you!
Hello r6155,
Thank you for your reply. I agree that discussing my experience is important, but I disagree with your view...
Hi Georgeverghese,
Thank you for replying to my post! You definitely deserve a purple star!
I am currently reading the TEMA standard and it is proving to be very helpful. I have to say, the standard is written in a way that is easy to understand. Thanks again!
Hello Engineer,
I am preparing for an interview for a mechanical design engineer position at a company that designs and manufactures shell and tube heat exchangers that operate under high pressure, up to 3000 psi. This is a mid-level role reporting to the engineering manager. While I have...
Hello everyone,
Thank you for replying to this post. I really appreciate it.
As advised, I am currently learning the basics of Python and creating simple programs (see example below). My goal is to automate repetitive tasks at work. Could you guide me on the next steps?

Hello fellow Engineers:
I am seeking your opinion. I am full-time mechanical engineer with 12 years of experience. As a side interest, I am considering learning programming languages like Python. I am interested in finding an unpaid internship in programming where I can learn and apply my...

Here is how you should measure runouts on such a long shaft.
-Mark the bearing journals on shaft (also called bearing fits) with sharpie.
-Place V blocks under those bearing journals (not on the ends). If the bearing spacing is too much, you may need to install more spiders (also...
Jackelmo:
A very common shaft material (and the one we always use) for boiler feed pumps is 410 SST Cond T. This may be cheaper and readily available than the one you are considering (A276 S42000). In case you haven't bought your shaft material, you can get a quote for 410 SST Cond T. Just my 2...
Thank you everyone for interesting and informative responses. I checked the link and realized how critical the design of these cranes are. Thank you again.
I have another question here. Which industry do these cranes and hoist system fall into? What are you views on the future forecast of...
Dear Engineers,
I recently received a job interview call for a mechanical design engineer position, who will be working to design overhead Cranes and Hoists. This company designs and manufactures overhead crane and hoist systems along with support structures & custom mechanical equipment for...
