Flange Guard: What is it?

I stumbled upon flange guards not when I was a process engineer, but rather recently when a practical student mentioned about it few months back. I goggled right away and found the answer. I realized that it is something to do with the joints and threaded fittings in the form of flanges, unions, T joints and elbows, sockets or expansion joints for any piping system.

Then I asked myself why flange guard was not installed in the plant I worked before. It was then that I realized that it is more required for a plant with critical and hazardous chemicals. My previous plant was more on edible oil and maybe that was the reason why I believe there was not flange guard installed.

Anyway let me just share slightly more on what is flange guard.

Flange guard is also known as flange spray shields are used in a range of industries to prevent hazardous spray outs from leaking flange joints and dangerous fluids such as acid, oil or steam. Flange guard cannot contain leak for an indefinite time, but are used to prevent fire and explosion which may cause death and injury.

There are several types of flange guards which are explained below:

·        PTFE Flange Guards

PTFE flange guards are made of multiple layers of Teflon coated fibreglass fabric. Teflon is resistant to most of the chemicals and Fibreglass provides strength to the fabric.

·        Stainless Steel Flange Guards

Stainless steel flange guards are manufactured from SS316 steel. These shields have a steel mesh welded inside. The mesh diffuses the pressure and gives a safe discharge to the leaking fluid. These Flange spray shields are used on high temperature and pressure flange joints.

·        Clear Type Flange Guards

These Flange shields have a transparent central window to provide easy visual inspection of flanges. This helps in easy leak detection without dismantling the shield. The Central window is made from ETFE in the middle which has a high tensile strength and PTFE on the sides.

I hope you are clearer on what flange guard is about. It’s an excellent tool for providing safer working environment and lost prevention. If you have any questions, feel free to ask me in the comments section below.

Hang Out Zone #40 "Engineering Practice Experience Sharing"

This is UTM Faculty of Engineering's Hang Out Zone #40 talk by me titled "Engineering Practice Experience Sharing".

In this talk, I shared in about 1 hour an example of engineering career sharing, which was my own personal experience. The case study of engineering career dwells around my adventure in the (1) oil and gas, and (2) oil and fats industry. It' difficult to share the experiences in 1 hour, but at least this is something that can be considered a sneak peak of one or two of the numerous engineering careers. Enjoy. Feel free to subscribe and request to get notified for all my videos.

My Daily Task as a Chemical Engineering Academia

Hey guys! How are you doing?

It has been quite some time since I freely write here in this very first blog of mine. This blog is my first and early success and I will never abandon this blog. I have been writing in another official work blog (the blog image is below and the url is people.utm.my/zakiyamani/) on a daily basis, but few days ago I thought that I should not fully ignore this blog and that's why I am back here doing some sharing. On 1st January 2020, I started to write on a daily basis all the official task that I am doing as a chemical engineering academia. 

Reason and Rational

The reason I am doing so is to share information, share working experiences and share insights on becoming a chemical engineering educator. Many people still think that an educator task is mainly to teach and lecture. But, that's more than just lecturing. That's the main reason I started sharing my official daily task. If you are interested to read it, you can click here

In many typical days, there are plenty of task that I need to perform, but for the sake of simple sharing, I would just select one of the official daily task. Sometimes, if there are more than one unique tasks, I will just state two or several of them. 

On top of that, I feel that it is nice and good to review back and reflect back on what I have been doing in the past. Believe it or not, often when I clicked my way back to several months in the blog, I forgot that I have done this and that! Hence, it is good to have a casual record on my daily log work, stating only one of the important things that I have done on a particular day.


The main challenge on my mission is to be able to update all the selected official task daily. Sometimes, the working days seem hectic and I missed out updating it. But, I try to just put the title or main task and publish it. Then, when I have the time in future, I will look at the pending post and knew immediately what I should continue share. 

Another challenge is to have the bold and courage to state that there are days that I don't do any official task. Yes, that's true, very true. I am normal human and I do need a break once in a while although if you notice, I still record something to do on many of the weekends. But when I am so overwhelm with work on a particular week or if I am on a trip to my hometown, I will truthfully declare that I am not doing any official task. Yes, my story, my statement need to be realistic and true. Once in a while we need to break the pattern, not only working all the time.


At this point of time, I have already have up to Day 282 Task. If i am to complete this year's daily task recording, it will be 366 days. I am wondering if you have any ideas or recommendations, please do not hesitate to inform me. I am very glad to read and consider your idea/recommendation.
