Orbital Welding for Sanitary Piping Orbital welding in Sanitary application is extension to tungsten inert gas (TIG/TGAW) welding. This type of welding is default in piping, which the application demands Sanitary or super clean application, where cleaning is done with CIP/SIP. The pharmaceutical industry currently uses orbital GTAW/TIG welding almost exclusively. This produces welds of […]
Metals in Pharma/ Food Industry As we know, the out put from these industry are directly consumed by end user, and it impact either health value or patients safety! Its prime importance that the metal used in these industry ensures no impact on quality of products and also ensures minimum maintenance. Many time, manufacturer prefer […]
Ergonomics design for Push Trolley (System on wheel, managed by Pushing) As per HSE, Pushing and pulling of loads is a way to avoid manual lifting and carrying of objects such as by putting the load on a trolley. Why its important to study? and even design? Statistics can be seen below that give you an […]
Be in whatever field you are, you come across trolleys in one form or other. Trolleys, some time stuck, sometimes with broken wheels, sometime hard to push and sometimes its better keeping them untouched. My profession given me opportunity to design one trolley myself. And I grab the opportunity by both hands. Here, I’ll share […]
Recently I came across this requirement of calculating heat required to heat air (for AHU), I came across two simplified formulas, as follows. Please also note the learning from this workout at the bottom! Learning! for delta T, Centigrade vs Fahrenheit are different! I was thinking, as long as its Delta (Difference between two temperature), […]
So, we have covered Destructive testing in my last post, now something on Non-destructive testing. There are Numerous Non-Destructive tests used to evaluate the base metal to be joined as well as completed welds. However these all NDT shares several common elements, these essential elements are summarized below: o A Source of Probing energy or […]
I’ve covered, welding and weld defect in past posts, what I missed completely is the testing of Weldments. One of the purpose of effective quality control program is to determine the suitability of a given base metal or a weld to perform its intended service. When It comes to testing, we have two type of […]
During design of pressure vessel, I came across this issue number of time. Unfortunately, ASME VIII Div.1 doesn’t give a clear picture, whether to add the undertollerance in the min. required thickness as calculated by ASME VIII Div.1 ASME VIII Div. 2, give a clear cut understanding on this issue, can clears all ambiguity. (Clause […]

Tube hole finish affects the mechanical strength and leak tightness of an expanded tube-to-tubesheet joint. In general: (1) A rough tube hole provides more mechanical strength than a smooth tube hole. This is influenced by a complex relationship of modulus of elasticity, yield strength and hardness of the materials being used. (2) A smooth tube […]
