I am sure many of you have heard the old saying… “it’s just common sense” when it comes to applying PTFE (Polytetrafluoroethylene) tape, often called “thread sealants” or “plumber’s tape”. Yet this practice is a critical skill for ensuring leak-free connections in threaded piping systems. While it seems straightforward, the direction and tension of the […]
On the ASME Form U-1 (Manufacturer’s Data Report for Pressure Vessels), the information regarding Postweld Heat Treatment (PWHT) is typically found in Line 14.
An ASME B31.3 welding quality assurance (QA) program must cover the full lifecycle of a weldment, from procedure qualification to final testing, to ensure structural integrity. It serves as a mandatory framework for contractors to demonstrate that their processes and personnel consistently meet the minimum safety requirements for process piping. The QA program must include the following:

But since the IFC no longer covers refrigeration, how does NH3 get covered under the IFC? Is it flammable, toxic, or corrosive?
In ASME B31.3, the number of welds that require visual inspection depends entirely on the Fluid Service Category designated for the piping system. Because visual inspection is the primary quality control method, the requirements are strict. For the vast majority of process piping (Normal Fluid Service), 100% of the completed welds must be visually inspected.
This traffic camera footage of a Bromine Release in Russia is some of the most amazing HAZMAT footage I have ever seen. The officials at the time and when I reported it in the Incident Alerts stated it was a “small release from a pail”. Now with this footage available, we can clearly see this
