ASME B31.3 (Process Piping) treats double-walled piping—commonly referred to as jacketed piping—as two (2) distinct pressure systems. Because the failure of the inner pipe (core) or outer pipe (jacket) carries different risks, the code requires specific sequences and methods to ensure the integrity of both.
One area that we commonly find during audits and assessments is the lack of complying with the state’s fire, building and mechanical codes. Often times we find that no one involved in the project(s) were even aware of these baseline state requirements for storing and/or processing hazardous materials.

The purpose of this project is to analyze a ruptured 1000 gallon NH3 tank to determine the crack initiation site (CIS) and the cause of the tank failure. On 11/21/2007 it was reported that, “a nurse tank carrying anhydrous ammonia exploded and pieces were found laying in the front yard of a farm just outside of Silver
Recent investigations conducted by the U.S. Department of Transportation, Federal Motor Carrier Safety Administration (FMCSA) on USDOT specification cargo tank testing and repair facilities have resulted in a consistent pattern of non-compliance regarding bench testing of Pressure Relief Devices (PRD). Specifically, cargo tank testing and repair facilities are either failing to bench test PRDs or
One of my favorite hazardous materials to work with is Chlorine (Cl2). And yes I know and no I have not been taking my meds! “Like” is probably a poor choice of words to us – Respect is probably more fitting in describing my relationship with Cl2. I have been working with this hazardous material
In 2015 we saw six (6) unloading accidents that involved serious injuries to workers, with some of the workers injured being those who were in the WRONG place at the WRONG time.

Repair work for liquefied carbon dioxide at a low-temperature storage tank (CE) in a steel mill was carried out. At the time, the main block valve below the safety valves was closed, while liquid CO2 remained in the tank. In addition, the heat source from the tank heater was still active. Therefore, in the tank,
The Pipeline and Hazardous Materials Safety Administration (PHMSA) is seeking to update requirements covering the use of excess flow valves in natural gas distribution pipelines.
