Hi, I'm looking to better understand the degradation modes in a system that I'm currently analyzing.
This is a (High Temp Hot Water / ASME IV Boiler) HTHW system with multiple boilers that operate in a parallel configuration between a boiler inlet header and a boiler outlet header. The system...
Hi, we're currently in the process of evaluating service intervals for PSV's throughout a facility which is located in New Brunswick, Canada. This is a CSA B51 jurisdiction and I have a good handle on the service / test / inspection requirements for PSV's in different services.
This site...
I've proposed this solution to them. The question for me here is if the section 9.11.2.2 requires this upgrade or not? Are there any code clarification questions published for this?
A storage tank we're currently working on has an arrangement per the attached image.
They're a very picky client and pretty much require any recommendations to be written into the code. My concern is that there is zero way to inspect underneath this column bearing pad. Additionally, any lateral...
If you're asking about how many radiographs are required to be considered "spot" radiography, for a new-construction tank, see API-650, Section 8.1.2. Figure 8.1 gives you a good idea in determining this.
There are also limits placed on the size of tank that can be constructed without...
I have a client that is very resistant to any "best-practice" type recommendations. I'm wondering if API provides any recommendation on the periodicity to how often water draw-off nozzles should be checked? Currently they don't do any and they won't accept that the pitting in the bottom shell...
You won't see issues so long as the area isn't wetted. I've worked in an offshore environment with stainless steel pressure vessels bolted to carbon steel support legs which did see corrosion but even in that very long process, galvanic corrosion cells were readily apparent and were easily...
I have three pressure vessels, constructed of 304SS and 316SS which operate at 50psig and contain hydrophosphine product with a Nitrogen blanket. As this is a highly flammable & toxic product, our client is looking to propose non-intrusive NDE in lieu of internal inspections.
I'm wondering if...
