I have a valve that has been failing continuously due to leakage of the seals, therefore would like to recommend a new valve as a replacement. Piping class: B1
The current installed valve has the following specs: Designed to API 6D / API 608
Body material: ASTM A-216 WCB
Ball Material: 316SS...
Hi Guys -
I currently have a floating ball valve that operates in a Mono Ethylene Glycol (MEG) Regeneration Package. The piping spec that it is on is B1E (Carbon Steel, Pressure Class 300, Corrosion Allowance 3mm). I would like to replace it with a new design and am stuck with two options. If...
Thanks again Avalveman!
I am in the oil & gas industry, we deal mostly with LNG Gas so technically the systems are supposedly clean.
Most of our Pilot Operated SRVs have failed a leak test compared to Bellows and Conventional type (which have failed either due to leakage or did not "pop" or...
Thanks Avalveman
The scenario is that we have never had very high failure rates of PSVs in our plant. Unfortunately after a very high magnitude earthquake, we have seen an increased number of failures.
Would the type matter? i.e. Conventional, Bellows, Pilot with regards to vibration...
Hi Guys - I have two questions about PSVs and the two testing methods i.e. in-situ and bench testing.
1. If a PSV fails an In-situ testing, would the results be accurate enough as compared to bench testing results; especially with set pressure and CDTP (Cold differential test pressure)?
2. If...
