    API 650/653 Fillet Weld Base Metal Thickness w/Impact Testing

    You are inded correct. I also found the fine print in Section IX, Table QW-451.4........very bottom line: GENERAL NOTE: Supplementary essential variables apply when toughness is required by other Sections. Thank you for your response. CW

    API 650/653 Fillet Weld Base Metal Thickness w/Impact Testing

    I need a tank expert. In welding the annular floor plates to the shell plates, where floor plate thickness is 3/8" (P-No. 1, Group 1) and the shell plate is 1-1/4" (P-No. 1, Group 3) and impact testing at -25F is required................. If the PQR/WPS is generated via a V-Groove test weld...

    B31.3 Minimum Fillet Weld Size (special case)

    Here's one for you guys..................... Here is the scenario. The applicable code is ASME B31.3. A53, Gr. B pipe. 26” Std, hence, 0.375” wall thickness. Welding a split “Tee” fitting on for a hot tap operation. The split “Tee” fitting material is A516, Gr. 70 and is 1” thick (for the...

    API 1104 (20th Ed.) Branch Test Destructive Testing Specimens

    I have that PRCI doc and find it very helpful (for 20th ed.). I hope they follow suit and do the same for 21st ed. Seems a lot of places are hesitant to get onboard with the new edition.

    API 1104 (20th Ed.) Branch Test Destructive Testing Specimens

    I overhear a lot of stuff in my office. I'm always interested in the "correct" answers to most of these arguments. I did a search here already but am still a bit perplexed. Say a welder is taking a 12" "butt" and 12"-on-12" "branch" test (for procedure qualification and/or welder qualification)...

    Molten Sulfur Pipeline Integrity Assessment

    I ran across a situation yesterday that I haven't encountered before. A facility has a 2000' long 12" Std, Class 150 molten sulfur transfer pipeline. It operates at ~300F, less than 100 psig. The concern is that 3-4 years ago, it was noticed that the line had obviously undergone some thermal...

    Pumping Crude From a LACT Unitto a Pipeline

    I was orignally just trying to generalize, to my fault. I have a LACT Unit....FMC. The discharge of the LACT goes directly to a pipeline injection pump, toget the oil into the pipeline. he LACT Unit is Class 150 equipment, operating at relatively low pressures, say between 40-60 psig at the...

    Pumping Crude From a LACT Unitto a Pipeline

    So there is a crude oil storage/stock tank. It feeds oil through a LACT Unit via the LACT Unit charge pump. A backpressure valve at the LACT Unit discharge holds approximately 35 psig backpressure on the LACT Unit. The crude discharge from the LACT Unit goes to a "PD" pump where it is then...

    Monitor PLC Remotely

    I have a compressor station that is equipped with a "Station PLC" that runs everything. There is also a remote field office that monitors several of the station parameters via SCADA. In other words, an operator can be at the field office and look at a screen that displays the current...

    Fin Fan Process Cooler

    I'm sitting on the sidelines at work listening to two views on how to control gas temperature when using a "Fin Fan" type cooler. The concern is that in the winter the gas needs to stay at 85F. The new cooler is a dual fan model using two (2) 50 HP electric motors. (this in the South Texas...

    Reuse of Stud Bolts/Used Stud Bolts

    Beyond good engineering practices and quality issues in general (also PCC-1, Appendix N), are there any specific codes, regulations, guideline, recommended practices for reusing stud bolts for flanged connections on either pressure vessels and/or pressure piping? I do not want to use...
