Hi all, Sorry I couldn't access this forum in the past few days, but thanks for all the input. I am going to plan a FEA for this just to be on the safe side, because there is no guidelines at all in ASME for these kind of calculations.

Good morning, I have been tasked to calculate a flange thickness design check for the following procedure: We will be tapping a 1/4" NPTF onto a 2" 150# WNRF flange rim, after which we will drill a 1/8" hole through. I would like to know where I can go and look for the calculations to...

Good morning Gator, They will be using this item in service at a plant. Regards.

Good morning, Some engineers from my client's company have asked my company to change the location of jack screw holes on some flanges they have purchased due to the conflict in instrumentation on the pipeline. They want us to plug the jack holes with a bolt, weld them shut, machine the welding...

Good morning everyone, I am currently tasked to buy explosion proof thermocouples for an oil refinery. I would like to know what defines an explosion proof thermocouple, as my head engineers told me that we only need to ensure that the thermocouple we buy is sealed up at points so that no gas...

Thank you all very much for your help! We have readings of 8.1 and 8.2 on each weld respectively. And we will grind out the weld and re-weld them. As there is no definite procedures to prevent high ferrite count upon searching engineering literature, most of them explaining control is...

Good evening all, My client has specified a Ferrite number of 3-8 for weldments on a 316LSS pipe. Most of the welds fall into this range except for 2 welds. Hence I would like to know is there an allowance as I've read through ISO 8249 and there is no mention of this.

Good morning all, I have a question with regards to sizing an orifice line. I have a situation whereby the flow in the pipeline is 500kg/hr downstream of a valve =, of a certain gas, and my customer would like to restrict the flow to 200kg/hr. The question is, when I input the data into my...

Thank you very much weldstan!

Good afternoon all, My company has a few items of 347H which have been solution heat treated and need to be welded together. Can any welding experts here enlighten me on which welding rods I should use to weld these items together. I thank all in advance for their help!

I would like to know if anyone in this forum knows of any software which can accurately help me calculate the noise levels in a multistage orifice after the pressure drops in each plate? Thanks and I appreciate your help much!
