    Flammable liquid Presure vessel and piping inspection

    MJ, I agree with what you say , no doubt. The point I`m trying to make is that the government should be involved in all safety aspects of plant operation. Leaving it up to the plant management is gross neglect on the governments part. Making sure that employees wear safty glasses and ear plugs...

    Flammable liquid Presure vessel and piping inspection

    MJ ,thanks again for our response, the issue at hand is the lack of inspections performed on equipment that has potential for harm to human life if there is a faillure.

    Autogenous weld cracks in 316L

    If your penetration is 50% your only getting about a .043 filler and of this .043 filler how much of this filler is good metal, your not using any backing gas? The problem seems to be thermal expansion causing the cracking. You simply do not have enough good metal to hold the joint together...

    Weld Shrinkage

    With the amount of welding , fabrication and all the expense that goes with it, I wouldn`t rely on guess work . A mock up of the joint configuration (gap size) material and welding process is the best and safest way to go. A precise before and after measurement will tell the story.
