Hi, what will be the approximate length of line? You need to see that the line is not pressurized, If there are any vent valves on the lines release pressure and keep them open until welding of support pads/shoes is done. As Raj said preheating is required. (In the view of hydro testing If there are enough supports on the line regarding stability of line hydrotesting can be done and support pads/shoes can be welded latter and no need of any further hydrotesting) I do not think for every fabrication step there will be a code Ohm-Srinivas ohm guru namasivaya --- On Thu, 1/7/10, rajagopal kannan <rajagopal.kannan@gmail.com> wrote:
