Hi,
Has anyone got any good reference material in relation to how to assess if it is safe / or able to weld a collar onto a live water line? Am looking at welding a 20mm collar onto a 300NB water line, materials are: Collar = A516 Gr 60, pipe is A106 Gr B. Pressure in line is 6600KPag, with...
Does anyone know if there's a standard arrangement for putting a high point vent into a #600 ANSI flange? I need it as part of a hydro test for a 300mm dia line.
If not, I was going to drill a hole near the top of the flange and weld some sore of weldolet that is ablt to be welded to the flat...
I looked at API 14E which relates to the errosion in relation to velocity, but is not 100% suitable to my situation. Also found this NORSOK standard which mentions 200,000kg/ms^2. What do you think? I'm not too interested in the long term process, just the equalisation around the 900mm...
Does anyone know where I can find any information in relation to the max velocity in gas pipes/ pipe is steel, delta P=12MPa, Dia 100mm. I have a reference of kinetic energy of 20,000kg/ms^2, which looks like it should be 200,000kg/ms^2!!
The line is a by pass line around a 900mm ball valve.
