Reply:this is my first post on here.  i have enjoyed this forum for a lil wile now.i posted a question i need help with in the general welding questions area about arc gouging.  any advice is great.thanksmason
Reply:Nice job, makes my back hurt just looking at it..wish i could help you the gouging question, sorry.
Reply:Looks good, I like the bypass after the trap, I should start putting those in instead of "test" valves to the floor.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:Nice !  Question, is that steam reducing valve 2'' ? We would have installed 2'' 300  unions so  you don't have to unbolt the flanges. Are there gauges on inlet and outlet of reducing valve ?Is that compression fittings on the copper ???
Reply:Looks like a swagelock to me, thats what I use. If you look at the valve itself it appears to have unions on it.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:foto two i would say go back and roll those y strainers till the blow off was at the bottom..and are you sure the control valve mfr is ok with them rolled   like they are? cant quite see, is that one eccentric reducer fob and the other fot??Last edited by weldbead; 01-20-2013 at 04:27 PM.

Reply:Originally Posted by mason702on the stainers- you want them on the side on steam supply so condensate will pass rite through them with no trouble. the control valves are really tall and didnt have the room, to turn them up.   the paper work stated you can put them on the side if you loosen stem and turn motor and controls the way i got them now.   but your rite on some valves have to face up.the system has been on and working good for a few weeks now,  no issues
Reply:very nice work. very neat. i have a question. in the third pic on on the welded elbow there are what looks to be like grooves ground into each side of the weld joint. or am i seeing things?i.u.o.e. # 15queens, ny and sunny fla

Reply:I'm curoius.  What kind of steam plant?  We have a Hurst 250 horsepower bio-fuel scotchback.

Reply:pressure is 30 psi,  and this was and addition onto a hospital in vegas.   in the penthouse were 4 air handlers and heat exchanger, pumps ect......
Reply:Originally Posted by mason702yes,  i like to hit the sides with file or cutting wheel.   i think it looks clean
Reply:If you hold the correct amount of time and a correct arc length there should be no undercut on your cap. Jmo
Reply:im not hiding any under cut,  just think it cleans up the weld really nice.  like outlining some art work with some dark lines.

Reply:[QUOTE=mason702;2168571]on the stainers- you want them on the side on steam supply so condensate will pass rite through them with no trouble.  no i do not ..with the baskets in the  horizontal crap will accumulate across the pipe..in the vertical it will drop into the bottom where it can be blown out..its nice to put a hose adapter after the blowoff valve  so the blowoff isnt a mess, top one appears to be aimed at the valve actuator..and there should be a steam trap at the bottom of that supply riser, so what condensate are we talking about?
