Water & air lines: Slip-on versus weld neck flanges ?
Water & air lines: Slip-on versus weld neck flanges ?
(OP)
Greetings all
Our plants currently utilize a line class specification for utility water and air applications that specifies the use of 150# FF slip-on flanges for pipe sizes 2-24".
Given that this is an old line spec (up for review), catering for non-lethal services, i was wondering whether anybody has any experiences which would justify NOT converting from slip-on to weld neck flanges (apart from the cost of ocassionally maching raised faces off)?
