Experience with Lokring Fittings

[tommac]

Does anyone have experience with Lokring Fittings? Their manufacturer (

http://www.Lokring.com)

claims that you can save approximately 25% on an installed cost basis over a traditional socket weld system. The fittings are about 8 to 10 times more expensive than a socket weld fitting, but the installation labor is considerably less yielding the savings. I have tried to specify them on a job, but our construction types don’t want to use them, even though they complain about the problems with socket weld systems, such as welder qualification, and productivity.

I wanted to use them on a job also. Same problem - our construction guys wouldn't cooperate for several BS reasons. Real reason was - they didn't want the loss in revenue due to reduced construction cost resulting from no welding. I don't blame them for that but in this age of alliances and gainsharing etc. that argument doesn't cut the mustard.

Thanks!

tommac,
we have used dozens of them at our facility. process lines, 30 and 90 # condensate, process water with great success. they are very user friendly and to date no failures or problems. I won't say that they will replace a welder, being one myself, but they do come in handy when shutdown time is limited. I know another division of ours used them on a 400 ft fuming sulfuric acid line (oleum)@ 10 years ago and they are still using it today. cut installation time by more than 65%.
