50% VS 100% Bolting for Flange Protection | WHAT IS THE DIFFERENCE?

Apr 26, 2022


50% VS 100% Bolting

Now 100% and 50% bolting are a terms used with appliying flange protection to piping. 100% bolting is demonstrated when our flangeBUMPER has 100% of the bolt holes secured with a multiNUTS and screws. Doing this gives to the most protection and is essential for long term preservation. Typically long-term preservation is up to 24 months and over.

50% bolting is when only half of the bolt holes are secured with a multiNUTS and screws. When you do 50% bolting you want to make sure that you are ALTERNATING the multiNUTS and screws. This method allows for the flangeBUMPER to be more secure all the way around. This method of bolting does save you time on big flanges due to all of the bolt holes, but it is not ideal for long-term preservation.
