Today I finally had enough of just sitting around doing nothing so I decided to wrap my HFC pipe.
Started a little after six O clock and the weather was perfect too.
Gathered everything up I need: HFC pipe, gloves, goldbond to make the gloves slide on, metal locking zip ties, metal heat tape, metal snips and heat wrap.
The trick is to have the heat wrap soak in some water for an hour or two. By doing this it becomes more flexible and easier to work with.
Since its a small piece of piping I had it clamped to my work table.
When you start to wrap I always use a plastic zip tie first to hold the end in place and then later I replace it with the metal ones.
Then work your way making sure to pull tight and to overlap atleast 1/4th as you go along. Do your best to make it around the O2 bungs and other areas.
Now heres the hard part. The situation is that youve got a very slippery wet wrap that wont hold on to areas that slope up like this catalytic section. So the trick is to cross hatch the wrap by overlapping in an X configuration. This way the wrap will cover the entire area without slipping off the corners.
It should look like this when your finished with the cross hatching of the converter. Finish wrapping the rest all the way to the end of the pipe.
Now to finish and tie up the ends all you have to do is pull the wrap a little back up the pipe and away from the pipe end. Use your heat rated exhaust tape and make one or two passes around the loose end of the wrap. Then take your metal zip tie and place it on there very tight.
You then cut the unused portion of the metal tie off. Your going to have a very sharp end sticking out so what I do is take some pliers and roll the tip inward.
Heres what it looks like when its all finished.
These steps can also be taken when wrapping your header system or anything for that matter.
Note: If your going to coat the wrap with some ceramic spray or any other type of sealant/protectant, you want to make sure its completly dry. You can do this either by running the engine so the water in the wrap boils off or if you have time you can let it air dry for a week or two.
