I think I may have messed up. I connected a chimney cap from a Dura-Vent DuraPlus basic chimney kit to a 36" section Dura-Vent DuraPlus SS chimney pipe. I need to add in another section of chimney pipe and I can not get the cap off of the chimney pipe. Is there some trick to it?
How do I remove a simpson chimney cap?

They have little tabs, but mine twists off for cleaning.
can you unlock (twist) the last section of pipe, and add in a piece below the piece with the cap? we actually assembled our pipe from the bottom up.. great fun was had. by the time we got to the eighth section, we were standing in our chase, holding 130lbs of chimney up, stuffing it through the chase top hole 24' away, straight up.. did I mention it was fun?

Mine just pushed down on last section. No twisting involved. I just grab hold of the BOTTOM of the cap, one hand on either side and pull up with a side to side rocking motion. It is a tight fit so go slow and it will come off. I put it on in the same manner. Sometimes if there is a little creosote build up it can be more stubborn.
Good luck. We destroyed one cap trying to get it off. $42 later.... So when you look closely on the cap, there are little dimples that hold it. Try compressing the cap from teh side like an oval, and lift up on the ends and get them clear of the little notches then try turning it. No easy way that I've found, but some just seem to stick on better than others. Sledge hammer almost ended up on ours. Once it's apart, take a good look hoe it attaches and maybe mark it with metal marker for next time.

I'll try that.

It figures. I put the two pieces together on the ground so it would be easier carrying them up on the roof. I tried to take them back apart on the ground. It looked like I could take them apart if I had something like a tiny flat bar to pry the center pipes apart to get over the dimples. I pulled as hard as could without destroying the cap or top of the chimney pipe, any harder probably would pop a rivet on the cap or chimney pipe. I did mess up. I wanted to get the flashing down and cap on before it rained and thought I could come back a day or two later and add the additional 2' or 3' of pipe I actually need. If worse comes to worse I'll pull the chimney pipe back out of the ceiling support box and add in the pipe on the ceiling support box and redo the storm collar. If I'm careful I think I can slide the chimney pipe down through the flashing.
I appreciate the replies. I searched first and couldn't find anything on this specific problem. Thanks for your help.

I took a pair of pliers and mashed those damned tabs flat when I installed mine, on the thimble too, and used three stainless screws to attach the things. Piece of cake to take back off and reinstall after that. Those tabs are sloppy and stupid.

I actually twist mine off, they are a twistlock that only engages about an inch of thread. When I reassembled I actually put a bit of grease on the contact surface.

Twist counterclockwise and wiggle off. Easier said then done. I spent an hour trying to get the damn thing off. I think I will use BrotherBart's idea of flattening with pliers next time I clean. I like it. Thanks.
Why not untwist the top section that has the chimney cap on it. And put the new section where that one came off. Then put the section you took off back on. That's what I did on Mine.
