Here's what I did to the pipe:

80 with a bosh hybrid rotary/random
150 with the bosh
320 by hand
400 by hand
600 dry
600 wet
800 wet
1000 wet
stainless steel #000 ( or 0000 i'm not sure) with metal polish
2000 wet
PB 2.5 with orange pad with rotary
PB 1 with orange rotary
Duragloss metal polish by hand
then washed with Pb S&W
1 coat of PB Wheel Sealant
1 coat of #476.

When I show the result, most people think it should be more chromed with better reflection.. What Should I do??

You need to keep on sanding. In the first after pics there are still casting pits. Your problem is you are moving too fast. You want to fully remove all casting pits first then progressively sand up. You also need to make sure you are removing your previous sanding scratches with the next grit level. Sand horizontally with one grit and vertically with the next to help see if you removed the previous scratches. Polishing cast aluminum is all in the sanding and not so much the metal polish. A good sanding job should look sorta like your current finished product.

Look in youtube for polishing jewelry

I will check for that. I'm surprise that only a little polishing paste could do all the differencem( rouge).

It is not a paste but a bar that you hold against the spinning wheel. There are several different types but pretty much any type will polish alluminum. There is tripoli that will remove scratches and prepare the piece for a mirror finish
