Using multiple reducers

Using multiple reducers

(OP)
Any guidelines on using multiple reducers for drastic line size changes?
Example 8"x2". I would go 8"x4" and 4"x2". Is this OK or are there specific rules to follow.

Thanks.

RE: Using multiple reducers

Use what is available in ANSI B 16.9 table 12. in your case it is 8 x 4, 4 x 2. even 8 x 6 would need a 6 x 3, 3 x 2.

The ycan look quite odd, especially if you've got eccentric reducecers, but it's allowable.

For really big changes (say 16 x 2) you could use tees, but it is fairly rare to go for that sort of size change.

No problem.

I don't know that it is illegal, but it seems stupid. Why wouldn't you use a weld-o-let?
