Infinite bronze exploit using industrialcraft 2 pipes

Can the issue be reproduced?
Yes

Issue
Industrialcraft 2 tiny pipes can be created using 3 bronze ingots(made into bronze item casing) into 6 pipes, however they are treated as medium bronze pipes in the Tinkers smeltery(according to JEI) and melt down into 18 bronze total, very quickly allowing for infinite bronze.

Tested it. melted 2 tiny pipes, and they produced 6 brozne

[NielsPilgaard]

So it is an exploit, but not as efficient as JEI states?

[survivalmonkney]

JEI is correct. PizzaAddict only used 1/3 of the pipes made. The original recipe for tiny pipes makes 6 pipes out of 3 bronze ingots/6 bronze item casing. Then the melting ratio is 1 pipe : 3 bronze, while the crafting ratio is 1 pipe : 0.5 bronze.

Maybe late but this also works for the tiny steel pipes, giving infinite steel. I'm on version 1.69
