Hello everyone.
I've been seraching the Interent for a while. Trying to figure out the ,meaning of letter "K" stamped on castello pipes.
Everybody say that "K" is used for non-smooth pipes to designate size. More K's means bigger pipe.
But, there are two explanations for smooth finish pipes.
Some articles say "K" means a combination of grain quality and size for smooth pipe, while some people say it only indicate grain quality not size.
Could you tell me which one is the correct answer?
Thank you!
