Trade name I have called it by is just black poly. There are 3 pressure ratings (wall thickness) usually for this pipe 100 psi, 160 psi, and 200 psi.
For reference 1" schedule 40 pvc is rated to 270 psi.
2" schedule 40 is rated to 166.
Black poly is a ok product. It was pex before there was pex. Really popular in the 1970s. There are a lot of parks that are completely plumbed with black poly usually the 100 or 160 psi stuff. It was a break through product when you think of the other options in 1970 galvanized pipe where you had to cut pipe make threads, zero margin for error in install. Black poly was a mom and pop miracle peoduct in comparison. I would never use the 100, or 160 psi black poly it cracks to easy.
Black poly is simple to install just barbed fiiting and stainless hose clamp. My gripe is people buy the cheap 100 psi stuff… Home depot is selling it it must be good.
I would use pvc instead of black poly
