Whats the preferred material for running the water line from a pitless adapter on a well head 150′ to under slab of garage where pressure tank will sit? We usually use 200-PSI black plastic pipe {1″} in the trench but cant make very nice bends for coming up out of the slab with out using 90’%’s with hose clamps which I dont trust (particularily where Id never be able to get to them again). Black plastic pipe till i get to the footer then transistion over to..??? white plastic ? pex? copper . Thanks.

I think I'd probably put in a large PVC sleeve, say 3" or 4", and run PEX through it.
I haven't had any trouble with the black plastic. You just have to make the trench deep enough to have a large enough radius sweep.
I transition using a brass hose nipple with a male end, then a full-port brass ball valve, then whatever. I plumb with copper -- haven't tried PEX yet. On the hose nipple I use two worm gear hose clamps, marine grade, which are all stainless. Normal hose clamps use stainless only for the band, not the worm.
My installation is very similar. I've seen too many plastic 90º els fail. I used steel, double hose clamps, opposite direction. A deep trench with no hardware would be better, but mine was a retrofit.

One solution is to themoweld the connections.
Don't know what they use for the fittings, but that is what they do ends of the loops for gethermal heatpump systems.
What is the minimum bend radius of the pipe you're using, and how deep is the trench? If (for instance) the bend radius is 36 inches, and your trench is 36 inches deep, there shouldn't be any issue with the pipe coming straight up through the floor.
