Far too small pressure rating. He needs steel pipe.I see 10-inch sch 40 PVC online at about $13 per foot, so there's $35,000
Edit: Something like in this picture. My guess is that the picture shows something like a 10 inch pipe with 10 inches of insulating jacket. But it's hard to get accurate size from the picture. Just laying bare pipe on the ground would cause dents and dents become weak points.
