Model pipes of 6.0-inch outside diameter were selected because they could be tested at the West Jefferson facility using an all gas pressuring medium and remain within the noise and environmental protection limitations.\u003c\/p\u003e\n\n\u003cp\u003eThe types of backfill studied were air, sand or soil, water, frozen annulus of sand, and simulated permafrost.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367563292750,"sku":"220292","price":1495.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/ng-18-17-r01-examination-of-various-backfill-types-on-fracture-behavior-1","provider":"PRCI Store","version":"1.0","type":"link"}
