Well casing sizes. This design uses progressively smaller sizes, such as 13 3/8 inches down to 4 1/2 or 5 inches for production casing, to reach the deepest zones. Next is the nominal weight which is the average linear weight of the tubing that includes the connection CRESLINE WELL CASING SHOULD BE INSTALLED IN ACCORDANCE TO THE GUIDELINES AS STATED IN ASTM F480 AND THE SELECTION AND INSTALLATION OF THERMOPLASTIC WATER WELL CASING MANUAL PUBLISHED BY THE NATIONAL GROUND WATER ASSOCIATION. Eagle LocTM Well Casing meets the Stiffness, Flatte-ning, Impact and Puncture test requirements of ASTM F480 and is available in 4"- 6" SDR 21, SDR 17 and SCH 40. Casing provides locations for the installation of blowout preventers, wellhead equipment Diameter of the upper pump housing casing must provide sufficient clearance between the column pipe and casing to permit installation of a sounding tube or air line to measure depth to water. Different sizes cater to different hole dimensions. Nov 9, 2025 ยท As the well deepens, the next string of casing, such as the surface casing, must be small enough to fit inside the previous string, creating a telescoping effect. Well Casing and Diameter The well casing, typically made of steel or PVC, lines the borehole and prevents it from collapsing while keeping contaminants out of the water supply. Explore various sizes and specifications of PVC well casing and SDR pipes. Much larger steel casings are used in high capacity community water wells, commercial or agricultural wells, and in some other water wells. How to Measure Your Well Casing for a Well Seal Place the end of your measuring tape on the inside of the pipe and measure to the inside of the opposite side, that number will correspond to the correct well seal size. mctxb fxj quuxq jwzmmom bnruz hkaehqikw xwpirnvn caxfqk bfueio vsbr
