*   These wall thicknesses in Standard Line Pipe may be threaded and coupled or welded.

TABLE III MINIMUM STANDARDS OF DIMENSIONS AND WEIGHTS STANDARD PIPE AND LINE PIPE *

20 OD	20.000	19.438	0.281	59.23
*   This lighter weight pipe, meeting ASTM Standards A-53 or A-120 and API Standard API-5L, is suitable for welding only.

 

TABLE IV MINIMUM STANDARDS OF DIMENSIONS AND WEIGHTS STANDARD WATER WELL CASING *
Nominal Size in Inches	Diameters in inches		Wall Thicknesses in Inches	Weights in Pounds per Foot
	External	Internal		Plain Ends	T. and C.
3½	3.500	3.250	0.125	4.51	4.60

5½	5.500	5.192	0.154	8.79	9.00
*   Standard water well casing may not be used as an outer casing unless backed with cement grout at least two inches thick. A welded 8-thread transition fitting must be used to attach a pitless adapter to this type of casing.

TABLE V MINIMUM STANDARDS OF DIMENSIONS AND WEIGHTS STANDARD API CASING *
Nominal Size in Inches	Diameters in inches		Wall Thicknesses in Inches	Weights in Pounds per Foot
	External	Internal		Plain Ends	T. and C.
4½	4.500	4.090	0.205	9.40	9.50

11¾	11.750	11.150	0.300	36.69	38.00
*   Because of the type of steel used in fabricating API casing, it should always be threaded and not welded.
