4''-24'' Ball Joint Pipe

AMERICAN Ductile Iron Flex-Lok Boltless Ball Joint Pipe For Water, Sewage and Other Liquids 4"-24"

The following table shows suggested water pressure ratings with thickness designations and weights in accordance with applicable requirements of ANSI/AWWA C150/A21.50 and ANSI/AWWA C151/A21.51. It is intended that the ultimate determination of suitable thicknesses should be made by the design engineer with consideration of both installation methods and ultimate service conditions of the line.

ADIP Table No. 10-1

Notes:
*The 20'-6" laying length is subject to trim pipe allowance in accordance with AWWA C151; also, this is the fully homed or inserted laying length of 4"-24" Flex-Lok pipe. In installations where 4"-24" joints are pulled or extended to metal-binding contact of joint-locking members, some slight additional laying length will be gained as a function of the removal of joint assembly space. Contact AMERICAN when lengths are critical, or when it is necessary to locate ball joints at specific stations, etc. The joints will seal properly in any axial position from fully homed to fully extended, and with any joint deflection angles up to the maximum rating.
**The working pressure is AMERICAN's suggested standard water working pressure. Contact AMERICAN if higher working pressure is involved.
***Thicknesses correspond to Special Class 56. Check AMERICAN if pipe with other wall thickness is required.
+Does not include lining weight. Underwater pipe weights are for fresh water. Sea water is approximately 3% heavier than fresh water, and these weights should be adjusted accordingly for sea water installation.
++When full of air, pipe of this thickness will float unless weight is added. See Table No. 11-1 for cement-lining weights. Gross weight, including pipe, gland and lining, is painted on each length of Flex-Lok pipe to aid in field calculations of actual buoyancy.
Flex-Lok Ball ends may be integrally cast or threaded-on, our option.

ADIP Table No. 10-3

Notes:
*Refer to Table No. 10-1 for thickness "T" dimensions.
+Check AMERICAN for greater end pull requirements.

ADIP Table No. 10-5

Notes:
*The maximum laying length (and accordingly the maximum overall length) is subject to trim pipe allowance in accordance with AWWA C151; also, this is the fully homed or inserted laying length of 4"-24" Flex-Lok pipe. In installations where 4"-24" joints are pulled or extended to metal-binding contact of joint locking members, some slight additional laying length will be gained as a function of the removal of joint assembly space. The joints will seal properly in any axial position from fully homed to fully extended, and with any joint deflection angles up to the maximum rating.
**Overall Length (O.L.) equals Laying Length L.L. + A + B.
Flex-Lok Ball ends may be integrally cast or threaded-on, our option.

ADIP Table No. 10-5 Part B Flex-Lok...

Notes:
***These lengths are generally applicable for 4"-24" Flex-Lok pipes. In pipe sizes greater than 12", AMERICAN may have capabilities to produce longer lengths. See Table 10-7 for similar 30"-54" configuration lengths, and please contact AMERICAN for specific longer lengths if desired.
Use formulas to obtain Overall Length corresponding to Maximum Laying Length or to any other required Laying Length.
Other joint combinations are available with Flex-Lok pipe, including Flex-Lok Ball and Ball in certain sizes. Check AMERICAN for further details on any desired combination.

ADIP Table No. 10-8

Notes:
Flex-Lok Connecting Pieces can be used to effect a change in direction in the shortest distance. They are used in lieu of Flex-Lok Bends.
*Thicknesses correspond to Special Class 56.
**Laying Lengths represent the minimum Laying Lengths of Flex-Lok Ball Joint Pipe.

ADIP Table No. 10-10

Notes:
*Laying Lengths shown exclude the bolted-on pulling flange.
Pulling flange contains 2 taps (1" taps for 4"-10" and 2" taps for 12"-54").
Flex-Lok Closure Assemblies are available on loan basis for use in installing lines by pulling and for testing of lines after installation. They are normally furnished in pairs, i.e., one Ball and Closed End Assembly and one Socket and Closed End Assembly.
Assembled weights include the bolted-on pulling flange.
