30''-60" Ball Joint Pipe

AMERICAN Ductile Iron Flex-Lok Boltless Ball Joint Pipe For Water, Sewage and Other Liquids 30"-60"

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. 10-2

Notes:
*Check AMERICAN on requirements for 64" and larger Flex-Lok.
**Laying length is subject to trim pipe allowance in accordance with AWWA C151; also, this is based on the fully extended or pulled-to-metal-locking position of 30"-60" Flex-Lok joints. In installations where 30"-60" joints are not pull-extended in the assembly procedure, the tabulated laying lengths will be reduced by approximately 2" per joint in 30"-54" sizes and 2-1/2" in the 60" size, which is the result of the non-removal of the joint assembly clearance space in the joints. 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 maximum rating when the joint is extended.
***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 for 30"-54" sizes and Pressure Class 350 for the 60" size. 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, ring and lining, is painted on each length of Flex-Lok pipe to aid in field calculations of actual buoyancy.

ADIP Table No. 10-4

Notes:
*Refer to Table No. 10-2 for thickness "T" dimensions.
**The full 15° rated deflection and laying length of 30"-54" joints is most readily obtained by fully extending the joints.
+Check AMERICAN for greater end pull requirements.
Check AMERICAN on requirements for 64" or larger Flex-Lok.

Notes:
Check AMERICAN on requirements for 60" and larger Flex-Lok.
*Laying length is subject to trim pipe allowance in accordance with AWWA C151; also, this is based on the fully extended or pulled-to-metal-locking position of 30"-60" Flex-Lok joints. In installations where 30"-60" joints are not pull-extended in the assembly procedure, the tabulated laying lengths will be reduced by approximately 2" per joint, which is the result of the non-removal of the joint assembly clearance space in the joints.

**Overall Length (O.L.) equals L.L. + A + B

ADIP Table No. 10-7

Notes:
Use formulas to obtain Overall Length corresponding to other required Laying Lengths.
Overall Length of Flex-Lok Socket and Flange/P.E. Pipe = L.L. + A
Overall Length of Flex-Lok Ball and Flange/P.E. Pipe = L.L. + B
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. 10-9

Notes:
*Thicknesses correspond to Special Class 56 in 30"-54" sizes and Pressure Class 350 in the 60" size.
**Laying Lengths represent the minimum Laying Lengths of Flex-Lok Ball Joint Pipe.
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.

ADIP Table No. 10-11

Notes:
*Laying Lengths shown exclude the bolted-on pulling flange.
**Check AMERICAN for the availability of a shorter closure piece if desired.
Pulling flange contains 2 taps (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.

†60" Flex-Lok Closure Assemblies are constructed differently from 30"-54", but with the same functionality (a pulling plug with taps is inserted in the bell or bell end, instead of a short length of flange pipe as pictured). Contact AMERICAN.
