1.) The laying lengths in the above tables are subject to trim pipe allowance in accordance with AWWA C151. Also, this is the fully homed or inserted laying length of 4”–48” Flex–Lok Pipe. In installations where 4”–48” 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.
2.) The working pressure is AMERICAN’s suggested standard water working pressure. Contact AMERICAN if higher working pressure is involved.
3.) Thicknesses correspond to Special Class 56. Check AMERICAN if pipe with other wall thickness is required.
4.) 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.
5.) When full of air, pipe of this thickness will float unless weight is added. See Standard 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.
6.) Contact AMERICAN on requirements for 64” Flex–Lok.
7.) 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.
8.) Thicknesses correspond to Special Class 56 for 24”–54” sizes. Contact AMERICAN if pipe with other wall thickness is required.
9.) Contact AMERICAN for greater end pull requirements.
10.) The full deflection and laying length of 24”–54” joints is most readily obtained by fully extending the joints.
11.) 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 Flex–Lok pipe. In installations where 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.
12.) Overall Length (O.L.) equals Laying Length L.L. + A + B.
