American Cast Iron Pipe Company

Restrained Joint Pipe-Flex-Lok Ball Joint Pipe

Product Description

AMERICAN Flex-Lok® Pipe incorporates a very flexible ball-and-socket type joint for use in such installations as subaqueous pipeline construction. The provision for significant changes in alignment, with available joint deflections of 25° for sizes 4”-12” and 15° for sizes 14”-60” in any direction, and the rugged features of AMERICAN Flex-Lok Pipe make it especially adaptable to the most difficult installations. This rugged joint configuration has an excellent record of performance, and under some of the toughest installation conditions, it has provided long life and trouble-free service. Economy and dependability have been proven in many installations under widely varying conditions.

AMERICAN Flex-Lok Boltless Ball Joint Pipe — manufactured in 4”-60”1 sizes2 — is a rugged, boltless, flexible joint pipe designed and manufactured to assure the greatest economy in installation with maximum performance and reliability. This ductile iron pipe meets all applicable requirements of AWWA C151 and is designed to withstand severe installation and service conditions encountered in river crossings, treated wastewater outfall lines, water supply intakes, swamps, floodlands and rugged terrain where significant joint deflection may be required.

AMERICAN Flex-Lok Boltless Ball Joint Pipe provides variable deflection up to at least 15°, and the joint may be deflected to metal binding position at maximum deflection without harm to the pipe or joint components. This is a result of the unique design and functionality of the pipe and joint components. In sizes 4”-12”, the configuration incorporates the additional flexible restraint provided by AMERICAN’s Flex-Ring joint, which cumulatively results in greater joint deflection capabilities, up to 25°.
