Functions and Purpose:
●Installed in aboveground or underground water transmission pipelines.
●Absorbs and accommodates pipeline movements caused by the following conditions:
▶Ground subsidence or displacement induced by earthquakes
▶Thermal expansion and contraction, pipeline settlement, misalignment, or vibration
●Provides functions of axial expansion and contraction, angular deflection, lateral offset,
and pull-out resistance.
●Prevents pipeline rupture and leakage, ensuring safe and stable water conveyance.
Features of Ductile Iron Ball-Type Flexible Joints:
●Suitable for medium- and low-pressure applications, municipal works, and general
underground pipeline projects.
