Ductile Iron Universal Coupling for Pipe
Features
Ductile iron coupling is a type of cast iron pipe coupling used to connect two pipes. It can connect pipes of the same material or pipes of different materials. It can connect pipes of the same size or pipes of different sizes. Flexible pipe coupling are used to connect pipes made of materials such as ductile iron, steel, PVC, AC, GRP, etc.
Main functions: Pipeline maintenance, connecting pipes of different materials or sizes, aligning pipes, changing pipe direction, absorbing vibration, adapting to slight misalignment, allowing for thermal expansion and contraction of pipes.
Application: Widely used in drinking water systems, neutral liquid transportation, sewage treatment, industrial pipelines, agricultural irrigation, etc.
Product Features:
● Wide range tolerance on O.D. (up to 24mm)
● For different materials or outside diameters
● Put the pipe’s major sizes within the most reasonable positions
● The gasket is at the perfect situation after assembled
● Reduced risk of leakage when the pipe OD at the minimum range
● FBE coating according to BS 6920-1
