NINGHAO Machinery offers the Carbon Steel Flanged Connection Single Ball Rubber Expansion Joint.
This joint meets strict design parameters.
The product comes in many sizes.
DN values range from 1 1/4 inch to 24 inch.
DN is given in inches and millimeters.
The joint has a set length.
L values range from 95 mm to 265 mm.
D values range from 140 mm to 840 mm.
Ø values range from 100 mm to 770 mm.
Reinforcement details vary by size.
N-ØH values change from 4×18 to 20×36.
This setup aids joint performance.
