Common questions on this part
Double sphere joints feature two arches, providing double the axial movement, lateral deflection, and vibration absorption capacity of single sphere joints.
It is rated for a continuous working pressure of 16 Bar (PN16 / 232 PSI) with a burst rating of 48 Bar.
Yes, EPDM is superior for hot water, steam condensate, and weak acids up to 110°C.
Yes, the floating steel flanges rotate 360 degrees around the rubber lip, making bolt-hole alignment effortless.
Control rods are recommended when pipework is unanchored or operating near maximum pressure to prevent excessive elongation.
The face-to-face length of the 2" double sphere joint is 175 mm.
Yes, STARNEX stocks 2" double sphere expansion joints at our Nairobi branch.
Yes, it is vacuum rated up to 700 mmHg.
Standard PN16 / BS4504 4-bolt drilling pattern for 2" (DN50) pipe.
For diesel and oil lines, NBR (Nitrile) rubber joints are recommended instead of EPDM.
