Expansion Joint, Single Sphere VS Expansion Joint, Twin Sphere

1. Material Similarity:

Both flange material of expansion joint single sphere and twin sphere can be carbon steel stainless steel ,both rubber material can be Neoprene.EPDM,NBR.



2. Pressure Similarity:

Both pressure of expansion joint single sphere and twin sphere are Class150,PN10/16,JIS 10K/16K



3. Range of Applications Similarity:

Standard: DIN PN/PN16, ANSI 150LBS, JIS 10K/16K.



Size: 1 1/4-120 DN32-DN3000
