series 242 twin sphere expansion joints
Installation Note:
Install at the neutral length dimension as shown in Tables 2 & 3. Make
sure the mating flanges are FLAT-FACE TYPE. When attaching beaded
end flanged expansion joints to raised face flanges, the use of ring
gaskets are required to prevent metal flange faces from cutting rubber
bead during installation. Care must be taken when pushing the joint
into the breech between the mating flanges so as not to roll the
leading edge of the joint out of its flange groove.
Precompression Note:
Joint must be precompressed approximately 1/8" to 3/16" in order to
obtain a correct installed face-to-face dimension.
NOTES: 1. "HA", "HB", and "HC" denote Heavy Weight Construction.
2. Movements stated are non-concurrent.
3. To determine End Thrust: Multiply Thrust Factor by Operating Pressure of System.
This is End Thrust in pounds.
4. Pressure rating is based on 170 °F operating temperature. The pressure rating is
reduced slightly at higher temperatures.
5. Pressures shown are maximum "operating pressure." Test pressure is 1.5
times "operating pressure." Burst pressure is approximately 4 times "operating pressure."
6. Vacuum rating is based on neutral installed length, without external load. Products
should not be installed "extended" on vacuum applications.
7. Style 240-AV/NN (Neoprene elastomer only) expansion joints 1.25" I.D. – 12.0" I.D. come with
tapped holes in lieu of drilled holes.
8. All expansion joints are furnished complete with flanges. Control units are
required on applications where movements could exceed rated capabilities.
Standard PROCO Style 242-A Expansion Joints shown in Bold Type are considered Standards
and inventoried in large quantities.
