Specifications
1. All parts listed are designed for (-1 Bar g) (full vacuum)
and have a maximum test at (-0.9 Bar g) due to facility
altitude and equipment limitations.
2. Maximum operating temperature of 121°C for EPDM,
butyl and Viton ® ; 107°C for Neoprene; 99°C for nitrile;
82°C for pure gum rubber; 149°C for EPDM and butyl
in air services at (1.7 Bar g) maximum; higher pressure
and temperature ratings available.
3. All sizes can be supplied with a filled arch reducing
their movements by 50% and increasing the spring
rates fourfold. Expansion joints with ANSI/AWWA
flanges have lengths (F/F) in nominal inch conversions
unless otherwise agreed.
4. For full product specifications and installation
instructions, see SPEC 1101CR/ER and ININ
1101CR/ER.
5. WARNING: Control units (sold separately) must be
used when piping is not properly anchored. Number of
rods is dependent upon maximum field test pressures.
Expansion joints may operate in pipelines carrying
fluids at elevated temperatures and pressures, so
precautions should be taken to ensure proper
installation and regular inspection. Care is required to
protect personnel in the event of leakage or splash.
Adequate floor drains are always recommended.
6. Movements are non-concurrent. Contact PosiFlex for
concurrent movements, and for sizes not shown up to
3600mm DN.
7. Contact PosiFlex for full details including availability of
larger sizes, higher pressure and temperature ratings,
as well as additional arches.
All sizes are designed for (-0.5 Bar g) vacuum, full
vacuum (-1 Bar g) designs available.
8. Gross weights include retaining rings.
