Spray Shields
Warning: Expansion joints may operate in pipelines or equipment carrying fluids and/or gases at elevated temperatures and pressures. Normal precautions should be taken to make sure these parts are installed correctly and inspected regularly.
Precautions should be taken to protect personnel in the event of leakage or splash. Note: Piping must be properly aligned and anchored to prevent damage to an expansion joint. Movement must not exceed specified ratings and control units are always
recommended to prevent damage in the event other anchoring in the system fails. Properties applications shown throughout this data sheet are typical. This information does not constitute a warranty or representation and we assume no legal
responsibility or obligation with respect thereto and the use to which such information may be put. Your specific application should not be undertaken without independent study and evaluation for suitability.

When under pressure, a longer bellows will react the same
as a column when subjected to compression. At some point
both will buckle or "squirm". PROCO can offer a solution to
prevent this squirming effect during operation or testing.
Squirm can cause a catastrophic failure of the expansion
joint, and serious thought must be given to this condition at
time of system engineering. If desired,
PROCO can offer a design that will
eliminate the squirming effect . Once
manufactured, a hydrostatic test of the
joint provides assurance that it will hold
its form under pressure. If a hydrostatic
test is required, it should be specified
at the time of quotation. STABLE
