Cell Corrosion
Test fluids under high tempreature and pressure can corrode the cell body
and caps. Carefully inspect the cell body and calls for corrosion before and
after each test.
Some materials are more susceptible to corrosion than other. Also, some
fluids and additives are more corrosive than others. OFITE offers a variety of
cell materials for different levels of corrosion resistance and cost.
Regulator Safety
The OFITE 175 mL HTHP Filter Press uses two regulators as standard equip-
ment. Both may be operated with Carbon Dioxide (CO
2
) or Nitrogen (N
2
) gas.
1.
Concoa Regulator 8051140-00-1: Top or Main Pressure.
a.
Maximum Inlet Pressure – 3,000 psi
b.
¼” NPT Connections
c. Single stage regulator
2.
Concoa Regulator 8051179-00-1: Bottom or Back Pressure.
a.
Maximum inlet pressure – 2,500 psi
b.
¼ “ NPT Connections
c. Single stage regulator
3. Never subject the regulator to inlet pressure greater than its rated inlet
pressure as shown on the regulator body.
4.
Do not allow oil, oil bearing materials, grease, or other combustibles to
contaminate the inside or outside of the regulator, especially where Oxy
-
gen is in use.
5.
To minimize heat effects, avoid the use of piping or tubing between the
pressurized cylinder and the regulator. If unavoidable it should be as short
as practical and equipped with a shutoff valve located just before the
regulator.
6. The 8051140 regulator has been internally cleaned for Oxygen but it is
not recommended to pressurize HTHP Filtration tests with Oxygen due to
its potentially explosive nature.
7.
Never pressurize a regulator that has loose or damaged parts or is in
questionable condition. Never loosen a connection or attempt to remove a
part until gas pressure has been relieved.
8.
Before transporting pressurized cylinders that are not secured on a cart
designed for such transport, remove all regulators and recap the cylinders.
