WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Non-Fulton product information is for
reference purposes only. No Fulton
document may substitute for full
review of documentation available
from the component manufacturer.
10. Provide properly designed supports and anchors for all piping where
necessary to prevent undue stress from being imparted on equipment
such as pumps, valves and the heater. Care should be taken as end
reactions transmitted to rotating equipment, such as pumps, may deform
the equipment. Therefore equipment manufacturers’ recommendations
on allowable forces and movements should be followed. Ensure all pipe
joints are of either welded or fl anged construction. Screwed joints must be
avoided where possible. In no instance should screwed joints be used in
the fl ow circuit. All fl anges should be welded to the pipe and not screwed.
Depending on the size, fl anges should be 150# or 300# raised face fl anges,
SA105.
11. Ensure heaters that are skid mounted with pumps and tanks are equipped
with a y-strainer, a fl ex connector and a valve in the inlet run between the
pump and the combination tank. Piping between the discharge of the
pump and the inlet of the heater will include a fl ex connector and a valve.
12. If screwed connections have to be made, e.g., to items of control
equipment, use a thread sealant suitable for use with fl uids at elevated
temperature. Tefl on tape, standard pipe sealant, or hemp and paste are not
acceptable.
13. Cut screw threads carefully and accurately. If possible, new tools should
be used. Threaded connections larger than 1” are not to be used. It is
recommended that GR5 or higher tensile steel bolts be used for all fl anged
joints.
14. Use gaskets to make all fl anged connections. Gasketing material must be
suitable for use with the pressure, temperatures and fl uids in the system.
Flexible graphite gaskets are suited for most applications. Recommended
gasket thickness is 1/10 - 1/8 inch. Ensure that all bolts are tightened
evenly and to the torque recommended values provided by the gasket
manufacturer. Refer to Tables 5 - 8 and Figure 8 for guidelines.
NOTE:

Typical gaskets used by Fulton include JM Clipper Elastograph gaskets and
Flexitallic gaskets. Adhere to installation instructions and torque requirements for
these gaskets.
15. Install high point bleeds at all high points in the system piping. 1/2” x 12”
nipples welded in the top of the piping with ball valves and plugs attached
are to be used.
NOTE:  It will save a considerable amount of time during the cold fi ltration if the
system piping is cleaned prior to assembly. The mill scale (the results of oxidation)
on the inside of the piping as well as construction debris can foul the fl uid and
cause the need for the fi lters (strainers) to be cleaned more than need be. This can
range from simply using a rag to ordering pickled pipe. (“Pickling” is a process
where the piping is fi rst soaked in an acid bath, then soaked in a neutralizing bath,
then given a protective oil coating.)
16. Install all pipes with a pitch to facilitate draining and venting.
