Installation Practices
Good installation practice for all types of buried pipe of ten calls
for wrapping of the pipe to decrease corrosion due to soil con-
ductivity. Although stainless steel is less sus cep ti ble to corro-
sion, local codes and general practices should still be followed.
Field Test Procedures
Normal field test procedures call for a hydrostatic pres sure
test of the system prior to final acceptance. Often, seg ments
of the system will be tested individually prior to the complete
system test. In order to hydrostatically test the transition riser as
installed, two methods are rec om mend ed.
1. Constrained Piping
If the piping installation is essentially complete, the pip ing
restraints may adequately take the thrust loads gen er at ed by
having a blind end on the pipe system. In these cases, no
special actions to restrain thrust or side loads are required,
and the fitting installed in the system may be ad e quate for
hydrostatic testing.
2. Free Piping
If just the riser or riser/main connection is to be tested, then
the thrust loads from the blind end cap on the riser may need
to be restrained. The riser design has been test ed in the
unrestrained state using a rigid coupler and end cap grooved
fitting. Flange adapters, expansion fit tings, or other styles
of end connectors may result in ex ces sive end thrust which
may cause a leak or fitting mal func tion. In addition, couplings
which are adequately rat ed for high pressure testing should
be used if thrust re straints are not feasible.
NOTE: It is important that all air is bled from the system
be fore pres sur iz ing any component.
