2.3.3
MAKE HIGH PRESSURE GAS SUPPLY CONNECTION
GPC1 requires a high pressure gas supply equal to or less than the maximum desired test
pressure. This is often supplied by a
DHI
gas booster.
If a
DHI
gas booster is being used for the high pressure gas supply, interconnections to
connect the booster output to the GPC1
SUPPLY port
are supplied with the booster. See
the booster Operation and Maintenance Manual for details on setting up the connection.
The high pressure gas supply is connected to the GPC1
SUPPLY port
. The
SUPPLY port
is a
DH500 female (DH500 is equivalent to AE F250C, HIP HF4, etc.). Before connecting a high
pressure supply, be sure that the
TEST INLET SET
regulator
is fully backed off and the
INLET
valve
is closed. (Do not apply the supply pressure before reading Sections 2.4.1 and 2.4.5).
Do not connect a gas supply greater than 110 MPa (16 000 psi) to the GPC1-16000
SUPPLY port. Do not connect a gas supply greater than 70 MPa (10 000 psi) to the
GPC1-10000 SUPPLY port.
Highly pressurized gas can be extremely hazardous. Before applying pressure to GPC1
and/or the system connected to it, be sure that all pressure vessels and connections are
rated for the pressure levels that will be applied and that all connections have been
properly tightened (see Section 2.4.5). Ensure that the GPC1 TEST INLET SET regulator
is fully backed off and the INLET valve is closed (see Section 2.4.1).
DH500 F fittings are delivered with disposable, orange, plastic dummy plugs installed. These
are NOT intended to hold high pressure. They should be removed and replaced with
appropriate fittings or stainless steel plugs before high pressure operation. Each dummy
plug carries a DH500 collar. Remove and retain the collar for use in connecting to the fitting.

MAKE HIGH PRESSURE GAS INTERCONNECTIONS
2.3.4.1
CONNECTING TO A DHI RPM OR PG7202 USING THE
STANDARD GPC1 INTERCONNECTIONS KIT
GPC1 is delivered with an interconnections kit (see Section 2.1.2, Table 1).
This kit includes the high pressure hardware necessary to connect GPC1 to a
DHI
RPM or PG7202 and operate at pressure up to 110 MPa (16 000 psi)
(limited to 70 MPa (10 000 psi) with GPC1-10000). See Figure 4 for the
recommended layout and to identify the parts used from the interconnection kit.
These setups assume that one (1) of the
TEST ports
on the top of GPC1 or an
open leg of the interconnecting tee will be used to connect to the device or
system under test. To convert a DH500 F to another fitting, install one (1) of the
DH500 F x 1/8 in. NPT M or DH500 F x 1/4 in. NPT F adaptors on to one of the
2.75 in. (70 mm) DH500 nipples and install the nipple into the DH500 F port.
If the reference device is a PG7202, it should always be connected to the left,
rear lateral
TEST2 port
.
