*8-1. The above hole sizes are for reference. The inner strainer installed in PHE mainly for marine use(sea water use) may
differ from the above hole sizes in consideration of cleaning frequency.
P9

(3)

Install support with sufficient strength for the piping connected to each nozzle. However, do not install fixed piping or
piping support inside the maintenance space.

(4)

The maximum allowable flow velocity for PHE port holes is 7 m/s, limited to fluids that are not corrosive or erosive.
In case piping with the same diameter as PHE port hole is used, erosion may occur on the inside surface of the piping
because the flow velocity in PHE is applied faster than in piping in general.
Please install a reducer appropriately to connect to PHE, after design of piping size for an appropriate flow velocity.

(5)

Arrange three or more short piping to be connected to each nozzle in order to remove each pipe.
In general, the nozzle stud bolts cannot be removed, so plan to remove the second short pipe and thereafter.

(6)

Use an expansion joint for the nozzle of C-Frame or E-Frame, since such
PHE may be tightened to MIN dimensions.

(7)

When using ring gaskets or spiral wound gaskets on the market, check the"Assembly Drawing" first and purchase the gaskets with specified external
dimensions in order to avoid interference between stud bolts and gaskets.

(8)

Be sure to fill steam from the upper nozzles (S1, S2, E1, E2, C1, C2)(*8-2).
Use the lower nozzles (S3, S4, E3, E4, C3, C4) as inlets for fluids that contain large amounts of debris or foreignmaterial, such as sea water.
*8-2. DXC-650 : As per drawing instructions.

(9)

Install air vent valve on the piping connected to the upper nozzles (S1, S2, E1, E2, C1, C2), and drain valve on piping
connected to the lower nozzles (S3, S4, E3, E4, C3, C4).

(10) Arrange the piping enough to drain out when using saturated steam.
Do not arrange the outlet piping over the height equal to steam head pressure.

(11) In case of upward piping, drawdown will occur during maintenance, so install a foot valve and a feeding line.
(12) Drain out completely to avoid freezing in case of preservation for long term in cold areas.
(13) Install safety apparatus compliant with various standards or regulations to theNozzle for leak detection

piping you connect.
(14) If PHE model is NX-30/NX-50, nozzles for leak detection are installed andE-Framekept open.

P10

8-2

Before Piping(1)

When the pipe attached to the E frame side of the heat exchanger is designed, please design it to correspond to bothmaximum and minimums of tightening length.

(2)After referring to the Assembly Drawing, check below points;
1) Piping to be connected and the fluid are correct.
If the left and right nozzles are made of different materials, the piping connections cannot be switched between left
and right.
2) Inlet and outlet ports are correct.
Do not connect the steam inlet to a lower nozzle.

(3)

Curing seal, plywood, or iron sheet are installed on each PHE nozzle for shipping.
Remove them before connecting piping.

8-3

(4)

Check that there is no debris inside PHE nozzles and the piping to be connected.

(5)Check that the ratchet spanner or automatic tightening device does not contact with the piping and/or insulation.

Storage/Preservation
Follow the below cautions when PHE is stored a long term until the operation.
[CAUTION]: Do NOT remain a liquid in PHE.


To prevent clogging and corrosion in PHE chambers due to foreign material or dirt.



To prevent volume expansion or freezing in PHE chambers.

[CAUTION]: Cover PHE with a protective sheet to shade a light.

10

To protect PHE from impact or damage caused by external factors.

To protect PHE from dirt and dust.
