Installation
Note
It is very helpful to have two welders welding the assemblies to pipe, with one welder starting
180° from the other. This helps prevent movement of the fittings during the temperature
changes associated with welding.
d. Check the alignment after the first pass. Remove the alignment bar and weld the
next pass. Recheck alignment.
e. Continue applying weld passes and rechecking alignment until welding is complete.
The fillet welds will be approximately 1
1
/8-in. (29 mm).
3. Weld the opposite side weldolet to the pipe.
a. Slide the alignment bar through mounting and hole in top side of pipe and place the
opposite-side support weldolet over the end of the alignment bar.
b. Visually center the opposite-side weldolet over the hole. Tack weld the weldolet,
using tack bars or an equivalent method.
c. Weld the first pass and check alignment using the alignment bar and continue
welding. Check alignment frequently during welding. Adjust weldolet as you are
making tacks to keep aligned. Do not leave alignment bar in too long as it will heat
up and make it very difficult to remove.
d. When welding is complete, the alignment bar should slide freely through the
packing into the opposite-side weldolet.
e. Weld opposite end cap to weldolet using a full penetration groove weld.
4. Perform required heat treatment.
5. Reinstall 585 Main Steam Annubar sensor after heat treating and ensure the flow arrow
is pointing in the direction of flow.
Step 4: Insert the Annubar sensor
1. Place the packing into the packing gland with the two split rings (Garlock style
1303FEP) on the outside and the three Garlock Carbon/Graphite solid die-formed rings
on the inside. Make sure the splits in the outer packing are 180° apart.
Note
The packing gland and support plate will be shipped fully assembled.
2. Slide the 585 Annubar sensor through the packing and install the locking rods, nuts,
and lock washers. The dimension between the plates should be 11.0-in. (279 mm). See
Figure 2-38 on page 58. If there is visual access to the inside of the pipe, ensure that the
sensing holes are equally spaced from the inner diameter of the pipe.
3. Make the small adjustment (if necessary), then lock the 585 in place with the locking
rods, nuts, and lock washers. When installed, the 585 will have a dimension of 29.6-in.
(752 mm) from pipe OD to top of head.
4. The last thing to be done is to tighten the packing gland nuts to 25 to 30 ft-lbs. (34 to
41 N-m). See Figure 2-36.
