Def: 2) An existing pipeline to a pipeline under construction.

3) A pipeline to an anchor.
4) Pipeline sections to an intermediate mainline valve
that is being inserted.
A General Requirements
One of the following provisions must be in place prior to welding of
temperature tie-in joint:
1) Anchor is installed on the end of pipeline upstream of the welding

A5
rain or when the welders are exposed to inclement conditions. Para. 10.2.2

SAES-W-012
A6 arc stability or shielding gas coverage, or when deemed necessary by
Para. 10.2.1
Saudi Aramco Inspection.
Welding surface is clean and free from oil, moisture, rust, scale, sand,
SAES-W-012
A7 paint, metallic coatings or other foreign matter, at least 25 mm from the
Para. 10.3.1
area of interest prior to welding.
Protective sleeves are wrapped snugly around the coated ends of the SAES-H-200
A8
pipes adjacent to the girth weld area. Para 6.2.1

A9
complete prior to removal of the external clamp. Para. 10.4.2
At least two welders are used for pipelines greater than 16 inch diameter, SAES-W-012
A10

The Construction Engineer has determine the highest practical tie-in
temperature for each tie-in weld.
*NOTE: The tie-in temperature shall be within the range stated in the
SAES-L-450
A12 Project Specifications.
Para. 15.2
**NOTE: Indicate the following:
a. Project specified Tie-In Temperature Range: __________
b. Highest practical Tie-In Temp: __________
The measured tie-in temperature is within the project specified tie-in
temperature range. ( Tie-In Temp=____________)
*NOTES:a) Contact measuring device shall be shielded from direct SAES-L-450
A13
sunlight to prevent an inaccurate reading. Para. 15.3
b) Actual tie-in temperature is the average of two readings, one at the
top and one at the bottom of the pipe.
The actual tie-in temperature and the pipeline stations of the tie-ins are SAES-L-450
A14
recorded in the inspection record books. Para. 15.4
The hot pass is made while the pipe is still fully supported by the SAES-W-012
A15
sideboom tractor or supports. Para. 10.7.3
SAES-L-450
A16 Temperature tie-in welds are kept free of movement to prevent cracks.
Para. 15.5.1
During the night and the cool periods of the day, there should be at least
SAES-L-450
A17 900 m to 1200 m of pipe outside the trench to keep the S-curve in
Para. 15.5.2
sufficient tension to restrain the pipe already in the trench.
B Aboveground Non-restrained Pipelines:
A string is always connected to each side of the anchor stub when the SAES-L-450
B1
work is stopped at the end of the day. Para. 15.8
C Buried Pipelines:
When a sufficient number of strings have been completed, the first string
SAES-L-450
C1 of a buried pipeline shall be placed in the trench and spot backfilled (or
Para. 15.5.1
tied into an anchor) during the hottest part of the day.
SAES-L-450
C2 The subsequent strings shall be connected by temperature tie-in welds.
Para. 15.5.1
Each new string must be kept free of movement to prevent cracks in the SAES-L-450
C3
tie-in weld. Para. 15.5.1
The portion of the pipeline outside the trench shall be supported by side SAES-L-450
C4
booms holding the line in a gentle S-curve. Para. 15.5.2
Spot backfilling (used to anchor to the line) may be completed at any SAES-L-450
C5
temperature but no closer than 1200 m from the free end of the tail. Para. 15.5.4
If spot backfilling closer to the free end is required, it shall be done SAES-L-450
C6
during the hottest part of the day. Para. 15.5.4

If the tie-in weld is made with the pipe in the trench (at tie-in temperature)
the string being tied in and the tail must be spot backfilled on the same
SAES-L-450
C7 day of the tie-in.
Para. 15.5.5
* NOTE: The spot backfilling shall not be closer than 24 meters from the
free end.
D Aboveground Restrained Lines:
When a sufficient number of strings have been completed, the starting
SAES-L-450
D1 end of the pipeline is tied-in to a full thrust anchor or to a minimum of 600
Para. 15.6.1
meters of buried pipeline using a temperature tie-in.
The strings which have been tied-in while resting on the skids or on the
SAES-L-450
D2 sand, are placed onto the supports by side booms, holding the line in a
Para. 15.6.2
gentle S-curve between supports and skids.
The pipeline that has been placed onto the supports has the top halves
SAES-L-450
D3 of ring girder supports or support straps, bolted in place on the same day
Para. 15.6.2
it is placed.
There shall always be at least 900 m to 1200 m of pipe attached to the
SAES-L-450
D4 line on skids or on the ground, to restrain it during the night and cool
Para. 15.6.3
periods of the day.
The pipeline strings may also be welded while resting on permanent
SAES-L-450
D5 supports, but only if the supports are designed to resist the friction forces
Para. 15.6.4
of the line developed under full temperature differential.
Two strings on supports may be tied together with a temperature tie-in
weld. This 1800 m to 2400 m double string may then be tied in to the
SAES-L-450
D6 pipeline at normal daily temperatures. However, the pipeline being tied
Para. 15.6.5
into must have an end anchor or be buried in order to obtain the highest
possible effective tie-in temperature.
