Unrestrained section of the pipeline is pipeline which is free to displace axially or flex
at bends. Unrestrained section may include aboveground pipeline that is configured to
accommodate thermal expansion or anchor movement through the flexibility, bends and
adjacent pipeline buried in soft or unconsolidated soil, and unbackfilled section of

adequate space is available. Elastic bend loads will produce bending stress to the
pipeline. The longitudinal and combined stress of the pipeline which is subject to the
elastic bend loads shall not exceed the limits shown in the Table 6.5

6.6 MOTHER PIPE THICKNESS CALCULATION

The minimum bending radius allowable for Hot bend is 5D, where D is the nominal outer
diameter of pipe.
The wall thickness of finished bend shall take into account wall thinning at the outer
radius and will be greater than design thickness.
Wall thinning percentage of mother pipe wall thickness is computed with formula
indicated in BS PD 8010-1 para. 6.2.2.3.
50%
t thin = = 0.09
(n + 1)
where
t thin = wall thinning, as a percentage (%)
n = inner bend radius divided by pipe diameter
(5D−0.5D)
n= = 4.5

t Bend =
(1 − t Thin1h )
Where
t w = nominal wall thickness selected for linepipe (mm)
Note: The above formula does not consider other factors that depend on the bending
process and the bend manufacturer shall be consulted where wall thinning is critical.
6.7 FREE END EXPANSION AND ANCHOR LOADS

Pipeline movement shall occur due to high temperature and pressure. Pipeline systems
shall have sufficient flexibility to allow for pipe thermal expansion.
Where the anchors are not available in the pipeline, the transition zone and aboveground
portion will be expanded due to thermal load. Aboveground pipe that is configured to
accommodate thermal expansion. The above-ground pipelines shall be routed in a
manner such that no excessive movement occurs on the pipes due to the effects of
thermal expansion and / or contraction, internal pressure and other design internal or
external loads. Pipeline end expansion in the transition zone between above ground and
underground shall be limited to 50mm and verify by stress analysis, to maintain this limit,
including adding flexibility provisions in aboveground and underground, increasing burial
depth and/or providing anchor blocks.
6.8 PIPELINE BUOYANCY

The requirement for stability of the pipelines in areas susceptible to soil liquefaction will
be investigated where there is a need and subsequent mitigation measures will be
investigated and employed.
The pipeline to be laid in a trench covered by soil, which will provide a hold down force
to prevent buoyancy. Depending on the buoyancy requirement, suitable buoyancy
preventive method (such as concrete coating or any other option) shall be applied. This
force is calculated by determining the submerged weight of soil above the pipeline.
The method used to determine the vertical stability of the pipeline is to calculate the
total weight of the pipeline, the soil hold down force and compare them with the weight
of the external fluid (water) the pipeline would displace.

6.9 ABOVE GROUND EXPANSION LOOP

Flexibility of above ground pipeline shall be obtained through pipe routing or expansion
loops. Expansion loops, provided, shall clear adjacent pipeline and can be 2 Dimensional
or 3 Dimensional based on process requirements and layout feasibility.
Expansion loops shall be provided as per Stress Reports for 10" LP Trunklines (Doc. No.
17051820-0032-C1-060-STA-0001 to 0009) and Typical drawing for Expansion loop &
