Abstract:
Need:
There are two primary concerns with welding onto in-service
pipelines. The first is for welder safety during welding,
since there is a risk of the welding arc causing the pipe
wall to be penetrated allowing the contents to escape. The
second concern is for the integrity of the pipeline following
welding, since welds made in-service cool at an accelerated
rate as the result of the ability of the flowing contents
to remove heat from the pipe wall. These welds, therefore,
are likely to have hard heat-affected zones (HAZ) and a subsequent
susceptibility to hydrogen cracking.
Benefit: This manual describes the use of
the PRCI Thermal Analysis Model for Hot Tap Welding - V4.1,
which was developed by Edison Welding Institute (EWI) for
PRCI. The model is intended to provide welding engineers
with guidance for establishing safe parameters for welding
onto in-service pipelines (hot-tap welding).
Result: The model allows burnthrough risk
to be controlled by limiting inside surface temperature
and hydrogen cracking risk to be controlled by limiting
weld cooling rates.
Price:
The current
Thermal Analysis Model is available only on a lease basis.
The current pricing is as follows:
- For existing
customers of the software, it is available on a $995.00
per year basis, minimum three-year lease (one license).
- For first time
customers the software is available for $1495.00 for the
first year and $995 per year thereafter, for a minimum three
year lease (one license).
- The software
is also available on an unlimited site license lease of
$5000.00 per year also based on a three-year minimum lease.
