00:00:03:22 00:00:05:21
Coating pipeline welds in the field
00:00:05:22 00:00:07:15
faces many challenges, like
00:00:07:16 00:00:09:13
difficult site access, variable
00:00:09:14 00:00:11:08
weather conditions and the need for
00:00:11:09 00:00:13:10
optimal materials.
00:00:13:11 00:00:14:21
Cold temperatures make this even
00:00:14:22 00:00:16:21
harder, requiring pipes be heated
00:00:16:22 00:00:19:03
and environments be contained.
00:00:19:04 00:00:20:23
Traditional coatings require high
00:00:20:24 00:00:22:24
heat, making the application process
00:00:23:00 00:00:24:07
inefficient.
00:00:24:08 00:00:26:08
Liquid applications need preheating
00:00:26:09 00:00:28:11
and a heated cure to bond properly,
00:00:28:12 00:00:30:12
while powdered fusion bonded epoxies
00:00:30:13 00:00:32:10
cure almost instantly for quicker
00:00:32:11 00:00:34:11
inspections and backfilling.
00:00:34:12 00:00:36:02
When Keymay Industries faced
00:00:36:03 00:00:37:23
inefficiencies with powdered fusion
00:00:37:24 00:00:40:09
bonded epoxies in extreme cold,
00:00:40:10 00:00:41:20
they turn to Sherwin-Williams
00:00:41:21 00:00:43:03
Protective and Marine for a
00:00:43:04 00:00:44:14
solution.
00:00:44:15 00:00:45:14
The result Pipeclad
00:00:46:17 00:00:48:17
2000 LAT an
00:00:48:18 00:00:50:02
innovative low application
00:00:50:03 00:00:51:19
temperature coating that requires
00:00:51:20 00:00:53:12
less heat, reducing costs and
00:00:53:13 00:00:55:01
emissions while increasing
00:00:55:02 00:00:56:12
efficiency.
00:00:56:13 00:00:58:08
We moved over to the
00:00:58:09 00:00:59:08
Pipeclad 2000 LAT
00:01:00:12 00:01:02:04
low application temperature fusion
00:01:02:05 00:01:04:20
bond in 2020,
00:01:04:21 00:01:06:19
and it was a complete
00:01:06:20 00:01:09:07
game changer for us, especially
00:01:09:08 00:01:10:17
up here in the winter times.
00:01:11:23 00:01:13:13
The process begins with surface
00:01:13:14 00:01:14:13
preparation. An induction
00:01:15:10 00:01:16:23
heat coil brings the weld to the
00:01:16:24 00:01:18:15
correct temperature.
00:01:18:16 00:01:20:12
The automated applicator then sprays
00:01:20:13 00:01:22:12
the fusion bonded epoxy powder,
00:01:22:13 00:01:24:12
which melts and flows instantly
00:01:24:13 00:01:26:06
forming a durable, monolithic
00:01:26:07 00:01:27:08
barrier.
00:01:27:09 00:01:29:18
For application of this system.
00:01:29:19 00:01:33:05
With the Pipeclad 2000,
00:01:33:06 00:01:35:07
we get a lot more joints.
00:01:35:08 00:01:36:05
Quite a few more joints in a day
00:01:36:06 00:01:38:06
done, were not heating
00:01:38:07 00:01:40:02
as high for everyone, so
00:01:40:03 00:01:41:12
it definitely speeds everything up
00:01:41:13 00:01:42:17
that way.
00:01:42:18 00:01:44:18
And like I say, less time
00:01:44:19 00:01:46:16
on the joints the more you get
00:01:46:17 00:01:48:15
done. So it really
00:01:48:16 00:01:49:15
has helped that way.
00:01:51:09 00:01:53:16
Pipeclad 2000 LAT has transformed
00:01:53:17 00:01:55:21
Keymay operations, especially
00:01:55:22 00:01:57:02
in colder conditions.
00:01:58:06 00:01:59:20
The reduced heating requirements
00:01:59:21 00:02:01:19
have significantly cut down on costs
00:02:01:20 00:02:04:06
and improved their efficiency.
00:02:04:07 00:02:05:21
With low application temperature
00:02:05:22 00:02:07:10
fusion bonded epoxies.
00:02:07:11 00:02:09:05
The lower heat requirement mitigates
00:02:09:06 00:02:11:06
risks such as burning or blistering
00:02:11:07 00:02:12:19
pre-applied coatings and
00:02:12:20 00:02:14:17
condensation interference,
00:02:14:18 00:02:16:16
translating to fewer repairs and
00:02:16:17 00:02:18:17
faster project timelines.
00:02:18:18 00:02:20:24
It is a very seamless application.
00:02:22:00 00:02:23:21
It's pretty much perfect
00:02:23:22 00:02:25:06
every single time.
00:02:25:07 00:02:27:02
We've consistently held
00:02:27:03 00:02:29:12
a less than 1% repair rate.
00:02:29:13 00:02:31:11
The automated application process
00:02:31:12 00:02:33:09
is a game changer.
00:02:33:10 00:02:35:13
A repair rate of less than 1%
00:02:35:14 00:02:37:03
is a testament to the quality and
00:02:37:04 00:02:39:14
consistency of Pipeclad 2000
00:02:39:15 00:02:40:14
LAT.
00:02:40:24 00:02:42:05
When looking at the application
00:02:42:06 00:02:44:03
process, when you go from blasting
00:02:44:04 00:02:45:17
to induction heating to the
00:02:45:18 00:02:47:12
application of the powder
00:02:47:13 00:02:49:19
Keymay proprietary auto bond,
00:02:49:20 00:02:51:00
automated system works
00:02:51:01 00:02:52:16
synergistically with
00:02:52:17 00:02:54:05
Sherwin-Williams, low application
00:02:54:06 00:02:56:02
temperature fusion molded epoxy.
00:02:56:03 00:02:57:17
And in doing so, they're able to
00:02:57:18 00:02:59:02
speed up the installation of the
00:02:59:03 00:03:00:23
pipeline, thus saving money in
00:03:00:24 00:03:03:06
installation and time is money.
00:03:03:07 00:03:04:25
And this system and this process
00:03:04:26 00:03:05:25
saves both.
00:03:07:00 00:03:09:00
Keymay has coated over 50,000
00:03:09:01 00:03:11:02
girth welds with Pipeclad 2000
00:03:11:03 00:03:13:01
LAT, achieving a repair
00:03:13:02 00:03:15:08
rate of less than 1%.
00:03:15:09 00:03:17:04
The Key Access Pipeline System
00:03:17:05 00:03:19:07
project highlighted this efficiency
00:03:19:08 00:03:21:10
even in winter conditions.
00:03:21:11 00:03:22:19
It still carries the same
00:03:24:09 00:03:26:06
environmental benefits as
00:03:26:07 00:03:28:05
the regular fusion bond, you're not
00:03:29:13 00:03:31:04
getting extra coating kits and
00:03:31:05 00:03:32:09
coating consumables.
00:03:32:10 00:03:34:02
It's very clean where vacuum
00:03:34:03 00:03:35:19
collected.
00:03:35:20 00:03:37:10
The environmental benefits of these
00:03:37:11 00:03:39:11
chemistries cannot be overstated.
00:03:40:13 00:03:42:15
By producing less waste and reducing
00:03:42:16 00:03:43:13
emissions.
00:03:43:14 00:03:45:19
Pipeclad 2000 LAT aligns
00:03:45:20 00:03:47:12
perfectly with the sustainability
00:03:47:13 00:03:48:13
goals held by Keymay.
00:03:50:01 00:03:51:05
Sherwin-Williams.
00:03:51:06 00:03:53:12
Innovating for a Sustainable Future.
