The document discusses the 'lift-off' pipe supports developed by 500 Projects LLC, designed to mitigate issues like crevice corrosion and enhance fluid drainage in piping systems. It highlights the innovative design that increases the load area, reduces stress on coatings, and eliminates the need for hot work during installation. Additionally, the document provides technical specifications and information on testing, materials, and the company's global presence.

2. Crevice Corrosion and U-Bolt Combination
Paint damage caused by U-bolts.
Water not draining from support.

3. Atmospheric conditions support degradation
Cracks appearing on
support attachments
All these strips will
require replacement.

4. Badly corroded line with U-Bolts and wear strip
damage

5. Badly installed protection barrier, crevice corrosion is
not addressed.
Galvanic barrier pressed
out under line, many of
these tiles were lying on
the deck.

6. Stainless Steel line on Galvanized Steel Beam, galvanic
corrosion will ensue.
Wear Strip pressed out
under the line, this was
glued on with epoxy.

7. Trying to solve the mechanics of crevice corrosion has been one of the biggest engineering challenges for
decades. Failures have been catastrophic.
On and off-shore installation piping systems are nearing, or have exceeded their design life and in particular,
high corrosion areas such as pipe supports have contributed significantly to the failure of the system.
“Lift-Off” pipe support systems is developed to increase in piping system by reducing crevice corrosion in
piping systems.
The “Lift-Off” design is a “patented pipe support system” that increases fluid drainage, thereby reducing
corrosion and fluid hang-up or retention.
‘Lift-Off” also has the advantage of distributing the pipe load over a larger coated area, thereby reducing
stress on the coating. We estimate the average load area has been increased by a minimum of fourteen(14)
times.
Our range of products are available to the piping industry where ease of installation, corrosion mitigation as
well where hot work is a factor.

“Lift-Off” Pipe Supports
Overview

8. The Following simulations was done with
Solidworks® Flow Tool to study the flow pattern
of rainfall over a 4” NB “Lift-Off” Pipe support,
base.
Simulation parameters were as follows:
• A 4” nominal diameter XXS with a wall
thickness of 0.674 inch pipe was used.
• OD of Pipe is 4.5”.
• Pipe Material: Carbon Steel.
• Pipe support material: Stainless Steel 316.
• Rainfall velocity: 4m/sec or 12ft/sec.
• Turbulence Intensity: 2%.
• Turbulence length: 0.002m or 0.08”.
• Mesh Size: 64365

Cap screws are wired
together to prevent

15. Side Elevation
Support and pipe
can slide laterally
across beam.

16. Plan view
Line supported on beam, hold-
downs can also be added to stop line
from jumping off support in the
event of large pulsating events.

17. • “Lift-Off” product range can be manufactured from most carbon steels, including all alloys, carbon
composites, plastics and their derivatives. A brief selection is attached at the end of the slides.
• Our products carry the full documentation requirements, including material traceability and serial
numbers for identification, including line number, material spec, etc.,
• We are presently in the process of testing Lift-Off support designs from 26” to 48” line sizes. The
design, we believe will cater for up to 72” lines. Lift-Off bases can be made to lengths up to 27” at
the moment, but can be welded for extended lengths.
• “Lift-Off” pipe supports DO NOT REQUIRE ANY HOT WORK TO INSTALL. A MAJOR FACTOR IN
EXISTING PLANT INSTALLATIONS.
• “Lift-Off” compares very favorable to pipe shoe installation; in time, cost and corrosion mitigation.
• No limits on configurations i.e. guides, line stops, etc., The bottom of the line is always sitting on the
Lift-Off base.
• Can be combined with laminates for acoustic and vibration reduction/suppression.
• High compressive stress, with very good load bearing characteristics.
• Low coefficient of friction: µ=0.05 to 0.2.
Technical

18. • Can be used where existing pipe shoes have slipped of the pipe rack support steelwork, without having to perform
any Hot Work. These applications are obviously very complex and require proper stress analysis and process
checks.
• Designed and Manufactured in the US.
• Items can be electro polished and passivated, which we highly recommend. Other coatings i.e. Teflon™ can also be
applied to clients specification.
• Expected lifespan in excess of 20years as per CFR requirements.
Technical (continued)

19. • Our products carry the full documentation requirements, including material traceability and serial
numbers for identification, including line number, material spec, etc.,
• All parts are trial assembled before shipment, disassembled and marked accordingly.
• Full installation instructions and necessary tools are supplied with each support.
• Can be shipped worldwide from Lake Charles, LA or Houston, TX.
• 24/7 Service.
