PRESERVING YOUR PIPELINE
Protective coatings are the first line of defense for the thousands of miles of pipelines in the world. At some point in their life span pipelines coatings need to be repaired or removed and reapplied to ensure durability and continuous corrosion resistance performance. Uncontrolled corrosion will lead to leaks, service interruption, and environmental disasters. This could be a costly process both environmentally and financially.
Precision Iceblast Corporation specializes in pipeline maintenance and repair coating applications for mainlines and girth welds. Liquid pipeline coatings applied on surfaces prepared using our proprietary ice blasting technology meet performance requirements set by CZA Z245.20, ISO 21809-3 and other major industry players. PIC practices are also endorsed by major suppliers of liquid pipeline coatings.
PIC utilizes ATEX rated equipment for dry ice blasting which allows for work without equipment or line shut down.
With equipment located in North America, South America, Southeast Asia, and the Middle East, PIC is ready for your next pipeline coating maintenance project.
ADVANTAGES OF CLEANING WITH DRY ICE
- Environmentally Friendly
- Less waste disposal
- No remaining blast media left behind
- No secondary waste generated
- No moisture left behind
- Provides cleanest surface for coating
- Non-abrasive & Non-conductive
- Does not damage surfaces
- Extends equipment life
- Minimal or no containment required
Leading Cause of Paint Failure
- Poor Surface Preparation
Why USE Dry Ice Blasting?
- Provides the most Superior prepared surface for recoating
- Dust Free
- Micro-Organisms removed/killed
- Chemical Free Substrate
- No Embedded Fouling
- All Contaminants removed
Dry ice blasting provides an environmentally friendly and cost-effective alternative to the conventional abrasive blasting. It reduces waste by 80-90% and reduces costs by about 25%. Dry Ice blasting is a simple, non-abrasive cleaning process that uses CO2 pellets as impact medium for removing surface contaminants without the use of chemicals, abrasive materials, high temperatures, or steam. The solid pellets sublime directly after impact on the surface, leaving no solid residue after blasting. The technique can be used for cleaning surfaces, removing paint, or stripping contaminants from a surface
PIC not only provides surface preparation and coating application services; it also provides technical assistance in selecting the proper pipeline and field joint coatings.
When a substrate is heavily corroded or if a profile is needed for a particular coating, additional steps are taken to further mitigate the deterioration. First, a dry ice blast will be performed to provide a clean substrate. Once the substrate is cleaned, we determine areas that may not have an anchor profile and address those areas with a dry ice / garnet slurry solution.
This is very beneficial as a minimal amount of abrasive needs to be added to the dry ice so you are left with very little dust, clean up, or disposal. A near white metal surface is still created and an anchor profile is achieved which is typically between a 1.5 to 2.5 mils. The benefits to this process are a dramatically reduced amount of abrasive, the cleanest possible surface, and an anchor profile achieved.
Traditional methods would be a straight abrasive blasting which would result in truckloads of abrasive and debris to remove afterwards. On average we can reduce waste by a minimum of 90% and upwards to 99% depending on deterioration levels. Any areas of coating remaining are considered a sound solid substrate and acceptable to receive a new coating.
