Engineers from the Packaging Technology sector of Savannah River Nuclear Solutions contacted Pacific Corrugated pipe with a unique request. They wanted to understand if corrugated steel pipe could be produced in such a way that two segment cans would "thread" into each other. If this could be achieved, both ends of the smaller diameter pipe would have welded end caps and a simple handle welded to one end. The other would remain open on both ends and later be installed into the existing disposal drums used in the nuclear waste control process.
In the grain belt of the United States farmers have been blessed with technological and genetic advances that have allowed them to produce corn and soybean yields that would be almost unbelievable to farmers 20 years ago. This over abundance, as good as it may sound to the general public, has created numerous issues for those producing the crops and those responsible for merchandising the crops(co-ops, processing plants, farmers, etc.) The largest and most pressing of these issues is storage of the harvest. Whether it be a more permanent flat storage facility, or a temporary outdoor “overflow” storage facility, proper storage of grain helps keep the product marketable for longer periods of time and allows producers to hold on to crops until pricing is more favorable or processing facilities are able to take physical delivery of the grain. When a producer’s or merchandiser’s storage facilities are improperly designed (i.e. the lack of proper airflow into grain piles), they risk the loss of millions of dollars in spoiled/rotten grain.
The Pennsylvania DOT project provided for the slip line rehabilitation of an existing 156 inch diameter steel structural plate pipe culvert crossing of State Route 3023 at White Creek in Susquehanna County, PA, located in the upper northeast corner of the state.

The Great Park project consisted of redevelopment of the former El Toro Marine base in Irvine, CA. The El Toro marine base was built after the bombing of Pearl Harbor to providea blimp base for antisubmarine patrols for the Los Angeles harbor. After World War II the based was repurposed to be the center for Marine aviation on the west coast. During the Korean War the base was used as a jumping off point for units headed for combat. During the ensuing years growth of Orange County resulted in a sea of subdivisions and development encroaching on the base. El Toro officially closed in 1999 and there were many discussions about whether the property would be converted to a regional airport or used for other purposes. Ultimately, the decision was made to use the property for community and residential development.

Indiana DOT specified two miles of 96” diameter Polymer Coated for storm sewer in Indianapolis, IN.
- Installed in 1988.
- Zone 4 North Dakota DOT Corrosion Map. “RED Zone” <400 Ohms*cm the highest corrosion zone in ND.
- No signs of corrosion,
- Mud splatter on the side walls and mud layered on the inverts.
- 4,000 LF 132” Diameter
- 1,000 LF 120” Diameter
- Constrained Site
- Integrated Manholes
After approximately 39 years of in-ground performance, 11 of the 13 Polymer Coated CSP crossings (14 total pipes) had a rating of 2 (fair with some wear, but structurally sound). One of the culvert inverts could not be observed, one was a twin culvert, and one of the culverts observed had a rating of 3 due to foundation of the roadway surface unrelated to the pipe.
When comparing the current condition of the polymer coated CMP to the plain galvanized end sections used on the inlet and outlet of the pipes, it is apparent the polymer coating has helped significantly increased the service life of the galvanized culverts. If these culverts were made of galvanized steel they would have probably already been replaced.
Based on the overall condition of the culverts after 40-years of performance and the very good condition of the polymeric coating on the interior of the pipes, it is believed the culverts will continue to perform for many years to come.
