The company's business activities include engineering, construction, safety, turnaround and maintenance services, manufacturing, distribution, cured-in-place pipe (CIPP), installation, coating and insulation, cathodic protection, research and development and licensing.
Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes ...
This is a list of Superfund sites in Missouri designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

DCVG (direct current voltage gradient) is a survey technique used for assessing the effectiveness of corrosion protection on buried steel structures. [1] In particular, oil and natural gas pipelines are routinely monitored using this technique to help locate coating faults and highlight deficiencies in their cathodic protection (CP) strategies.
An anodic protection system includes an external power supply connected to auxiliary cathodes and controlled by a feedback signal from one or more reference electrodes. [3] Careful design and control is required when using anodic protection for several reasons, including excessive current when passivation is lost or unstable, leading to ...
Weldon Spring Ordnance Works (WSOW) was a 17,323-acre (70.10 km 2) U.S. Government-owned, contractor-operated (GOCO) facility in St. Charles County, Missouri, 55 km west of St. Louis. [1] The site was originally operated by the Atlas Powder Company during World War II from 1941 to 1945 to produce explosives . [ 1 ]
[23] [32] Cathodic protection was provided to resist corrosive action from the Bay's salt water. [ 29 ] The project cost approximately $180 million in 1970 (equivalent to $1.09 billion in 2023 [ 34 ] ), [ 35 ] [ 36 ] with $90 million of that cost being spent on construction, the remainder going towards laying rails, electrification, ventilation ...
The Czecho-Slovak Protective Society, headquartered in St. Louis, Missouri, joined in organizing the Czechoslovak Society of America in 1933. That organization, based in Lombard, Illinois changed its name to CSA Fraternal Life in 1982. [5] Č.S.P.S. stands for "Česko-Slovenský Podporující Spolek" (Czech-Slovak Protective Society).
