JENSEN HUGHES is the global leader in specialty engineering and consulting services for the built environment. We are a company of engineers, consultants, and scientists focused on evaluating risks and diligently developing the best, most cost effective safety solutions. We offer extensive, practical experience through countless projects, research and industry innovation. Our global clients include a majority of Fortune 500 companies and cover the following sectors: corporate real estate, education, energy, government, healthcare, hospitality, industrial, military, and transportation. PIPE CORROSION Our Power Systems Division offers additional resources that include solutions for pipe corrosion inspection and information on the 50 Year Sprinkler Testing The corrosion of fire protection systems can be costly and have detrimental effects on the reliability and anticipated operational performance of sprinkler systems. In some cases, the severity and extent of corrosion can impact the ability of a sprinkler system to control or suppress a fire. Corrosion and its products can limit or prevent adequate water flow in sprinkler systems. We work with metallurgical and water testing laboratories to implement a three pronged approach to investigate the extent, severity and root cause of corrosion in fire protection systems. A typical project will involve an examination of the sprinkler system, analysis of the water supply and system water, and a metallurgical examination. Findings of these investigations are used to develop solutions for remediation and are carried over to design practices employed by our staff.

PIPE CORROSION
Our Power Systems Division offers additional resources that include solutions for pipe corrosion inspection and information on the 50 Year Sprinkler Testing
The corrosion of fire protection systems can be costly and have detrimental effects on the reliability and anticipated operational performance of sprinkler systems. In some cases, the severity and extent of corrosion can impact the ability of a sprinkler system to control or suppress a fire.
Corrosion and its products can limit or prevent adequate water flow in sprinkler systems. We work with metallurgical and water testing laboratories to implement a three pronged approach to investigate the extent, severity and root cause of corrosion in fire protection systems. A typical project will involve an examination of the sprinkler system, analysis of the water supply and system water, and a metallurgical examination.
Findings of these investigations are used to develop solutions for remediation and are carried over to design practices employed by our staff.
INVESTIGATIONOur engineers have investigated corrosion in a variety of fire protection systems, including:
JJ Wet
JJ Deluge
JJ Dry Pipe
JJ Pre-action Sprinkler Systems
MATERIALSOur investigations include the following piping materials and components:

NU-WAVE TECHNOLOGY
Nu-Wave Technology provides inspection that utilizes a localized guided wave ultrasonic scanner to identify the condition of piping. The process can identify corrosion, tuberculation, Microbiological Influenced Corrosion (MIC), and wall thinning.
This technology works on all types of steel piping from 1-inch to 10-inch, either wet or dry regardless of system operation (flow or no flow condition). The scanning device is completely portable and does not require any special consideration other than access to the piping to be inspected. In addition the measurements can be made through most painted and coated surfaces.
This service can be in response to an observed adverse condition identified through testing (e.g. declining flow test results) or part of a predictive maintenance program to track and trend conditions before an issue occurs, streamlining the design and construction process.
50 YEAR SPRINKLER TESTING
Did your plant include a license renewal commitment to perform a 50 year sprinkler test? Is your plant insured by Nuclear Electric Insurance Limited (NEIL)?
NEIL Loss Control Standards state that inspection testing and maintenance is required for fire protection systems installed to meet NEIL Standards or credited as protected a structure
or equipment. NFPA 25 is the standard NEIL cites as the basis for testing. NFPA 25 requires sprinklers that have been in service for 50 years be replaced or a representative sample tested. With many plants constructed in the mid to late 1960’s, the 50 year window is quickly approaching.
Our company has the staff with the licensing and code knowledge to interpret licensing commitments, survey/inventory the plant, and recommend a cost effective and complaint solution.
