Non-Destructive Testing Services

Conco Non-Destructive Testing Services are performed for all utility, industrial and commercial customers on all types of tubing in condensers and heat exchangers included in the steam cycle, cooling water systems, service water systems and process systems. Non-Destructive Testing helps to prevent forced outages by detecting various defects such as pitting, cracking, corrosion, erosion, grooving, steam impingement and tube-support fretting that cause tube failures. Conco personnel are certified in accordance with the American Society of Non-Destructive Testing (ASNT) SNT-TC-1A guidelines. In addition, Conco follows the most stringent nuclear guidelines. Our customers realize significant economic savings from routine testing through improved reliability and plant availability.

Different Tubes
Require Different Tests

Condensers and heat exchangers
come in a variety of sizes, shapes and materials. Tube materials can include carbon steel, stainless steel, admiralty brass and Cu-Ni alloys. No single nondestructive technique can test
them all. It’s crucial to select a testing company that has the capabilities and experience to provide a variety of testing techniques for your different
tube materials. Also, understanding
site-specific  conditions and their
effects on tube material such as wall thinning, chemical attack and pitting is fundamental in selecting the right test for the job.

Eddy Current,
Remote Field
and Near Field Testing

Conco Eddy Current, Remote Field and Near Field Testing Services specialize
in finding tube defects in a variety of materials including stainless steel,
titanium, brass and Cu-Ni alloys.
Non- Destructive Testing can find defects ranging from pitting, cracking, corrosion, erosion, grooving and dents that cause tube failures. After testing, Conco provides each customer with a tube-by-tube analysis and full-color tubesheet map of the tested condenser or heat exchanger, giving a detailed assessment of the tubing.

Data Analysis

Depending on your requirements, our NDE analysts can provide on-site or remote data interpretation, utilizing
the most advanced software for
Eddy Current, Remote Field and
Near Field Testing. Conco analysts
will identify defects in your condenser
or heat exchanger tubing and provide
a comprehensive report of their
findings. We can even assist you in
theestablishment of a non-destructive testing program. This allows Conco
to trend the growth of previously identified damage within the condenser or heat exchanger. It also allows
Conco to monitor for any new damage mechanisms that may occur during the operating cycle. This is part of a preventative maintenance program that
Conco can help establish and maintain.

Tubesheet Mapping

This service provides an at-a-glance summary of condenser or heat exchanger condition. Upon completion of a comprehensive non-destructive testing evaluation, Conco can create a multicolor tubesheet map for graphic illustration of tube wall condition. The overall condition of the condenser or heat exchanger and any developing trends are obvious as
each tube’s condition is represented by
a different color or symbol.
