The CASE services are about solving problems. By working closely with customers, we learn about the challenges they face in their facilities. This knowledge enables us to follow a scientific approach while developing instrument solutions for their applications, ensuring the one we deliver fully meets their needs. It also helps us support our customers if and when something fails.
If required, we provide instrument audits, which involve reviewing and analyzing existing temperature and pressure instruments. Once all instrumentation is reviewed and analyzed, we provide full documentation detailing each instrument’s current performance, potential problems, and appropriate solutions for optimal productivity and safety.
In addition to reviewing your application, identifying your instrument requirements and restrictions, and recommending products tailored to your needs, our Critical Application Solutions Experts services provide:
For customized testing, we recreate your process and process conditions in our CASE engineering lab to determine and/or verify product quality and performance.
If and when a product fails, our team determines the cause and works with your team to prevent similar failures in the future. We provide both on-site and off-site failure analysis with options for remote or virtual testing.
We standardize the organization of the storeroom to improve your logistical operations, decrease your inventory requirements, and maximize your cost savings.
As part of our in-facility visit, we can provide training to you and your employees as needed. The CASE services also offers webinars and on-site Lunch & Learns upon request.
Our product testing lab hosts vibration/shock, thermal, and proof/burst/cycle testing. In our metallurgical lab, we conduct optical microscopy, metallography, and X-ray fluorescence (metal identification). We also partner with outside labs for chemical analysis and electron microscopy operations.

CASE Study 1
Added Protection for Refinery's HF Alky Unit
CASE Study 2
Minimized Extreme Effects for Gauges In Petrochemical Application
The customer: A refinery with a hydrofluoric acid (HF) alkylation unit—also referred to as an “HF Alky” unit. These units are used in petroleum refining operations to convert isobutane and alkenes (primarily propylene or butylene) into alkylate, which is used to make gasoline.
The problem: Hydrofluoric acid is hazardous and corrosive and, if accidentally released, can form a vapor cloud that causes severe reactions and possible fatalities.
The CASE diagnosis: After visiting the plant, reviewing the application, and performing on-site analysis of the gauge in use, Ashcroft recommended a gauge assembly with additional safety features for improved protection.
The CASE solution: The gauge assembly we recommended to the customer featured the ALD (Acid Leak Detection) system. Its key benefits include:
Tamper proof design with the gauge welded to the seal
Visual indication of leaking process media
Dual containment for safety
The customer: A refinery using pressure gauges for a variety of applications.
The problem: The gauge pointer indicated 42 psi with no applied pressure.
The CASEdiagnosis: After providing an on-site pressure instrument audit where each gauge and process was documented and logged over a two-day period, Ashcroft noted signs of extreme service, such as elevated temperature, vibration, pressure pulsation, or damage. We diagnosed that 17% of all gauges exhibited signs of damage, including discolored fill, overpressure, liquid fill leaks, water ingress, broken windows, and/or loss of pressure containment.
The CASEsolution: After determining the cause of the problem, we provided the customer with our recommendations on how to prevent the issues we found in the audited gauges. Recommendations included:
Replacing the current gauges with PLUS!™ Performance technology for most gauges at the facility. The technology would allow for a 50% reduction in gauge inventory, elimination of liquid fill leaks and fill discoloration issues, and dampening of the effects of pulsation and vibration for a longer-lasting gauge.
Adding a pressure limiting valve (PLV) for when overpressure exceeds gauge proof pressure.
Glycerin-filled case gauges were also recommended for the small percentage of severe vibration applications.
An optional IP65 weatherproof gauge case to prevent water/moisture ingress and featured an acrylic gauge window to reduce the risk of the window breaking in the future.
