Special Process and Component Validation Services


Borescope Inspection
Pressure Testing

Validating the authenticity of the work performed on your parts can be difficult to confirm. MISTRAS’ special process services take the guesswork out, as we adhere to strict requirements through every step of the process.

Following the inspection, testing, and maintenance service process, you’ll want to confirm the validity of the work performed on your components, to ensure it's in compliance with prime standards, or industry codes and regulations. With MISTRAS’ special process services, the process itself is validated, so if you can’t verify the results, rest assured, the process has been.

Abrasive Blasting

Abrasive blasting propels an abrasive material with significant force and pressure to roughen a smooth surface, smooth a rough surface, or remove any surface contaminants. MISTRAS often uses abrasive blasting to mitigate or remove corrosion, and prepare surfaces for coating applications.

Checking for corrosion is of the utmost importance when protecting your assets. By utilizing MISTRAS’ abrasive blasting service, you can keep your aerospace or other industrial components performing at the highest level. Our blasting solution is used to descale oxides from heat treatment on stainless steel parts, including plates, rotating engine fans, turbine disks, and more. Abrasive blasting can be used as a metal finishing component designed to give your parts a matte finish. This process helps to mitigate any harsh environmental build-up, while saving you valuable time and money.

High Humidity Test

As materials and metals each respond differently to humidity, MISTRAS' laboratory technicians combine humid environments with temperature, altitude, and other variable simulations to qualify components for operations in any environment.

MISTRAS high humidity tests, which are done in a sealed chamber and can reach temperatures up to 100°F, with humidity levels approaching 97%, help to combat potential integrity issues regarding your assets. By performing high humidity tests on materials such as stainless steel and other alloys, operators can check for crevice corrosion, pitting corrosion, and passivation issues, among various other abnormalities. After a typical monitoring period of 24 hours, MISTRAS’ technicians can provide detailed information on how your components may perform in harsh elements, ultimately saving you from untimely asset repairs and/or replacements.

Borescope Inspection

A borescope is an optical device utilized during visual inspections, consisting of a rigid or flexible tube with an eyepiece on one end, and an objective lens on the other linked together by a relay optical system in between. Borescopes are often used to conduct internal visual inspections in assets that cannot be easily seen with the naked eye.

MISTRAS’ borescope inspection solutions are an important method for protecting your assets and are commonly used on critical interior surfaces or hard-to-see areas of aircraft engines, gas and steam turbines, along with other industrial components. Our technicians perform visual inspection processes by utilizing high-end, 25x- magnification optical devices designed to identify any hidden abnormalities.

Pressure Testing

Pressure testing is a non-destructive testing (NDT) technique to determine if a pipeline, pressure vessel piping system, or other pressurized asset can safely withstand its rated pressure and free from leaks. Pressure testing can also be used to establish a pressure rating.

MISTRAS’ non-destructive testing (NDT) pressure testing services determine how “leak-tight” your assets are. By performing a series of tests on new, existing, or repaired components, our skilled operators can determine if your system is suited to withstand pre-defined pressure points.

Salt Spray Test

Salt spray tests are applied to measure a material's corrosion resistance to high-saline environments. A sample is subjected to a corrosive sodium-chloride solution, and is analyzed over time to determine its ability to withstand harsh environmental conditions.

MISTRAS’ salt spray testing solutions offer a simulated example as to how your components may perform when exposed to harsh environmental conditions. Placed in a controlled, saline-saturated environment, various parts such as stainless steel and other alloys react, therefore indicating how vulnerable they may be to open air conditions or various landscapes. By performing salt spray tests at designated intervals, MISTRAS can help to preserve the life of your assets, along with your overall budget.
