Our Services


Below are the services Aero-Flex can provide your company.

X-Ray - Radiographic Inspection


Radiography, or X-ray, checks a weld’s integrity in a nondestructive manner. X-rays and gamma rays pass through metal and other materials opaque to ordinary light and produce photographic records of the transmitted radiant energy. Since materials absorb known amounts of this radiant energy, the recorded X-rays reveal discontinuities and inclusions within the opaque material.

X-ray interpretation is crucial because developing the film can introduce marks, streaks, fog, and spots that may mask welding flaws. Since the angle of exposure also influences the X-ray, it’s difficult to confidently analyze fillet welds with this method. X-rays compress all of the defects throughout the thickness of the weld into only one plane and can exaggerate defects like porosity or inclusions. Generally, weld defects consist of a void in the weld metal itself or an inclusion that differs in density from the surrounding metal.

Aero-Flex works with a certified NADCAP facility to provide accurate and dependable radiographic inspections of your welds.

This leak detection technique locates surface cracks and pinholes not easily seen or detected by an air test or magnetic particle inspection. We apply a fluorescent penetrating dye to your part’s surface and wait for capillary action to draw the liquid into the surface openings. After removing the excess, a developer draws the penetrant to the surface.

We examine the result with ultraviolet light. The high contrast between the fluorescent material and the object makes it possible to detect minute traces of penetrant that indicate defects. Visible dye penetrant works similarly, but with a white developer — against which the dye penetrants create a sharp contrast visible in conventional lighting.

Parts must be cleaned and dried for inspection since foreign matter could seal cracks and pinholes, block the penetrant, and thwart the inspection. The process takes approximately one hour since the liquid needs time to absorb fully into discontinuities.

Pressure Testing


Hydrostatic testing
Standard testing detects leaks. Hydrostatic testing tests an assembly’s strength. We’ll fill your assembly with liquid while simultaneously evacuating its air. Using high-pressure pumps, we hydrostatically pressurize the assembly and test its ability to withstand the pressure for which it’s rated for a predetermined period of time.

Pneumatic testing
With our custom pneumatic and hydrostatic chamber, we can test your equipment with air under water at pressures of up to 20,000 psi. Obviously, only specialized applications require such a test. By using a compressed gas like nitrogen, CO2, or methane, a pneumatic test is more dangerous than its hydrostatic cousin due to the higher energy content. We limit these tests to low pressure or small systems. It operates on principles similar to your car tire pressure gauge.



This process locates and defines imperceptible discontinuities in any magnetic material, such as a weld or the adjacent base metal. You can employ it to inspect plate edges before welding, examine separate weld passes (or layers) as you proceed, or test the final repair. The inspection will detect both surface and subsurface cracks, incomplete fusion, inadequate weld penetration, and any defects in the metal.

The method places probes on each side of the area to be inspected, passing a high amperage through the workplace between them. This produces a magnetic flux at right angles to the current flow. When these lines of force encounter a discontinuity like a longitudinal crack, they divert and leak through the surface. Magnetic powder dusted onto the surface clings more tenaciously to an area of leakage than elsewhere, identifying the discontinuity for which you’re testing.

AGREEMENT – This agreement between the undersigned photographer (hereafter “Photographer”) and the undersigned client,
(hereafter “Client”) governs the assignment described in the accompanying price estimate/images, and along with these Terms
& Conditions, constitutes the entire agreement between the parties concerning that assignment.
ESTIMATES/BIDS – The fees quoted by the photographer are for the original job description as presented by the Client. Any
subsequent changes,whether made orally or in writing, may result in additional charges. The accompanying quote is a good
faith estimate of the time and expenses the Photographer anticipates.
INDEMNIFICATION – Client herby indemnifies and holds the Photographer harmless against all liabilities, claims, and expenses,
including reasonable legal fees, arising from the Client’s use of the Photographer’s work.
COPYRIGHT – Grant of any reproduction rights to the Client is conditioned upon receipt of the payment in full. All right not
expressly granted shall be reserved by the photographer.
ADDITIONAL USAGE - If Client wishes to make any additional uses of the photographs not covered in the initial agreement,
Client shall obtain permission from the photographer and pay an additional fee to be agreed upon.
EXCLUSIVITY – The photographs will be exclusive to the Client for the term of the licensing agreement, but no to exceed 5
years. The Photographer may use the photos in his own marketing materials at any time.
CANCELLATIONS, POSTPONEMENTS – In the event of a cancellation or postponement of a shoot by the client or subject after
quote has been accepted/PO issued, Client shall pay all expenses incurred by the Photographer up to the time of the
cancellation. If a shoot is cancelled within 24 hours of the departure for the shoot, client shall pay 50% of the anticipated
photographic fee and 100% of the anticipated fees of any subcontractors booked for the job.


This sensitive leak detection method generates a high vacuum in your assembly by attaching the spectrometer to it. We then flood the assembly’s exterior with helium, whose tiny atoms penetrate the smallest openings and are drawn back into the mass spectrometer for detection and quantification of the size of any leak discovered.

This method can detect even the smallest of leaks in your Metal Hose, Pipe Assembly or Tube Assembly that a Hydrostatic or Pneumatic pressure test may not detect.



Aero-Flex Standard Cleaning

For all welded joints, Aero-Flex Corp. adheres to a rigorous multi-step cleaning and passivation process. When you weld stainless steel, the heat causes the material’s residual carbon to rise to the surface. These carbon deposits can eventually cause rust on your welds, especially in the heat-affected zones. To prevent this future damage, Aero-Flex Corp. applies two separate acid washes to the weld zone, effectively “pickling” the joint. This eliminates the carbon deposits and the chance of post-weld rust. The last stage involves a caustic dip to neutralize acids.

Aero-Flex High Purity Cleaning

If particulate count or residue contamination is a concern, Aero-Flex will perform high purity cleaning to the highest industry standards and in compliance with your specific requirements. The clean room is ISO 14644 compliant with environmentally controlled work areas and validated sampling processes.
