Precision Flange & Machine Inc. operates a very strict non-destructive testing program with zero tolerance for failure.
We have invested in state of the art equipment that is at the forefront of the NDE industry. Training and qualification
is of the upmost importance and is the backbone of our NDE operations.
All of our NDE is performed in house with the exception of radiography (X-ray) our inspectors are all qualified per ASNT
SNT-TC-1A Level II minimum and we have a NDE Level III on site overseeing and approving all testing activities and
procedures. When it comes to Quality and reliability of your products Precision Flange & Machine is the place to go.
Whether you are purchasing one of our products or have a product you need tested we will be more than grateful to
serve you. Please take a minute to review the testing services that we currently offer below.
Phased Array Ultrasonic Testing of Welds
Phased array ultrasonic testing of welds is an advanced ultrasonic testing technology that is now accepted by ASME to
replace radiography (X-Ray). Phased Array technology uses at least 16 elements all configured into one transducer and
allows the technician to use a broad spectrum of angles simultaneously (ex; 35° to 70° in 1° degree increments).
The technology also allows you to steer and focus the ultrasonic beam to a desired location or depth allowing for the
inspection of complex geometry and increases the probability of detection of defects.
A technician will record the ultrasonic data and create and image (as seen above) that can be reviewed by our level III
or emailed, printed, or faxed for client review and retention of testing records were as in conventional ultrasonic weld
inspection this is not obtainable you would only receive a pass or fail statement.
This method of testing is much faster and more sensitive than conventional ultrasonic testing and radiography which allows
us to provide you with your product and results in a much quicker timeframe and provide you with more reliable information
about your product.
As you see in this next video, Precision Flange & Machine has acquired an ultrasonic plate scanning cart which allows the
inspection of very large thick steel plates in a very short amount of time with recordable results.
The purpose of this inspection is to inspect and locate laminations in steel plates and allows us to rapidly certify
product to specifications such as ASME SA435 & SA578 Level A/B/C.
Ultrasonic Volumetric Inspection
Utilizing our ultrasonic testing equipment we have the ability to volumetrically inspect a wide range of materials and
configurations. This allows us the ability to inspect our products or provide you with a service to ultrasonically
inspect products such as forgings, flanges, fittings, pipe, tubing, bolting materials, plate, valves, and castings.
Liquid Penetrant Inspection
Liquid penetrant inspection is a great tool to use for the inspection of non-ferrous materials such as stainless steel.
This method can be used to inspect large surfaces and is capable of detecting defects open to the surface. We utilize
several different methods of liquid penetrant testing as you can see in the picture of the ISO 3452-3 NiCr crack panels
the fluorescent liquid penetrant is much more sensitive to small defects than the visible red dye.
Magnetic Particle Inspection
Magnetic particle inspection is utilized for the detection of surface and near surface defects in ferrous materials. This
type of inspection is done by magnetizing the material using AC or DC current and then an oil is applied the carries fine
magnetic particles that are dyed fluorescent or black particles. When a defect is present the particles are attracted the
magnetic leakage and creates an image of the discontinuities. One example of how we apply this method to our processes is
the inspection of scraper bar attachment welds in butt weld tees.
Visual & Dimensional Verification
Precision flange & machine takes pride in providing quality and accuracy we utilize the most current and up to date precision
measuring tools & devices in our visual and dimensional verification processes.
Positive Material Identification
We offer a couple of different methods of positive material identification as you can see in this photo.
The 1st method is X-ray fluorescent positive material identification which allows for rapid screening and alloy verification.
The second method is optical emissions spectrometry, this method allows for the verification of lighter elements such as carbon,
When special chemistry is critical this is the method that we utilize to assure the proper chemical values are being supplied.
Positive material identification reports can be provide upon request.
Hardness is and important physical property of steel it provides with the materials ability to with stand indention and has a
direct correlation with the tensile strength of an individual piece of material.
We utilize the Brinnel and Rockwell testing methods for testing of hardness for conformance with various specifications such
as NACE MR0-175. Hardness testing reports can be provided upon request.
The control of ferrite in austenitic welds is becoming more and more common this is not an issue for Precision Flange & Machine.
We have invested heavily in developing special welding controls and procedures to control ferrite levels in the weld metal of
our products.We utilize the Fischer FMP30 ferritescope for our in house ferrite testing and are capable of testing austenitic
stainless steels & austenitic/ferretic stainless steels (duplex grades). Ferrite testing services and reports can be provided upon
We currently use leak testing in the manufacturing of our reinforced laterals. Once the reinforcement pad is installed we
pressurize the inside of the repad to 15psi and apply a bubble solution to ensure the reinforcement pad is fully sealed and we
provide a leak testing certification.
