Contact Ultrasonics & Inspection Consulting performs upstream and downstream industrial inspections to provide our clients with quick, accurate, & reliable information along with the documentation for records of all inspections performed to ensure code compliance. All inspections are performed by American Welding Society Certified Welding Inspectors (AWS / CWI), American Society For Nondestructive Testing Level III technicians, or Level II technicians certified by company procedures that meet the requirements of ASNT recommended practice SNT-TC-1A. Reports can be completed and delivered electronically or handwritten.
Our technicians have many years of field experience performing structural integrity, safety, and nondestructive inspections in industries including:
Drilling Rigs (Land & Offshore) – Contact Ultrasonics performs API-4G inspections on masts or derricks, and API-Section 8 inspections on drilling tools by the American Petroleum Institute recommended practices. We perform structural integrity inspections, looking for stress cracking, on all drilling rig components including the mast/derrick, substructure, high-pressure mud lines, mud pumps, mud tanks, shaker skid, etc. We also perform safety inspections for OSHA compliance.
Chemical & Petrochemical Plants: Contact Ultrasonics performs On-Stream and Turnaround / Outage NDT inspections, for the plant inspection department or maintenance contractors, on various components including (but not limited to) piping, pressure vessels, heat exchangers, and storage tanks.
Products & Services
CWI / Visual
Visual inspection is one of the most utilized and proficient methods of non-destructive testing available. All visual inspections are conducted by certified inspectors with vast knowledge and experience in his/her field. Visual Inspections may be performed using the direct or indirect method. Examples of indirect visuals may include bora scope, remote video, etc.
Ultrasonic Flaw Detection – Shear weave & Straight beam
Ultrasonic Flaw Detection is a non-destructive testing procedure in which beams of high-frequency sound waves are used to detect surface and sub-surface flaws. The sound waves travel through the materials, then, are then reflected at metal interfaces capable of revealing discontinuities. With this test, the technician can determine the presence and location of imperfections such as cracks, shrinkage, cavities, bursts, pores, non-fusion, and other defects. This test is used for quality control and materials testing in all major industries. Ultrasonic flaw testing procedures include testing of forgings, castings, rolled plates, weld joints, and steel production. UT technicians also perform inspections on fabricated structures such as pressure vessels, pipelines, drilling rigs, ships, and other steel components. Flaw detection techniques include:
- Straight Beam Testing A longitudinal sound wave is induced into the part at a zero-degree angle for the detection of planar discontinuities (Laminations) parallel to the surface of the material.
- Conventional Shearwave A single sound wave is induced into the part at one angle for the detection of base material or weld discontinuities.
- Phased Array (PAUT) Multiple sound waves are induced into the part at multiple angles for the detection of base material or weld discontinuities. Phased array scans can be recorded and stored electronically for comparison with future scans or third-party interpretation.
Ultrasonic testing can also be used to measure the thickness of metal sections during manufacturing and maintenance inspections. Conventional UT is accurate, fast, and relatively inexpensive. These tests employ a transducer that emits ultrasonic pulses into the material which are then reflected to the transducer from the back wall of the material. Using calibration standards, material thickness can be accurately tested to within thousands of an inch. With the use of phased array equipment, corrosion scans can be performed and recorded electronically. Corrosion scans show a color scale picture of the scanned parts back wall, such as pits and wash-out areas.
