Our Services

The TI-18 ultrasonic inspection process includes sixteen (16) flaw detection transducers, coupled with two (2) compression wave thickness transducers provide an inspection unequaled in today's marketplace. Flaw detection transducers, set at increments of twenty-two and one half degrees provide total analysis for all imperfections regardless of their orientation. Transducers at each end of the inspection array are capable of interrogation of imperfections within two (2) inches of the exposed plain end of the pipe. Due to the inherent flexibility of the array setup, requested customer specifications can easily and quickly be set.

The width of the transducer's beam, frequency and size, are used to calculate the maximum helix permissible for any given diameter and wall thickness of material being inspected. This helix is constantly being recomputed and displayed on a digital readout by a microprocessor driven totalizer.

The TI-10 ultrasonic inspection process is intended for those customers that want an inspection that is equivalent to standard ultrasonic inspection offered in today's marketplace. Not only is this process sensitive to those imperfections that occur in the longitudinal and transverse geometrics, but also included are four (4) oblique flaw detection transducers, set angles established by customer specifications. The associated production speeds approach those obtainable by EMI (Electromagnetic Inspection).

Although the TI-10 inspection uses less transducers, all other associated criteria of the TI-18 inspection is incorporated to insure the highest quality available in the marketplace today. 

The TI-6 ultrasonic inspection process has all the features of the TI-10 process described inthe previous paragraph, with the exception that no oblique angles are included. This inspection process is provided specifically for the client who is primarily interested in an inspection equivalent to EMI, but with improved sensitivity to internal imperfections and an enhanced wall thickness measurement.

Gamma systems used in today's EMI machines indicate relative wall changes based upon a known area thickness. At best, coverage of the pipe wall is about twenty-five percent (25%). The TI-6 inspection, unlike the gamma systems, offers real time ultrasonic thickness inspection based on the actual velocity of the material being inspected. The data provided by this type of inspection offers accuracy of approximately plus or minus one thousandth of an inch (.001"). The inspection coverage is a minimum of one hundred and ten percent (110%), and is unequaled by today's gamma systems.

Ultrasonic scans of the weld area of the pipe, using the proper transducers and inspection according to TI evaluations of the material. Special customer requirements will be provided with individual quotes.

The latest technology required to reach the world's deepest oil and gas well depth, is Technical Industries, Inc., proprietary latest innovation. Now our customers can view, (walk) the pipe from inside, outside, and as a flat plate, stop at any point and view the wall thickness, and condition of the pipe. By using the proper algorithm you can calculate the burst rate, collapse rate, and (tensile strength) pull rate of each joint, obtain a permanent record, and by comparing recent inspections to previous ones, thus enabling the client to project future life expectancy, and usage of the pipe.

1) Includes the calculations of all the readings within 1/4" CSA slice.
2) Recording the minimum, maximum & the average of the 64 points (1/4" each) of the CSA slices. Offered only with Full Length UT TI-18 which includes scanning the pipes for defects every 22.5 degrees along the surface of the pipe.

This Technical Industries, Inc., proprietary technology provides a virtual image of the inspected pipe in a 1/4" (CSA) helix. The data is stored on a server. This provides the customer with a 3D view of the pipe condition of the inside and the outside. Also the pipe can be viewed as a flat plate. The customer can stop at any point and examine the condition and read the wall thickness within 2/1000" accuracy. By using the proper algorithm, the customer can calculate the burst, collapse, and tensile strength of each pipe. The customer will be able to compare previous conditions to a recent one and be able to project future life expectancy of the pipe. This service is provided with Full Length UT TI-18 which includes scanning the pipes for defects every 22.5 degrees along the surface of the pipe.

This technology includes the recordation of all wall thickness data of the pipe, and provides 360 wall thickness readings for each 1/4" CSA slice all along the length of the pipe. One reading for each degree along the circumference of the 1/4" CSA slice. The data is compiled using Technical Industries, Inc., proprietary software in order to display the pipe in 3D virtual imaging. This service is offered in conjunction with Full Length UT TI-18 Visonic™ services.

Usually used for pipe with wall thickness not to exceed 0.430" using Technical Industries' four-function electromagnetic inspection unit, oil country tubular, in sizes 2-1/16 inch through 13-3/8 inch diameter, can be scanned for longitudinal, transverse and wall thickness anomalies, plus pipe grade verification.

To locate the longitudinal anomalies, a transversely oriented active magnetic field is induced into the tubular to be inspected as the pipe is conveyed through the inspection unit. Transducers, fixed at a ninety-degree (90°) angle as referenced to the magnetic field, detect "flux leakage" caused by any imperfection whose depth and orientation coincide with the longitudinal calibration and are recorded on a strip chart for later investigation.

To locate transverse and three-dimensional anomalies, a longitudinal magnetic field is induced into the pipe body, generating a magnetic field in excess of 850 free air gauss. Eight detection shoes, containing transducers, ride on the outside surface of the tubular being inspected. All "flux leakage" caused by transverse or three-dimensional anomalies are recorded on a strip chart for further investigation.

To examine the pipe wall to determine acceptable wall thickness, a radioactive beam and a detector mechanism are used (gamma ray). Output of this wall thickness detection system is recorded on a strip chart recorder for further investigation.

To verify pipe grade, a system measuring material permeability against a known standard, is used. If a discrepancy is noticed, an audible warning is generated and is followed by manual confirmation of the pipe grade.

Eight electromagnetic transducers mounted inside a circumferential aluminum cylinder designed to fit firmly on the outside surface of the pipe, travels along the length of the pipe searching for transverse defects generated by disrupted longitudinal magnetic field, the process is usually used to inspect used drill pipe (To satisfy API RP 7G Section 10 and used drill pipe DS-1 Inspection Category 3, 4 & 5. TH Hill DS-1 Standard).

The entire length of the tube excluding tool joints or connections will receive OD gauge inspection. If abnormal OD is detected, an ultrasonic compression instrument for wall thickness at maximum wear will inspect the area that records the most OD wear, and the readings will be recorded.

A circumferential field is induced into the pipe to be inspected, using a capacitive discharge system for longitudinal defects of adequate size for the material being inspected. The full length of the tubular is visually checked or the outside for the inside for any discontinuities. Dry iron powder is than applied to the entire outside or inside surface. All powder accumulations caused by "flux leakage" at the site of an anomaly is probed and if insufficient to cause rejection of the material, are removed and the surface contoured.

This inspection process, using finely ground iron powder suspended in a fluid, is used to inspect the ends of ferromagnetic tubular. The area to be inspected must be thoroughly cleaned before beginning the inspection process. This is followed by a visual thread inspection. A magnetic field, whose direction is appropriate for the inspection being performed, is then induced into the tubular. A bath with suspended fluorescent iron particles is then applied to the area viewed under an ultraviolet lamp. Any anomalies found will be probed for depth. In the event the anomaly is insufficient for rejection of the material, the anomaly will be removed and the area contoured.

Ultrasonic end area inspection is performed on material that is either non-ferromagnetic or where the customer is concerned about imperfections that are not readily discernable with other inspection methods (i.e., laminations). The entire surface area is scanned, for ten inches from the end of plain end pipe or from the last thread on threaded pipe, using the appropriate transducer coupled to shear wave instrumentation. Imperfections found during the inspection process are further probed to evaluate their severity. If the imperfection is not severe enough to cause rejection of the tubular and it is removable, it is then removed and the area contoured. Includes preparation.

Threads and shoulders are cleaned and visually inspected for service-induced defects, corrosion, mechanical, or manufacturing irregularities. Thread compound is re-applied, and thread protectors re-installed, when provided.

For the greatest part of all the inspections performed by Technical Industries, Inc., it is necessary that the pipe to be inspected be free of any foreign material that could degrade the inspection process. This is especially true for the end area inspection. The preparation process requires that the pipe be cleaned thoroughly for a distance of twenty-four inches (24") from each end of the pipe on both the external and internal surfaces. For threaded pipe, the completion of the process requires a specific compound applied to the threads and the protectors replaced and tightened to the appropriate torque.

Threads are cleaned and specified compound is applied and the protectors replaced and tightened to the appropriate torque.
