A Thorough Visual Inspection of Possible noticeable external damages inflicted on the pipe is performed; most damages encountered arise from handing of the pipe, such as dents and mashes. Other types of flags will be external corrosion, laps and straightness
Both pin and box ends are thoroughly cleaned and visually evaluated for any damages such as dents , corrosion, galled threads etc.
Wire Brushing, High Pressure Water Blasting or rattling to remove rust, scale and other debris.
By using a special portable device with calibration blocks, our technicians are able to go on location, test and compare the grade of pipe with standard API tubular goods.
A thin rust preventative coating is applied internally or externally to maintain the integrity of the pipe, customer to specify coating.
Bent pipe is straightened using a mobile hydraulic press unit
Using a specialized Electromagnetic unit, detection of transverse or 3-dimensional defects can be located. Some locations are equipped with 4-function EMI units to detect longitudinal defects & wall loss in addition to the aforementioned.
Using various API gauges, such as thread taper, lead and depth, we are able to measure the connection in order to verify it is within API tolerances.
Wall thickness is then verified by using ultrasonic readings to prove-up areas in question.
Utilizing a Capacitive Discharge Unit, the tubular full body is magnetized. Longitudinal defects are identified by using dry iron powder sprinkled over the entire external surface of the pipe.
A thorough Visual Inspection of possible noticeable external damages inflicted on the pipe is performed. Most damages encountered arise from handing of the pipe, such as dents and mashes .Other types of flags will be external corrosion, laps and straightness.
Using a handheld mechanical device, we are able to verify whether the diameter of the drill pipe body (full-length) is within API tolerances.
Both pin and Box ends are thoroughly cleaned and visually evaluated for any damages such as dents, corrosion, galled threads etc.
Using a specialized Electromagnetic unit, detection of transverse or 3-dimensional defects can be located. Some locations are equipped with 4-function EMI units to detect longitudinal defects and wall loss in addition to the aforementioned.
refaced to within the stipulations of APIRP-7G & GP standard. Drill String and Bottom Hole Assembly Inspections are normally carried out in accordance to one of the following standards.
In order to protect the client’s drill pipe tool joints and center wear pads from excessive wear while drilling in abrasive environment, hard banding is applied in one (1) inch bands around the circumferences of the tool joints and center wear pads. Various mesh size of tungsten can be applied with the band.
As an alternative to tungsten, we can also apply chromium-based materials like Anti-wear. This type of product application reduces casing wear while protecting tool joint of the drill pipe.
Bent pipe is straightening using a ram-type, hydraulic press.
A shear wave ultrasonic inspection is performed on the upsets and friction welded areas of the drill pipe. This service is performed in order to locate fatigue cracks.
Controlled automatic welding procedures are used to build-up the outside diameter of worn tool joints to their original size .Instead of scraping drill pipe whose tool joint OD’s are below API specification, applying the same concept as hard banding is able to literally reconstruct the OD of your tool joints back to specification, thus salvaging the premium pipe body saving the clients from unnecessary expenditures.
Mill slotting is performed by cutting a shallow, round or elongated slot into the body or tool joints of drill stem components .In order to cut into and along the pipe, a drill specifically designed for this use is utilized. Like the device used for hardness testing, the size and weight of the slotted machine allows our operators to go on-site and perform the job at the clients’ yard. Due to the nature of this service, client specifications are to be followed providing that it does not force the material to deviate from the API’s specification.
