New Pipe Inspection 

Let OilPro decrease your risk of running an unfit pipe into service through industry-leading new pipe inspection services that concurrently use multiple NDT methods, including ultrasonic and electromagnetic.

OilPro provide:

• Verification of internal dimension requirements with the FLD (Full Length Drift) test.
• Magnetic particle and visual testing referred to as SEA (Special End Area) by ASNT-certified Level II inspectors.

Supplementary inspections may be required to cover proprietary connections not covered by API/ISO standards. To confirm compliance of threads, thread gauges are used in accordance with API-recommended practices to confirm each element of a machined connection.
 
OilPro also provide wall data packages for detailed reporting or full mapping of each pipe: locating the thinnest wall, maximum wall, average wall, cross-sectional area and ovality of the tube body.  Inspections are carried out to written operating procedures:
Established by API Q1/ISO 29001 quality standards specified for the technical delivery conditions of steel pipe products  Casing, tubing, drill pipe, line pipe, coupling stock and accessories established by API 5CT/ISO 11960 requirements for PSL-1, PSL-2, PSL-3 product specification levels.

Tube Body

Eddy Current (Pipe grade)
For grade comparison, an electromagnetic eddy current method is used to monitor pipe's grade as each length is inspected with reference to the standard.

Ultrasonic (FLUT)
Ultrasonic examination of upset areas for the detection of transverse and three dimensional flaws on the inside and outside surface of the tube is performed. The critical area is also covered.
For detection of wall thinning areas and actual wall measurements, a compression wave ultrasonic sounds propagates from the external surface to the internal surface.

Electronics Magnetic Induction E.M.I. for continuous wall loss measurements.
For detection of longitudinal defects, an active magnetic field is induced into the pipe as it enters the AMALOG electromagnetic inspection station.
For detection of transverse defects, an active magnetic field is induced into the pipe as it enters the electromagnetic inspection station.

Full Length Drift (FLD) Inspection
Full length mechanical measurement of outside diameter is performed for identification of external wear, dents, mashes, slip area and stress induced diameter variations.
For verification of pipe internal diameter, the correct DRIFT mandrel is to be passed through the entire length of each casing and tubing and through the upset length of drill pipe. The drift mandrel shall pass through the pipe upset freely using a reasonably exerted force that does not exceed the weight of the drift mandrel.

Wall Data – specific values
Ultrasonic wall thickness measurements of each joint of pipe are documented in a methodical process. OilPro bespoke Third party Software gathers each data point to create a detailed report. Once the unit has been standardized scanning will begin.

Wall Mapping – all values
Ultrasonic wall thickness measurements of each joint of pipe will be documented in a methodical process. Once the unit has been standardized scanning will begin. Several hundred data points per transducer, per revolution is attained and stored. The exact number depends on the size of pipe being processed. There is a direct relationship with the pipe Outside Diameter, instrument pulse repetition rate and pipe surface speed.

Pipe Ends

API Thread Inspection
API threads on new tubular goods are measured for compliance with API dimensional specifications for lead, height, and taper (thread run out on buttress-thread casing is also measured). Thread protectors are removed and threads are cleaned and examined for visually identifiable manufacturing defects and mechanical damage. Thread compound is re-applied and thread protectors are re-installed.

Clean and Visual Thread Inspection
Threads are cleaned and examined for visually identifiable manufacturing defects, corrosion, and mechanical damage. Thread compound is re-applied and thread protectors are re-installed.

• Ring and Plug Gauging
  Ring and lug gauges are hand applied to threads to check relative connecting size and standoff. Threads are examined for visual defects.

Special End Area (SEA) Inspection
Magnetizing equipment is developed in separate stages to induce longitudinal and circular magnetic fields into the pipe end areas. Magnetic particle inspection is performed on the inside and outside surfaces of the end areas including the pins, coupling, threads, and upsets to detect imperfections of various orientations. Exposed threads and seals are cleaned and examined for visual defects and mechanical damage. Wet fluorescent inspection commonly known as "Black Light" is more sensitive than they dry particle technique for finding smaller flaws.
