Automated non-destructive inspection system for girth welds

of trunk pipelines uniscan GW

Comprehensive pluggable system for non-destructive inspection methods (visual, ultrasonic, digital radiography) for storage and analyzes test results including GPS coordinates of test object.

UNISCAN GW-AUT

UNISCAN GW-AUT

• Simulation and step-by-step setting helps us to

quickly configure the system;

• High reliability, precise information and accuracy

of obtaining the actual dimensions of defects;

• UNISCAN GW-AUT allows inspections to comply

with the API 1104, ASTM E-1961, DNV-OS-F101,

API-5L.

UNISCAN GW-AUT is a complete solution for automated ultrasonic inspection of girth welds, using Phased array technology (PAUT), Time of Flight Diffraction (TOFD), Creeping wave (CRW) and other advantages Conventional UT.

Advantages of UNISCAN GW-AUT:

SOFTWARE:

• Universal system, for inspection girth welds

of pipelines with a different diameter and

thickness;

• Wireless control system;

• Real time inspection with using wireless control

(laptop, tablet, phone);

• Short inspection cycle allows for high

performance;

• Automatic creation of inspectionreports;

• The user interface is easy to learn anduse, provides high efficiency;

• Special software for collection andanalysis of data;

• Operate detection and analysis thedefects of girth.

UNISCAN GW-DR

UNISCAN GW-DR

TestXray digital radiography system provides:

• Lower inspection costs by eliminating consumables

(X-ray film and film processing chemicals), film

processing equipment, film storage facilities;

• Compatible with any X-ray source and any crawler;

• Inspection results obtained online make it possible

to correct welding settings to avoid more defects;

• Perfect conditions for image examination (zoom,

optimal contrast, image enhancement proce dures)

and inspection protocol preparation;

• Easy to use database.

Mobile digital radiography system is intended for single wall or double wall penetration of ∅ 300–1420 mm pipe welds for pipeline construction or repair.
