Local inspection of Gas pipeline by LRUT (1st phase)

Local inspection of Gas pipeline by LRUT (1st phase)

Guided Wave testing (GWT) is one of latest methods in the field of non-destructive evaluation. The method employs mechanical stress waves that propagate along an elongated structure while guided by its boundaries. This allows the waves to travel a long distance with little loss in energy. Nowadays, GWT is widely used to inspect and screen many engineering structures, particularly for the inspection of metallic pipelines around the world. In some cases, hundreds of meters can be inspected from a single location. There are also some applications for inspecting rail tracks, rods and metal plate structures

The 1st phase of this project was done by CAST in 2014 on plate and plan for 2nd phase is implementing on pipeline.

Magnetic Flux Leakage (MFL) tools identify and measure metal loss (corrosion, gouges etc…) through the use of an axially oriented applied magnetic field. An axial MFL tool induces a magnetic field in the pipe by using powerful magnets to magnetize the pipe wall to saturation. When corrosion or other degradation of the wall occurs, the pipe wall thickness is reduced. At areas of corrosion (reduced wall thickness) the amount of magnetic flux carried is less than that with full wall thickness. This means that there is leakage of magnetic flux at these areas. The reduction in the wall thickness at both outer and inner walls of the pipe can cause the same effect. The tool locates and records magnetic flux anomalies in the pipe and the recorded magnetic flux data is converted to provide an indication of metal loss in the pipe. Iranian MFL Pig was developed by cooperation of Segal Pardazesh Company, Petrogas and Faculty of engineering of University of Tehran. In this project CAST was the supervisor of project.

Design and Construction of Iran Pipeline High-Tech Center (IPHTC)

Design and Construction of Iran Pipeline High-Tech Center (IPHTC)

The main purpose of this project is to design and construct a high-tech test-center, in order to evaluate the effects of various processes and operations being used in the pipeline system and gas transmission. IPHTC is to investigate and certify proper functionality of the devices and procedures used in the transmission pipeline network in a cost-effective and low-risk way, without causing any disturbance in the operations or putting the national network at risk. Several operations will be examined and certified in IPHTC including various maintenance processes, e.g. cathodic protection systems, pipeline repair, pigging etc. Also, IPHTC provides professional training in various fields.

In the first phase of the design and construction of IPHTC project, the conceptual design of different sections as well as test center layout has been done by Center of Advanced Systems & Technologies (CAST). Furthermore, the amount of required investment and the road-map of the construction of IPHTC specifying sub-projects and the execution priorities, is determined. This phase was finished in 2015.
