1- Repair Sector
For repair and reinforcing transmission pipeline we use composite sleeve which is called Zerehloole. Zerehloole is easy, fast, economical and permanent pipeline repair. With Zerehloole, there is no need to welding, cutting pipeline or shut down.

2- Inspection Sector
In the field of inspection and survey of pipeline, we use different techniques like:

• External corrosion direct assessment (ECDA)
• DC voltage gradient technology (DCVG)
• Close interval potential technology (CIPS)
• Soil resistivity, pH & bacteriological evaluation
• Internal corrosion direct assessment (ICDA)

3- Integrity management system Sector (PIMS)
We use pipeline survey data analysis software for determining:

• Pipeline and Coating defects (position and size)
• Efficiency of cathodic protection
• Corrosion rate
• Remaining life time of pipeline
• Points which is need to repair or replace
• repair method
• Inspection interval
• Safe condition 
• Recommendations for increasing cathodic protection efficiency
• 5,10,20 year plans for monitoring and maintenance
