Asset Integrity Management

 

Cathodic Protection

SD Green Energy have qualified manpower as per NACE requirement and undertake entire scope of activities for Cathodic Protection including Design, Supply, Installation, Testing & Commissioning, Post Commissioning, CP Monitoring & Maintenance, CP Surveys such as CAT/DCVG/CIPL for  underground Cross Country/CGD Pipelines and Equipment.

CP Surveying:

We undertake Pre Installation and Post Installation Surveys concerning Cathodic Protection Systems.

  1. Close Interval Potential Logging ON-OFF/CIPL Survey as Pipeline Health Survey
  2. Pearson Survey examine the Coating Condition of equipment
  3. Direct Current Voltage Gradient (DCVG) used for Inspecting coating of buried pipelines
  4. Current Attenuation Test (CAT) used to locate poor leaks and defects which drain out the current from systems.

CP Monitoring/Maintenance:

Test stations are provided at sufficient locations for current measurements which facilitate Cathodic Protection testing. We undertake scheduled monitoring of various components in CPS on daily, weekly, monthly, quarterly and yearly basis as required.

CNG Cylinder Testing

SD Green Energy has created State of the art CNG Cylinder Testing facility as per relevant Standards and Codes as prescribed by Chief Controller of Explosives Safety Organization, Government of India.

sd green energy Hydro testing facility uses Water Jacket Method for testing of Cylinders. Our Hydro close test jackets contain a Safety Locking Device, Burst Disk Crystals, a Drain Valve and a splash shield specially to take care of Safety while operating Cylinders. This Hydro Testing Facility is also designed as per U.S. Code of federal regulations, 49CFR180.205.

Safety Relief Valve Testing

Our test bench for safety relief valve testing contains Safe Locking Device and Operation Panel with required drain and vent valves to take care of Safety while operating. The Pressure Gauges being used are reputed and standard made with a tolerance of ± 2% accuracy. Our technicians have mastered the art of lapping valve sealing faces, an important aspect to ensure long term valve performance. Using an Industrial Diamond Compound we can achieve extremely flat finishes resulting in “bubble tight” leakage as required by the American Petroleum Institute Standard – API527. The SRV testing facility is designed for pressure up to 300 bar (g) and up to 8” flange size.

Our SRV testing ensures 100 % safety as per requirement of Chief Controller Of Explosives (CCOE) formerly known as PESO of components when subjected to service conditions.
