Cathodic Protection Services

Cathodic protection first became common place during the 1930s in the United States, where it was used to control the corrosion of pipelines carrying high pressure hydrocarbons. Now after more than 70 years, cathodic protection is known as one of the most effective techniques in the mitigation of corrosion. Cathodic protection systems with remote monitoring and control equipment are capable of controlling corrosion of steel structures in soil or marine environments very effectively. Payesh Sanat Novin (PSN) offers total cathodic protection services ranging from simple sacrificial anodes to highly sophisticated, automatic impressed current schemes using precious metal coated anodes and computer assisted monitoring and control techniques. Our services include:

•    Feasibility studies and site investigations
•    System planning, design, consultancy and management
•    Supervision on installation
•    Supply of equipment including:
•    Anodes (particularly Anodes with precious metals coating: MMO and Pt/Ti)
•    Transformer rectifier units (constant current, constant voltage, auto-potential)
•    Reference electrodes
•    Other cathodic protection equipment (Junction boxes, cable, joints, thermit weld)
•    Installation
•    Inspection and troubleshooting
•    Preventive and general maintenance

At PSN, cathodic protection systems are engineered for a wide variety of structures including:

•    Power stations, Refineries and petrochemical complexes
•    Reinforced Concrete structures
•    Harbors, Jetties, platforms and other marine structures
•    Below and above grade storage tank internals and externals
•    Pipelines
•    Well Casing

Cathodic protection remote monitoring and control systems
Application of cathodic protection remote monitoring and control systems provides access to valuable data on the condition of a CP system without the need to send an operator to site. Through application of these systems, fewer operators will be required as well as fewer visits to site.

Some major capabilities and advantages of the cathodic protection remote monitoring and control systems are as follow:

•    Controlling, measuring, data logging of Transformers rectifier current and voltage outputs and the structure to electrolyte potential data measured by embedded reference electrodes.
•    Remote access to the system through internet access
•    Alarm systems to warn of any fault in cathodic protection systems
•    Remotely On/Off system of the cathodic protection systems
•    Remotely carry out Depolarization and Instant off test routines
•    Automatically adjusting current and voltage output of the transformer/rectifier
•    Data acquisition and reporting at operator specified intervals either manually or automatically at pre-scheduled intervals.
•    Operator friendly supervisor software with on screen dynamic graphic display
•    Repeatability of accurate readings
•    Reporting and representing the information in various formats such as charts, tables, and sending them through Internet

Corrosion Monitoring

Without an accurate assessment of the corrosion condition and rate, achievement of a corrosion control program will not be possible. By offering corrosion monitoring services, we examine areas susceptible to corrosion and measure its rate in order to improve corrosion management and control program strategies.

Payesh Sanat Novin corrosion monitoring services are as follow:
•    Design of corrosion monitoring systems
•    Supply of corrosion measurement and monitoring equipment including:
•    Weight loss coupons
•    Electrical resistance probes
•    Linear polarization probes
•    Hydrogen probes
•    Galvanic probes
•    Microbiological corrosion monitoring systems
•    Sand detection and erosion monitoring systems
•    Installation of corrosion monitoring fittings and equipment including probes and coupons insertion and retrieval
•    Corrosion monitoring data logging, processing, interpretation and process modification consultancy
•   Correlation of corrosion monitoring results and chemical treatment in order to optimize treatment cost and efficiency
