How do you test a cathodic protection system?
Connect a copper sulfate half-cell to your volt meter and make contact with the ground, while connecting your meter to underground metal. Afterwards, measure the pipe to soil voltage potential. Your readings should be 0.85 or higher. Measurements lower than 0.80 is indicative of corrosion.
What is CP in pipeline?
Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathodic side of an electrochemical cell. Cathodic protection systems are used to protect a wide range of metallic structures in various environments. The most common applications include: Water and fuel pipelines.
What is a natural gas test station?
A test station is a specific type of test point that is accessible from aboveground, installed in a test box, and has terminals for electrical connection to the steel pipe. 1.3 Installation of CP test points on natural gas mains must meet the Code of Federal Regulations. (CFR) Title 49, Part 192.469.
What is a CP test station?
A cathodic protection test station is an integral part of any pipeline cathodic protection system. The cathodic protection test stations can be supplied as a kit with the cabling, reference electrodes and thermite weld equipment needed to complete the installation. MATCOR’s mission is to solve your corrosion problems.
What is a cathodic protection rectifier?
Cathodic protection rectifiers are the external power source used in impressed current cathodic protection systems (ICCP) to convert alternating current (AC) to direct current (DC). In ICCP systems, current is discharged off of the anode and onto the structure to prevent corrosion.
What is a good CP reading?
During a CP inspection, the crew expects that a range from -700mV to -1300mV will be observed for a pipeline or structure’s potentials and anything more negative than -800 mV is “good.” What is often overlooked is that a CP inspection system can be influenced by a number of factors including: trailing wire or deck lead …
What are CP stations?
A cathodic protection test station is an integral part of any pipeline cathodic protection system. Cathodic protection test stations are an integral part of any pipeline cathodic protection system.
How much pressure is in a residential gas line?
The natural gas pressure of the gas line leading to the home ranges from approximately 1/4 psi to 60 psi, depending on the number of homes or businesses served by the line. This compares to pressures of up to 1,500 psi for large-volume pipelines used to move the gas from the well fields to the local utilities.
What does blood CP mean?
CP – serum; Copper – ceruloplasmin. The ceruloplasmin test measures the level of the copper-containing protein ceruloplasmin in the blood.
What is Disbondment?
Disbondment is a type of corrosion protection involving metals in which a loss of adherence between metal substrates and cathodic coating occur due to a reduction reaction in the coating’s interface. Typically, systems for cathodic protection are installed to support coating imperfections.
