Instruments for inspection and maintenance of the cathodic protection system. Permanent and portable reference electrodes. Reference electrodes are devices which are indispensable in cathodic protection technology. It is using these devices that the potential of a structure relative to its medium is measured, so that the condition of the metallic material is evaluated, that is, corrosion presence is determined, if the structure is protected or if there is influence of interference currents. The copper/copper sulphate electrode is used mainly for measuring soil potentials, and its use in liquid medium should be avoided. The silver/silver chloride electrode is specific for salt water. The zinc electrode can be used both to measure a potential in salt water and in the ground. For use in the soil the zinc must be wrapped in a plaster and bentonite conducting filling. Each reference electrode has a different value for its own potential. That is why potential data measured by different reference electrodes shows different values. Holiday Detector A detector that discovers flaws in the coating through electrical inspection. Advantages of the APS model APS: - Safety lock, prevents shocks. - Two batteries - High and low voltages in the same piece of equipment. - Durability

Flexpipe Systems, a subsidiary of the ShawCor, produces and trades a flexible pipeline composite system provided in spools to use wherever high pressure and corrosion resistant pipelines are needed. Applications Exploration and Oil and Gas Transportation ONSHORE Production Well Collection Lines Water disposal CO2 injection lines / water injection lines ONSHORE Production Well collection lines Applications where corrosion resistant pipelines are needed. The Installation Solution The pipes of the Flexpipe Systems can be installed in several ways: open-air ditch, non-destructive methods, aerial lines or insertion of pipes in deteriorated steel lines. Flexible, continuous and supplied in spools, Flexpipe Systems pipes and their highly reliable coupling systems allow quick assembly, which results in less line assembly time, and a considerable reduction in the installation costs. The Economic Solution The pipes of the Flexpipe Systems are a solution with a highly competitive cost. A tractor-trailer can transport up to 6km of spools at once, which represents a considerable reduction in the transportation and handling costs of the product, which is very light. Since the pipe is supplied in very long spools, the number of connections is much lower than with the pipes individually supplied, which are 12m long. The connections, entirely cold installed, do not need welds or inspection. The Environmentally Friendly Solution The pipes of the Flexpipe Systems can be installed through a constructive method that requires a narrower easement and less equipment than the conventional metallic pipes. Flexpipe markedly reduces the environmental impact and allows the end-user to keep a good relationship with the landowners. The Solution for Corrosion The patented design of a Flexpipe three-layered composite allows a service life expectancy of 50 years, and is completely immune to corrosion. The immunity to the corrosion eliminates the possibility of leaks and spills associated with the deterioration of conventional metallic pipes. Once installed, Flexpipe allows great economy in operation and maintenance of the pipelines, because it is immune to corrosion. That eliminates the need for corrosion inhibition programs, cathodic protection systems, inspection and maintenance of the external coating, periodic inspections of the pipes with smart pigs, and avoids changing corroded pipes or applying reinforcements with brackets or other repair methods. The Solution for Safety Flexpipe Systems is committed to guarantee a safe work environment for all its employees, clients and service providers. Flexpipe Systems ensures that the unions used to connect the pipes are extremely safe because they are cold-installed. The pipes by Flexpipe Systems require smaller field installation teams and less equipment, reducing the risk of accidents. All the Flexpipe Systems activities are carried out according to the HSE laws (health, safety and environmental protection at work). Standards The pipes manufactured by Flexpipe Systems are made according to the following standards: - ASTM F2686-10: The Flexpipe Linepipe pipes meet the international ASTM standards as defined in the \"Standard Specification for Thermoplastic Pipes Reinforced with fiberglass\". - ISO 9001:2008 : Flexpipe Systems is certified for complying with the \"Quality Management System: Requirements\". - ASME: Flexipe flanges are according to the requirements by ASME b 16.5, \"Pipe Flanges and flanged fittings\".

PIPESAK pipeline mooring systems. The Pipesak geotextile ballasts represent a modern option for the clients that design and build pipelines. The genuine woven PipeSak ballasts can be quickly filled in the work site or near it, to be easily installed, and will have a longer service life than the one of the pipeline itself. The PipeSak ballasts are installed on the pipeline after it is laid down in the ditch. The pipe is taken to the work site, welded and lowered to its position, as usual. With PipeSak ballasts the client gets a product that does not undergo biodegradation; it uses the natural gravel found around the work site as ballast; it prevents aggression to the coating and the pipeline; it limits blocking the cathodic protection system and reduces the project\'s costs. Easy Installation The PipeSak, floatability control, is designed to be filled with natural and local aggregate (the ballast itself) using an especially developed system to fill and remove the gravel quickly through a bucket/funnel system. It can fill the bags in any area where a certain quantity of gravel can be accumulated. . There is no need to remove water from the ditch or to make it deeper. . Once installed, the PipeSak ballasts will never slip down the pipeline. The PipeSak has several advantages, concerning corrosion, over other counterweights for floatability control. . There are no spaces between the Pipesak and the pipeline, which prevents accumulation of soil particles, which may damage the pipeline coating while the ditch is being refilled. . Pipesaks are soft, reducing any risk of damage to the coating or the pipeline during installation. . Pipesak ballasts do not contain metal components that may rust or damage the pipeline. . There are no obstacles to the cathodic protection because the porous material of the Pipesak offers easy passage for the electric currents from the cathodic protection. PIPEPILLO piping support Pipesak has developed the PipePillo®, that, when piled, serves as a support for the piping, raising the pipes beside the ditch at an ideal height for the welding, surface preparation and blanket application. A proper replacement for the \"bonfires\", made of wood and built in the field, the PipePillo is environmentally correct and economically more feasible, because it can be reused in different work sites and even in other projects, for pipes of up to three different diameters.

Italian company that makes monoblock electric insulation joints used to insulate the pipeline from structures to which no cathodic protection will be applied, such as grounding, foundations and supports. The results are: – To electrically insulate a protected structure from another structure, avoiding that the current reaches the structure which no electric current is to reach; – To divide a structure to be protected into isolated parts and treat each part in a different way. In certain circumstances, such procedure facilitates the protection. They show more advantages in relation to the conventional joints because they are much more resistant to flaws and leakages. They are manufactured and assembled under controlled processes that offer monolithic joints a bigger capacity to support elevated pressures and aggressive fluid conditions, and DO NOT REQUIRE MAINTENANCE. The limitations of the conventional insulating joints (of the flange kind) are the following: – A small misalignment of the flanges causes crushing of the cartridge that involves the bolt, resulting in insulation loss; – The movement of the piping itself, due to thermal expansion, can cause insulation failure. - A good installation depends on the installer; - They need maintenance. The Projoint Joints are prefabricated and supplied with a small segment of piping. They are inserted into the tubing, and their extremities are made of steel and welded to the pipe. In the specification of the joints should be evident: – Line pressure rating; – Tubing Nominal Diameter; – Nature of the fluid transported; – Working Temperature; - Wall Temperature.

Metal Samples offers probes and inside corrosion monitoring including: metal loss coupons, coupons supports, access devices, tools to insert and remove coupons and probes, electric resistance probes (ER) and linear polarization resistance (LPR), biological probes and special technique probes, instrumentation to measure probes among others. But what is corrosion monitoring? Corrosion monitoring is the practice of measuring the corrosivity of a processed fluid or the degradation of the material through the use of corrosion probes or corrosimetric probes, and chemical and microbiological analysis. The probes or testers are inserted or connected to the equipment and are continually exposed to the process flow conditions. There is a series of corrosion monitoring techniques which are used in corrosion engineering, among which, some may be followed online through constant process monitoring, while others can be determined through a laboratory analysis. Two of those monitoring techniques deserve highlighting: the one that uses metal loss corrosion coupons and electric resistance. None of the techniques are electrochemical and both are summarized below. Corrosion Coupon (metal loss) The metal loss corrosion coupons provide in a direct and simple way the corrosion rates of lines and equipment manufactured in carbon steel or other materials. Their methodology is relatively inexpensive and they provide reliable data for a certain period of exposure, in addition to information about corrosion morphology. The basic procedure consists of using a test sample (a coupon) or alloy according to the equipment material and place it so that it will be exposed to the same electrolyte or medium of the equipment that the client desires to assess. After a predetermined time period, the coupon is removed from the process, cleaned so that all the corrosion product is removed and weighted. The metal loss is converted into corrosion average rate, according to the following formula (ANSI NBR 6210:2008) : , Where: rcorr = rate of corrosion expressed in the desired unit (see Table 1) k = constant that depends on the desired unit (see Table 1) W = metal loss, expressed in grams (g) - mi-mf A = test sample exposed area (cm2) t = exposure time (hours) d = metal or alloy density (g/cm3) NOTE: The areas covered by the support and insulator should be excluded Table 1 – Factor of conversion (k) for the expression of the corrosion rate Expression Conversion Factor (k) Thousandth of inch per year [mpy] 3.45 x106 Millimeter per year [mm/year] 8.76 x104 Micrometer per year [µm/year] 8.76 x107 Gram per square meter per hour (g/m2.h) 1.00 x104 x d Milligram by square decimeter per day [mdd] 2.40 x104 x d Microgram per square meter per second [µg/(m2.s)] 2.78 x106 x d NOTICE: d = density of the metal or alloy The complete procedure of preparation, cleaning and determination of the rate of corrosion is described in the ANSI NBR 6210 standard: 2008. One of the main advantages of that approach in the determination of the rate of corrosion is that we will be able to identify the morphology of the corrosion, that is, whether it is uniform or local, and in addition we will get the real thickness loss in the exposure time period. Another advantage is that this technique is applicable to virtually all environments, such as the gaseous, the liquid and the ones that involve flow of solid particles. A disadvantage of this method is that these data are a history, and as such they provide information on past performance; therefore they cannot provide short term data or quick answers. Monitoring Electric Resistance (ER) Electric resistance probes can be considered automatic metal loss probes, providing continuous metal loss data. Continuous monitoring with electric resistance probes provides a trend followed by the corrosion rate against time, allowing clear identification of the periods of increase or reduction of the corrosivity of the medium associated with the variables of the process such as flow rate, temperature, pressure, concentration variation etc. In spite of that, they cannot show corrosivity changes in the fluids or corrosion rates in short periods of time. The technique through which corrosion rate is measured is applied from the area variation, caused by the corrosion of the cross section of the sensor element (probe) exposed to the medium which causes the variation in the electrical resistance of this sensor. The stress of the exposed area causes the cross section of the sensor to shrink, and therefore the section loss causes the electric resistance of the metal to vary. This approach is based on the following equation: ? Where: R = Resistance (ohm) = resistivity of the material (ohm.cm) L = Length (cm) A = Area of the cross section (cm2) The variations of electric resistance are measured cumulatively along time, having as a base the initial measure of the sensor. Actually, the equipment used converts the resistance into section loss of the sensor element automatically, and this measurement is based on uniform corrosion. The electric resistance probe can be used in any kind of medium to determine the uniform corrosion rate, but its results are only meaningful for the average of mass loss of the sensor, and it is not possible to read the instant corrosion rate. Data can be collected in the following ways: Manual collection on site: The collected data can be stored in a data collection station (logger) for subsequent retrieval of the information; Transmitted online, via satellite, radio or any other way of transmission. As one of the main advantages of the approach, we can mention that this technique is sensitive to the operating changes and flow regime, as long as they do not take place in a too short interval of time and, in addition to that, through the profile of the corrosion rate, we can modify the process variables to reduce corrosion. Its main disadvantage is the fact that the method is not very sensitive to localized corrosion. Monitoring Linear Polarization Resistance (LPR) The Linear Polarization Resistance method is based on principles and electrochemical concepts. The electrodes at the tip of the LPR sensors (two or three electrodes) are polarized in short intervals of time and as an answer to this polarization we have he corrosion rate in real time for the electrolyte, or medium under analysis. The Measurement principle of this technique is valid, because the current density associated to small polarization effects is directly proportional to the corrosion rate of the electrode in the medium that is being observed. The main advantage of that technique is that we have a corrosion technique in real time and its main limitation is that the electrochemical principles that are applied in this technique are for uniform corrosion. If pitting corrosion is still present, the values will be distorted and not real.

Supplies decouplers that drain alternated current and block direct current. Main applications: • Insulating Joint Protection: Installed parallel to the joints, the decouplers allow passage of AC currents from lightning bolts or high voltage lines in case of short circuits or continuous regime. • Mitigation of AC voltages from high voltage lines. • The best way to reduce those voltages is to ground the pipelines but this would render the cathodic protection useless. The decouplers allow connecting the pipelines to the grounding without deactivating the cathodic protection because they drain the AC currents and block the DC current. • Grounding of valves and stations connected to the pipelines. • Tank grounding with cathodic protection. • Temporary grounding of ships in ports.

The anodes in impressed current systems can be installed in the most diverse configurations, according to the kind of structure. In maritime installations, the anodes hang between the structures or stay at the bottom of the sea, or, yet, fixed on the structure itself, on a special device. Iron-Silicon-Chrome anodes for impressed current cathodic protection. Anotec Anodes are used to provide electric current through soil and natural waters so structures are protected through corrosion mitigation. During the process, the anodes are slowly consumed. The Anodes used in impressed current system differ fundamentally from the galvanic anodes because they are inert, and consequently are wear-resistant and have a longer life. The main characteristics are: . Density of the admissible current The density of admissible current is included in the characteristic data of the kind of material used in manufacturing. The use of a current density above the recommended maximum can cause extreme and irregular wear to the anode. In certain cases, it can cause insulating products to appear on the surface. . Anode Wear Each kind of anode has a known wear rate, whenever it operates within the maximum current density level. The rate of stress of a certain kind of anode needs to be considered for the calculation of its life. In general, the bed is designed for a minimum life from 15 to 20 years. . Size The electric contact resistance between the node and the electrolyte is a function of the size of the anode and the resistivity of the electrolyte. Therefore, once the installation is defined, the resistance of each anode will depend on its size. An addition in the length or in the diameter of the anode will result in a reduction of the resistance; however, the influence of the length is well over that of the diameter. The total resistance of the anode bed when applied in soils with average to high resistivity is, in general, the factor that defines the number of anodes to be employed. The iron, silicon, and chrome anodes (Fe-Si-Cr) are manufactured in circular bars, through foundry, with silicon content of 16% and chrome content of at least 4%. They are recommended for soils, sea water, sea bottom and fresh water.
