I can't answer call now. I am in control medical exams You sent Chat later 17 Sep 2021, 11:01 You sent Hi Luis, Thank you for your interesting question well explained and drawn. Please have a look at the following link. .... http://www.pipeline-corrosion-control.com/InsulationJoints/ The use of a 12 volt battery in testing Insulation Joints and flanges is frowned upon as it could cause a spark across any weak insulation and damage the insulation. Your resistance in series would mitigate this effect. The problem remains to find where the CP current is going to. The easiest way is to use two ground contact electrodes (half-cells) and conduct a grid survey over the whole area including the concrete surfaces after wetting them. This procedure is described in detail at the following link ... http://www.pipeline-corrosion-control.com/ProcHTML/DCVG/index.htm I can answer any further questions on messenger with diagrams and videos chats Roger On 16 September 2021 at 23:51 Luis Rebolledo - Gerencia Procatodica wrote: Mrs Roger Alexander It is my pleasure to contact you. I am submitting to you electric diagram and pictures the last four tests done in order to determine the electrical resistance of four insulated flanges, type E 12 inches in diameter, 300 ANSI. These are three short sections of pipes with Fusion Bonded Epoxy coating, which have a high consumption of cathodic protection current and the Instant Off potentials do not reach the criterion of -850 millivolts polarized. Using our equipment Insulator tester RF / IT, we find that most of the asparagus are electrically well insulated. In all tests, we used a battery (12 volts 7 amps) and an external resistor (2000 watts 4 ohms) in series. I would like to know if you consider the tests carried out to be valid or to be satisfactory to you. Cordialmente, Luis Rebolledo Martinez Gerente Procatódica de la Costa Ltda. Calle 69F No. 41-192.

You sent and on what basis? Luis Luis Rebolledo our client is the one who establishes the protection criteria You sent and I expect he gets it from the USA.... eventually NACE You sent and NACE refers to API who refer to NACE Luis Because, the Crude oil transportation pipelines operate with temperatures greater than 100 degrees Celsius Luis Luis Rebolledo It is a congested field of pipes You sent yes..... this is why you need to use science and not guesswork You sent Luis Luis Rebolledo I agree You sent You sent Luis Luis Rebolledo You sent You sent yours is an excellent drawing of a small section You sent I suggest you look at the following video https://www.youtube.com/watch?v=c0qlBZBl_94&list=PLkZ9d2GdNjnCMhe8grTzTm6AFW8DmTwUn&index=1 Luis Luis Rebolledo Ours presentations are copied from of your publications You sent very good.... thanks You sent this demonstration of how cathodic protection works will help you gain credence because it is pure science in action that you can set up yourself at very small expense.

A Las probetas de arriba se les debe rellenar con muestra propia del suelo. La ALCE debe colocarse en cercanías a un test post y realizar conexión directa entre la tubería y una probeta; interpreto que exponiendo las probetas a la IPC distribuida en el electrolito y colocando un micro amperímetro DC en mitad de una probeta superior y una inferior, es posible medir e identificar dirección de la corriente de PC que circula entre las probetas que se comportan como ánodo a cátodo. Supongo que en algún momento sería útil para determinar si el cátodo protegido está recibiendo adecuada PC o descargando corriente al suelo. La interrogante es contra que se compara la cantidad de corriente en microamperes que se logre medir. Interpreto que el procedimiento de ALCE en campo consiste en: 1. Colocar ALCE semienterrada en cercanías a un test post 2. Conectar el micro amperímetro en los bornes identificados con bornes (+ y -) 3. Medir corriente (microamperios o miliamperios) entre ánodo y cátodo sin conexión a la tubería que está siendo protegida con SPC permanentemente. 4. Conectar ALCE a la estación de prueba cercana. 5. Medir y registrar la corriente DC que se drena a la tubería enterrada y protegida catódicamente 6. Comparar la corriente inicial (miliamperios) con la corriente que se obtiene al momento de integrar ALCE al SPC permanente Conclusión: Si la corriente que se mide con ALCE es mayor a la corriente inicial, entonces se puede inferir que en ese punto la PC aplicada, ha detenido la Icorr 23 Oct 2021, 17:35 You sent Gracias Luis Su explicación es correcta, pero se refiere a los cuatro cupones como tubos de ensayo y esto puede ser engañoso. Se utiliza el término 'cupones' para referirse a muestras del metal sujeto que se colocan en un bloque de resina epoxi eléctricamente resistente. Los dos cupones inferiores se pulen antes de cada uso para que tengan la misma reacción de corrosión al electrolito / tierra con el que entran en contacto. El ánodo de esta celda de corrosión se crea puliendo la parte superior del cupón que está conectado al cupón base debajo de él. El otro cupón superior nunca se pule, sino que se lava después de cada uso para que los productos corrosivos permanezcan en su lugar. Es un hecho bien establecido que el acero pulido actuará como un ánodo del acero sin pulir y esto se demuestra en el primer paso en la prueba de Alexander Cell. La lectura del microamperímetro en la primera parte de la prueba también prueba el valor de la corriente de corrosión que se crea por esta área fija de contacto con la muestra de electrolito que une el ánodo y el cátodo de este sistema. El área conocida de contacto de los cupones base nos permite medir con precisión la "densidad de corriente" de la corriente ICCP en esta ubicación. El pH, la temperatura y la presión en el momento de la prueba afectan cada medición registrada. La segunda parte de la prueba es conectar el cupón base debajo del ánodo a la tubería o al metal sujeto. Esto convierte a la celda de Alexander en una celda de corrosión en la superficie de la tubería, además de las otras celdas de corrosión que ya podrían estar presentes. La medida que se muestra en el microamperímetro es la dirección y la magnitud de la corriente de corrosión en la celda Alexander cuando está influenciada por la energía eléctrica presente en esta ubicación en este momento.

ALEXANDER ROGER 13:56 To hamedyorc@gmail.com Quick replyReply allForwardDelete Dear Hamed, By this email I confirm that you are now the coordinator for Cathodic Protection Network, Yemen and that you should refer to the Facebook Group 'Cathodic Protection Network Coordinators' as our main means of communication and use Facebook Messenger as our first means of direct conversation including video chats. Please connect with the other coordinators in order to structure CPN by convention between everyone involved. As you have read in the following link we are creating a blockchain in which the protocol is computer controlled so that there can be no internal competition or conflicts. http://www.pipeline-corrosion-control.com/ActionPlan/ I suggest that you gather all local information about pipelines in Yemen, who owns them and controls them. Gather as much informatio as possible about the real cost and problems caused by corrosion and the activities that are taken to mitigate corrosion and the names of individual who are responsible for corrosion control and get them talking about their work to each other. Please read and understand the following link about the five day event that is our first goal. http://www.pipeline-corrosion-control.com/Training/MasterClasses/ This contains an outline business plan/structure that must be put in place at the highest level globally and ineach country. You will see that we need the following teams in order to scientifically control corrosion. Software development teams. Scientists at university and research centres. Corrosion engineers and designers. Field engineers and technicians. Human resources and PR specialists. A financial controller for each country. Data acquisition survey teams. Please reply to this email with your comments and questions that will be open for discussion for all participants in CPN. Remember that we are governed by the laws of the universe that have been codified over the centuries by the study of science and the scientific method. Thank you for joining us Roger 8 Nov 2021, 02:23 You sent The function of a Cathodic Protection Network Coordinator. The goal of Cathodic Protection Network (CPN) is to structure a network of specialists who carry out the activities necessary to control corrosion to networks of pipelines and facilities. We need 'Coordinators' in each country to motivate the members of each social media group to chat with each other about their experiences and expertise in corrosion control so that we have a global pool of knowledge and understanding that is not possible for one person or for one (competitive) company. A coordinator needs to connect the specialists necessary to form a network capable of working together to control corrosion. Each of these coordinators can structure the network in that country to produce cash flow for each follower of CPN technology. The way that Cathodic Protection Network functions needs structuring in the manner described in the following link http://www.pipeline-corrosion-control.com/Training/MasterClasses/ so that we can each earn cash flow resulting from our work. Coordinators are not required to share information or data but simply to introduce specialists to other specialists and to keep conversations live by spreading news about CPN science and technology. For example, professors and students in universities will chat to other professors and students globally about their studies and research projects relating to corrosion control.They will discuss sponsors and mentors as well as resources necessary to carry out their studies and the problems they are encountering. One of our coordinators has requested a business card and this is a good idea as it can be linked to this description of the function of a CPN Coordinator to make it clear how they function within the structure of the CPN I must link the card to the function of a CPN coordinator in order that the client understands how they need your service for his company benefit.. We are selling control of corrosion and we can demonstrate how we use science and technology that nobody else is offering. My own admin system must be mirrored by coordinators to ensure continuity as there are hundreds of us coordinating and synchronising our efforts for which we must be paid. I have gathered all coordinators emails into a folders for each country using the standard email system. I also have folders in the windows system for each country in which I file copies of conversations , information, pictures and data that I then convert into HTML and upload this into the relevant countries. I am very much behind in this and that is why we need webmasters to work with coordinators and the other software engineers, universities, design engineers, field engineers, technicians and survey teams who are acquiring data and information. I have no money and there is no company, we are a network of independent people who need cash flow to survive and enjoy life. For this reason we can use the blockchain structure to account for all cash flow on a distributed ledger that is on all our computers. This is the modern way to structure activities of countries and organisations. I am old and don't want or need anything, I will die soon. You guys would like a job that pays you money to carry out duties that I am now trying to define. I have no money but have knowledge and understanding that is valuable to the extremely rich in the pipeline industry. Our ideas and comments will form the protocol that will control the activities withing the CPN Blockchain. In this was we will all be in control of our individual lives and will work together in a similar way to playing a computer game.

Actualmente la tubería esta muy cerca de ánodos verticales MMO (separación menor a 5 metros) y se presenta sobreprotección catódica You sent http://www.pipeline-corrosion-control.com/00countries/SouthAfrica/comments/comments.htm Luis Mi pregunta es si es posible se presente interferencia anódica o catódica?

Esta proximidad, ocasiona que los potenciales Instant OFF registren valores electronegativos de hasta -1.286 VCSE y los potenciales ON del orden de -3.452 VCSE. Para revertir esta condición, habría que implementar medidas tales como la de apagar los sistemas de los tanques, medida que se considera inviable porque quedarían los tanques desprotegidos, o modificar la condición del Oleoducto CLM-COV de enterrado a aéreo dentro de la estación PS1. Teniendo en cuenta lo anterior, mediante ajustes en los sistemas de protección catódica y en los puenteos no fue posible modificar la condición anteriormente descrita.
