The Electronic Corrosion Engineer (ECE) Version 5.0 5.0.1 .1 September 2012 Disclaimer :
Materials and Corrosion Engineering is (not yet) an exact science. The information and model predictions contained in this program is claimed to to be be “state of the art”, art”, but but no responsibility is accepted for damages from, or related to, its use. The Electronic Corrosion Engineer is a tool for the corrosion or materials engineer to evaluate some important aspects of corrosion control and materials selection. It is intended for use use by by an engineer who understands the significance of the input data and how to apply the output data. ECE is not an expert system or a replacement for a corrosion engineer. Copyright : Intetech Ltd.

Scope of the Ele Electro ctro nic Corro sion Engi nee neer r
Previous Top Next
The ECE is principally concerned with material selection for two key capital expenditure items in oil and gas developments: downhole production tubing and flowlines. The aim is to propose a safe material selection at minimum cost . The evaluations are carried out independently for the two types of products using the tools available from either the dropdown menus or from the icon icon bar. bar.

ECE provides the following tools: Tubing Corrosion Predictor Flowline Corrosion Predictor Analysis of the potential corrosion rate of carbon steel under the given conditions, together with an evaluation of the risk of failure of carbon steel based on the estimated corrosion rate and given tubing/flowline wall thickness. Tubing CRA Evaluation Flowline CRA Evaluation Evaluation of the suitability of various CRAs for the given conditions; selecting those that will not fail by either localized or general corrosion, or by cracking. Tubing Life Cycle Calculation Flowline Life Cycle Calculation Life Cycle Cost (LCC) evaluation of selected CRAs compared to carbon steel. Tubing CRA Manufacturers Flowline CRA Manufacturers Check on the possible sources of the selected CRA. The Tubing tools deal principally with vertical flow, although deviated tubing can also be modeled. The Flowline tools deals exclusively with horizontal flow.The orientation has a significant influence on the flow regime which impacts on some aspects of the corrosion rate, such as the likelihood of having erosion of corrosion product scales or separation of water from oil. The tools can be used independently so that the evaluation of the carbon steel corrosion rate and the risk of carbon steel failure can be carried out without any reference to the evaluation of suitable CRAs, their sources and the LCC comparison between the CRA and carbon steel options. Similarly, the CRA evaluation or check on suppliers of a given type of CRA can be done without first checking the potential carbon steel corrosion rate. ECE can be used to estimate the corrosion rate in facilities and top‐side pipework. In such cases the pipe diameters are generally known but flow rates are not known and may be very variable, as may the flow regime. In such cases the oil and gas throughput may be set to nil and the water throughput adjusted to give a liquid flow velocity (see “Details” tab) of 1m/s in the pipe diameter required. This reflects a reasonable average engineering flow condition.

Demonstration Version
A demonstration version of the current software can be downloaded from the INTETECH website to allow potential users to explore the capabilities of ECE. The demonstration version has a time‐limited licence and certain functionality is restricted. Full Licensed Versions
When a user purchases a full license, INTETECH provide the license codes necessary to upgrade the demo version to a fully functional licensed version. The ECE software is available as a stand‐alone program for a single computer, under a single user licence. A multi‐user version of the software is also available to run on a network server, allowing multiple concurrent users. This Multi‐User version is supplied with a separate licence available from Intetech Ltd. Contact:
[email protected] Transferring a License to Another Machine
ECE 5 includes a License Transfer wizard that offers a step by step procedure to users in order to ensure the process run smoothly. Note that is required to create a license file on the intended destination machine at the start of the license transfer process however the wizard will prompt this on startup.
