RSRTENG Tips
Technical Toolboxes receives many RSTRENG questions throughout the year; however, most of them are not related to operating the software. These questions are related to procedures, definitions, and field repairs.
When metal loss features in pipelines are detected by in-line inspection (ILI), a decision to replace, repair, and assess remaining features. This decision is based on the prediction of the failure pressure of the corroded pipeline and must adhere to the US Code of Federal Regulations (CFR) Title 49, Parts 192 and 195, that stipulates that ASME B31G or RSTRENG be used to assess the remaining strength of corroded pipelines.

RSTRENG (Effective Area) Calculations
What Actions must be Taken to Address Integrity Issues?
According to DOT 192.933 a calculation of the remaining strength of the pipe shows a predicted failure pressure less than or equal to 1.1 times the maximum allowable operating pressure at the location of the anomaly. Suitable remaining strength calculation methods include, ASME/ANSI B31G; RSTRENG; or an alternative equivalent method of remaining strength calculation. Check Out

Preventative and Corrective Measures to Control Corrosion Pitting
A corrosion rate needed to set the re-inspection interval, reassess the performance metrics and their current applicability, plus to ensure the assumptions made are correct. At each direct examination where corrosion pitting is found, the operator should measure and record each pitting cluster. The aforementioned data are then used to estimate corrosion rates. Average corrosion rates are related to the environment, depth of pitting and years of in-service. Check Out
-
Estimating Internal Corrosion Rates?
Internal corrosion is most likely to occur where water first accumulates. Predicting these locations of water accumulation serve as a method for prioritizing local examinations. Predicting where water first accumulates requires knowledge about the multiphase flow behavior in the pipe requiring certain data. The following are some general calculations based on flow conditions. Keep in mind that these are strictly estimates and do not consider the effects of temperature, wettability, MIC, pressure, hydrocarbon characterization, gas composition, etc. Check Out
-
Estimating External Corrosion Rates?
All corrosion defects found during each direct examination should be measured, documented, and remediated as needed. At each excavation, the pipeline operator should measure and record generic environmental characteristics (such as soil resistivity, hydrology, drainage etc.). These data have been used to estimate corrosion rates. Average corrosion rates related to soil resistivity are below in the following table with no CP. Check Out

ASME B31G Original/Modified and RSTRENG Overview
ASME B31.G Original and Modified (0.85) are Level 1 assessment along with most other metal loss calculations that are limited to pits and short lengths of pitting clusters. Check Out
