Using Guided Waves Testing (GWT) for the Integrity Inspection of Pipelines

Product Number: 51324-20599-SG

Since its commercial launching, guided wave testing (GWT), a.k.a. long-range ultrasonic testing (LRUT), has been largely applied in the oil and gas industry for the inspection of pipelines, due to its faculty for screening large lengths of pipeline from a single point of contact. This capability has made the GWT one of the “other technologies” most employed in the integrity inspection of pipelines; however, regardless of its broad usage, industry standards guiding the integrity management of pipelines do not provide a clear framework for the use of GWT, neither do they agree on the role that it plays in the integrity assessment process. For example, some standards classify the GWT as a standalone corrosion integrity assessment method, while others reference it as an inspection technique, and others allocate it as a corrosion monitoring technique. This paper makes a comprehensive review of the involvement of the GWT in the pipeline’s integrity management process and intends to provide a clear framework for the use of guided wave testing (GWT) as an integrity inspection method for pipelines.

Using Lead Abatement Contractors for Surface Preparation on Commercial Properties - The Consequences of Sacrificing Quality for Safety

Product Number: 51216-012-SG

Author: Raymond S. Tombaugh

Publication Date: 2016

$20.00

The Federal EPA requires that commercial/residential painting contractors be certified to prepare surfaces containing lead based paint on residential and public structures. As a result, when respirators equipped with HEPA filtration are required to be worn to reduce worker exposure levels to below the permissible exposure limit for lead, the surface preparation work is often subcontracted to a licensed lead abate contractor who holds these types of certifications.

Using Machine Learning to Assess Internal Corrosion Constituent Thresholds

Natural gas pipeline operators often rely on gas and liquid sample analysis as well as bacteria serial dilution to determine if corrosive conditions exist within the pipeline. When corrosive conditions are suspected, additional monitoring methods such as corrosion coupons or probes are employed. One of the challenges faced by operators is determining what constitutes “corrosive conditions” because existing regulations do not define gas or liquid compositions that are corrosive. In this study, over a decade’s worth of sampling and corrosion monitoring data collected by a natural gas pipeline operator are assessed using machine learning in order to determine the parameters with the greatest influence on corrosion rate. This work combines over 2,300 gas tests, liquid samples, solid samples, and bacteria tests in an attempt to determine if the thresholds the company is using are reflective of where corrosion is actually occurring based on over 1,700 coupon analysis results within an operator’s unique system. The results from this study can be used to guide future sampling practices so that effort is spent collecting the most meaningful data and improving the ability to identify corrosive conditions.

Using Robotic Inspection for Flare System to Avoid Plant Shutdown

Product Number: MPWT19-14300

Author: Amro Hassanein

Publication Date: 2019

$0.00

From day to day, Robots advance from testing in labs to operating in the outside world. The
industrial application of Robotic technologies continually increases, providing unique solutions for
different challenges. Flare System is an important and critical equipment required for continuous
safe operations for any petrochemical plant addressing proper burning of excess hydrocarbon
gases, unusable gases which cannot be recovered or recycled, and gas flaring protects against
the dangers of over-pressure. This paper discusses the different types of robotic inspection,
advantages, and limitations based on actual site demonstrations. As an innovative case, here to
introduce actual business case for close aerial inspection and surveying technique to avoid
polyethylene plant shutdown and providing a reliable inspection technique for on-stream integrity
evaluation for the flare tip. Drones, formally known as unmanned aerial vehicles (UAVs), are a
flying robot that can be remotely controlled, and offer an innovative inspection method launched
between 2006-2008 for Engineering professional aerial inspection and surveying using Remotely
Operated Aerial Vehicles (ROAVs). The visual inspection detection accuracy of (ROAV) offer
higher than the normal visual inspection and easily approach all the flare structure from four
directions. Drone inspection cost is competitive considering the cost of maintenance to dismantle
the flare tip. Drone inspection can be used to assess the elevated flare parts for any seriously
damage in order to define a clear maintenance scope ahead of shutdown.

Using Simulation to Understand the Difference Between Corrosion in Atmospheric Environments and Chamber Tests

Product Number: 51319-13242-SG

Author: Alan Rose

Publication Date: 2019

Corrosion in the field manifests over a large timescale so when considering material choices in the design of aerospace systems and subsystems use is often made of accelerated tests such as ASTM B117 salt spray chamber test to rank the possible materials. Even these ‘accelerated’ tests take more than 1000 hours and despite their widespread use are often criticized as a design trade tool since the test environments are considerably different to the expected field environment running the risk of either hiding true corrosion processes or simply being unrealistically challenging for the materials under test.The corrosion community has expended substantial effort in trying to make the tests ‘more realistic’ but in doing so there is considerable debate about whether the tools employed to accelerate the corrosion (thermal cycling high salt concentrations UV exposure etc) actually introduce other corrosion processes that are not even present in the eventual targeted field of operation for the device under test.Computational techniques hold a great deal of promise as a way to understand the effects of different service environments but if the simulations cannot even discern between say an ASTM B117 test and an atmospheric exposure then the simulation results would be of questionable value.The processes involved in corrosion are many and complex however one key parameter is the electrolyte film thickness which will clearly be different whether inside a chamber at high humidity with a continuous supply of sprayed saltwater compared to exposure on a beach where diurnal cycles result in a very thin electrolyte of varying salt concentrations except of course when it is raining!To help designers quickly assess corrosion risk and choose appropriate materials Corrdesa have already developed an electrochemical database of modern alloys and coatings. This has been extended by deconvoluting the polarization data to accurately account for the impact of the actual electrolyte thickness on the oxygen reduction reaction.In this paper using fluid shell elements in a free surface flow formulation we actually predict the variable electrolyte film thickness in a CFD (Computational Fluid Dynamics) code for a given environmental condition on different test specimens and geometries. The appropriate polarization data for the local electrolyte thickness is then implemented with User Functions in a potential model framework. In this way the galvanic corrosion is simulated for a test device with a more realistic and variable film thickness.The result is that we can dial different test conditions into the simulation such as whether we wish to simulate chamber results or field results cyclic salt fog cyclic humidity (or both).Keywords: Computational Corrosion Analysis Galvanic corrosion prediction FEA corrosion prediction polarization data potential model fluid shell elements CFD

Volatile Corrosion Inhibitor (VCI) packaging has wide acceptance in the logistics world as an effective means for the protection of metal fabricated parts during shipping and storage. The utilization of VCI packaging for metals other than steel is still a challenge. Customers are reliant on packaging suppliers to provide them with a technical solution to their unique parts yet there are no standard test methods to prove that their offering is going to work for their alloy or part. This paper discusses the application of the well-understood, TL8135-002 Vapor Inhibiting Ability (VIA) test on a variety of non-steel specimens, including copper, brass, zinc, and aluminum.
