Sulfur and acidic impurities in crude oils pose serious hot oil corrosion problems in crude distillation units (CDU) and associated vacuum distillation units (VDU), especially with the increase in processing of lowquality, opportunity crudes. In the range of 200-400˚C, reactive sulfur compounds cause sulfidation corrosion of ferritic carbon and chrome steels in CDU, VDU, and front ends of downstream units operating at hot oil temperatures. Over the same temperature range, naturally occurring carboxylic acids in crudes can be so aggressive that higher alloy, austenitic stainless steels containing >2.5% Mo are required for processing high acid oils.

Due to the serious consequences of external corrosion and leaks in underground pipelines, external corrosion direct assessment, as described in AMPP SP0502, was developed to proactively prevent external corrosion and ensure the integrity of oil and gas pipelines that are difficult to pig. This standard requires a minimum of two indirect inspections to confirm the most susceptible locations on a pipeline for external corrosion to occur. Cathodic protection, coating and soil resistivity are collected during the indirect inspection process to help classify and prioritize anomalies for direct examination. This is also applicable during stress corrosion cracking direct assessment, where indirect inspection data are supplemented with other data to help pinpoint susceptible locations. All these techniques are not capable of identifying external metal loss or external stress corrosion cracks from aboveground; the pipeline must be exposed for the defects to be evaluated. The invention of the non-contact magnetic gradient tomography method has elevated DA protocols. This technology can use magnetic field strength from aboveground to identify external metal loss, cracks, dents, etc. This paper presents process improvements and real-life case studies demonstrating the benefits of this technology on non-piggable pipelines.

Automated ultrasonic testing is an integral validation tool utilized to detect defects in seamless pipes during the manufacturing process. The primary objective of AUT is to ensure newly manufactured seamless pipes are free of laminar imperfection such as non-metallic inclusions.
This paper describes the automatic ultrasonic testing (AUT) techniques capabilities applied to seamless pipe mills to detect non-metallic inclusions that could have an impact on the quality of the produced pipes. In addition, it covers all relevant applicable testing experiments applied to different sized seamless pipes by using different types of AUT machines. This paper discusses the capabilities of different static and dynamic calibration methodologies of detecting non-metallic inclusions. An assessment has been conducted on five (5) seamless pipes produced with non-metallic inclusions scattered along pipes lengths. The assessment revealed the recommended calibration and testing methodology capable of detecting non-metallic inclusion. Accordingly, a statistical analysis is presented to report the repeatability of different AUT techniques in detecting non-metallic inclusions in newly manufactured seamless pipes.

The Replica Tape method is a trusted method used by inspectors worldwide for decades to measure surface profile height. Previous studies have shown the method to be highly precise and accurate, but an intricate burnishing technique and requirement to average two different grades of replica tape in some measurement ranges made the method challenging for some users. This paper details two proposed changes to the method: an updated burnishing tool and linearized measurement scale to eliminate the need for averaging. A study was conducted to determine the accuracy and precision of this updated method, involving measurements performed by 15 users of varied experience on a range of test panels blasted with varying of media and profile heights.

Corrosion is a universal challenge for metal structures. Metal, due to its natural strength, is a common choice for building materials yet sensitive to the environment it is placed in, requiring mitigating actions to ensure proper lifecycle. Coatings are utilized as the primary defense against corrosion; the type based on substrate material and environment.

Precipitation hardened (PH) Ni-alloys are widely used in the oil and gas industry since they provide an excellent combination of corrosion resistance and mechanical strength. Their use in the manufacture of API1 6A pressure-containing and pressure-controlling components is subject to the stringent requirements of specification API Standard 6ACRA. However, matching the requirements of API Standard 6ACRA does not preclude susceptibility of some PH Ni-alloys to hydrogen embrittlement (HE) and this in some cases has led to premature and unexpected failures of components made from such
materials.(

In this paper, a case study is presented for a marine structure for which modelling has been used to predict the protection potentials over the life of the structure.

The aim of any digital transformation of integrity management and in particular corrosion control is the improvement of communication efficiency, planning efficiency and maintenance efficiency. Key issues are predictive maintenance and clarity of the information available so engineers can make informed decisions. Therefore it is not just a question of collecting more information but also the way that information is used and shared with the decision-makers.

Equipment can have an important impact on the production at a refinery, petrochemical, or chemical plant. Change of equipment will often have a negative impact since it can disrupt the production with shutdowns, which will lead to production losses. In the long term, these short lifetimes for the equipment will cause many shutdowns, which will give a higher production cost. One example of equipment is the shell-and-tube heat exchanger.

Mineral wool has been widely used for several decades as the primary thermal insulation on piping and equipment to save energy, protect personnel, and reduce emissions. The products have been favored because they are non-combustible, cost effective, provide excellent (and reliable) thermal performance and are safe, easy, and efficient to install.

Safe transportation of CO2 for carbon capture and storage requires strict control of contaminants in the captured CO2, so that corrosion and particulate matter problems are avoided. The present work tested two almost similar CO2 specifications for chemical reactions and liquid or solid drop-out. The tests were carried out with CO2 in liquid and gaseous state, at field-relevant pressure and temperatures. It was shown that the NO2 content had a strong effect on chemical reactions and tendency to drop-out, but the threshold was different depending on the physical state of the CO2. Presence of NO2 resulted in chemical reactions. Drop-outs were observed for 3 ppm-mol NO2 in the liquid state (+4°C, 100 bar) and for 8 ppm-mol in the gaseous state ( -3°C, 25 bar).
