On-Site Parameter Measurements And Corrosion Coupon Tests Of Buried Pipeline Subject To AC Interferences Of High Speed Railway

Product Number: 51322-17725-SG

Author: Le Chen, Jianjun Li, Yanxia Du, Nianpei Tian, Jia Liu, Yi Liang

Publication Date: 2022

$20.00

With the rapid development of the economy and acceleration of urban modernization, many high-speed railways and buried pipelines have been built in China. Due to the limitation of space or geographical location, high-speed railways are often constructed in parallel or crossing with long-distance pipelines in some locations. The interference of high-speed railways on pipelines is the result of inductive and conductive coupling, which brings about AC corrosion and other safety issues.

Operational Performance of RTP Flowline at Corrosive Nonassociated Sweet Gas

Product Number: MPWT19-15263

Author: Abdulhadi F. Al-Qahtani

Publication Date: 2019

$0.00

In alignment with the corporate road map, the Southern Area Gas Producing Facilities (SAGPF) of Saudi Aramco has led an initiative of replacing a traditional carbon steel flow-line with reinforced thermoplastic pipe (RTP) on a trial basis. The candidate flow-line was selected after identifying several metal loss indications via an in-line-Inspection tool. The objective of this experimental pilot was to examine the performance of nonmetallic pipeline for a conventional gas well. It is noteworthy that this trial-test is considered to be the first of its kind in Saudi Aramco —the use of RTP in a permanent flow-line installation at a conventional gas well. This technical paper will primarily discuss several important elements of the project. Firstly, it will highlight an overview on the overall corrosion damage mechanism within the conventional gas wells’ piping network and existing controlling measures. Secondly, it will highlight the advantages of this technology deployment in the oil and gas industry. Additionally, it will discuss the implementation of RTP flow-line installation, in which it will present the construction phase, commissioning, operational performance, and the successful criteria of this trial test.

Opportunistic Compilation Of ECDA, ILI, And Hydrostatic Testing For Successful Pipeline Uprating: Case Study

Product Number: 51322-17480-SG

Author: Paul S. Young

The annual natural gas demand in the United States surpassed 31 trillion cubic feet in 2019. This is over a 500% increase from demand in the 1950’s (5.7 trillion cubic feet) [1]. As gas demand continues to rise, pipeline operators have limited options to meet demand requirements. Pressure uprating is one option that can be leveraged for certain pipelines to meet the increased demand economically.

Optimisation Of Hydrogen Stress Cracking Resistance Of High Strength Precipitation Hardened Nickel Alloys

Product Number: 51322-17960-SG

Author: Stephen McCoy, Brian A. Baker, William MacDonald

Publication Date: 2022

$20.00

The Precipitation Hardenable (PH) Nickel alloys N09925, N07718, N09945, N09946 and N07725 are widely used for critical downhole oil field applications such as high strength tubing hangers and completion equipment. The materials are particularly useful in High Pressure/High Temperature wells where high strength and corrosion resistance are required in H₂S containing production fluids. Over the last 20 years a limited number of field failure investigations in PH Nickel alloys have been related to the presence of sufficient amounts of intergranular precipitates promoting hydrogen embrittlement, which results in brittle cracking of UNS alloys N07718 ^3,4 and alloy N07725⁵ and N07716⁶.

The performance of titanium mixed metal oxide (MMO-Ti) anodes — provided by five global vendors — targeted for coke breeze backfilled soil impressed current cathodic protection (ICCP) applications, was investigated in this study. The time to failure of the MMO anodes was measured in accordance with NACE TM0-108. Accelerated lifetime testing was performed on MMO anodes to measure sample durability and to adequately meet the current density design requirement (0.06A/cm2). The anodes were immersed in 1M sulfuric acid under varying current densities (1A/cm2, 1.4A/cm2 and 2A/cm2) under controlled temperature, until the samples lost their electro-catalytic properties. The results measured at 1A/cm2 illustrated that time to failure of the tested anodes ranged from 10 days to more than 90 days. While conducting the same test at 1.4A/cm2, time to failure of MMO anodes was reduced to a range of 13 days to a little over 30 days yielding results of anode ranking consistent with those measured at 1A/cm2. Therefore, for the sake of time, the optimum applied accelerated current density was recommended to be 1.4 A/cm2 for Ru/Ta MMO anodes, to push them to their limits at a faster rate in a shorter time.

Optimization of Corrosion Inhibitor Application Using Modular Automated Corrosion Control Centers

In the 1990s, military assets transported shipboard to overseas locations by the U.S. Army arrived at their destinations already corroded due to saltwater. In response to this problem, U.S. Army Tank-automotive and Armaments Command (TACOM) began manually applying spray-on corrosion inhibitor (CI) to assets prior to transportation and realized a significant reduction in corrosion. However, due to an increase in the volume of military assets being transported overseas, manual application of CI soon proved too time-consuming and costly.

Optimization of FGD Operating Conditions by Electrochemical Laboratory Testing Applied to Alloy UNS S32205

Flue gas desulfurization (FGD) systems are frequently used at power plants to remove SO2 from coal combustion. In systems where limestone is utilized, calcium sulfate from the resulting slurry can be concentrated into a valuable byproduct. However, the concentrated slurry containing chloride poses increased localized corrosion risk to the materials of construction in contact with exhaust/combustion stream. Cyclic Potentiodynamic Polarization (CPP) and Critical Crevice Temperature (CCT) present electrochemical methodologies which can be used to assess the relative risk of different conditions in the laboratory. However, the results of these techniques can be dependent on the details of the experimental protocol. In this study, the effect of slurry preparation, potential scan rate, alloy conditioning time, and slurry acidity were examined. A conservative test protocol was developed based on the outcomes of the effects considered, and the critical chloride concentration of Alloy UNS S32205 was determined, enabling optimization of FGD operating conditions.

Optimization of High Solids Self-Leveling Epoxy Floor Coatings

Product Number: 51220-280-SG

Author: Eric Ripplinger, Yanmin Zhong

Publication Date: 2020

$20.00

High solids epoxy self-leveling coatings are among the most widely used for industrial flooring due to their excellent performance, including aesthetics, durability, and chemical resistance. Epoxy self-leveling floorings are 2K systems consisting of an epoxy resin with fillers and additives and an amine based curing agent. The two part formulations are mixed and then spread over pretreated concrete surfaces, with minimal troweling or smoothing, to give excellent surface properties.

There are many factors to consider when optimizing your coating system for corrosion resistance. Waterborne coatings present a unique challenge due to their inherent hydrophilic nature and ability to readily conduct electrons. Waterborne resin technology has evolved greatly since its inception. If formulated properly one is able to meet and or exceed the performance of their solvent borne counterparts.

Corrosion resistance of low alloy steels for oil country tubular goods (OCTG) is a key point in order to select the suitable material. Among the corrosion test defined in NACE TM0177-2016, Double Cantilever Beam (DCB) testing in accordance with NACE TM0177-2016 Method D can be evaluated corrosion resistance as fracture toughness (K1ssc).

In this methodology, testing operators check the validity of the fracture surface to determine K1ssc in accordance with NACE TM0177 Method D 11.6. Edge cracking has been a big issue for industries.
