Sour Weld Corrosion Mitigation with a Low Dose Inhibitor

Product Number: 51319-13324-SG

Preferential weld corrosion offers a uniquely different mitigation challenge to operators of high throughput oilfield production in carbon steel pipelines. This has a significant impact on the expected lifetime of the pipeline and thus will require chemical inhibition programs to control such localized corrosion effects. As a part of OPEX these programs require field optimization whilst providing the desired level of corrosion protection at minimum inhibitor dose rate.A low dose corrosion inhibitor has been developed that inhibits sour corrosion of individual weld components of pre-corroded steel coupons prepared from pipeline material. Metallurgical analysis of the weld section extracted from the pipeline was performed which illustrated unusual composition of the material.The lower corrosion inhibitor dose also reduces the influence of secondary effects (including emulsion and foaming) eliminating the need for specialized formulation additives and the injection of additional chemistries. Due to the low water cut and the stratified flow regime of a subsea pipeline the partitioning behavior of the product was an important consideration during product development. Since the treatment of bacteria in the pipeline was necessary the compatibility of the inhibitor with the incumbent biocide was critical.This paper details the test work performed to develop a new inhibitor to prevent weld corrosion under sour conditions. The inhibitor was evaluated in numerous performance under including kettle tests high pressure autoclaves partitioning and autoclave weldment corrosion tests.

Southern Nevada Water Authority-Polyurethane Lining Evaluation and Testing

Product Number: 41211-637-SG

Author: Cynthia L. O’Malley, Gina Neilson

Publication Date: 2011

$20.00

The Southern Nevada Water Authority (SNWA) is a regional agency whose mission is to manage water resources and develop solutions that will ensure adequate future water supplies for the Las Vegas Valley. Its primary water resource is the Colorado River via Lake Mead. Since 2000, persistent droughts have resulted in decreasing Lake Mead water levels. To reduce Southern Nevada’s reliance on the Colorado River, SNWA has begun planning for the development of in-state groundwater resources north of Las Vegas. Initial planning efforts identified project specific requirements that could potentially justify the use of polyurethane lining systems in lieu of traditional cement mortar lining for over 200 miles of large diameter water transmission pipeline.

Chloride-induced corrosion of steel reinforcement in concrete structures usually experiences two stages: pitting corrosion initiation and propagation.1-2 Initiation of pitting corrosion occurs as the chloride content on the surface of a steel bar exceeds a critical value (or chloride threshold) and breaks down the passive film locally.^3-4 Depending on environmental factors at the steel-concrete interface, such as temperature, moisture, and availability of oxygen, pitting corrosion initiation is not stable in the very beginning and some corrosion pits may continue to develop and become stable, while others cease.

Special Forgings. Technical and Quality Requirements Supplementary to Standard

Product Number: MPWT19-15297

Author: Ricardo Hernández Soto, Abdullah M. Al-Rumaih

Publication Date: 2019

$0.00

Long weld neck flanges, self-reinforced forged connections (SRCs), forged Y-rings and other special
forgings are widely used in pressure-vessel fabrications for Oil and Gas industry. ASTM(1) A-350 LF2
Class 1 is one of the most common materials specified for these tailor-made components, especially for
SRCs on pressure vessels with toughness requirements, as this material warranties 20 Joules (average
of three specimens) at -46 ºC. However, in recent years there has been growing concern in the industry
as a result of the increasing number of cases of low toughness and low tensile strength issues with
materials certified as ASTM A-350 LF2. This is fostering the definition of additional requirements to the
ASTM to minimize the risk.
The complexity of the metallurgical processes involved in mechanical properties deterioration, where
multiple variables interact, mandates to implement control majors during the fabrication of ASTM A-350
forging materials. This paper introduces some guidelines to enhance the quality control and mechanical
testing reliability in the certification process of special forgings carried out by manufacturers. These
guidelines can be applied to not only to those made of ASTM A-350, but also to ASTM A-266 and ASTM
A-765

Specially Developed Welding Consumables for Pipeline Welding Applications

Product Number: MPWT19-14364

Author: MPWT19-14364

Publication Date: 2019

Apart from the well-tried cellulosic electrodes, in the range from E6010-E9010, there are
also low hydrogen grades of weld consumables, which are used in vertical downhill
position - commonly called as BVD (Basic Vertical Down) electrodes. In addition, the
seamless flux cored wires, are gaining prominence in the welding industry as a better
solution compared to the conventional cellulosic electrodes.
The development of BVD electrodes started because of the desire to use high-strength
TM pipe steels with relatively high toughness (e.g. X80). Cellulosic electrodes could not
meet the requirements for cold crack resistance and high toughness properties of the
weld metal. To a high degree, economical efficiency is determined by the achievable
deposition rate and the possible welding speeds. In comparison to basic vertical-up
electrodes, significant time advantage of 40-50% can be achieved with the use of BVD
electrodes for the fill and cap layers.
Seamless Flux Cored wires for pipeline applications follow a different manufacturing
approach compared to the conventional folded techniques and are much reliable with
consistent performance in terms of weldability and quality. The seamless FCAW wires,
offers a unique and trustworthy solution in terms of arc stability and low defect rates.
These wires are also suitable to be used under sour service applications having been
tested for Hydrogen Induced Cracking (HIC) and Sulfide Stress Cracking applications.

In oil and gas production, corrosion is a major cause of failures. These failures result in significant environmental contaminants, safety problems, increase in the high operating costs and decrease in the production rates. Extensive literature is available about various corrosion drivers and their mechanisms, helping operators to avoid or mitigate these catastrophic failures.
