It is well known in the hot rolled steel making business that nonmetallic inclusions play critical
role in defining steel performance. The objective of this paper is to study laminations that were
detected via Phased Array UT system in X60MS Class-C High Frequency Welded Pipe intended for
offshore application. The linear intermittent laminations appear along the pipe and adjacent to
the weld seam from both sides at a width of 30 to 40 mm with various depths. Technical review
was carried out on 5 available pipes, pertaining to the same heat of the original pipe identified
earlier with lamination, through model experiments; both on the laboratory and on the industrial
scale. At the beginning, depth and distribution of detected laminations were analyzed by manual
UT mapping using normal beam probe. Metallurgical analysis via Energy Dispersive X-ray (EDX)
was carried out on three samples to determine the chemical composition as well as the
morphology of the lamination. The type of inclusion which turned out to be type B (Alumina-
Al2O3) inclusion was identified by evaluating EDX results using Method A per ASTM E45. As it is
a pure material based incident, failure analysis was carried out by the steel maker to identify the
associated root causes from process control prospective and the appropriate preventive
measures to avoid reoccurrence. Eventually, the applied quality control measures during
manufacturing process of HFW pipes, represented in the deployment of UT systems, were
reviewed to identify the reason behind missing such important defect before pipes are being
shipped to the client.

Techniques for Inspecting Wall Thickness Metal Loss of Pipelines under Nonmetallic Sleeves

Composite repairs have been applied to pipelines and piping systems for structural reinforcement after external corrosion. Such repairs may consist of glass or carbon fibers embedded in a matrix of epoxy. Typically, these repairs are hand applied using either wet lay-up systems or prefabricated rolls of composite sleeve. In some applications, pipeline continued corrosion growth under composite repairs were reported using Inline Inspection (ILI) which raises a concern about the integrity of the metallic piping under composite repairs. When continued corrosion is detected by ILI, a difficulty is typically faced due to the inability to measure pipeline remaining thickness under such repairs. To resolve this challenge, this paper will discuss multiple inspection and corrosion monitoring techniques for metal loss under composite repairs. To measure the pipeline wall thickness due to internal corrosion, one or more of the three (3) Non-Destructive Testing (NDT) technologies namely; Dynamic Response Spectroscopy (DRS), Multi-skip Ultrasonic (MS-UT) and digital radiography were evaluated and found capable. To monitor for external corrosion, a scheduled visual inspection of the composite repair would be the first inspection step. If the composite repair appears to be intact then the visual inspection would suffice and the repair should be acceptable to its design life. If the original defect is external corrosion and a scheduled visual inspection of the composite repair shows damage to the composite repair then inspection to assess the integrity of the substrate must be used before permanently fixing the composite repair. For this scenario, digital radiography or MS-UT are recommended to assess the condition of the substrate

Technological Development of Anti-fouling Paints with EPS as a Natural Biocide

Product Number: 41214-836-SG

The exopolysaccharides (EPS) are a class of renewable natural polymers, which present anti-fouling property. Therefore, it may be used as an alternative to conventional additives currently used in anti-corrosive paints. The copper oxide is an additive commonly used due to its anticorrosive and anti-fouling properties.

Technology Advancements for Electrochemical Protection Systems of Reinforced Concrete Structures, Across Australia

Product Number: 51323-18881-SG

Author: Nicholas Critchley, Blane McGuiness, Oliver Gasior

Publication Date: 2023

$20.00

Electrochemical protection techniques have provided owners of reinforced concrete infrastructure a highly effective option for controlling reinforcement corrosion. This is particularly so for coastal assets, such as wharves and bridges which are exposed to seawater and in turn the corrosive effects that
follow as chlorides migrate through the concrete cover to the reinforcement. Protection technologies have evolved considerably over the past 30 years in the Australian market.

Technology from Outter Space to Earth: Silicones as Protective Coatings

Product Number: 41214-864-SG

Author: Mark Vedder, Brain Burkitt, Danielle Peak

Publication Date: 2014

Compared to other polymeric materials, silicone offers greater performance in harsh environments. Inherently silicone possesses a large coefficient of thermal expansion (CTE), low modulus, and a low glass transition temperate (Tg). These attributes allow it to maintain elastomeric properties for continuous operation when exposed to extreme heat, cold, and/or UV radiation. Durability is the reason silicone materials are frequently employed as coatings and sealants.

Temporary Coating for In Process or Storage Applications

Product Number: 51218-092-SG

Author: Markus Bieber

Publication Date: 2017

$20.00

There is a tremendous need for the protection of assets during processing, shipment and storage. Critical spares must be readily available and easy to place into service with minimal impact to the operation of equipment. The proven technology of VCIs (Vapor Corrosion Inhibitors) has long been used to preserve many of these assets using traditional mechanisms such as papers and films.
