Use of Atlas Test Cells to Assess the Performance of Coatings with Varied Permeance over Concrete Masonry Units (CMU)

Product Number: 41212-695-SG

Author: Cindy O’Malley, Chuck Duffin, Steve Revnew

Publication Date: 2012

The permeance of coatings applied to the walls of Single Wythe concrete masonry units (CMU) can affect the long-term performance of the coating system, especially after multiple repaints. This paper describes the results of a study to determine if the Atlas Cell Test (NACE TM0174/ASTM C868) can be modified to evaluate the performance of individual coating systems based upon permeance.

Use of Glass Reinforced Epoxy (GRE) Piping for Fire Water Applications – Offshore

Product Number: MPWT19-15300

Author: Stephen Ching

Publication Date: 2019

$0.00

The fire water system on an offshore facility is a critical system. In the event of a fire, this system must not only deliver water for active fire management, but the system must also survive the worst-case scenarios of blast, jet fire and or hydrocarbon fire and for a duration anticipated in that scenario. The fire water system must also survive the duration of time needed for the safe evacuation of personnel from the facility.
This paper addresses the complexities involved in the use of composite pipes for fire water applications. It focuses on how blast effects are managed and the survivability of GRE piping in highly intense and high heat flux fire cases. Results from tests simulations will be shared which were carried out to assure certifying body, operator and engineer that GRE piping is the right material of choice for this application under such circumstances.
The paper concludes with examples of several floating production and storage offloading facilities installed with GRE piping for the fire water application.

Use of Hygrothermal Models for Understanding Water Transport in Corrosion Under Insulation Application

Product Number: 51319-13484-SG

Author: Sai Prasanth Venkateswaran

Publication Date: 2019

$20.00

Thermal insulation is used in operating facilities to conserve heat and protect against freezing amongst others. A consequence of insulating the pipe is the necessity to manage the introduced threat of corrosion under insulation (CUI). For CUI to occur water and oxygen must enter and migrate through the insulation to reach the external surface of the pipe. The water transport characteristics are dependent on several factors such as type of insulation type of jacketing pipe operating temperature external weather water entry/leakage rate and cyclic service. In hot piping there are competing water transport characteristics as in water vapor moves outwards away from the pipe as water enters into insulation. Knowing the water transport and the parameters that influence the time of wetness at the metal surface helps in understanding conditions favoring CUI.The use of transient hygrothermal models for moisture control is well established in the building insulation design codes and standards. The building designs naturally shed the liquid water to minimize entry and facilitate breathing of vapor so that moisture doesn’t accumulate within building. Several building industry hygrothermal models have been developed and are available for commercial use. One such commercial model has been used to understand water transport in a CUI application. The case study involves evaluation of piping and pipeline installed with a closed cell polyurethane insulation. The hygrothermal model provided insights on the parameters influencing the time of wetness and the ease of water escaping the pipe-insulation-jacketing system. Additional results comparing different insulations are also presented.Key words: Corrosion under insulation water transport hygrothermal models building industry polyurethane insulation

Use of Large Standoff Magnetometry in Pipeline Integrity Investigations

Product Number: 51320-14475-SG

Large standoff magnetometry (LSM), a novel screening technology, has shown strong industry relevance in several pipeline integrity investigations. LSM is used to detect changes in the magnetic field of a pipeline due to changes in the magnetic susceptibility of steel. These changes are known as inverse magnetostriction (a.k.a. the Villari effect) and occur when a ferromagnetic material (steel) is subjected to mechanical stress, such as the presence of stress on the wall of a pipeline. Geometric anomalies (ovalities, dents, wrinkles), hoop stress, ground and slope movement, bend strain, thermal expansion, cracks, and material defects are examples of potential sources of stress that LSM can detect from aboveground.

This paper summarizes the use of LSM as a complimentary tool in several pipeline integrity assessments conducted on oil and gas pipelines, in this case, to pinpoint a lost inline inspection pig and to identify dents, cracks, buckles, slope movement, casing ends, unknown valve locations and other pipeline integrity and direct assessment applications. Ongoing development programs and lessons learnt from practical, real-life projects and validations of the technology are presented to demonstrate the effectiveness of LSM for pipeline integrity investigations.

Use Of Potential Probes To Monitor Cathodic Protection: Accuracy Of The IR-Free Potential Measurement

Publication Date: 2021

$20.00

Cathodic protection (CP) is an electrochemical corrosion prevention technique, which is implemented by circulating a direct current between an electrode (anode) placed in the environment and the structure to be protected (the cathode): this current causes a lowering of the potential of the metal and reduces its corrosion rate, until it stops.

Water, steam, and waterjetting have long been used in the conservation of historic artifacts and structures such as the R.M.S. Titanic and the Saturn V Rocket at Johnson Space Center. Integral to the conservation is the removal of loose material, reduction in salts and corrosion, retention of coatings and desirable patina, and repair of damaged areas.

Use of Zinc Thermically Sprayed As Sacrificial Anode for Protecting the Inner Surface of Pipeline Welded Joints

Product Number: 51319-12996-SG

Author: Joao Paulo Gervasio

Publication Date: 2019

$20.00

The corrosive fluids transportation inside carbon steel pipelines is critical due to internal corrosion. To avoid failures barrier corrosion protection techniques are applied by insulating the inner metal wall of the pipe. However when the tubes are welded together the inner coating is damaged by the heat generated during the welding process. As a result the ends of the tubes are uncoated and consequently subjected to corrosion. There are solutions to this problem but all have some kind of inconvenience either by the cost of implementation or the difficulty of application. This work aims to present the results of the tests of the application of an alternative technique: zinc thermally sprayed as sacrificial anode for internal protection of welded joints.
