Corrosion Under Insulation (CUI) in pipingc systems consumes a significant percent of the maintenance budget in the petrochemical industry. Prevention of CUI by the use of (1) thermal spray aluminum, (2) stainless steel pipe, (3) expanded metal cages for personnel protection instead of insulation and (4) aluminum foil wrapping are discussed in terms of long term protection, installed cost and Life cycle cost.

A High Performance Thermal Insulative Coating For Personnel Protection

Product Number: 51323-18941-SG

Author: Naoki Maruyama

Publication Date: 2023

$20.00

In industrial plants such as oil & gas and chemical plants, the plant piping is covered with insulative materials such as mineral wools and metal cladding for thermal insulation. The piping under insulation is subject to more severe corrosive environment than that exposed to the outdoor, due to rainwater entering through the cladding joints and condensation caused by temperature fluctuation. In addition, since the piping is covered with the insulation materials, it is impossible to identify the corrosion from the outside, increasing the risk of leakage accidents due to delays in corrosion mitigations.

A Novel Methodology For Addressing Corrosion Under Insulation (CUI) Utilizing Corrosion Inhibitor Impregnated Self-Amalgamating Silicone Based Tape

Product Number: 51322-17931-SG

Author: Phillip Low

Publication Date: 2022

$20.00

Integrity management of corrosion under insulation (CUI) has historically and continues to be one of the biggest corrosion related challenges within the oil & gas, maritime, chemical and petrochemical industries.² Corrosion of piping, associated flanges, pressure vessels and structural components from CUI is a commonly found phenomenon and if left undetected or not stringently managed can result in catastrophic leaks or explosions, equipment failure and periods of prolonged downtime due to repair or replacement. It is estimated around 40% to 60% of an operator’s pipeline maintenance budget is a result of CUI.³

A Prediction and Inspection Technology for Detecting the Corrosion Under Insulation

Product Number: MPWT19-15162

Publication Date: 2019

$0.00

Corrosion under insulation (CUI) is a critical challenge that affects the integrity of assets for which the oil and gas industry is not immune. Over the last few decades, both downstream and upstream industry segments have recognized the magnitude of CUI and challenges faced by the industry in its ability to handle CUI risk-based assessment, predictive detection and inspection of CUI. It is a concern that is hidden, invisible to inspectors and prompted mainly by moisture ingress between the insulation and the metallic pipe surface. The industry faces significant issues in the inspection of insulated assets, not only of pipes, but also tanks and vessels in terms of detection accuracy and precision. Currently, there is no reliable NDT detection tool that can predict the CUI spots in a safe and fast manner. In this study, a cyber physical-based approach is being presented to identify susceptible locations of CUI through a collection of infrared data overtime. The experimental results and data analysis demonstrates the feasibility of utilizing machine-learning techniques coupled with thermography to predict areas of concern. This is through a simplified clustering and classification model utilizing the Convolutional Neural Networks (CNN). This is a unique and innovative inspection technique in tackling complex challenges within the oil and gas industry, utilizing trending technologies such as big data analytics and artificial intelligence.

Publication Date: 2023

To properly protect workers from skin-contact burns in compliance with U.S. Occupational Safety and Health Administration (OSHA) guidelines, it is imperative that the coating provides the proper system barrier and prevents heat transmission that could cause irreversible tissue damage. For passive heated surfaces, ASTM C1055 (Standard Guide for Heated System Surface Conditions that Produce Contact Burn Injuries), (1) and ASTM C1057 (Standard Practice for Determination of Skin Contact Temperature from Heated Surfaces Using a Mathematical Model and Thermethesiometer) provide the standard procedure to test a coatings ability to prevent serious burn injuries and provides the skin temperature limits that human tissue endures before irreversible harm (Figure 1). There are two primary methods used to comply with these OSHA guidelines for workers who may come into contact with pipe and tank surfaces.
