Surface Preparation: Key to Protective Coating Excellence

Surface Preparation: Key to Protective Coating Excellence

The old adage “preparation is key” couldn’t ring truer when applied to protective coatings in the corrosion prevention, water, and wastewater industries. Whether safeguarding a water storage tank against the elements or enhancing the lifespan of wastewater treatment process equipment, applying protective coatings is only as effective as the surface preparation performed before it is applied.  V&A’s new blog post discusses the significance of surface preparation and provides an overview of industry standards. Protective coatings offer the first line of defense against the harmful effects of a corrosive environment on infrastructure.

The Significance of Study Duration in Sewer Flow Monitoring Programs

The Significance of Study Duration in Sewer Flow Monitoring Programs

V&A’s latest blog article unravels the critical role of study duration in sewer flow monitoring programs. From hydraulic modeling and RDII analysis to compliance monitoring, we explore why the clock matters in understanding the operation of sewer systems. In wastewater infrastructure management, sewer flow monitoring programs are a critical tool for assessing the functionality and efficiency of sewer systems. A key parameter influencing the precision and reliability of these programs is the duration over which monitoring takes place.

This article explains why study duration is pivotal in extracting meaningful insights. From the nuanced calibration requirements of hydraulic models to the meticulous analysis of Rainfall-Dependent Infiltration and Inflow (RDII), the time-based scope of monitoring programs is a decisive factor in informing data-driven decision-making for sustainable sewer system operation.

Protective Coatings on Welded Steel Storage Tanks: Is It Time to Repair or Replace?

Protective Coatings on Welded Steel Storage Tanks: Is It Time to Repair or Replace?

The decision to repair or replace a protective coating on welded steel storage tanks depends on several factors, including the condition of the existing coating, the extent of damage or deterioration, the remaining service life of the storage tank, budget considerations, and environmental considerations.

Generally, a high-quality protective coating on a well-maintained welded steel storage tank can sometimes have a lifespan of 20 to 40 years or even longer. However, premature coating failure can occur due to various factors, and ongoing inspections and maintenance are crucial to ensuring the longevity of the coating.

How does an owner know when to repair or replace protective coatings?

Factors Impacting the Cost of Pipeline Condition Assessment

Factors Impacting the Cost of Pipeline Condition Assessment

Water and wastewater utilities face the challenge of maintaining infrastructure that has served for decades. Buried pipeline infrastructure poses accessibility challenges from physical limitations and operational constraints. Consequently, utilities must strategize effectively to plan for potential rehabilitation or replacement initiatives. The optimal approach involves conducting a comprehensive field-based condition assessment, ensuring the availability of up-to-date and precise data for informed decision-making. However, the logistics of gathering condition data can be challenging, impacting the pipeline condition assessment cost.

Cell-to-Cell Surveys for Identifying Active Corrosion on Mortar-Coated Steel Pipes

Cell-to-Cell Surveys for Identifying Active Corrosion on Mortar-Coated Steel Pipes

Corrosion in infrastructure systems, such as steel pipes, significantly threatens their structural integrity and longevity. Detecting and monitoring corrosion promptly is crucial to ensure the safe operation of these infrastructure assets. In the case of mortar-coated steel pipes, corrosion can occur underneath the protective mortar layer, making it challenging to identify without invasive investigative techniques. Cell-to-cell surveys assess the likelihood of active corrosion on mortar-coated pipe materials due to the loss of intimate contact between the steel cylinder and the mortar coating.

GACP vs. ICCP - Which Cathodic Protection System is Right for my Project?

GACP vs. ICCP - Which Cathodic Protection System is Right for my Project?

Corrosion is a primary concern for pipelines as it can cause significant damage to the pipeline structure and potentially lead to leaks, which can be costly to repair and environmentally harmful. Cathodic protection (CP) systems help minimize the risk of pipeline leaks and damage by providing protection from potential corrosion issues. Often, the first decision the design engineer, owner, and operator of a pipeline needs to make after determining whether the soil is corrosive is whether to use a Galvanic Anode Cathodic Protection (GACP) or an Impressed Current Cathodic Protection (ICCP) system.

How do you know which cathodic protection system is suitable for your project?
