Primary containment refers to tank units with corrosion, leaks, chemical spills, or are in need of a face lift. Tank linings must be used to protect the interior tank surfaces from further damage. R.J. Forbes uses its expertise in a wide variety of abrasive prep procedures and material application processes based on client needs and the best coating system recommended for every job.
Understanding the difference between a lining and traditional paint is very important. A lining is a fluid-applied coating system designed to be a continuous monolithic membrane that protects both the surface of a holding vessel and/or splash zone. A lining protects the material within a vessel from absorbing foreign contaminants. A traditional paint is used to provide an aesthetic appearance and to protect a substrate from normal exposure to environmental conditions such as sunlight, rain/wet conditions, and light abrasion.
Examples of places where linings are used:
Chemical Plants - holding vessels for all types of chemical materials, liquid, granular, powdered and vapor
Water Treatment Plants - drinking water tanks, pipe lines, and storage reservoirs
Waste Water Plants - waste water clarifiers, aeration basins, manholes, wet wells, influent troughs, spillways
Power Plants - fuel oil tanks
Secondary containment refers to the immediate areas/zones around a holding vessel that contain materials which are hazardous to the environment and/or people close to that vessel and must be safely protected and contained. Once material leaks from the primary holding vessel, the substrate of the holding area (secondary containment), must be prepared/coated to maintain its integrity. This coating and/or lining of the surface provides the safety and insures that the potential hazardous material is contained.
Examples of a secondary containment:
Basin, pit, trough, trench, spillway, and/or any other combination of safety holding areas for such material.
The power generation infrastructure requires continuous maintenance to insure safe operations and optimal performance. Power plants can be harsh environments with firm safety protocol. At R.J. Forbes, we are well experienced with the standard operating procedures of such plants, switch yards, transmission lines, and sub stations. The goal of all work performed in such areas is safety first with quality and everything else to follow. We focus on extensive training for all job tasks, understanding the layout of the facility in question, training/participating in lockout tag out processes and following all safety protocols entailed.
Examples of services R.J. Forbes provides for the power generation infrastructure:
Power generation stations that use turbine generators require maintenance coatings on their intake system (filter house, ducting, and inlet scroll). The extreme temperatures and rapidly moving air can create the metal structures to corrode which can cause rust scale and coating failures within these areas, sending unwanted debris into the turbine. Maintaining the coatings on these surfaces prolongs the life of the turbine itself. The cleaner the air that is drawn into the turbine equals less wear and tear and more efficient production of energy.
R.J. Forbes has performed the re-coating process on the interior of several Siemens Westinghouse turbine inlet scrolls and several GE turbines. We have developed a trusted system to protect the sensitive turbine components during the abrasive blasting and epoxy coating process of the filter house interior, ducting, and inlet scroll areas.
R.J. Forbes provides a full spectrum of tank coating and painting services for all types of storage tanks, vessels, hoppers, bins and silos. Whether storage structures hold liquids, solids, granular, or other materials, R.J. Forbes provides services to maintain, repair, and restore tanks.
The unforgiving and unavoidable environmental conditions of the waste water collection and treatment processes will cause corrosion to its infrastructure if the proper protection of its components and structures is not implemented. These surfaces demand the very best workmanship when it comes to installing protective coatings. The presence of H2S gases can crumble concrete rapidly. Installing a 100% solid epoxy coating system in vapor or splash zones can keep the concrete intact and avoid costly reconstruction of tank covers, man holes, and holding tanks.
The constant presence of moisture rich air conditions inside waste water plants and pump stations cause steel pipes, pipe supports, roof decks, and other steel structures to deteriorate. Coating and/or maintaining these structures prevents future deterioration and replacements. R.J. Forbes is extremely experienced in understanding the methods of cleaning and preparing the waste water infrastructure for recoating to achieve long-term protection of its components and buildings.
