SVI BREMCO designs, fabricates, and installs large-scale, process-critical industrial ductwork for facilities where reliability, thermal performance, and structural integrity matter.

We build and service engineered duct systems for power plants (simple cycle and HRSG), petrochemical facilities, chemical plants, and other heavy industrial sites with demanding thermal and structural requirements.

From field inspections to repairs and full replacement, SVI BREMCO provides turnkey ductwork support, including engineering, manufacturing, and installation.

SVI BREMCO is an industrial equipment supplier that provides industrial ductwork

Industries and Applications We Serve

Industrial ductwork varies dramatically across heavy industrial applications, but every plant has one thing in common: the ducting is part of the process, not an accessory. We support facilities that require ductwork to withstand high temperatures, corrosive environments, and dynamic operating conditions.

Power Generation

  • Gas turbine exhaust ductwork (CT exhaust plenums, diffusers and stacks)
  • Internally lined HRSG ductwork (HRSG inlet ducts)
  • Turbine air Inlet ducting and structural components
  • Stacks, silencer casings and gas path transition ducts
  • Coal plant ID and FD fan inlet and exhaust ductwork

Petrochemical and Chemical Plants

  • Large process fans and their associated ductwork
  • Single-wall or externally lagged systems for high-temperature processes
  • Corrosion-resistant materials for chemical environments

General Industrial

  • High-volume fans and blowers
  • Process air systems
  • Transition ducts and expansion joints
  • Stack repairs and replacements

Whether the application involves 1200°F+ turbine exhaust or moderately elevated fan discharge temperatures, SVI BREMCO engineers every duct section to handle the loads, support requirements, and environmental conditions of the site.

Types of Industrial Ductwork We Design and Support

Internally Lined Gas Turbine Exhaust Ductwork

Used for both Simple Cycle exhaust systems and HRSG inlet ducts. These systems require:

  • Stainless steel floating liners
  • Insulation systems engineered to meet casing temperature requirements
  • Penetrations for tubing, piping, and boiler components
  • Designs that allow for controlled thermal expansion and contraction

Common failures include:

  • Liner cracking or detachment
  • Casing hot spots
  • Weld failures caused by improper repair methods

SVI BREMCO understands floating-liner behavior and repairs or replaces systems without compromising thermal movement.

Single-Wall Ductwork

Typical in fan-driven industrial applications where internal temperatures are lower. Features include:

  • Carbon steel or stainless steel
  • Corrosion-resistant materials where needed
  • Exterior lagging (if thermal control is required)

Externally Lagged Ductwork

Designed for moderate-temperature applications where external lagging provides insulation and weather protection. We repair or replace:

  • Lagging systems
  • Weather barriers
  • Damaged or corroded casing
  • Support steel or structural components

Stacks and Silencers

We provide:

  • Full stack replacements
  • Stack repairs, thickness assessments, and corrosion evaluations
  • Silencer inspections and replacements when ejection or internal failure has occurred

Common Problems That Signal Ductwork Failure

Plant managers typically call us when they see one or more of the following:

Gas Turbine and HRSG Ductwork

  • Hot spots on duct casings
  • Cracked or failed floating liners
  • Weld failures caused by improper repair methods
  • Thermal performance degradation
  • Insulation breakdown
  • Breakout noise issues

Industrial Fan Ductwork

  • Corrosion from degraded coatings
  • Structural thinning or wall loss
  • Holes in duct walls
  • Cracking from excessive vibration
  • Degraded external lagging

Stacks

  • Visible cracking or deformation
  • Corrosion and wall-thickness loss
  • Internal component failure resulting in expelled material
  • Insurance-required inspections and analysis

If ignored, these problems lead to forced outages, equipment damage, reduced thermal efficiency, and safety hazards to plant personnel.

Inspection Services

SVI BREMCO offers multiple inspection methods to help facilities assess the condition of their ductwork well before a failure forces an outage.

Visual Ductwork Inspections

Performed internally and externally to identify:

  • Corrosion
  • Liner failures
  • Hot-spot indicators
  • Structural deformation
  • Lagging degradation

Thermography 

Thermal scanning is a critical tool for gas-turbine exhaust systems. It exposes:

  • Hot spots
  • Liner failure areas
  • Insulation breakdown
  • Gas leaks or bypass areas

Thermography is effective during operation, allowing teams to detect failure risks without opening the duct.

Stack Inspections

Performed for compliance, insurance requirements, and preventive maintenance. Includes:

  • Visual inspections
  • Ultrasonic thickness readings
  • Structural and corrosion assessments

Download our Stack Inspection Checklist from SVI BREMCO'S Experts

We’ve developed a stack inspection checklist to help you identify problems before they lead to plant downtime. There are several good reasons to inspect your stack:

  • Do you want to prevent downtime?
  • Have you noticed significant degradation of any structural component?
  • Has your stack experienced an unusual event such as an explosion, earthquake, fire or overheating?

Knowing what you should inspect annually and every three years saves you time, money, and stress.

Repair, Replacement, and Upgrade Options

SVI BREMCO provides both repair and full replacement services, depending on the condition and lifecycle goals.

Repair Capabilities

  • Sectional liner repairs
  • Casing repairs and reinforcement
  • Corrosion remediation
  • Lagging system replacement
  • Penetration seal replacements

Full Replacement

Replacement is the most reliable and cost-effective solution when:

  • Liner systems have widespread failure
  • Casing thickness is no longer adequate
  • Corrosion is extensive
  • The existing design did not meet lifecycle expectations

Upgrades and Engineering Improvements

We frequently provide upgraded solutions such as:

  • More corrosion-resistant materials
  • Upgraded severe liner systems
  • Improved thermal performance
  • Structural redesigns for better load handling
  • Acoustic solutions to reduce breakout noise

Every project begins with root-cause analysis to ensure the replacement design addresses not only the failure point but also any connected systemic issues.

Safety and Compliance on Every Project

Ductwork (especially turbine exhaust and stacks) is often a confined space requiring strict OSHA compliance. SVI BREMCO adheres to:

Safety Protocols

  • Air monitoring
  • Structural access evaluations
  • Elevated-work fall protection
  • OSHA-aligned access procedures

Engineering Design Codes

Our in-house structural engineers use industry-accepted structural and pressure-related design codes to ensure:

  • Thermal performance
