Advantages of Tube Erosion Shields

Tube erosion shields are precision-engineered to fit straight sections, tube bends, finned pipes, and other complex geometries, providing long-term protection in high-wear boiler zones.

Also known as anti-wear plates, anti-corrosion shields, boiler tube protection covers, or snap-on climbing plates, these components are typically paired with snap rings to ensure firm and efficient installation on boiler surfaces.

Each erosion shield is manufactured using a high-pressure pressing process with precision moulds. The result is a smooth surface finish, excellent weldability, and strong attachment performance without risk of separation under thermal stress.

Curved tube shields are shaped using custom tube benders or formed under pressure, making them ideal for use in elbows, U-bends, and complex heat exchanger tube paths. The shields effectively absorb erosive wear from sootblowers, high-speed flue gas, and abrasive particles.

By preventing localized thinning and cracking, these shields significantly reduce boiler downtime, extend tube life, and lower maintenance costs, especially in CFB boilers, waste heat recovery systems, and coal-fired power plants.

Boiler Tube Erosion Shield

Installation Guide

Proper installation of boiler tube erosion shields is essential for preventing wear, prolonging service life, and avoiding critical failures like boiler explosions.

Purpose of Installation

Erosion shields are installed primarily to protect the heating surfaces of boiler tubes from high-velocity flue gases and abrasive particles. They reduce wear and enhance heat transfer efficiency in high-stress environments such as CFB boilers and waste heat recovery units.

Snap Ring Attachment Method

A snap ring is used to affix the erosion shield securely to the tube surface. It typically overlaps the shield slightly—usually with a 190°–200° arc—allowing it to clamp firmly while leaving space for welding. The ring width must be no less than 20mm for adequate support.

Installation Best Practices

Each erosion shield requires 2–4 snap rings spaced at 200–500mm intervals. The rings and shield must be fully spot welded to prevent displacement from thermal expansion and vibrations during operation.

The installation procedure varies slightly for different shapes—straight, curved, or S-type. All joints must be secure, sealed, and aligned to ensure continuous protection without gaps.

FAQ

A boiler tube shield is a protective component installed on boiler tubes to reduce erosion and corrosion caused by flue gas, ash, or particle impact in high-temperature environments.

They extend the service life of boiler tubes by protecting them from:
  • High-velocity flue gases
  • Solid particle erosion
  • Corrosive atmospheres in waste-to-energy or coal-fired plants

Common materials include:
  • Stainless steel (e.g., SS304, SS321, SS347)
  • Alloy steels (e.g., TP304H, TP347H, T91)
  • Nickel-based alloys (e.g., Inconel 625, 825) for extreme environments

  • Half-round (semi-circular) shields
  • Bent or segment shields for elbows and tube bends
  • Flat or custom-profile shields depending on installation

Custom Straight Boiler Tube Erosion Shields Installation

Boiler tube erosion shields are typically attached using the following methods:

  • Welding (tack welds or full-length)
  • Clamps or straps for removable designs
  • Snap-on/clip-on systems for fast maintenance access

Yes, slightly. Since shields add an extra metal layer, they can reduce local heat transfer. However, the trade-off is favorable because they prevent costly tube failures and unplanned shutdowns.

In some cases, yes — especially when using clamp-on types. However, shields subjected to heavy erosion or deformation should be replaced.

Yes, we accept special orders. We can manufacture custom boiler tube shields according to your technical drawings. We also ensure confidentiality through signed agreements before design submission.

Tube Erosion Shield

Service Life

The service life of boiler tube erosion shields varies depending on boiler type and installation location.

Normally, shields last throughout one overhaul cycle (3–5 years). During major maintenance, shields are inspected and replaced if:

  • They are excessively thinned or deformed
  • They detached during operation due to poor welding
  • New areas show wear and require added protection

In sections such as superheaters and economizers, erosion shields are placed on the flue gas flow-facing side of the tubes to protect against high-temperature abrasion. Curved shields are essential for elbows and U-bends to prevent wear in circulating fluidized bed (CFB) boilers, where demand is increasing.
