310S stainless steel steam boiler tube erosion shields are premium-grade protection components designed to shield critical areas of boiler tubes from erosion, abrasion, and high-temperature oxidation. These shields are fabricated using AISI 310S, a high-performance, heat-resistant stainless steel known for its superior resistance to scaling, thermal fatigue, and aggressive gas corrosion at temperatures up to 1100°C (2012°F).

In modern steam boilers, erosion commonly occurs where flue gas velocity is highest—such as at bends, tube crossings, and slag-impact zones. Without proper shielding, boiler tubes in these locations suffer wall thinning, resulting in leaks, failures, and unplanned shutdowns.

Key Features

Excellent heat resistance: Withstands prolonged operation at elevated temperatures.
Durable mechanical strength: Offers high creep resistance under load.
Anti-erosion performance: Resists flue gas erosion, ash abrasion, and slag impact.
Easy installation: Can be installed by welding, clamping, or snap-on systems.

Specifications

Material: AISI 310S Stainless Steel
Thickness: Typically 1.5–2.0 mm
Tube OD Fit: 38 mm – 76 mm or customized

Form: U-shape, half-wrap, or full tube coverage
Fixing Method: Spot weld, clamp-on, or custom fabrication

Application Benefits

Installing 310S stainless erosion shields is a proven, economical solution to extend tube life, enhance boiler reliability, and reduce maintenance costs. These shields are especially effective in harsh environments with high temperature and particulate flow, ensuring long-term protection for superheaters, reheaters, and water-cooled wall tubes.

Stainless Steel 310/310S

310S stainless steel steam boiler tube erosion shields are precision components made from SS310S material, offering superior protection to boiler tubes from high-temperature corrosion, flue gas erosion, and mechanical wear. These shields are widely used in power generation, waste heat recovery units, and high-temperature industrial furnaces.
