Durable Boiler Tube Protection
Premium 316l stainless steel tube shields provide exceptional erosion and corrosion resistance for boiler tubes, extending service life and reducing maintenance costs in harsh industrial environments.
High-quality protective sleeves engineered from low-carbon 316L stainless steel for superior erosion, corrosion, and wear resistance in harsh industrial environments.
The 316L Tube Shield ET Wear Shield is a high-quality protective sleeve made from low-carbon 316L stainless steel, engineered specifically for the protection of boiler tubes and industrial piping against severe erosion, corrosion, and mechanical wear. This wear shield is designed to withstand harsh operating conditions in power generation, chemical processing, and marine industries where tubes face constant exposure to acidic flue gases, moisture, and abrasive particles.
Featuring superior resistance to chloride-induced pitting and crevice corrosion due to its molybdenum-enriched composition, the 316L stainless steel shield ensures reliable protection under continuous high-temperature service, typically up to 870°C (1600°F). Its robust design is available in multiple forms such as U-shaped half sleeves and fully enclosed tube shields, facilitating easy installation by welding or clamp methods.
By deploying these wear shields, industries can significantly extend the operational lifespan of boiler tubes and process pipes, minimizing downtime and maintenance costs. This solution addresses the critical need for corrosion-resistant tube protection in environments prone to acid attack and erosive wear.
316/316L stainless steel is widely used in chloride and chemical process environments due to its enhanced resistance to corrosion and pitting, attributed to its molybdenum content. These alloys offer excellent mechanical and corrosion-resistant properties across a range of temperatures and environments, making them essential in chemical processing, marine, and high-temperature industrial applications.
Low carbon version of 316, offering superior resistance to intergranular corrosion after welding. Commonly used in marine and chloride-rich environments. Excellent weldability without post-weld annealing.
High carbon content variant suitable for elevated temperature service. Offers greater short and long-term creep strength. Commonly used in high-stress boiler or furnace applications.
Standard molybdenum-bearing austenitic stainless steel. Excellent resistance to chlorides and moderate acids. Widely used across various chemical and process industries.
