Outer Half Round 90 Degree Bend Tube Shield
Ladhani Metal Corporation delivers high-performance SS 316L Outer Half Round 90 Degree Bend Tube Shields designed to protect the outer curvature of 90-degree bends and U-bend tubes in boilers, heat exchangers, HRSGs, and steam systems. Fabricated from low-carbon austenitic stainless steel grade SS 316L, these shields provide superior resistance to corrosion, particularly in chloride-rich and acidic environments, while minimizing the risk of sensitization during welding or high-temperature service.
The semi-cylindrical geometry ensures a precise fit over the outer arc of curved tubes, creating a durable shield against erosion, thermal shock, and corrosive flue gases. SS 316L shields are particularly effective in coastal, marine, and chemical plant applications where high corrosion resistance and mechanical integrity are essential.
Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of SS 316L Outer Half Round 90 Degree Bend Tube Shields, offering tailored shielding solutions to match your plant's design and performance specifications.
