Spirax Sarco SMC32 & SMC32Y Carbon Steel Bimetallic Steam Traps
Spirax Sarco SMC32/SMC32Y bimetallic steam traps in carbon steel. Rated to 32 bar g, ideal for process steam lines. Available at PC Engineering India.
Overview
The Spirax Sarco SMC32 and SMC32Y are maintainable bimetallic steam traps constructed from carbon steel, designed for reliable condensate removal in industrial steam systems. These traps feature straight-through connections and are suitable for applications requiring robust performance under high-pressure and high-temperature conditions.
The SMC32 variant includes an integral flat strainer screen, while the SMC32Y incorporates a cylindrical Y-type strainer for enhanced debris filtration. Both models utilise a corrosion-resistant bimetallic element that responds to temperature variations, ensuring efficient discharge of condensate while minimising live steam loss.
All pressure-bearing components are manufactured by TÜV-approved suppliers in accordance with AD-Merkblatt WO / TRD 100. The SMC32 and SMC32Y fully comply with the European Pressure Equipment Directive 97/23/EC and are available with EN 10204 3.1 certification on request.
