Spirax Sarco Fig 37 SG Iron Y-Type Strainer - IBR Certified, DN15 to DN200

Overview

The Spirax Sarco Fig 37 is an SG iron Y-type strainer designed for pipeline protection in steam, condensate, and general industrial fluid systems. It features integrally flanged connections and a robust body construction suitable for demanding plant environments.

The strainer is equipped with a stainless steel screen as standard — 0.8 mm perforations for DN15 to DN80 sizes and 1.6 mm perforations for DN100 to DN200. Optional screen materials include monel, and alternative perforation sizes (1.6 mm, 3.0 mm) or mesh configurations (40, 100, 200 mesh) are available for specific filtration requirements.

This product fully complies with Indian Boiler Regulations (IBR), 1950, making it suitable for regulated steam applications across Indian manufacturing facilities. The strainer cap can be drilled and tapped for blowdown or drain valve connections as an optional extra.

Key Features

  • SG Iron body (GGG 40) for high strength and corrosion resistance
