Spirax Sarco Fig 12 SG Iron Y-Type Strainer, IBR certified, for steam & liquid filtration. Sizes ½" to 3", 17 bar g. Buy from PC Engineering India.
Overview
The Spirax Sarco Fig 12 is a robust SG iron Y-type strainer designed for pipeline protection in steam, condensate, and liquid applications. It removes particulate matter and debris from process lines, safeguarding downstream equipment such as steam traps, control valves, and pumps from damage and blockage.
Constructed with an SG iron body and featuring a standard 316L stainless steel screen with 0.8 mm perforations, the Fig 12 strainer offers reliable filtration performance. The Y-type configuration allows for inline installation and easy maintenance without removing the strainer from the pipeline. Optional screen materials and mesh sizes are available for application-specific filtration requirements.
This strainer fully complies with Indian Boiler Regulations, 1950 (IBR) and is available with IBR certification and manufacturer's Typical Test Report—essential documentation for boiler house and regulated steam system installations across Indian manufacturing facilities.
