The Model YST1 and YSS1 are 316 stainless steel Y strainers (wye strainers) that can be used in applications for steam, chemicals, oil, or gas where protection from foreign matter in a pipeline is required. The YST1 has female NPT thread ends, and the YSS1 has socket weld ends. They are 600# class.
Perforated 304 stainless steel screens are welded along the seam for maximum strength. If the media is not specified, screens for steam will be supplied. Options include epoxy coating and galvanizing, and the addition of magnets.
Non-Shock Working Pressure for the YST1 and YSS1 is 600psi at 1125F for steam, 1440psi at 100F for water, oil, and gas (WOG).
These strainers self-clean by opening the drain plug connected to the blow-off port. See the maintenance instructions for more detailed information on servicing the strainer, and the submittal sheets for additional technical data.
