Sure Flow Fabricated “Y” Strainers can be designed to your specific application in Carbon Steel or Stainless Steel, along with other materials such as exotic alloys. Pipe
sizes 2” to 24” in Class 150 and Class 300 ASME flanges
are standard with the capability to supply larger pipe sizes and/or
higher ASME pressure ratings. Screen sizes can be tailored to hold sufficient solids for the required time between clean-outs. Flange sizes can be chosen to fit existing piping, or to achieve the required clean pressure drop. Hinge covers are also available for quick opening. Please contact factory for details.
The Sure Flow Fabricated “FWT” Y strainer differs from the “FW” Y strainer by incorporating standard buttweld components into its construction. Fabricated in Carbon or Stainless Steel, pipe sizes 2” through 24” and in Class 150 and Class 300 ASME flanges,
the standard strainer is suited for many applications.
Sure Flow also has the capability to supply larger pipe sizes and/or higher ASME pressure ratings where needed. Screen sizes can be tailored to hold sufficient solids for the required time between clean-outs. Flange sizes can be chosen to fit existing piping, or to achieve the required clean pressure drop. Hinge covers are also available for quick opening. Alternate materials of construction are available. Please contact factory for details.
