flanged series Y-strainers Engineering Data Screen Openings for Y-Strainers factors to consider purpose If the basket strainer is being used for protection rather than direct filtration, Apollo’s standard screens will suffice in most applications. service With services that require extremely sturdy screens, such as high pressure/ temperature applications or services with high viscosities, Apollo® recommends that perforated screens without mesh liners be used. If mesh is required to obtain a certain level of filtration, then Apollo recommends a trapped perf./mesh/perf. combination. filtration...

flanged series Y-strainers Installation and Maintenance Instructions strainer installation instructions A. B. C. D. E. Ensure all machined surfaces are free of defects and that the inside of the strainer is free of foreign objects. For horizontal pipelines, the strainer should be installed so that the drain connection is pointed downwards. For flanged end strainers, the flange bolting should be tightened gradually in a back and forth clockwise motion. Once installed, increase line pressure gradually and check for leakage around joints. If the strainer is supplied with a start-up screen, monitor...
