9 Calculations are performed usingstandard gaskets and with the existence of aedge moment. The gasket cavity is fully enclosedensuring proper gasket alignment while preven-ting unwinding of spiral wound gaskets if 600Y2, 900Y2 and 1500Y2 strainersincorporate a body-cover joint that is in dimen-sional accordance with the flange dimensionsspecified in ASME Among the advantagesof this strong leak-proof design is the conveni-ence of using gaskets that are in accordancewith ASME and ASME Thisfeature eliminates the need for dimensionallyspecial gaskets when maintenance is STRAINER DESIGN FEATURESBODY-COVERTHREADEDJOINTSThe design of a strong threaded body-coverjoint is dependent on many factors.

10 Whendesigning these joints for strainers , calculationsare performed taking into account thread shear(ASME ), cover thickness and operating/gasket seating loads (ASME Sect.
