2 in (50 mm) Cast Iron Y Strainer, Table E | VDIY50

This AAP cast iron flanged Y strainer has an epoxy coated cast iron body and cover, a 304 stainless steel screen, a graphite gasket and flanges to AS 2129 Table E (manufacturer-stated). It is supplied in 10 sizes from 2 in (50 mm) to 14 in (350 mm).

A Y strainer is fitted in line to protect control equipment, instruments, pumps and regulators. Fluid passes through a perforated stainless steel or wire mesh basket held in a Y shaped body. The basket traps fines and solids, which fall into the leg of the body. AAP says the leg can be flushed out while the plant is running if a ball valve is fitted to it, or the basket can be taken out for cleaning when the plant is shut down.

AAP gives a maximum working temperature of 120 degrees C and a cold working pressure of 1,600 kPa (16 bar), and lists the strainer for water, oil and air (all manufacturer-stated). The screen openings listed by AAP are 1.5 mm diameter holes at 4.5 mm spacing for 50 mm to 150 mm strainers, giving an effective open area of 33 per cent of the inlet pipe, and 3 mm diameter holes at 7.5 mm spacing for 200 mm to 300 mm strainers, giving 44 per cent. AAP does not list a screen for the 14 in (350 mm) strainer.
