Spence Strainers International announces a line of cast iron, bronze, carbon steel, chrome molly and stainless steel Y strainers available with threaded (NPT), flanged (flat faced, raised faced and RTJ), socket weld, butt-weld and sweat end connections. The strainers are available in sizes 1/4-inch (8mm) to 16- inch (400 mm) and feature a one-piece cast body, upper and lower machined seats, drain/blow-off connections furnished with plug and stainless steel (CF8M) screens as standards.
Spence strainers are equipped with screens which have open flow areas greater than the pipe nominal cross-sectional area. This feature minimizes initial pressure drop while maximizing time between cleanings. The Y strainers are manufactured with both upper and lower machined seats, which acts to securely hold the screen in position when in service, thus eliminating debris by-pass.
