Y Strainers

Structure

Y-Strainers are threaded or socket welded or flanged. They accept a strainer basket equally shown beneath.

Materials of Construction

Y typestrainers are commonly made with forging procedure. So they are made with pipage materials for forging such every bit :

ASTM A105 for carbon steel.
ASTM A182 Gr. F304L for stainless steel.
Bronze Y-Strainers are as per ASTM B62.

Threaded Y Strainer

This is used in small bore threaded pipe upto 3" size. it has threaded bushing at bottom finish with a screw to remove dirt. Screen tin exist removed by unscrewing the bushing. These fittings are forged fittings and fabric of construction is forged steel like ASTM A105. Screen is made of stainless steel.

Socket Weld Y Strainer

Socket Weld Y Strainer is used in pocket-sized diameter socket weld pipe where threaded fittings can't be used. They are normally available upto 3" size. These are forged fittings. Bottom flange has a drain spiral for quick removal of clay.

Bronze Y Strainers

They are used for water services and are made with bronze metal as per ASTM B62 and B584. They are threaded upto 3". For larger size, they are flanged with flat face up. (Flat face with full face gasket required to avoid neat of flange articulation during commodities tightening)

PVC Y Strainer

Used in water services, they are made with thermoplastic Poly Vinyl Chloride (PVC). They are made in 85psi and 150psi ratings. Stop connections available are socket, threaded and flanged. Screen is made of stainless steel.

Installation in Pipage

Y strainers are normally required at the suction of pumps if permanent installation of a strainer is necessary. They can exist installed horizontal with strainer side down for easy draining. They can as well be installed in vertical pipage with menstruum going downwardly.

Dimensional Standards for Strainers

Dimensional of these fittings are manufacturer specific. They depends on stop weather, rating, drain type, screen size etc. Typically dimensions are provided as shown below. Where :

A : Inline length of plumbing equipment.
B : Tiptop of fitting
E : Bleed hole dia.
