Y-Strainers are threaded or socket welded or flanged. They have a strainer basket as shown below.
Materials of Construction
Y typestrainers are normally made with forging process. So they are made with piping materials for forging such as :
- ASTM A105 for carbon steel.
- ASTM A182 Gr. F304L for stainless steel.
- Bronze Y-Strainers are as per ASTM B62.
Installation in Piping
Y strainers are normally required at the suction of pumps if permanent installation of a strainer is necessary. They can be installed horizontal with strainer side down for easy draining. They can also be installed in vertical piping with flow going downward.
Dimensional Standards for Strainers
Dimensional of these fittings are manufacturer specific. They depends on end conditions, rating, drain type, screen size etc. Typically dimensions are provided as shown below. Where :
- A : Inline length of fitting.
- B : Height of fitting
- E : Drain hole dia.
