For plant engineers and procurement managers in the US water, oil & gas, and chemical sectors — stop guessing about flange-to-flange lengths, mesh sizes, and pressure ratings. Get the exact dimensional data you need to spec the right strainer the first time.
✅ ASME B16.5 Class 125/150/300 | ✅ Sizes 2″ – 24″ | ✅ Cast Carbon Steel / Stainless Steel
A 6″ Class 150 Y strainer from one brand might measure 12″ while another needs 14″. Result: pipe spool rework costing $1,200+ per incident.
Using a 1/16″ perforated screen when you need 40-mesh can cause pump cavitation. Downtime: average 4.7 hrs per event in chemical plants.
A flanged Y strainer labeled “Class 150” might only be shell-tested at 150 psi, not 285 psi. Risk: catastrophic flange leakage in hot oil service.
You need a supplier who publishes every dimension — not just a generic drawing.
Every unit is cast, machined, and hydro-tested in our Hebei factory. We publish true flanged y type strainer dimensions so you can retrofit without surprises.
Full dimensional data for 125/150/300# flanges.
Perforated plate (1/32″ – 1/4″) or woven mesh (20 – 200 mesh).
Material certs, PMI reports, hydro test records included.
Stock sizes ship in 7–10 days to US ports. No hidden shipping costs.
