API Cast Steel Flanged Y Strainer


API cast steel flanged Y strainer is an essential device for medium transmission pipeline system. It is installed on pipeline and helps to remove bigger solid particles in fluid, such as iron rust and sand grain in the sewage. This cast steel Y strainer can protect pipeline accessories (compressor, pump, display instrument and other devices) from wearing and blocking in order to keep the medium transmission pipeline system work smoothly.


This flanged end Y strainer is widely applied in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, and energy pipeline systems.

Classification of Sealing Face

(Sealing surface is the most important part of API cast steel flanged Y strainer.)
1. Soft Sealing Material
(1)Rubber (like Nitrile rubber, fluoro rubber, etc.)
(2)Plastic (Teflon, nylon, etc.)
2. Hard Sealing Material
(1)Copper Alloy (for low pressure resistant strainer)
(2)Chromium Cast Steel (for common middle or high pressure resistant strainer)
(3)Stellite Alloy (for high temperature and pressure resistant and highly anti-corrosive strainer)
(4)Nickel Based Alloy (for anti-corrosive strainer)
