Product Description

Forged Steel Thread Ends  Y Type Strainer 150LB~2500LB

  1. RST Valve company is a industry valves manufacturer, including Thread & Flange Ball Valves, Gate Valves, Globe Valves, Check Valves, Y Strainers in stainless steel, carbon steel, cast steel, forged steel and alloy steel.

  2. These strainers are usually supplied in one of four materials: iron, carbon steel, bronze, or stainless steel.Iron is used most often because it costs the least, and has good corrosion resistance in many services. Carbon steel is used where higher temperatures, or concern with      thermal or mechanical shock is an issue, which makes them popular in the oil and petrochemical industries.  Bronze handles thermal and mechanical shock better than iron, and is better in some corrosive applications, but is limited in temperature range.  Stainless steel is needed where corrosion could be an issue, and is widely used in the chemical, food, and pharmaceutical industries.

  3. They are provided with a variety of end connections, including threaded, flanged, and welded.  Standard screens are provided for either steam service  or WOG (water, oil, gas) service, but other screens are available on request.

  4. Forged Steel Y-Strainer is designed and manufactures accordance to ASME Standard allows      mechanically removing solids from flowing liquids or gases by means of a perforated straining element. These strainers are vital to protect control valves, pressure reducing valves, steam traps, pumps and measuring equipments from damage by the scale or dirt in the piping system.

  5. Forged Steel Y-Strainer can be installed in any position on the pipeline, paying attention to correct flow direction of medium that should be in accordance with marking on the body. It is widely used in process industries such as Palm Oil and Refinery Plant, Petrochemical, Power Plant, Oil and Gas Industries, Pulp and Paper Mill, Heating and Cooling System.

  7. Drain/Blow-off connection furnished with plug as standard.

  8. Generous screen area and properly proportioned straining chamber to minimize initial pressure drop while maximizing time between cleanings.

Service Considerations: 

  1. For maximum protection, collected material must be discharged through the blow-off connection on a routine basis.

  2. A permanent blow-down line and ball valve with each strainer will result in simplified      cleaning.

  3. Install horizontally or vertically with dirt collecting inside the screen.

  4. Screen can also be removed and cleaned with solvent and compressed air.

  5. Inspect the gasket and replace if necessary when replacing the screen.
