Basket Strainer

Falcon Valves & Flanges Pvt Ltd is a prominent manufacturer specializing in industrial filtration solutions. Our Basket Strainers (also known as Pot Strainers) are engineered for high-capacity filtration and the protection of downstream equipment like pumps, valves, and meters from debris and foreign particles.

Below is a brief description of their offerings categorized by your specific requirements:

Falcon manufactures strainers that cater to both small-scale and large-scale industrial pipelines:

• Standard Sizes: From 15 NB (1/2") to 1500 NB (60").

• Filter Element: Micron meshes and screens available from 10 microns to 6000 microns.

• Configurations: Available in Simplex (single basket) and Duplex (twin basket with a changeover valve for continuous operation).

Falcon offers a diverse selection of Materials of Construction (MOC) to suit various corrosive and high-temperature environments:

• Carbon Steel (CS): ASTM A216 WCB (Cast), ASTM A105 (Forged), or fabricated carbon steel for general industrial and oil/gas services.

• Stainless Steel (SS): Grades including SS304, SS304L, SS316, and SS316L. These are ideal for food, pharmaceutical, and chemical applications where corrosion resistance is vital.

• Alloy Steel: High-temperature and high-pressure alloy grades for power generation and heavy industrial use.

• Nickel & Exotic Alloys: For highly aggressive chemical environments, they provide:

  • Monel & Inconel

  • Hastelloy (C276/C22)

  • Duplex and Super Duplex Stainless Steel

  • Alloy 20

  • Titanium 

• Pressure Ratings: Commonly available in 150#, 300#, 600#, and 900# classes (up to 50 kg/cm² or higher on request).

• Temperature Range: Designed to withstand temperatures up to 300°C depending on the material and seal selection.

• End Connections: Options include Flanged (ANSI, DIN, JIS, BS standards), Butt-Weld, and Socket-Weld.

• Closure Types: Bolted covers for high-pressure safety or Quick-Opening covers for frequent cleaning and reduced downtime.

• High Flow Area: Designed with a large filtration area to ensure low pressure drops ($ΔP$).

• Durability: Robust construction with perforated baskets reinforced by wire mesh for mechanical strength.

• Ease of Maintenance: Baskets are easily removable with lifting handles for quick disposal of trapped debris.

To help you compare Falcon's basket strainers with industry standards, it is important to look at how they align with the global benchmarks for design, pressure, and testing.

Falcon typically manufactures its strainers to comply with ASME B16.34, which dictates the wall thickness and pressure-temperature ratings for valve bodies.

While strainers are not "valves" in the traditional sense, high-quality manufacturers like Falcon often use API 598 (Valve Inspection and Testing) as a reference for:

• Shell Test: Ensuring the body (CS, SS, or Alloy) can withstand 1.5 times the maximum working pressure without leaking.

Falcon uses ASTM (American Society for Testing and Materials) standards to ensure the chemical and mechanical properties of the metals used:

A critical comparison point is the $C_v$ value (Flow Coefficient). Falcon designs their baskets to have a high "Open Area Ratio," usually 6:1 (meaning the total area of the holes in the basket is six times the area of the inlet pipe), which exceeds basic commercial standards and reduces energy loss in your pumps.
