The basket or screen is essential for the proper function of every Eaton Strainer. The strainer basket is designed to be both effective and durable and can be supplied in either standard and heavy-duty designs.  Eaton strainer baskets are available in two standard materials: Type 316 Stainless Steel and Monel. The materials provided cover nearly all corrosive resistance levels required.  A wide range of perforations and mesh provides removal of solids from 1/2" down to 40 micron. Custom fabrication for basket perforations is available.  Basket Construction Each style of strainer basket includes a perforated sheet that is induction welded to a rigid top ring and solid bottom cap. A handle is then welded to the inner diameter of the top ring to facilitate easy removal. Heavy duty baskets have reinforced strips welded along the seam.  Screen Construction Y strainer screens are rolled to for a perfect cylinder. The seam is induction welded. The screen seats are machined to specific dimensions and both the outer diameter and length of these screens are evaluated for tolerance.  Perforated Sheet - Specification All Eaton baskets are made of perforated sheet. The percentage of open area of a screen generally dictates the internal pressure drop that will be experienced. When selecting perforation size, it is best to balance the open area with hole arrangement and sheet thickness. The baskets are made using perforated sheets with round holes as this provides greater inherent strength and resistance to stress cracking. Open Area Perforated sheet can have an open area from 15% to 75%. In general, the larger the open area of perforated sheet, the thinner the sheet thickness must be. As holes are punched closer together to increase the perforated open area, the solid portion between holes distorts and becomes weak. Table A on page 27 describes the sheet thickness which is used to construct baskets and screens. Hole Arrangement Holes can be punched in a straight line or in a staggered pattern. Eaton baskets and screens have a staggered pattern which increases the open area, provides extra strength, and creates less pressure drop. Perforations Eaton baskets and screens are available in 1/32", 3/64", 1/16", 1/8", 5/32", 1/4", 3/8" and 1/2" perforations and in mesh sizes: 20, 40, 60, 80, 100, 200 and 325. However, over many years we have found that for general service there is one perforation for each size and type of strainer which is most popular. This is called the standard perforation and is the size furnished with the strainer unless another perforation is specified. Wire Mesh Specifications All Eaton strainers are available with woven wire mesh screens. Wire mesh provides smaller openings than can be obtained by perforating for very fine straining applications down to 40 micron. Eaton baskets and screens are made using monofilament mesh having equal wire size and wire count in both directions to produce square openings. Other types of mesh such as Dutch (or Hollander) are also available. Dutch weave has a greater quantity of wires in one direction and fewer wires of a larger diameter in the other direction. This creates a rectangular opening. As with perforated sheet, the best wire mesh selection is a balance of open area, wire diameter and type of weave.

Y Strainers are used in a wide variety of liquid and gas straining applications to protect downstream process system components in many industrial applications. Water handling applications—where it’s important to protect equipment that could be damaged or clogged by unwanted sand, gravel or other debris—commonly use Y strainers. They are also used in gaseous services such as steam, air, nitrogen, or natural gas. The strainers work really well for gaseous applications because the solids are usually small and clean out is not frequently required. The compact, cylindrical shape of the Y strainer is very strong and can readily accommodate the high pressures that are common in this type of service. Pressures up to 6,000 psi are not unusual. When steam is being handled, high temperature can be an additional complicating factor. A steam pressure of 1,500 psi will often be found at temperatures of 1,000°F. For cost effective straining solutions, Y strainers work well in a multitude of applications. When the amount of material to be removed from the flow is relatively small—resulting in long intervals between screen cleanings—the strainer screen is manually cleaned by shutting down the line and removing the strainer cap. For applications with heavier dirt loading, Y strainers can be fit with a "blow off" connection that permits the screen to be cleaned without removing it from the strainer body. Eaton Model 85 Heavy-Duty Y Strainer ¼” to 10”  Carbon Steel and Stainless Steel  Threaded, Flanged and Socket Weld Connections Eaton Model 85 Y Strainers are heavy duty filters— engineered to withstand even the most aggressive of industrial and commercial applications year after year. When you consider the critical operational parameters often associated with Y strainers used in steam and gas applications, it’s important to consider the quality of the vessel since it’s subjected to extremely high temperatures and high pressures. The wall thickness can be analyzed and evaluated by different applicable standards. Every rugged Eaton Model 85 Y Strainer is designed to stand up the most demanding real world applications. Eaton heavy duty Model 85 Y Strainers are furnished with high quality stainless steel screens that are carefully fabricated to fit the strainer body perfectly. This, coupled with the precision machined screen seat on the body of the strainer, protects against any bypass. Eaton Model 85 Heavy Duty Y Strainers are available in carbon steel or stainless steel for pipeline sizes from 1/4" to 10", with threaded, flanged, or socket weld connections. Features: Heavy Duty Construction  Compact Design  Bolted or Threaded Covers  Standard Stainless Steel Screens Available options: Perforated Stainless Steel Screens - 1/32" to 1/2", 20, 40, 60, 80, 100, 150, 200, 325 and 400 Mesh Stainless Steel Screens, Monel Screens.
