    Hayward Model 85 Y Strainers are heavy duty ones – engineered to stand up to the most aggressive of industrial and commercial applications... year after year. There is simply no higher quality Y strainer available ...at any cost.

    It may seem strange to discuss quality as a special feature of a basically simple Y strainer, however, it is appropriate when you consider the critical operational parameters often associated with Y strainers used in steam and gas applications, extremely high temperatures and high pressures. A Y strainer is a pressure vessel, its wall thickness can be analyzed and evaluated by different applicable standards. Hayward does not, and never will, compromise or stint on wall thickness. Every rugged Hayward Model 85 Y strainer is designed to stand up the most demanding real world applications. Hayward's over 75 years experience in manufacturing strainers ensures this.

    There is a tendency to trivialize quality, particularly when price becomes a dominant consideration. What this design consideration amounts to in non-critical, light duty applications is an extra element of safety, as well as longer, more dependable service. We extend our preoccupation with quality to each screen that is supplied with Hayward Y strainers. It should not come as a surprise to learn that those Y strainers, whose bodies are trimmed to a bare minimum for cost reasons, are equipped with screens that lack structural integrity and are poorly seated and sealed. Hayward 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.

    Hayward Model 85 Heavy Duty Y Strainers are available in iron, bronze, carbon steel or stainless steel for pipeline sizes from 1/4" to 20", with threaded, flanged, or socket weld connections. Do you have a unique application where a standard strainer just won’t work? Or…do you need special materials of construction, super high pressure ratings, special dimensions? Contact us. Our engineers will design and fabricate a strainer to match the requirements of the most complex applications.

  • Calculating Saturated Steam Pressure Drop

    Example:
    Pressure = 300 psig
    Flow Rate = 20,000 lb/hr
    Strainer Size = 4 inches

    1. Locate steam flow on Scale A.
    2. Follow vertical line to required pressure.
    3. Follow horizontal line to strainer size.
    4. Follow vertical line downward and read pressure drop on Scale C.
    5. Pressure drop equals 1.25 psi.

    Calculating Superheated Steam Pressure Drop

    Example:
    Pressure = 300 psig Flow Rate = 18,000 lb/hr
    Strainer Size = 4 inches

    1. Locate steam flow on Scale B.
    2. Follow horizontal line to superheat.
    3. Follow vertical line to pressure.
    4. Follow horizontal line to strainer size.
    5. Follow vertical line downward and read pressure drop on Scale C.
    6. Pressure drop equals 1.25 psi.

    Note: Use the superheat temperature value above the saturated steam temperature to obtain the point on this graph.
