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.
