How to SelectThere are three important componentsin selection:

1.Design and operating pressures andtemperatures - look at the curves inFigure 2. Select the strainer rating that meets both the design and theoperating requirements.

2.Flow rate and pressure drop - select a strainer pipe size that will yield apressure drop of 11/2 psi or less.This will accommodate increases inpressure drop due to dirt or alternatescreens without causing the screen to rupture.

3.Look at the Selection Table on page 4and pick the strainer series that meetsthe conditions of 1 and 2 above, and iscompatible with the flowing medium.

InstallationStrainers should be installed upstreamof pipeline equipment to protect againstdamage from solid particles of dirt,chips, scale, packing shreds, pipesealants and welding debris.

The strainer should be fitted with a pipenipple in the cap or cover and a fullported straight through valve (e.g., gateor ball).

Install the strainer in a horizontal orvertical line with flow in the direction of the arrow.

For freeze protection, install the straineron its side or upside down in a horizontalline or vertically to assist in draining theblowdown line and strainer cavity.

Inspect the strainer regularly. Clean thescreen before it becomes more thanone-third clogged. Pressure gagesbefore and after the strainer will indicateexcessive pressure losses due toclogging.

Water flow vs. pressure drop

Flow rate, m3/hr.



Pressure drop through YarwayWye strainersIn the application of Wye strainers themost frequent concern is pressure drop.Since the strainers can have a variety offluids passing through them, there are avariety of equations and conditions thataffect the flow.

Our objective is to present methods for calculating pressure drops acrossYarway’s Wye Type strainers. Thecalculations are based on a series offormulas and the use of a Cv, and coversliquids, steam and gases.

The following assumptions are made:

1. Control valve equations and the use ofCv is appropriate.

2. For liquid flow:

• Flashing and cavitation are notpresent.

• There is no significant change indensity.

• Flow is fully turbulent and viscosity is not a significant factor in thecalculations for pressure drop.

3. For steam, gas and air flows, pressuredrops are not critical, and a change indensity (if it occurs) is not significant.

The examples of pressure dropcalculations are based on new, cleanstrainers. If clogged screens are asignificant concern, follow the footnoteunder Figure 1.

Determine the strainer CvThe first thing to determine is thestrainer Cv. This can be obtained fromFigure 1 the water flow vs pressure dropcurve where Cv = gpm when thepressure drop is one (1) psi.

Example:

What is the Cv for a 3” M800 YarwayWye strainer?

Solution:

1. Enter the left, vertical axis at one(1.0) psi.

2. Move horizontally to the right untilyou reach the 3” M800 curve.

3. Then, move vertically down andread 150 gpm.

4. Answer - The Cv for a 3” M800 is150.

This solution is for water; specific gravityis approximately one.

Liquid flow with specific gravitynot equal to oneExample:

What is the pressure drop if the fluid iskerosene, flowing at 150 gpm for a 3”M800 strainer?

Solution:

1. Enter a table of various liquids.

2. Find kerosene with a specific gravityof 0.82.

3. Solve the equation

Equation 1:

∆ PI = G ( V I )2

Cv

= (0.82) ( 150 )2= 0.82 psi

150Where:

∆ PI = Liquid/pressure drop, psi

VI = Liquid flow, gpm = 150(previous example)

Cv = Strainer Cv = 150 (previousexample)

GI = Specific gravity of liquid. Forkerosene GI = 0.82

Liquid flow, viscosityconsiderationWith the turbulent flow, the pressuredrop equations are independent ofReynolds Number. When viscous fluidsare present, Reynolds Numbers can bechanged to the point where Laminar flowis achieved. The use of Equation 2 and 3determines if the flow is turbulent. If it is turbulent, Equation 4 can be used.If Reynolds Number is less than 4000,Equation 4 will predict a greater thanexpected pressure drop.

Equation 2:

Re = 3160 VIvd

Re = Reynolds No.

VI = GPM

v = Kinematic viscosity, centistokes

Equation 3:

VI =Cv ∆Pv

GI

GI = Specific gravity of liquid

∆Pv = Viscous fluid, pressure drop, psi

d = Pipe I.D. inch

Combining Equation 2 and 3 andassuming Re = 4000 minimum forturbulent flow, and “d” is a controllingfactor for the strainer:

4000 = (3160)( Cv ) ∆Pv

vd GI

or

Equation 4:

∆Pv = (1.6023)(GI) (vd)2

Cv

Example:

Assume the same 3” strainer flowingkerosene. The specific gravity is 0.82,but the kinematic viscosity is 2.69. PipeI.D. is 3.068 inches. Using Equation 4:

∆Pv = (1.6023)(0.82) (2.69 x 3.068)2

150

= .004 psi minimum for aReynolds Number of 4000 to maintain turbulent flow.

This means that if the pressure drop andReynolds Number are too low, Laminarflow may result and the influence ofviscosity can alter the results. Theapproximate Reynolds Number for 150 gpm flow in the example is:

Re =(3160) (150)

(2.69) (3.068)

is over 57, 400 from equation(2) and the ∆Pv approaches0.82 from equation (3).



Gas and vapor flowThe flow of gases and vapors is more complicated than liquid flow.This is due to changes in density. If pressure drops are too great,the nature of the gas or vapor changes.

These equations are assumed to apply:

In the above, it is assumed that the control valve formulas for non-critical steam and gas flow are applicable.

∆Ps = Pressure drop across strainer, steam psi

∆Pg = Pressure drop across strainer, gas, air, etc.

P1 = Strainer inlet pressure, psia

W = lb/hr steam flow

Q = SCFH gas flow

Ts = Degrees F superheat above saturation

T = Degrees R gas temperature (F7460)

G = Specific gravity, gas (air = 1)

Saturated steam flowLet’s assume we have a 2” steam line. Steam flow is 2000 lb/hrand the steam pressure is 100 psig, saturated. What is thepressure drop through the 2” Yarway 921 Wye Strainer?

From Figure 1 we see that the 2” 921 has a Cv equal to 55.

P1 = 100 psig = 115 psia

W = 2000 lb/h

Cv = 55

Ts = 0, because the steam is saturated

Superheated steamAssume the same strainer and conditions as for saturated steam,except the steam temperature is 500°F.

We use the same equation except

Ts = 500-338

Ts = 162°F, degrees superheat

500 = Steam temp, F

338 = Sat. temp, F for 100 psi

GasesIf we keep the same strainer, but now consider natural gas flow at50,000 SCFH and at a temperature of 100°F.

Cv = 55

P1 = 115 psia

G = 0.667

T = 460 + 100 = 560R

Q = 50,000

Steam (saturated or superheat)

Equation 5:

∆Ps = P1 - (P1)2 - (W) (1 + 0.0007 Ts) 2

(2.1) (Cv)

Gases (including air)

Equation 6:

∆Pg = P1 - (P1)2 - (G) (T) (Q) 2

(963) (Cv)

From Equation 5:

∆Ps = (115) - (115)2 - (2000) (1 + 0) 2

(2.1) (55)

= 1.31 psi drop

The steam pressure drop is calculated to be 1 to 11/2 psi.

∆Ps = (115) - (115)2 - (2000) (1 + 0.0007 x 162) 2

(2.1) (55)

∆Ps = 1.63 psi

The superheated steam will produce a pressure dropnearly 1/4 more than the saturated condition.

∆Pg = (115) - (115)2 - (0.667) (560)50,000 2

(963) (55)

= 1.46 psi

Pressure drop is approximately 11/2 psi.



Easily Removable Screen CapsStraight threads permit easy removal from the strainer body when the screen must becleaned, and assure proper alignment of the screen when re-assembled. Machinedfaces and “spark plug” type gasket provide a good joint without excessive tightening. On21/2” and 3” strainers, four bolt covers are used instead of threaded screen caps.

Screens

Perforated screen - easy to clean, lesssusceptible to clogging.

Dutchweave screen for applicationsrequiring retention of small particles.

Two types of screens for a range of process conditionsPerforated stainless steel or Monel® in a wide range of opening sizes with high openarea ratios for low pressure drops. Fine mesh stainless steel Dutchweave screens alsoavailable. Both types provide greater mechanical strength than ordinary square mesh.Machined recesses in the body and cap assure the proper fit of the screen and itsalignment in the body.

Unibody® PlusIn-line renewable traps for tracingand steam line drips

The UniBody Plus line of steam trapsincludes five different types of in-linerenewable traps: “zero steam loss” disc,variable orifice (piston), orifice and thepatented cyclic, fail open thermostatic.Two types of trap bodies with eitherthreaded or socketwelding endconnections are available in the UniBodyPlus line: a trap body only or a completetrapping station with integral “Wye”strainer or blow-off valve. Once installed,the body stays in-line. Simply install alow torque renewal trap capsule.

Thermodynamic and thermostatictraps for process applications

Process heat exchange applicationsrequire traps that purge large volumes of air, provide fast warm-up and respondquickly to operating conditions. TheSeries 151, 40/40D and 731/741 withrenewable internals have proven theirability to meet these applicationrequirements.

In addition, these traps all feature smallcompact designs that are easy to installand maintain which results in reducedcosts. The traps are self-draining andunaffected by freezing.

Typical process equipment using thesetraps include evaporators, air heatingcoils, autoclaves, shell and tube heatexchangers, and submerged coils.
