IntroductionThe FDPP Model TSF Strainers aredevices installed in a pipeline to removesediment and debris from fluids. The FDPPModel TSF Strainers are designed for thefull ANSI pressure rating @ 100F that isshown on the strainer.

Straining is accomplished by directing the

fluid through sized openings in the Screen.Once sediment and debris is collected in theScreen, fluid flow is interrupted while theScreen is removed for cleaning.

Receiving, Handling and Inspection1. Unpack the FDPP Strainerand inspect

for damage occurring during transit.Report damage to the carrier. If theFDPP Straineris not installedimmediately, see Storage instructions.

2. Remove any preservatives with solventdampened cloths. Exercise care when

using solvent and follow solventmanufacturers instructions.3. Verify that the rating of the FDPP

Straineris greater than or equal to themaximum pressure & temperature of theinstallation.

4. Inspect Strainer by checking for andremoving any foreign or loose materialthat could be carried down stream whenfluid is introduced into the Strainer.

Storage1. Replace protective wrap, flange

protectors, etc. which may have been

removed during receiving, handling andinspection.

2. Store the Strainer indoors in a clean, dryenvironment.

Read all the information and instruc tionspr ior to instal ling & operating theStrainer. Failure to comply w ith these

instructions could result in bodily injuryor property damage.

Installation

CautionBefore Installation, review the application

and chemical compatibility of theprocess fluid to the mater ials ofconstruction of the Strainer.

1. Remove protective wraps, etc. beforeinstalling the Strainer into operation.

2. Position the Strainer in the pipeline sothat the fluid enters the connectionmarked IN, INLETor in thedirection of the Arrowcast into theStrainer. Always install the Strainer withthe blow-off (drain) in the lowestposition. Flow must be downward intothe inlet of the Strainer for satisfactoryoperation for vertical piping installations.

CautionTo lift the Strainer, put slings under theinlet, outlet connections .

3. Be sure sufficient clearance is providedfor easy opening of the cover (blow-off)and screen removal. Refer to the SalesDrawing for removal clearances.

4. For larger sized Strainers, support theStrainer firmly in the pipeline. Pipingmust allow for adjustments due to

Strainer connection tolerances. Strainersupports must prevent piping forces andmoments from acting on the Strainer.

5. Connect theFDPP Y-Strainerto thepipeline. On flanged Strainers, be sureto use the same type flange faces. Donot bo lt a raised face flange to a flatface flange!Be sure flange gaskets arein place and fasteners are tight. OnStrainers with other line connections,use standard piping practice wheninstalling the Strainer.

CautionFDPP Y-Strainers are not designed to beanchor suppor ts in the piping line. Besure to properly support process pipingon both s ides of the Strainer. Use care to

prevent p iping forces and moments fromacting on the strainer connections .Damage may occur to strainer ifimproperly connected.

6. Y-Strainers have no provision to accept

gauges. Pressure gauges near theStrainer inlet & outlet are required todetermine differential pressure acrossthe Strainer and cleaning frequency.Pressure gauges are essential for thesafe operation of the Strainer andshould be installed using standardpiping practices.

7. It is recommended that a compatiblevalve (and piping as needed) beinstalled in the cover (blow-off) for safequick clean out (normal blow-downcleaning).

CautionTo protect the operator when drainingand clean-out, the fluid must be piped toa safe area by using the valve stated inItem 7 above. This requirement is for allfluids and water (temperature above120F). The operator should wearappropriate protective equipment(goggles, gloves, vests, clothing, etc.)consistent with the process fluid forstrainer operation & servicing.

Start-Up1. Open Blow-Down valve to expel air from

the Strainer.2. Slowlyallow fluid to enter the Strainer.

CautionStart system GRADUALLY. Thiseliminates sudden shock to the Strainerand other equipment in the line. This isEXTREMELY important for steam service.

3. Close vent when air is expelled & fluidbegins to flow.

Shut Down Periods1. Slowly close the pipeline valves

upstream and downstream from theStrainer. Make sure these valves are

tightly closed.2. Relieve fluid pressure in the Strainer by

first opening the drain, then vent ifprovided. The Strainer must bedrained and internal pressurerelieved prior to cleaning. Proceed toclean the screen.

Directional Flow through a typical wye strainer

When to Clean the ScreenA differential pressure increase of5 to 10

psiacross the Strainer indicates that thescreen is full of debris and needs to becleaned.

CautionTo prevent screen damage, DO NOT

permit dif ferent ial pressure across the

strainer to exceed 20 psi.

Normal Blow-Down CleaningTo avoid shutting down the piping systemwhen possible, clean the screen of debris byopening the valve (See Installation, Item 7).Valve is to stay open until all debrishas been blown out from the screen. Thenclose the valve and resume normaloperation.

Screen Removal, Cleaning andReplacement

1. Follow theShut Down proceduresabove.2. When the Strainers internal pressure is

relieved, drain the fluid & loosenfasteners. Remove cover (blow-off).

3. Remove the debris laden screen. Note:Do not permit the screen debris to dry,as it would be difficult to remove andclean the screen

4. Invert the screen and wash out debrisby directing a stream of air or wateragainst the screen exterior. Use solventif strained fluid is fuel or a chemical.Follow manufacturers instructions whenusing a solvent to clean the screen.

5. Inspect screen at each cleaning forholes or tears. Replace as needed withgenuine FDPP screens. Always keepspare screens and gaskets in stock.

6. Inspect sealing surfaces and covergasket. Clean sealing surfaces andcover (blow off) seat. Replace cover

7. (blow off) gasket as necessary. Alwayskeep spare screens in stock.

Note: Model TSF Strainers have spiralwound gaskets. These gaskets must bereplaced using only a genuineFDPP part

each time the cover blow-off is removed

8. Place the cleaned / new screen squarelyon the seat in the cover (blow off).

9. Replace the cover (blow off and tightenthe fasteners uniformly.

10. Close the valve (if provided) and followthe Start-Up instructions
