INTRODUCTION

A simplex strainer is a device installed in a pipeline to remove dirt and other unwanted debris from fluids. Straining is accomplished by directing the fluid through sized openings in a basket. Simplex strainers are installed where fluid flow can be interrupted while the basket is removed for cleaning. Simplex strainers are designed to withstand the rated pressure of the piping sys tem.

RECEIVING, HANDLING, AND INSPECTION

Inspect strainer after unpacking for damage in curred during transit. Report any damage to the carrier immediately . If the strainer is not to be installed imm ediate ly , store indoors in a clean, dry environment.

Remove preservative with a solvent dampened cloth. Exercise care when using solvent.

Replace strainer cover a nd yoke and ti gh ten T-bolt. The basket is held in place by pressure of the cover on the basket handle . If the basket is l oose, spring the h and le to a higher position to insure grea ter compression when the cover i s seated.

INSTALLATION

Position the strainer in the line so that the fluid enters the connection marked “ inlet."

Check to be sure the rated pressure and tem perature on the strainer nameplate is not less than the maximum pressure and temperature of the installation . The rated pressure shown on the nameplate is the maximum pressure , including shock, at which the strainer may be operated.

Remove cover by turning T-bolt counterclockwise to release yoke, swing yoke clear of cover and remove cover . Check for and remove any for eig n or loose materials that could be carried downstream when fluid is introduced into the strainer.

CAUTION: Lift strainers with slings under the inlet and outlet connections. DO NOT lift the strainer by the yoke screw located on the strainer cover.

Be sure sufficient headroom is provided for easy removal of cover and basket.

Support the strainer in the line as follows :

4" size or under:

Use pipe supports under the process piping near inlet and outlet connections. Use care to prevent bending and expansion forces from acting on the nozzles.

5” size or larger:

Support on concrete or steel pads.

Connect the strainer to the line . U se same type flange f aces .

For example: Do not bolt raised face flanges to iron flat face flanges . Iron flanges must be flat face with full face gaskets.

Installation, Operation & Maintenance Manual

OPERATION

Cast strainers are subject to face to face variations due to shrinkage and machining tolerances.

Prefabricated piping systems must allow adjustment at the strainer connection .

Open vent, if strainer is so equ i pped (See Fig . 2), to e x pel air from the strainer.

Slowly introduce fluid to be strained by opening the outlet valve first , followed by opening the inlet valve .

If strainer has threaded connections follow proper threaded specifications. If strainer has weld connection follow proper

ANSI weld specifications.

Be sure flange gaskets are in place and fastene r s are tight.

It is recommended that the drain plug be removed and drain valve be installed at the bottom of the basket chamber as shown in Fig. 1 .

CAUTION: Start system GRADUALLY. This eliminates sudden shock to the strainer and other equipment in the line.

Close the vent when air is expelled and fluid begins to flow .

SHUT-DOWN

Tightly close valves on the inlet and outlet connections or the strainer . Open vent (See Fig . 2) and/or drain valve (See Fig .

1) to relieve liquid pressure in the strainer. must be piped to a safe discharge point to protect the operator. (See Fig.2). Wear protective clothing, which includes gloves, vests, and goggles when handling dangerous fluids.

CAUTION: A vent is required when fluids other than water and with temperatures in excess of

120° F are to be handled by the strainer. The vent

Pressure gauges near the strainer inlet and outlet are recommended. Cleaning frequency is determined by the pressure drop across the strainer.

CAUTION: DO NOT loosen cover while there is liquid or air flow from the vent.

BASKET REMOVAL

Follow shut-down procedure .

When pressure is relieved , loosen T bolt. Dra i n fluid through bottom drain to a level below the basket seat.

Swing yoke clear of cover and r emove cover and d i rty basket.

BASKET REPLACEMENT

Place new or clean basket squarely on the basket seat. Be sure basket handle is sufficiently high to be compressed by strainer cover .

Inspect 0-ring and seal surface : Clean seat or replace cover 0ring as necessary. Always keep spare 0-rings in stock .

Replace cover, swing the yoke over the cover and make full contact with the yoke stud . Tighten the center T-bolt. If strainer is on suction service, fill basket chamber from outside source before install i ng cover.

Follow start-up procedure.

BASKET CLEANING

When to Clean

Clean basket when there is a 5 psi increase in pressure loss across the strainer .
