T-TYPE FILTER

A range of simple strainers intended for service similar to temporary conical strainers but with their own element housing.
Specifically designed for location into a pipework system that cannot be split to extract the screen after commissioning is complete, or where the strainer is to be left installed as an additional permanent safeguard.
Units may be flanged or welded into the line and the screen is extracted through the branch opening.
Each unit is provided with a flanged cover.

Bathtub strainers may also be installed as a permanent strainer for removal of course particles or where contamination is minimal.

Sizes: 6″ – 24″ NB as standard.

Materials:

Body: Carbon steel, Stainless steel, 90/10 Cupro nickel alloy, 6MO High alloy stainless steel.

Screen: Mild steel, Stainless steel, or special alloy as requested.

 

WELDED STEEL SINGLE BASKET FILTERS


Welded steel single basket filters designed to meet customer requirements and covering full range of pipe line sizes.

Fabrication design allows options of bolted or quick release covers to be selected and easy adaptation to suit customer requirements for materials and design conditions etc.

Sizes: 6” and 60” NB, flanged or butt weld connections.

Materials: Fabricated from carbon steel and standard or stainless steel to special order, all fitted with baskets and inserts as required.

Design codes: ANSI B.314., ASME VIII or BS.5500.

 

HI-FLOW FILTERS

Strainers designed and manufactured for specific duties – especially high fluid velocities (flow rates) or low pressure loss requirements.
Used in pump suction duties, turbine meter protection, offshore etc.
36” Hi-Flow Filter
Crude oil pipeline in the Middle East
Custom designed for low pressure loss and high velocity applications such as pump suctions or meter protection duties where contamination levels are relative low.

A straight through flow pattern and the use of vertical pleated screen gives resultant clean pressure drops much lower than conventional bucket type basket filters.
Lightweight design can give significant commercial benefits especially on applications requiring high design pressures or exotic materials.

Size: 4” to 60” Bore (design pressures and flange ratings to suit requirements).

Materials:
Carbon steel l Stainless steel l special Cupro nickel alloy, 6Mo.
Filtration Screen material: lMild steel lStainless steel l Monel.

 

AUTOMATIC BACKFLUSHING

A range of fully automatic backflushing filters covering all sizes and pressures.
Sizes: From 6” upwards of any pressures above 30 PSIG.  Filtration from 5mm to 50 micron.
Typical applications include power station applications, ACW, Boiler Feed and seawater filtration.
Materials:  Welded construction allows manufacture in any material from carbon steel with lining to special alloys.

HORIZONTAL GAS FILTER

For larger capacities and pipe sizes the Type H is a welded steel horizontal filter that may be custom designed or is available as standard with quick release closure and designed for working pressures up to 100 Bar – 1440Ib/in².
Supplied with either two or three triple length elements servicing time is minimised.
The welded construction enables inlet and outlet nozzles to be radial positioned to suit site pipe work.
Filter closure may be bolted although generally a quick release closure is utilized.
Designed for high-pressure systems requiring a filter of the highest quality and specifications.

LIFE CYCLE COSTS

Plenty Process Filters offer low cost disposable fibreglass elements. Inner & outer support baskets are made of Stainless Steel & are cleanable & re-usable

GAS FILTER SEPARATORS

A range of specialised units used to separate liquids from gases.  Each unit is built to suit specific operating conditions.
Knock-out pots – simple method for removing larger size droplets and liquid slugs.
Vane separators – remove smaller liquid droplets.
Filter separators – two stage separators using coalescer  elements and vane elements for very efficient removal of fine droplets as well as solids.
Multi cyclone separators – remove large quantities of solids and liquids by centrifugal force in multi cyclone bundles.

HORIZONTAL SEPARATOR FILTER

The Plenty Vertical Filter Separator will remove 100% of all droplets 8-10 microns and larger and 99.5% of all droplets ½-8 microns in size.
It will also remove 100% of all solid particles, 3 microns and larger 99% of all particles ½-3 microns in size.
These operating efficiencies apply over the entire flow range from maximum design down to virtually zero flow.
The first stage of the filter separator consists of a number of glass fibre coalescer /filter elements through which the wet gas passes.
The small liquid drops carried in the gas stream are trapped within the glass fibers of the element and coalesce to form drops 100 to 200 times larger than the original size.
These drops pass through the element wall and are carried forward by the gas stream to the second stage vane type separator.
The second stage consists of a vane type impingement separator, which operates exactly as described for vane separator.

Vanes & Cyclones
Typical Cyclone Bundle. (below)
Gas enters cyclone tubes in tangential slots creating spinning action.  Contaminate is thrown to outside and falls and only clean gas enters central tube and exits at top.
Typical Vane Unit. (Above)
Gas flows through vanes (left to right) and moisture collects and runs down to bottom section which has single outlet to the holding sump.
