Basket Strainers

Basket Strainers

Often referred to as Simplex or Mono Inline Basket Strainers, these are mechanical devices for the efficient removal and retention of solids and other foreign material from flowing fluids and gases. They do this by means of a strainer basket housed within the unit. Basket strainers incorporate larger filtration areas than ‘Y’-Type strainers and similar strainers on the market and thus provide minimal pressure losses, improved flow rates, greater dirt holding capacity and longer service times.

GFSA basket strainers can be supplied as either cast or fabricated units with a choice of three different types of closure: bolted, quick-release and quick release safety interlock, which meets the requirements of ASME VIII UG-35 (b) and Gas E13 specifications. Quick release closures are supplied as standard and provide quick and simple access for maintenance without the need for special tools.

Basket strainers are used in a vast range of applications where flow can be interrupted to allow the removal of the basket for periodic cleaning. They are usually mounted horizontally into the pipeline, however on fabricated units, line connections can be orientated to suit customer requirements. Minor modifications can also be made to enable the installation into downward flow vertical pipelines.

The central part of the unit is the strainer basket which removes and retains the harmful contamination. The basket is secured via a spring loaded handle which is compressed by the strainer cover. Baskets are manufactured from perforated plate and, for finer degrees of filtration, baskets are lined with mesh linings which can be either permanent fixtures or removable.

For fine filtration down to 1 – 2 micron, special basket assemblies can be provided where only the middle insert needs to be replaced as required. Baskets can be supplied in high quality Stainless Steel which is cleanable. As with all GFSA strainers, great emphasis is placed upon the filtration area available in each unit. GFSA strainers exhibit greater filtration areas than similar strainers on the market in order to provide maximum efficiency and economy. For even greater filtration areas, pleated baskets can be provided.

Size range: From ½” (15mm) to 12” (300mm) n.b. for the cast range and up to 36” (900mm) n.b. for the fabricated range.
Pressure ratings: Up to 2500LB ANSI rating.
Connections: Inline and available as screwed and socket-weld up to 2” (50mm) n.b., together with butt-weld and flanged.
