Temporary Cone, Basket & Plate Strainer

Temporary strainers are specially designed for the filtration of debris and for the protection of equipment and instrumentation during commissioning and start-up periods. The strainers are usually installed between a set of flanges without any modification to the surrounding pipeline for an initial period after a new plant has been installed. Temporary strainers are suitable for working at high pressure differences. The flow goes from the inside out, and the collecting debris in the basket can easily be removed.

PELTECH can tailor-made temporary strainers according to customer specifications. Standard construction is perforated screen or a single ply heavy wire mesh. Wire mesh can be added inside / outside of the strainer for finer straining capabilities but must ensure that the direction of flow is against the wire mesh with the perforated metal as a back-up.
 

Applications

 
Steam, water, oil, other liquid or gas where protection of pumps, maters, valves, and other similar equipment in a pipeline is required. These strainers are installed between flanges without any modification to the surrounding pipeline.
 

Features

 

  • Open Area Range (OAR) of 100% to 300% available, 150% OAR as our standard.
  • Additional stiffeners or cross bracing can be installed on both TC and TB type strainer to prevent collapse.
  • Both TC and TB type strainer can be inverted to obtain higher percent of open area.
  • Custom engineered designs available.

Construction

 
The Peltech style TC, TB, & TP Strainers are available in stainless steel, monel, hastelloy, and other alloys upon request. Screens are available perforated, mesh or mesh lined to meet specific media requirement.
 

Standard Screens

 
The Peltech style TC, TB, & TP Strainers are normally supplied with perforation 3mm diameter holes on 5 mm centers / pitch.
 

Sizes

 
3/4″ (20 mm) up to 24” (600 mm) as standard. Larger sizes are available upon request.
 

Screen Openings

 
If strainer is being used for protection rather than direct filtration, standard screens will suffice in most applications.

When choosing a perf or a mesh/perf combination, attention should be given to ensure overstraining does not occur. As a general rule, the specified level of filtration should be no smaller than half size of the particle to be removed. If too fine a filtration is specified, the pressure drop through the strainer will increase very rapidly.
 

Dimensional Data

 
Certified dimensional drawings are available upon request. Dimension shown are approximate. Unless otherwise specified, standard 3mm perforations, 150-300lb flanges & 150% open area will be supplied.
