Namdaran petrogas industries products are manufactured to meet all related specifiations and standards due to take sufficient steps through the consensus of whole big Family of our striver and potentate industrial society and also our country.


Flange basket strainers were initially developed for the petrochemical market. with continuous success it has become a standard product off shelf on most sizes. the unique quick-opening closure type and venting allow the field operator in a timely and safe fashion, to remove the basket for cleaning.an O-ring seal provides positive sealing of the cover.



The strainers can be designed to your specific application in carbon steel or stainless steel.1 ½” to 24” pipe sizes in 150# and 600#, 900#, 1500# and 2500# ANSI ratings are available.basket type can be fit to hold sufficient solids for the required time between clean-outs. flange sizes can be chosen to fit existing piping , or to achieve the required clean pressure drop. Maintenance reducing features include automatic flush and hinged cover, with or without davit assembly. numerous quick opening covers which conform to the ASME boiler and pressure vessel code are available too.

Optional Features

  • Single or multiple basket
  • Pressure gauge or differential pressure switch
  • Many codes and designs are available
  • Oversized body design to reduce pressure drop
  • Large sizes  and higher pressure classes are available as required.
  • Davit assembly
  • Custom baskets: at 316 : SS and special alloys
  • Back wash connection
  • High pressures up to 2500#
  • Special pert or mesh as small as 5 micron
  • Quick opening covers
  • Body materials of stainless steel and special alloy

1-T or BASKET type strainers

T/Basket -Type strainers are used to remove solids from flowing liquids and are ideally suited for process applications, water and utilities.
On large pipelines basket type strainers shall be used .They shall provide greater dirt holding capacity and easier access for removal of the strainer for cleaning. They normally have a higher pressure drop than simple Y type strainers. We are engaged in manufacture of an exclusive range of basket type strainers, which is made from high quality raw material sourced from credible vendors. These basket strainers are available in various sizes and colours as per clients’ specification. strainers are used to strain foreign matter from pipe line and provide inexpensive protection of costly pumps, meters, valves and similar mechanical equipment. These basket type strainers are available in a variety of materials. They can be specified for drinking water, cooling water, hot water system sea water. Just a few application in the chemical process industry, are Brine, Paint Heat Exchanger, condensers, fuel oil, Organic and Inorganic chemicals. Their utility, excellent finish and pricing are big attraction factors for our regular and new clients. The Machined Basket with gasket eliminates particle by-pass with the appropriate wire mesh. These basket type strainers can be used on strain particles as small as 5 microns.
Size : 2”to 24”. Higher sizes – engineered and manufactured to order.
Screen : Perforated plate with 3mm, 8mm or as per requirement.
Mesh : Options from mesh size 6, 40, 80, 100, 200 and 300μm
End Connections : Flanged ANSI, DIN, BS ; But weld, SW as per ASME standards / eq.
Rating : ANSI Class 150,300,600 standards. Higher pressure ratings also available.
Service : Strainers for both sour/ non-sour Services services available.


Anchor Flange1


Engineered by using Computional Fluid Dynamics, these are ideally suited for steam and condensate.
A correctly designed Y type - strainer is necessary, as otherwise the pressure drop becomes high. Often a low priced strainer is a result of undersizing - thereby leading to high pressure drop and pre-mature failure.
Size : ½” to 12” : carbon steel / Iron / Stainless Steel, Forged CS to ASTM A 105 ,2” to 24”
materials:A106, A 234 Gr WPB, SS304, SS316Higher sizes made to order.
Screen : Perforated plate with 3 mm, 8 mm perforations or as per requirement.
Mesh : Options from mesh size 6, 40, 80, 100, 200 and 300μm
End Connections: SW, BW, Flanged to various standards, Screwed
Rating : ANSI #150 UP TO #2500
Service : Strainers for both sour non-sour Services

3-Flat type strainer

Flat type strainers are designed for the efficient removal of solids in new pipeline start up service. 
They are compact and rugged and can be installed either vertically or horizontally.
They can be manufactured using any kind or wire mesh or perforated plate, in carbon and stainless steel or exotic alloys.
Strainers may be manufactured to any customer’s standard.
Strainers are designed to be installed between ANSI B16.5 flanges and meet FF, RF and RTJ facings.

4-Conical type strainer

This kind of strainers shall be used as temporary strainers in suction lines and is shown in IPS-D-PI-117.
Temporary Strainers are commonly used in multiple industry applications to capture and remove debris. prior to putting a pipeline into production service. Whether the line is new construction or an existing line that has been modified, these strainers remove the debris left in the piping from the fabrication and assembly activities. These economical and high quality strainers are manufactured from 316 stainless steel as standard and built to generally accepted industry dimensions to fit securely between multiple types of flanges. Standard dimensions provide 150% open area when using 1/8”perforated media. Longer lengths are available to provide increased open area. These temporary strainers are designed for short periods of operation and, after a nominal period of operation, they are normally replaced with a permanent strainer of a finer retention. fabricated strainer housings which can be customized to your exact needs. Variety of strainer material, perforation and mesh lining sizes, Higher pressure ratings and longer basket lengths are available. Ring Type Joint (RTJ) and Flat Face (FF) Flange configurations. Strainers can be designed for larger pipeline

5-Duplex (or multiplex)

A strainer usually consisting of at least two basket or element chambers separated by a valve (or valving) that permits continuous flow of fluid through one chamber while the other is accessible for cleaning. Our duplex type strainers are designed for applications in fluid handling systems, specifically, in cases where the flow cannot be shut down for basket cleaning. The duplex strainers are employed in such as cooling water, pumps, compressors, condensers, fire line, fuel lines lubricating systems, salt and fresh water systems, chemical process systems and positive suction head service. Their utility, excellent finish and pricing are big attraction factors for our regular and new clients. It features a single shaft drive to operate the flow diverted valves. Baskets are gasketed and stationed to prevent the passage of undesirable particles. The large capacity baskets provide generous open area ratio. The single basket design is easily and quick cleaned.
Duplex Strainers Size Range:      1" NB to 24" NB
Material of Construction:     Carbon Steel or Stainless Steel and as per request
Flanged Connections:         ANSI 150# or 300# up to 2500#
Design:             Butterfly or Ball Valve Duplex Arrangement
Cover:                 Bolted or Quick-Opening Hinged
Basket:             Perforated or Wire Mesh Stainless Steel
