Temporary Strainer

To start with temporary strainers are generally used at startup of pipelines to filter larger debris and foreign objects that may be present during construction and startup. Furthermore, temporary strainers may be conical or truncated. Hence, flow and media determines the direction of the strainer. In addition piping systems usually need industrial strainers.

In brief, temporary strainers are mostly used for start-up of new or revamped piping systems. Therefore, temporary strainers will prevent construction debris from causing damage to downstream equipment. Also the screen cone is welded around the entire circumference of the flange ring. Thus provides strength and prevents unwanted bypass.

Size: Range in sizes from 1/4” to 60” nominal pipe size as standard.
Open Area: Range in open area of strainer to cross section area of the pipe from 100% to 300% as standard.
Material Thickness: Gauge of strainer material ranges between 22 to 11 depending on hole size.

Basket type strainers protect equipment by removing solids from liquids and other piping systems with the use of a perforated or wire mesh straining screen in a vertically oriented chamber.

Perforation: Perforation hole sizes range from 1/16” to 1/4” as standard.
Type of Material: Materials include carbon steel, various grades of stainless steel and alloys.
Flange/Facings: Temporary strainer support rings can be made to work with standard flanges. For example raised face flanges, and ring type joint flanges.
Welding: Resistance welding, TIG and Oxyacetylene.
Liners/Covers: Available for small particle removal 200 through 10 mesh carbon steel; stainless steel, etc.
Straight Flow – Mesh on inside.
Reverse Flow – Mesh on outside.

Cone type strainers can be temporary and put in pipelines to protect equipment from debris and particles.

In general, when ordering specify:

  • First and foremost pipe size.
  • Then pressure rating/flange rating.
  • Next perforation or mesh size.
  • Also material.
  • As well as style – Cone, Basket, etc.
  • In addition to the direction of flow – straight or reverse.
  • Lastly the percentage of open area or length.
Plate type strainers involve a flat plane of mesh that stretches perpendicular to the system's flow.

Conical Strainers

To begin with conical strainers are in the shape as a cone. Hence why they are called a cone strainer. A conical temporary strainer is a perforated devices of perforated or woven mesh to catch particles in a pipeline. Furthermore, Dannenbaum LLC can help with temporary conical strainers.

However, these are usually temporary and put in pipelines to protect equipment from debris and particles. Also conical temporary strainers are shaped like a cone, or witch’s hat.

Moreover, a conical temporary strainer can catch particles down to .001 inch in diameter. In addition cone strainers have little pressure drop, and can be removed after startup, and the debris is evacuated.

And the sizing of Conical strainers is important to ensure the strainer screen can block particles that could damage equipment.

Basket Strainers

AD Muller2020-09-18T16:27:30+00:00

 

Basket Strainers

To begin, basket strainers protect equipment by removing solids from liquids in piping systems with the use of a perforated or wire mesh straining screen in a vertically oriented chamber. Therefore, strainers are important components of piping systems to protect equipment from particles that may be carried by the process fluid. And basket strainers have more debris holding capacity than Y strainers. Then they usually have less of a pressure drop, which is why they are ideal in liquid applications. Additionally strainers are usually supplied in iron, carbon steel, bronze, or stainless steel. And iron is used the most because it costs the least and has good corrosion resistance in water.

Material

Firstly carbon steel is used in basket strainers where higher temperatures, or concern with thermal or mechanical shock is an issue, which makes them popular in the oil and petrochemical industries. As well as bronze handles thermal and mechanical shock better than iron and is better in some corrosive applications. And stainless steel is needed in basket strainers where corrosion could be an issue. And is widely used in the chemical, food, and pharmaceutical industries. In addition during system start-up and flushing, strainers may be placed upstream of pumps to protect them from debris that might have been left in the pipe.

 

Industrial Basket Strainers are inline baskets that are used to collect mater or sludge from continuing through a pipeline. Valves can be attached to the bottom to exit and clean the basket.

Fabricated Duplex Strainers

AD Muller2020-09-22T17:28:16+00:00

 

 

Double Basket Strainer

Fabricated duplex strainers (double basket strainers) are used when the flow or process cannot be shut down and must continue to flow. Thus, duplex strainers allows you to shut one basket for cleaning while the other is still in operation. Moreover, double basket strainers are normally used where larger amounts of trash/solids need to be removed. The screen is in the shape of a basket and removed from the top of the fabricated duplex strainer. Fabricated duplex strainers can come with a blow-off connection for manual or automatic cleaning.

 

Duplex Strainers

A main application for duplex strainers is in fluid handling systems such as cooling water, fire lines, hydrocarbon, fuel lines, fresh water, pump suction, compressors, and lubrication systems. Fabricated duplex strainers body can be casting or fabricated material. Always check material compatibility with the process. Screens should be sized to meet the perforations, and mesh requirements.    

Fabricated duplex strainers gaskets, end connections, and blow-off connections, should be part of the sizing equation. Fabricated duplex strainers are a industrial strainer. Contact us for more infromation or for a quote.

The standard Tee Strainer is constructed of Carbon or Stainless Steel material. We can supply t-strainers in almost any material. Including fabricating these t-strainers from Chrome-Moly material. Other end connections and accessories are available.

INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR T STRAINERS, T-STRAINERS, TEE STRAINERS

• After pressurizing, inspect cover and other joints for leakage. Gasket replacement or cover tightening is necessary if leakage occurs.
• If the required filtration is not taking place, ensure the screen is installed in the correct position, that being flush to the screen seating
surfaces.
  • Ensure all machined surfaces are free of defects and that the inside of the t-strainer is free of foreign objects.
  • For horizontal and vertical pipelines, the t-strainer should be installed so that the blow-down drain connection is pointed downward.
  • For flanged end t-strainers, the flange bolting should be tightened gradually in a back and forth clockwise motion. Threaded end t strainers should use an appropriate sealant.
  • Once installed, increase line pressure gradually and check for leakage around joints.
  • If the t strainer is supplied with a start-up screen, monitor pressure drop carefully. For maximum efficiency, determine the length of time it takes for the pressure drop to double that in the clean condition. Once the pressure drop reaches an unacceptable value, shut down line and follow the “Screen Removal Instructions” above. A pressure gauge installed before and after the t-strainer or t strainer in-line will indicate pressure loss due to clogging and may be used to determine when cleaning is required.
SCREEN REMOVAL INSTRUCTIONS FOR T STRAINERS, T-STRAINERS, TEE STRAINERS
  • Drain piping.
  • Vent line to relieve pressure.
  • Loosen cover and open to access screen.
  • Remove, clean and replace screen in original position (Note: In some instances, a high pressure water jet or steam may be required for
    effective cleaning).
  • Inspect cover gasket for damage. If necessary, replace. (Note: If spiral wound gaskets have been used, they must be replaced and can not be used again).
  • Tighten cover. The tee strainer, t-strainer, t strainer, is ready for line startup. CAUTION SHOULD BE TAKEN DUE TO POSSIBLE
    EMISSION OF PROCESS MATERIAL FROM PIPING. ALWAYS ENSURE NO LINE PRESSURE EXISTS
    WHEN OPENING COVER.
WARNING: This product operates in pipelines or with equipment that carries fluids and/or gasses at

Y Strainers

AD Muller2020-10-19T03:37:33+00:00

Y Strainers

Y (Wye) Strainers also known as a Y Strainer gets its name from its configuration and is most commonly used in pressurized lines, gas or liquid. They are an industrial strainer and can also be used in suction or vacuum conditions. Furthermore, under the right condition you can clean out the Y strainer without removing the screen. Firstly solids need to flush easily from the screen. Secondly, fluids need to be released. Therefore, a blow-down valve on the drain will allow flow to continue without removing the screen. By definition a strainer provides a means of mechanically removing solids from a flowing liquid. Y Strainers do this by utilizing a perforated metal, mesh or wedge wire straining element.

Y-Strainers

Y-Strainers can be used in either a horizontal or vertical position while most basket strainers are designed for horizontal or slightly inclined piping applications. You must pay attention to the orientation of the chamber which collects debris and the drain (blow-down) connection of the Y-Strainer. The strainer must be installed so that it is in the lowest possible position

Y-Strainers are used to protect pipeline systems by filtering out small debris through the strainer’s internal basket or screen. The custom made basket can be sized with a mesh to catch smaller objects.

Y-Strainers remove items from pipelines. They protect pumps and other equipment. Being cost effect in most applications, it is a good idea to use them as much as needed. Y-Strainers are used in chemical processing, petroleum, power generation, marine, and etc… Y-Strainers are best used when a clean-out is not needed often. They are commonly used in high pressures.

Y-Strainers are furnished standard with drain connections and pipe plugs. most ordinarily, Wye strainers are fitted within the field with nipples and drain valves to allow the strainer screen to be cleaned while the system remains in process. By opening the drain valve while the system is struggling , the debris trapped within the screen is “blown” through this connection helping to scale back system shut-downs for maintenance and cleaning.

Y-Strainers strainers are offered in both domestic and foreign castings with a good sort of straining options for nearly any application.

Y-Strainers are available in forged iron , Ductile Iron, Bronze, Nickel aluminum bronze , Carbon Steel, chrome steel , and a spread of specialty metals including Alloy 20, Hastelloy C276, Monel, Chrome-Moly, and Titanium to face up to thermal or mechanical shock and corrosion.

Cast Wye strainers and in fact are available in most materials

Pressure ratings are ANSI 125# through ANSI 2500#. Standard body materials offered are forged iron , Ductile Iron, Cast Steel, chrome steel , Chrome-Moly and Bronze. The Wye strainers are equipped with a detach port. A valve are often fitted to flush debris that’s easily removable from the screen and exhaust to atmosphere or a drain system. This feature allows for straightforward cleaning without interrupting the method . Various Perforations, Mesh or Perforation Mesh combinations or Wedge Wire screens are available to satisfy your process requirements. we feature an outsized inventory so you do not need to depend upon us for your pack up or construction delivery requirements. inspect our full line of strainers or for more information contact us immediately.

Wye Strainers

APPLICATIONS

Steam, water, oil or gas where protection from foreign matter in a pipeline is required.

CONSTRUCTION

The Wye strainers are constructed from rugged 316 stainless steel castings and are machined to exacting specifications. These bodies have drilled flanges that are in accordance with ASME B16.5. All flanges come standard with back-faced bolt holes.

FEATURES

Wye strainers features a machined groove in both the body and cover for proper screen alignment. Furthermore, to ensure accurate reseating when servicing is required. The gasket is 304 stainless steel spiral wound. Thus it is compressed between the body and cover (for maximum strength and durability). Moreover, they are designed for high pressure and high temperature service. Wye strainers have cap screws and can be furnished with a stainless steel blow-off plug upon request. Blind covers are available upon request.

SCREENS

Wye strainers standard perforated 304 stainless steel screens are spot welded along the seam for maximum strength. Different size perforations and meshes are available in stainless steel, monel, and brass to meet specific media requirements. If media is not indicated, screens for steam will be supplied.

SELF CLEANING

Self cleaning is accomplished by opening the valve or drain plug connected to the blow-off port.

 

Wye strainers take their name from their configuration. they’re most ordinarily utilized in pressurized lines, gas or liquid, but also can be utilized in suction or vacuum conditions. they’re intended for applications where small amounts of solid particulate are expected, and where clean-out are going to be infrequent. If solids will flush easily from the screen, and fluid are often exhausted to atmosphere, a blow-down valve on the drain port will allow clean-out without removal of the screen, and without interrupting the method flow.

Wye strainers threaded strainers in forged iron and Cast Bronze feature a machined, tapered seat which ensures an ideal fit the removable, chrome steel screen. All sizes come complete with NPT blow-off with plug, which may get replaced with a valve for on-line blow-down of particulate.

Wye strainers take their name from their configuration. Wye strainers are cast in sizes ¼” – 24″ with Threaded, Socket Weld or Flanged End connections. Strainer are your most economical choice for giant debris removal. they’re most ordinarily utilized in pressurized lines, gas or liquid, but also can be utilized in suction or vacuum conditions. Y Strainer has the advantage of having the ability to be installed in either a horizontal or vertical position. However, in both cases, the screening element or “leg” must get on the “downside” of the strainer body in order that entrapped solids are often properly collected and held for disposal.
