Steellong provide a whole range of perforated stainless steel temporary strainers which are mainly are designed to remove foreign particles from pipelines.They are produced completely of high-grade stainless steel in fully welded design. They are made of perforated plate or of perforated plate with fabric filter medium related to the  filter rate. The compact design guarantees a minimal space requirement. It is available in filter rates of 250, 500, 1000 and 5000 µm.

Conical Strainers are very low cost protection for process equipment against damage causing contamination present during Start-up and Commissioning. Conical strainers are for temporary use and thrown away after initial cleaning of the system. The down side to a Conical Strainer is they are sandwiched between two flanges therefore requiring an accessible section of pipe, such as removable spool pieces. Conical strainers can be manufactured in a range of different configurations to suit your specific requirements, size, length, filtration level, identification marks, supports…etc.

Material selection is determined primarily by application.  High heat and caustic or corrosive environments often require the use of stainless steel filters and strainers.  Stainless steel filters are common in chemical, food, marine, and pharmaceutical  applications.  When selecting the material, be sure to include as much information as possible regarding the operating environment for the metal filter or strainer and we will make recommendations based on your specific needs.

Stainless steel filters and strainers offer a high degree of corrosion resistance.  Many of the process industries that use metal filters and strainers introduce moisture or caustic fluids to the filtering element.  For these reasons, stainless steel is a natural choice.  Thanks to advances in welding technology, many of the filters and strainers that were historically made from Monel are now constructed with cost effective, long lasting stainless steel.  Roughly 90 percent of the metal filters and strainers manufactured by Steellong are constructed with stainless steel for these reasons.

Metal strainers are manufactured from wire mesh, perforated metal, or expanded metal, and are often placed in-line with process piping to remove larger particulate matter and contaminants that may damage pumps, valves and other process equipment. Metal strainers can also be used to separate, or screen one substance from another. Typical applications include food processing, pharmaceutical, chemical, hydraulic, and general industrial applications.

Metal strainers come in wide range of configurations, including basket or simplex basket, duplex basket, in-line, tee type, and y-strainers. A simplex basket metal strainer is used when a temporary line shut down to clean or change baskets is practical. Duplex strainers eliminate the need to shut down the process line for cleaning; when one strainer basket becomes full and clogged, the flow is simply switched to the other side, allowing the line to run continually. In-line strainers, often utilized in sanitary applications, are typically positioned with the basket parallel to the line of fluid flow. Tee type metal strainers are similar to duplex strainers, allowing for quick basket replacement and ease of cleaning. Y-strainers are often used in process pipelines to protect pumps, meters, control valves, steam traps, and regulators.

Metal strainers possess design characteristics which make them a superior alternative to paper filters. Metal strainers are inherently cleanable and reusable. Properly designed, they can withstand temperatures in excess of 500 ° F, extremely high pressure differentials and caustic/corrosive environments.

There are three primary materials with which you can design metal strainers. These are: wire cloth, expanded metal and perforated metal. Each material has its own flow rates and individual characteristics making it a “best fit” for particular engineering requirements. For example, perforated metals can be selected with round holes perforated metal, square holes perforated metal, or any other shape required based on size and or shape of the particulate that needs to be strained.
