Punching filter tube
ubo produce various grades of perforated stainless steel tubes in 304, 316, 321, 310 and nickel alloys with a dimensional tolerance of +/- 0.015” over a 3 metre length. Perforated tube applications include dye spindles and dye beams, cold pad batch beams, filters and exhaust baffles. We offer a range of perforated tubes in bespoke length and diameter dimensions from a variety of proven materials which can be used for dyeing cotton or fabric within the textile industry, as well as other applications.
We can manufacture perforated stainlesss steel tube solutions with high tolerances and straight or flared ends to allow for unrestricted flow and facilitating flow pressure and temperature measurements. We can guarantee distortion-free products and dimple-free perforations.
Perforated stainless steel tubes are mainly used for filtration. We offer a variety of designs and materials to fit your specific requirements. For its practical and aesthetic features, perforated metal has many potential uses in industries as well as in architecture.
Excellent anti-corrosion ability
Perforated tube is made of high quality stainless steel, and has good ability to resist corrosion from acid alkali and salt, and can meet the special requirements of the wells containing H2S CO2, and high cl- . The slot will not get wider after long-term down hole service.
Excellent body strength and anti-deformation ability
The perforated tube has excellent body strength and anti-deformation ability because of its structure. The filtration jacket is supported by the base pipe, and the strength of the perforated pipe is only 2-3% reduced compared with the API casing or tubing. Even if there are partial deformation, the slot width will not get wider, and the sand control will be not lost.
Varying perforation patterns and percent open area also allows engineers to achieve desired flow rates and size sorting.

Metal filters are used primarily in commercial and industrial/OEM applications. In some applications the goal is to protect downstream components from particulate matter. In other cases, a metal filter can be used to separate, or screen one substance from another. Whether your specific application calls for removing unwanted contaminants from fluid or air, protecting expensive process equipment, or simply separating one material from another, Steellong can manufacture a custom metal filter designed for your exact specifications from wire cloth, perforated metal, or expanded metal
Advantages of metal filters
Metal filters are excellent for use in applications that will include continuous exposure to liquid or moisture, or where paper filters do not offer sufficient rigidity or strength. In addition to outstanding durability, there are other inherent design benefits available with metallic filters. Metal filters can be fabricated by welding and crimping, eliminating the need for adhesives or epoxy bonding. Unlike paper filters, metallic filters can withstand temperature range in excess of 500 ° F. and can withstand extremely high differential pressures. Depending upon metals used, your filter can be designed as compatible with most caustic fluids. Stainless steel filters, for example, offer a high degree of resistance to corrosion in caustic environments. Best of all, metal filters are inherently cleanable and reusable. Reusable metal filters offer superior service life when compared to paper and cloth filters, and are commonly used in metal cutting, engine and compressor oil, and waste water applications.
Metal filters are designed from three basic materials: 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, square holes, or any other shape required based on size and or shape of the particulate that needs to be strained or filtered. Expanded metal and perforated metal filters offer superior rigidity and durability to wire cloth filters. For filters that require intricate bends and pleats to achieve proper performance characteristics, and where durability is less of a concern, wire cloth filters in mesh ranges from 2 x 2 to 5 micron mesh are the clear choice.
Metal Filter Materials
Wire cloth filters, expanded metal filters, and perforated metal filters can be designed and manufactured using the a wide range of materials:
Aluminum Filters
Brass Filters
Bronze Filters
Carbon Steel Filters
Copper Filters
Galvanized Steel Filters
Monel Filters
Stainless Steel Filters
Stainless Steel 304 Filters
Stainless Steel 316 Filters
In some applications, filter design requires a mix of materials for support or to develop a protective underlying or outer structure of expanded or perforated metal or a coarser mesh that guards delicate pleated interior components
