Round/Rectangular/Diamond Hole Perforated Filter Tube/Pipe for Oil & Water Treatment
Stainless steel perforated metal tube - round/rectangular/diamond holes
Perforated metal tube is made of perforated metal mesh with a wide range of perforated patterns and open area percent. It can be made from a variety of materials including stainless steel plate, hastelloy plate and mild steel plate through punching and welding. The perforated metal tube can be punched in round hole, square hole, rectangular hole, hexagonal hole and special openings. And the welding type can be direct welding or screw welding. Because of its perforated structure, this type of filter can offer superior resistance to bending and crimping. So it is the ideal choice to be used where need rigidity and durability.
Advantages of stainless steel perforated tube
Stainless steel, unlike carbon steel, features rust resistance and corrosion resistant. It contains chromium, when exposed to oxygen, creates an invisible protective film. Stainless steel types are classified into three different groups based on their ability to be hardened. Austenitic stainless steel, which can be hardened by cold working condition, meets a wide range of design criteria.
Commonly Perforated Stainless Steel Types
One of the most widely used general-purpose stainless steels. It possesses an excellent combination of strength, corrosion resistance and fabricates well. To reduce carbide precipitation when welding, use 304L for its lower-carbon content.
Superior corrosion resistance compared to other 300 series alloys when used in used harsh corrosive environments (ex. sea water, chemicals, etc.). To reduce carbide precipitation when welding, use 316L for its lower-carbon content.
Titanium stabilized stainless steel to prevent intergranular formation of chromium carbide. It exhibits strength characteristics superior to those of 304 stainless, thus making it best suited for parts which cannot be subsequently annealed.
The lowest alloy content of the three general-purpose types. It is a heat-treatable chromium type used for highly stressed parts needing the combination of strength and corrosion resistance.
The lowest chromium content of the stainless steels, 409 combines good elevated temperature corrosion resistance with medium strength, good formability, and overall cost.
A general-purpose non-heat-treatable chromium type used for highly polished trim applications in mild atmospheres. Its strengths are in ductility, formability, good corrosion and oxidation resistance, thermal conductivity and finish quality.
