Perforated Metal Tubes
Perforated tubes are round,hollow metal objects that have been
punched with holes in a pattern or series. They are used by the
plumbing,construction,automotive and many other industries for
applications like EMI shielding,acoustical dampening,vehicle
exhaust expulsion,filtration and separation,safety guards and
liquid,gas and vapor diffusion.
Perforated tubes’standard perforated patterns are
straight,staggered or oblong staggered,but many manufacturers are
able to produce tubes with custom perforated patterns.
Their open hole area size is determined by the minimum size of the
particulates being trapped within the tube. Though the perforations
are usually round,some tubes are made with square or slot-shaped
Perforated metal tubes,unlike many other perforated metal
varieties,are infrequently used for decorative purposes. They are
sometimes used in pieces of industrial art,but they are generally
restricted to use as industrial utilities.
The most visible applications of perforated metal tubes are exhaust
systems. Wide,corrosion-resistant perforated exhaust pipes are
standard on most large trucks and in some sport cars and
high-performance utility vehicles. Perforated metal tubes are also
used in Bunsen burners and other gas-fired heating apparatus.
Perforated tubes are most often made of stainless steel or carbon
steel,although aluminum is sometimes used. After perforation,the
sheet metal is cut to size and welded or fastened into the tube
Stainless steel,carbon steel,aluminium and other materials. The
mostly used stainless steel perforated tubes include
Stainless Steel 304
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.
Stainless Steel 316
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.
Hole pattern: round,square,hexagonal,oval and special openings.
Open area: it will determine the strength of the support tube and
the filter flow.
The thickness of metal tubes perforated: 0.2mm to 15mm
Opening diameter: 0.2mm to 100mm

Perforated metal tubes are used throughout many industries for a
variety of applications. However,the most common primary
applications are filtration and exhaust systems.
