Perforated tube punch tube filter with different shape holes
Perforated tube is made of aluminum, stainless steel, mild steel and alloy sheet.We supply perforated tube for a wide range of industries of filter elements, hydraulics, oil completion systems, etc.Then we design the plate width and punch holes customized.Then the sheets are rounded in a spiral or straight strip and welded by argon arc welding.With durable materials and different specifications,, perforated tubes can filter liquids, solids and air or sieve different materials to ensure the purity.
Margins of perforated tube: Margins are the blank (un-perforated) area along the edges of the sheet. Normally the margin on the length are 20mm minimum, and margin along the width can be 0 minimum, or at clients’ requests.
Application of perforated tube:
Filter liquids and air, such as water, oil, etc.
Filter different materials and remove impurities, such as in food, pharmaceutical, chemical and environmental protection industry.
As various support for filter elements.
Weaken the noise.
Used for granary ventilation.
Perforated tube features:
Uniform welding,acid,alkali and high pressure resistance.
Accurate roundness and straightness.
Smooth and flat surface.
Efficient filtration.
Easy to clean and long service life
