Perforated Sheet Application

Perforated Tubes – Purify Liquids and Sieve Materials

Several filter tubes with square holes, round holes and different size stand on the ground.
PT-1: Perforated tube with different hole patterns apply to various materials.

Perforated tubes are made of aluminum, stainless steel, carbon steel and alloy sheet. According to opening diameter, we design the width of plate and punch holes customized by you.Then these plates are rounded in a spiral or straight strip and welded by argon arc welding. The perforated filter tube surface is processed by electrolytic polishing, galvanization, sandblasting, pickling and passivation.

With durable materials and various models, perforated tubes can filter liquids, solids and air or sieve different materials to ensure the purity. Weakening noise and granary ventilation are also their important functions. With good acid and alkali resistance, sieving tube is a very practical product for filtering ceramic powders, glass materials, plastic materials, soils, mineral aggregates, drug particles, metal powders, etc.

Application of perforated tube:

  • Filter liquids and air, such as water, oil, etc.
  • Sieve different materials and remove impurities, such as in food, pharmaceutical, chemical and environmental protection industry.
  • As various frameworks of filter elements.
  • Weaken the noise.
  • Used for granary ventilation.

Perforated tube features:

  • Uniform welds and good pressure resistance.
  • Accurate roundness and straightness.
  • Smooth and flat surface.
  • High filter precision.
  • Also can cut the noise and ventilate.
  • Resist acid, alkali, low and high temperature, so has a long service life.
