Manufactured from aluminum, stainless steel, carbon steel, and alloy sheets, perforated tubes are designed with customized hole diameters and plate widths. They are then shaped into spirals or straight strips and welded with argon arc welding. The surfaces of these tubes undergo treatments like electrolytic polishing, galvanization, sandblasting, pickling, and passivation.

Due to their robust materials and varied models, perforated tubes can filter liquids, solids, and air, or sieve different materials, thus ensuring purity. They also play a key role in noise reduction and granary ventilation. The sieving tubes are practical for filtering ceramic powders, glass materials, plastic, soils, mineral aggregates, drug particles, and metal powders because of their strong resistance to acids and alkalis.

Applications of Perforated Tubes:

• Filtering liquids and air, such as water and oil.
• Sieving and purifying various materials in the food, pharmaceutical, chemical, and environmental protection industries.
• Serving as frameworks for different filter elements.
• Noise reduction.
• Ventilation in granaries.

Key Features of Perforated Tubes:

• Uniform welding with high pressure resistance.

What Are Perforated Tubes and How to Choose Them?

Perforated tubes are metal cylinders with holes or slits, allowing the entry or exit of liquids or air. Commonly used in filter applications such as oil filtration, they are also found in underground drainage systems. Often employed in vehicle mufflers, these tubes help in reducing engine noise and filtering exhaust gases.

Architectural Uses of Perforated Tubes

Because of their functional and aesthetic qualities, perforated metal tubes are favored by architects and designers. You will see them in lighting fixtures, conduit ducts, safety guards, and other interior design elements, where they facilitate light or air exchange or help dampen sound.

Choosing the Right Perforated Metal Tubes for Your Needs

Perforated tubes come in a range of patterns, styles, and seam options. Metalex provides two main seam designs for perforated spiral tubes: the flush (outside) and inside lock seam, particularly useful in fluid filtration. We also offer a unique spiral louvered design with a flush lock seam that serves as an alternative to straight seam tubes when welding is unnecessary. Other seam designs include various welded and abutted options.

Materials for making perforated tubing vary according to application needs. These include tin-plated, galvanized metal, stainless steel, brass, and aluminum. The choice of material depends on environmental demands or aesthetic requirements.

For instance, perforated tin-plated metal tubes are predominantly used in filtration applications. Conversely, perforated stainless steel, brass, and aluminum tubes are more suitable for architectural purposes.
