perforatedtube

Perforated tube, also known as a perforated pipe or sleeve in some contexts, is a cylindrical conduit whose surface is pierced with a regular array of holes. The perforations can be round or slotted and may follow a uniform or staggered pattern. This design enables controlled interaction between the interior bore and the surrounding environment, facilitating fluid distribution, collection, filtration, ventilation, or drainage depending on the application.

Hole geometry and patterns are central to performance. Hole diameter, pitch (spacing), and pattern influence flow rate, pressure drop, and mechanical strength. Tubes may be open- or closed-ended, and some designs incorporate reinforced sections or end fittings to suit mounting or coupling to other components. Materials vary with application and include metals such as stainless steel and carbon steel, alloys, plastics like PVC or polyethylene, and composite materials. Manufacturing methods include punching, laser cutting, water-jet cutting, drilling, and in some cases chemical etching, with finishes and coatings to improve corrosion resistance.

Common applications span several industries. In drainage and civil engineering, perforated tubes collect or convey subsurface water. In filtration and separation, they serve as housings with internal screens or external filtration media. In HVAC and acoustics, perforated tubes and liners help distribute air or dampen sound. In agriculture, they enable uniform irrigation and nutrient delivery. In oil, gas, and chemical processing, perforated tubes can function as distribution or collection elements within process equipment.

Key considerations when selecting a perforated tube include material compatibility, hole size and pattern, operating temperature and pressure, environmental exposure, cleaning and maintenance requirements, and cost. See also perforated metal, drainage pipe, and industrial filtration systems.
