Two Different Perforated Pipe for Filter

Filtration is the main application of the perforated sheet. Perforated filter pipe is made of mild carbon steel, aluminum steel, high quality stainless steel sheet. 

The process is punching, bending, rolling, welding, cutting and other processes. 

It is featured by direct filtration, simple process, good air permeability, uniform and stable, precision, no leakage, good regenerability, rapid regeneration, convenient installation, high efficiency, long service life, etc.

There are two type of perforated filter pipe.

Bridge slotted screen

Bridge slotted screen pipe has the bridge openings arranged in rows and are staggered to reduce the negative effect on the screen’s strength. Typically the slots are punched in a flat sheet that is subsequently rolled into a tube and welded. Regarded as the best choice of well tube filter, bridge slotted screen is widely used in the drillings, spring water development and other places.

Specifications

  • Material: Mild carbon steel sheet, stainless steel sheet. 
  • Surface: Anti-corrosive coating and anti-rust coating.
  • Wall thickness: 3.5mm to 7mm.
  • Open area: Up to 12%.
  • Slot width: 1mm to 4mm.
  • Outside diameter: 6-5/8”, 7”, 8”, 9-5/8”, 10-3/4”, 12”.
  • Pipe pattern: Straight and spiral.

Advantages

  • High strength, resistance to twisting, compressive and tensile forces.
  • A smooth hole does not impede the passage of probes, tools, etc.
  • The special structure of slot avoids the particles are stuck in the slot.
  • Permeability capability.

Applications
Bridge filter tube has a higher permeability capability. It is used in hydrogeological exploration, drilling, shaft sinking, reservoirs precipitation, foundation digging precipitation, geothermal development and utilization, spring water development and utilization, geothermal air conditioning, bad wells repaired, groundwater sources.

Perforated pipe

Perforated pipe can be made of mild carbon steel sheet, aluminum steel sheet or stainless steel sheet. It is punched into flat sheet and then fabricated into pipe. The fabrication method can be welded and lock seam.

Lock seam perforated pipe is made by folding up the overlapping edges against each other, then folding them over in the same direction a number of times. It has flush surface outside and lock seam inside.

Welded perforated pipe is manufactured by perforated metal sheet which is cut to desired size and then rolled and welded into a tube.

Advantages

  • Economical - Mild carbon steel perforated pipe.
  • Lightweight - aluminum perforated pipe.
  • Durable - stainless steel perforated pipe.
  • High pressure and high strength - spiral perforated pipe.
  • Firm and strong - lock seam perforated pipe.

Applications

  • Perforated pipe is used in exhaust system; filtration systems, aerospace, paper & pulp, petrochemical, oil and gas, and so on.
  • Mild carbon steel perforated pipe is the most economical among the three materials. It can be used in places where the budget is tight and need the good quality products.
  • Aluminum perforated pipe is more lightweight than other materials and it is corrosive resistant. It can be used in some place where weight should be kept in a low level to ensure smooth operation. 
  • Stainless steel perforated pipe is the most durable pipe which can resist to the corrosion, acid. It can be used in the harsh environments.
