Wedge wire slot tubes have different classification standards, which can be selected according to your needs.

Pipe Surfaces

• normal type. Cross-section of a regular wedge wire screen tube is a square polygon that is almost circular, and the wedge filaments between the adjacent support rods are straight.
• perfect round type. Perfect round wedge wire screen tubes have a perfectly round cross-section, and a wider filtration range, and better filtration accuracy than normal type.

Flow Direction

• FOTI: From outside to inside
• FITO: From inside to outside
• Radial Slots: Slot orient along the screen diameter in a parallel fashion
• Axial Slots: Slot orient along the screen length in a parallel fashion

Advantages and Features

• Perfect smooth surface without edges and corners, reducing friction and increasing effective filtration area. Our wedge wire slot tubes with strong welding smooth surface and resistant to clogging, are advantageous for users that demand bigger filter areas without having to worry about the possibility of clogging of impurities.
• Special structure, with "self-cleaning" function, not only not easy to block, but also can carry out back wash. Easy maintenance can also be achieved with slot tubes through the use of back flushing techniques.
• Accurate filtering performance. The gap is very uniform, with a minimum gap of 0.015 mm and an error of 0.005 mm, which can meet the requirements of high precision.
• The trapezoidal wire is continuously welded to form a high-density uniform gap, which ensures the opening area and non-clogging, and can avoid the high-density accumulation of sediment to the maximum extent, thus improving the filtration efficiency.
• Long service life and durable, our material wire is corrosion resistance and rust resistance.
• Slot tubes are in particular very popular to the petrochemical and food processing industry as they provide efficient filtration systems for liquid and solid separation.
• It can be customized to make different narrow slot openings, size and raw materials according to the actual needs of users. The stainless steel screen can be produced with a diameter of 20–1500 mm and a length of up to 6000 mm. We can supply wedge wire slot tubes to many varied specifications including custom made end fittings to suit your application.
• The filtering direction can be adjusted according to customer requirements, from inside out or in the opposite direction, to meet customer design requirements to the maximum extent.
• In order to adapt to the environment with special requirements such as high pressure and high temperature, we can make enhanced line gap filter elements according to the needs of customers.

Applications of Wedge Wire Slot Tubes

Our products are widely used in various filtration, screening, dehydration, sewage treatment and other equipment, which can produce 20-1500 mm in diameter, within 6000 mm in length and up to 15 μm in filtration accuracy. The stainless steel wire welding screen tube produced by our company is widely used in various filtering, screening and stripping with its reasonable structure, high filtering precision and high working efficiency is considered as one of the best filtering elements.

• Water Treatment
  • It is used as filters and separators to remove suspended solids and particulate matter from water, and is widely used in drinking water treatment, wastewater treatment, and industrial water treatment.
  • It acts as a filtration medium in desalination, descaling, and softening systems to improve treatment efficiency.
• Chemical
  • It can be used as filtration components in equipment such as reactors, distillation towers, and centrifuges to separate liquids and solids.
  • It is used for sterile filtration in fields such as pharmaceuticals and food processing to ensure product purity.
• Mining
  • It is used for solid-liquid separation and filtration to extract concentrates from slurry, and is widely used in mining beneficiation and coal washing.
  • It can be used for extracting and filtering slurry from tailings ponds.
• Oil & Gas
  • It is used as filters in drilling, oil extraction, and pipeline transportation to separate oil, water, and impurities.
  • It acts as precision filtration in oil and gas processing units to ensure product quality.
• Power
  • It functions as filters for equipment such as turbine generators and boilers to remove suspended solids and impurities from water.
  • It is applied in the cooling water systems of nuclear power plants to ensure safe and reliable operation.
