Johnson wire well filters

Filter pipe products – Johnson wire filter pipe , also known as wedge wire filter tube .

Other titles: Johnson wire around the filter tube , wedge wire filter tube .

Wedge wire screen pipe

Wedge wire screen tube, also called round slot tube. It is made of stainless steel wire, which is the most popular type because of outstanding chemical stability and corrosion resistance.

The wedge wire screen tube is composed of working profile and support profile. It is produced on an automotive machine. The support profiles is placed on the suit position of the machine, during the surface profiles are spirally wounding, the support profiles are welded onto the surface profiles.

Johnson wire filter pipe technical parameters :

Material: iron, galvanized sheet, stainless steel

Surface treatment: hot dip galvanized, cold galvanized, electrolytic polishing

Features: Johnson wire filter pipe is composed of V-shaped wire and support bar, each cross-point connection by welding, solid structure, good mechanical properties. V-section to avoid blockage, while ensuring smooth flow of water. Continuous gaps have a larger water area, while reducing the infiltration rate of groundwater to prevent the sand under a larger water pressure into the tube, better sand filter. Gaps can also vary depending on the geology.

Uses: Backwash filter on the application, for centrifuges or similar machines. They can be designed to fit filter mats to an existing frame and also be constructed as a unitary support structure. Johnson wire filter can be used for pulp and paper and mineral processing, but must be particularly hard against high centrifugal force and high temperature, also need to have special wear resistance. Long cage filter can also be used for sugar processing, but the design should pay special attention to minimize errors, cracks should be subtle.
