Product Description
Material: stainless steel 316L, 304.
Diameter: 32mm,33mm,37.5mm,38mm,40mm 50mm 60mm.
Filtering precision range: 0.01mm-1.0mm.
The slot is absolutely uniform to ensure the roundness quality and the gap error is small.
Wedge wire is the filter media which are made from shaped wire. The profile / surface wires are accurately aligned and then welded to the support rods mostly by automatic resistance welding. Both the profile and the support wires can be with certain wedge shape or other section shape such as water drop , circle, or keystone.
316 (1.4401), 316L (1.4404), 304, 304L stainless steel are the among the standard material for wedge wire filter elements.
Other exotic materials are also available as request, such as Duplex stainles steel 2205, 2507, SS 904L, Hastelloy C276, Hastelloy C22, etc.
Wedge wire mainly shows in two forms: slotted tubes (cylindrical filter element) and flat screen (Johnson screen, sieve). Filter rating ranges from 25 to 3000 microns.
Advantages of wedge wire filter:
- Strong construction, high strength
- Excellent media retention
- Superb backwash ability
- Less possibility of clogging
- Long service life
- Low Maintenance costs
