Product Introduction
Our industrial wedge wire filter cylinder, also called Johnson filter tube, is manufactured by welding triangular profile wire onto parallel support rods with fixed spacing. It forms continuous V-shaped openings on the surface. This unique tapered slot design works much better than perforated plate and woven wire mesh for separation tasks. It is a durable filter element for solid-liquid, solid-gas separation and medium interception in different industrial systems.

Properties
High mechanical strength, good pressure resistance, corrosion resistance, stable filtration precision, consistent slot gap, excellent backwash performance, high temperature resistance and long service life.
Features
1. V-shaped tapered slot, opening widens inward, greatly reduces blockage risk
2. Full welded construction, strong load capacity, suitable for high working pressure
3. Smooth screen surface, low fluid resistance and large flow capacity
4. Slot clearance can be finely customized for different interception standards
5. Simple maintenance, compatible with online backwashing and ultrasonic cleaning
6. Resists deformation under continuous medium impact
Application Scenarios
Water treatment: raw water filtration, wastewater treatment, well sand control, circulating water filtration, RO pre-filtration
Oil and chemical industry: oil-water separation, downhole sand control, resin traps, catalyst recovery
Food and beverage: juice filtration, syrup purification, edible oil filtration, beverage impurity removal
Mining and mineral processing: mine water filtration, pulp classification
Pulp & paper: pulp filtration and fiber recovery
Agriculture: irrigation filtration, anti-clog drip irrigation filters
Other sectors: pharmaceutical production, new energy slurry filtration, seawater desalination
Product & Company Advantages (Anping Haopeng Metal Wire Mesh Co., Ltd.)
We are a professional manufacturer based in Anping, China’s well-known wire mesh hometown. We finish the whole production process in-house, from wedge wire forming, automatic welding, surface finishing to final inspection and packing.
We adjust slot precision, dimensions and material plans according to your actual working conditions. Both small trial batches and large volume orders are acceptable.
Every batch of filter cylinders goes through strict pre-shipment checks on slot gap, welding quality and roundness.
Our team provides practical guidance for product selection and installation. We keep steady lead times and can arrange priority production for urgent orders.
Our industrial wedge wire filter cylinders are supplied to customers across many regions, and we accept third-party inspection as requested.
Customer Feedback
Many buyers comment that our filter cylinders have steady slot consistency and run for a long time without frequent clogging. Most users find the service life longer compared with ordinary woven filter mesh.
Clients equipped with backwash systems say these tubes clean easily, and flow rate bounces back well after backwashing.
Engineering customers mention we revise drawings quickly, and custom flanges or threaded ends fit their existing equipment perfectly.
Customers operating in corrosive environments are satisfied with the stable performance of our 316L and duplex steel filter cylinders.
FAQ
Q1: Can you make non-standard sizes and custom slot gaps?
A1: Yes. We produce custom items following your drawings or technical specifications.
Q2: Which material fits seawater service?
A2: 316L works for mild corrosion. 2205 or 2507 duplex stainless steel is recommended for long-term seawater exposure.
Q3: What is the maximum working pressure this filter cylinder can take?
A3: It depends on outer diameter, length, material and support rod layout. We will offer pressure reference after confirming your full parameters.
Q4: Can I get samples first?
A4: Samples are available. Sample cost and freight will be discussed separately.
Q5: What is the proper cleaning method for wedge wire filter cylinder?
A5: Backwashing is the preferred method. Offline high-pressure water washing or ultrasonic cleaning also works. Do not scrape the slot with hard tools to avoid damage.
Q6: How long is your production lead time?
A6: Regular ready items can ship fast. Custom products normally take 15-20 days, based on order quantity and processing difficulty.
