Product Introduction
Our wedge wire screen cylinder, also commonly called Johnson screen tube, is manufactured by welding triangular profile wire onto parallel support rods. It forms continuous V-shaped slots across the screen surface. Compared with woven mesh and punched plate filters, this unique opening structure greatly reduces blocking risk. It works well for solid-liquid, solid-gas separation and impurity interception in many industrial filtration systems.


Properties
High structural strength, good pressure bearing capacity, corrosion resistance, stable filtration accuracy, consistent slot spacing, excellent backwash performance, high temperature resistance and long service lifespan.
Features
1. V-shaped wedge slot, inward widening opening design, less prone to clogging
2. Full welded construction, solid structure to withstand high working pressure
3. Smooth screen surface, low fluid resistance and large flow capacity
4. Slot opening can be customised precisely for different particle retention needs
5. Simple maintenance, compatible with online backwashing and ultrasonic cleaning
6. Strong resistance to deformation under continuous medium impact
Application Scenarios
Water treatment: raw water filtration, wastewater treatment, well sand control, circulating water filtration, RO pre-filtration
Petroleum and chemical industry: oil-water separation, downhole sand control, resin traps, catalyst recovery
Food and beverage: juice filtration, syrup purification, edible oil filtering, beverage impurity removal
Mining and mineral processing: mine water filtration, pulp classification
Pulp and paper: pulp filtration and fibre recovery
Agriculture: farm water filtration, anti-block 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 wedge wire screen manufacturer based in Anping, China’s well-known wire mesh hometown. We handle the whole production process in-house, from wire forming, automatic welding, surface finishing to final inspection and packing.
We tailor slot precision, dimensions and material plans according to your actual working conditions. Both small trial orders and large batch orders are accepted.
Every batch of screen cylinders goes through strict checks on slot uniformity, welding quality and roundness before shipment.
Our team provides practical selection and installation suggestions. We maintain steady lead times and can prioritise production for urgent orders.
Our products are shipped to multiple overseas markets, and we support third-party inspection if required by buyers.
Customer Feedback
Many buyers tell us our screen cylinders have steady and even slot gaps, and they face far fewer clogging issues during continuous operation. Most users find the service life much longer than ordinary woven filter mesh.
Clients with backwash systems comment that our screens clean easily, and the flow rate bounces back reliably after backwashing.
Engineering customers mention we revise drawings quickly, and custom flanged 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 screens.
FAQ
Q1: Can you make non-standard sizes and custom slot gaps?
A1: Yes. We produce custom items following your drawings or technical requirements.
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 the cylinder can take?
A3: It depends on outer diameter, length, material and support rod layout. We will provide a pressure reference once we confirm your full parameters.
Q4: Can I get samples?
A4: Samples are available. Sample cost and freight will be discussed separately.
Q5: What is the correct way to clean wedge wire screen cylinders?
A5: Backwashing is the preferred method. Offline cleaning can use ultrasonic cleaning or high-pressure water jet. Avoid hard scraping tools which may damage the slots.
Q6: How long is your production lead time?
A6: Regular specifications can be delivered fast. Custom products normally take 15-20 days, depending on order quantity and processing difficulty.
