Product Introduction
The wedge wire filter screen cylinder, also known as Johnson screen cylinder, is welded by profile wire and support rods at fixed intervals. It forms continuous V-shaped opening slots on the surface. This structure avoids clogging easily compared with ordinary perforated mesh and woven mesh. It is a reliable filter element for solid-liquid separation, solid-gas separation and medium interception.

Features
1. V-shaped wedge slot structure, the opening gradually expands inward, not easy to block
2. All welded structure, strong bearing capacity, can bear high working pressure
3. Smooth screen surface, low fluid resistance, large flow rate
4. Slot size can be precisely customized to meet different interception requirements
5. Easy to clean, supports online backwashing and ultrasonic cleaning
6. Not easy to deform under long-term impact of medium
Application Scenarios
Water treatment: raw water filtration, sewage purification, well water sand control, circulating water filtration, RO pre-filtration
Petroleum & chemical industry: oil-water separation, well sand control, resin trap, catalyst recovery
Food & beverage: juice filtration, syrup filtration, edible oil purification, beverage impurity removal
Mining & mineral processing: mine water filtration, mineral pulp classification
Pulp and paper industry: pulp filtration and fiber recovery
Agriculture: farmland water filter, drip irrigation anti-blocking filter
Other industries: pharmaceutical, new energy slurry filtration, seawater desalination
Product & Company Advantages (Anping Haopeng Metal Wire Mesh Co., Ltd.)
We are a professional manufacturer located in Anping, the hometown of wire mesh in China. We independently complete the whole process from wedge wire forming, automatic welding, finishing, inspection to packaging.
We can adjust slot accuracy, size and material scheme according to customers’ working conditions. We support small batch trial order and mass production.
Our factory implements strict inspection before delivery, each batch of screen cylinders will be checked on slot gap, welding quality and roundness.
We provide technical suggestion for selection and installation. The delivery cycle is stable, and we can arrange priority production for urgent orders.
Our products are exported to many regions, and we can support third-party inspection as required by customers.
Customer Feedback
Customers mention that the slot consistency of our wedge wire cylinders is good, and they rarely encounter clogging problems in continuous running. Many users reflect that the service life is obviously longer than ordinary woven filter mesh.
Customers with backwashing system feedback that our screen cylinders are easy to clean and the flow recovery effect after backwashing is stable.
Some engineering buyers say our drawings can be adjusted quickly, and the customized flanges and thread ends match their equipment well.
Customers for corrosive working conditions are satisfied with the stability of 316L and duplex steel versions.
FAQ
Q1: Can you customize special sizes and slot gaps?
A1: Yes. We make non-standard products according to customer drawings or technical requirements.
Q2: What material should I choose for seawater environment?
A2: Normally 316L is for weak corrosion; 2205 or 2507 duplex stainless steel is recommended for long-time seawater working.
Q3: What is the maximum pressure the screen cylinder can withstand?
A3: It depends on diameter, length, material and support rod layout. We will calculate and give pressure reference after confirming your parameters.
Q4: Is sample available?
A4: Samples can be provided, sample cost and freight can be communicated separately.
Q5: How to clean the wedge wire screen cylinder?
A5: Backwashing is preferred. Ultrasonic cleaning or high-pressure water washing is also available for offline cleaning. Do not use hard scraping tools to avoid damaging the slot.
Q6: What is your lead time?
A6: Conventional stock items can be delivered quickly; customized products usually take 7–15 working days, subject to order quantity and processing difficulty.
