High Strength Wedge Wire Screen Tube

Product Introduction

Our high strength wedge wire screen tube, also called Johnson screen tube, is fabricated by welding profiled wedge wire onto longitudinal support rods. The V-shaped opening expands inwards. This all-welded construction delivers much higher load capacity than common woven mesh and perforated plate filters. It works steadily for solid-liquid, solid-gas separation and medium interception under demanding pressure and flow conditions.

Product & Company Advantages (Anping Haopeng Metal Wire Mesh Co., Ltd.)

We are a professional manufacturer based in Anping, China’s wire mesh hometown. We handle the whole production process in-house, from wedge wire forming, automatic welding, finishing to quality inspection and packing.

We tailor slot precision, dimensions and material plans according to your actual working conditions. Both small trial orders and bulk production are acceptable.

Every batch of screen tubes goes through strict inspection before shipment. We check slot uniformity, welding quality and roundness one by one.

Our team provides practical selection and installation suggestions. We maintain stable lead times and can arrange priority production for urgent orders.

Our high strength wedge wire screen tubes are exported worldwide, and we accept third-party inspection as requested.


Customer Feedback

Most buyers comment that our screen tubes hold shape well under high pressure, with no slot shifting after long running hours.

Clients using backwash systems say the tubes clean thoroughly, and flow rate bounces back quickly after each backwash cycle.

Engineering customers mention we revise drawings fast, and custom flanges or threaded ends fit their equipment perfectly.

Users working in corrosive seawater and chemical environments are satisfied with the stable performance of our 316L and duplex steel screen tubes.


FAQ

Q1: Can you produce non-standard sizes and special slot gaps?

A1: Yes. We make custom products based on your drawings or technical specifications.

Q2: Which material suits 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 screen tube can take?

A3: Pressure rating depends on outer diameter, length, material and support rod layout. We will offer a reference value after confirming your working parameters.

Q4: Can I get samples for testing?

A4: Samples are available. Sample cost and freight will be discussed separately.

Q5: What cleaning methods work for wedge wire screen tubes?

A5: Backwashing is the preferred method. Offline high-pressure water washing and ultrasonic cleaning also work. Do not scrape the slot surface with hard tools.

RELATED FAQ
What is Wedge Wire Screen Tube?

The wedge wire filter element is a filter element composed of a "V" shaped stainless steel wire and a stainless steel support strip. Its smooth surface is the filter surface, and the gap is a strip, which belongs to the surface filtration form.

What are the primary applications of wedge wire Screen Tube?

Wedge wire filter elements are widely used in many fields, mainly including petrochemical, food and beverage, pharmaceutical, water treatment.

What is the difference between wedge wire filter elements and other wire mesh filter elements?

The wedge-shaped wire filter element has a higher filtration efficiency and can achieve extremely high filtration effects by controlling the particle gaps of the wedge-shaped mesh.


The wedge-shaped wire filter element is suitable for high-flow and high-pressure industrial filtration occasions, especially for industrial water, drinking water purification, sand separation and treatment, sewage treatment and other fields.

What is the material of wedge wire?

The main material of wedge wire is stainless steel. Specifically, wedge wire is usually made of high-quality stainless steel materials, such as 302, 304, 304L, 316L, etc.

Where are wedge wire screen tube used?

Industries include water treatment, oil and gas, pulp and paper, mining, and food and beverage.

What is the expected lifespan of wedge wire screen tube?

With proper maintenance, wedge wire screens can have a long lifespan, often exceeding 10 years.

What is a perforated metal anti-skid plate?

A perforated metal anti-skid plate is a type of metal plate that combines a perforated design with anti-slip or anti-skid features. 

Where are perforated metal anti-skid plates used?

Industrial Flooring:

Used in factories, warehouses, and production lines as flooring or walkways to provide a non-slip surface for workers.

Staircases and Platforms:

Used for stairs, ladders, and elevated platforms to provide safe access and reduce the risk of slips and falls.

Vehicle and Transport Decks:

Commonly used in trucks, trailers, or shipping containers to create a stable, non-slip surface for cargo handling.

Outdoor and Marine Applications:

Used in outdoor environments such as docks, walkways, and industrial outdoor installations where water or mud can create slippery conditions.

What are the common types of perforated metal sheets?

Perforated Sheet with Raised Patterns: Features raised sections in the perforated pattern for enhanced anti-slip properties.

Serrated Metal Plate: Uses serrated edges or a textured surface in combination with perforations to improve skid resistance.

What is the material of perforated metal sheet?

▪Stainless Steel: Resistant to corrosion and durable, ideal for harsh environments like marine, chemical, or food processing industries.

▪Aluminum: Lightweight and corrosion-resistant, commonly used in transportation, aerospace, and exterior architectural applications.

▪Carbon Steel: Strong and cost-effective, often used in industrial and construction settings.
