Product Introduction
Stainless steel wedge wire screen tube, also known as Johnson screen tube, is a precision welded filter cylinder. It is constructed by continuous V-shaped profile wedge wires welded perpendicularly onto longitudinal support rods, forming uniform continuous slots. It is widely used for solid-liquid separation, sand control, water intake and medium filtration. The smooth outer filtering surface helps reduce particle trapping and allows easy backwashing, which is a high-efficiency metal filter element for industrial and water well systems.

Customer Feedback
“Slots are very even, welding is solid, backwashing effect is good, much better than woven mesh filter.”
“We used it for water well sand control. No sand entering the pump after one year running.”
“Haopeng provided material selection suggestion for our seawater project, 2205 duplex steel works perfectly.”
“Fast sample delivery, they adjusted the thread size according to our filter housing drawing.”
FAQ
Q1: What information do you need for quotation?
A: Material grade, outer diameter, length, slot opening, end connection, working medium, pressure and quantity. Drawing is highly appreciated.
Q2: What is your minimum slot size?
A: The smallest slot we can make is 0.05 mm. The slot will be suggested according to your particle size.
Q3: Can you make special thread / flange ends?
A: Yes. Plain end, NPT thread, BSP thread, custom flange, coupling and special adapters are all available.
Q4: How to clean wedge wire screen tube?
A: Mainly backwash with water or air reverse flow. Stubborn dirt can use soft brush or compatible chemical cleaning. The V-shaped slot is anti-blocking and easy to clean.
Q5: What is the difference between wedge wire tube and woven mesh filter tube?
A: Wedge wire tube has higher strength, larger open area, anti-clogging continuous slot, better pressure resistance and longer service life. Woven mesh is usually for finer low-pressure filtration.
Q6: What is the lead time? MOQ?
A: Sample: 3–7 days. Mass order: 15–25 days. Low MOQ, we accept small trial orders.
Q7: Which material should I choose?
A: SS304 for normal fresh water; SS316L for general corrosive water, food & pharma; 2205/2507 duplex steel for seawater, high chloride environment; Hastelloy for strong acid medium.
Q8: Can you provide test certificates?
A: Yes, material certificate (3.1), dimension inspection report and packing photos can be supplied.
