The stainless steel screen tube features a fully spiral-welded wedge-wire structure, creating inverted trapezoidal filtration slots that are narrower on the outside and wider on the inside. It is characterized by high precision, high flow capacity, excellent structural strength, and ease of backwashing, making it suitable for various solid-liquid and gas-solid separation applications.
Core Product Advantages
Self-Cleaning Filter Slots
The inverted trapezoidal gaps formed by the wedge-wire structure allow particles to "enter and exit freely," ensuring a more thorough backwashing process.
High Flow, Low Energy Consumption
An open area ratio of up to 60% reduces system backpressure, enabling higher processing throughput for the same level of energy consumption.
Robust Corrosion Resistance
Features a fully welded structure with absolutely no adhesive components. Supports a wide range of material options-from 304 stainless steel to duplex steel-to effortlessly withstand various highly corrosive operating environments.
Comprehensive Customization
Whether for miniature tubes or large-diameter filter pipes (10–1000 mm), we offer fully customized, non-standard solutions with slot precision starting from 20μm.
Applications
Petrochemicals
Amine desulfurization, catalyst recovery, crude oil impurity removal, and tower internals.
Water Treatment
Deep-well sand removal, pre-filtration for membrane systems, rotary drum wastewater treatment, and activated carbon recovery.
Mining & Metallurgy
Concentrate/tailings dewatering and dry stacking, solid-liquid separation of mineral slurries, and coal washing media recovery.

FAQ
Q: Can stainless steel screen tubes be used in seawater or acidic media?
A: Yes they can. We think Grade 316L is a choice for seawater or mildly acidic environments.. If the water has a lot of chloride or is very acidic we think Grade 904L or Duplex Stainless Steel 2205 is a better option.
Q: What makes our stainless steel filter tubes different from the ones you can buy anywhere?
A: Our company makes them with a spiral-welded wedge-wire structure. The holes in our filter tubes are shaped like an upside-down trapezoid, which helps prevent them from getting clogged and makes them easy to clean. Our tubes also let water flow through well and are very strong so they last 2 to 3 times longer than the regular kind.
Q: How do you clean the filter tubes?
A: You can use water to clean them from the back or a mix of water and air or even special sound waves. The special shape of the holes, in our tubes makes cleaning easy so you do not have to take them apart very often.
