Our 14-inch stainless steel 321 wedge wire wrapped Johnson screen tube is a precision-engineered filtration component designed specifically for chemical processing and petrochemical applications. Manufactured by Anping County Xinlu Wire Mesh Products Co., Ltd., this continuous-slot screen tube combines a V-shaped profile wire with longitudinal support rods through resistance welding, delivering exceptional filtration accuracy, structural integrity, and resistance to aggressive chemical environments.
Why 321 Stainless Steel for Chemical Filtration?
321 stainless steel (UNS S32100) is a titanium-stabilized austenitic alloy specifically developed to resist intergranular corrosion at elevated temperatures. In chemical processing environments where temperatures frequently exceed 500°C (932°F), 321 stainless steel outperforms standard 304 and 316 grades by:
Resisting intergranular corrosion in the 800°F–1500°F temperature range
Maintaining structural integrity under thermal cycling conditions
Providing superior resistance to organic acids, alkalis, and chloride-containing solutions
Extending service life in catalytic cracking units, heat exchangers, and reactor internals
For chemical engineers specifying filtration components, 321 stainless steel offers the optimal balance of corrosion resistance, high-temperature performance, and cost efficiency compared to higher-nickel alloys.

FAQ
Q: What is the difference between 321 and 304/316 stainless steel screen tubes for chemical applications?
A: 321 stainless steel contains titanium as a stabilizing element, which effectively resists intergranular corrosion at elevated temperatures (800°F–1500°F), while 304 and 316 may experience sensitization in this temperature range. For high-temperature chemical processes such as catalytic cracking and hydrotreating, 321 is the more reliable choice.
Q: What is the minimum slot size available?
A: The standard minimum slot size is 0.05mm and can be customized based on specific filtration accuracy requirements. The wedge wire structure ensures slot tolerance of ±0.005mm.
Q: Can end connections be customized according to drawings?
A: Yes. We support NPT, BSP, NPS threaded connections, flange connections, welded rings, plain ends, and beveled ends, all customizable according to customer drawings.
Q: Which chemicals is this product suitable for?
A: 321 stainless steel screen tubes are suitable for filtration and separation of organic acids, alkalis, alcohols, chloride solutions, and various other chemical media. For highly corrosive media (such as high-concentration hydrochloric acid), higher-grade alloy materials are recommended.
