Brand: TOPTITECH
SKU: 286816615

TOPTITECH's 20um Porous SS316L Filter Tube with 1/4" Tube Socket Weld Union is a precision-engineered, depth-type filtration element manufactured through a controlled powder metallurgy sintering process. This filter tube utilizes grade 316L stainless steel powder, selected for its superior molybdenum content, enhancing resistance to pitting and chloride stress corrosion cracking. The construction yields a rigid, monolithic porous structure with a consistent 20-micron absolute filtration rating, high dirt-holding capacity, and inherent mechanical strength capable of withstanding significant differential pressure and thermal cycling. Its integral 1/4" tube socket weld union, designed for compatibility with premium fluid system components like Swagelok fittings, ensures a robust, leak-free, high-purity connection ideal for critical system integration. The tube's geometry and filtration characteristics are fully customizable to meet specific volumetric flow, housing dimension, and process compatibility requirements.

20um Porous SS316L Filter Tube with 1/4" Tube Socket Weld Union delivers reliable performance in demanding applications, including strong polar solvent filtration, catalyst recovery, high-purity gas and steam filtration, and viscous fluid processing within petrochemical and semiconductor industries. Its sintered 316L matrix maintains excellent permeability and thermal stability for continuous operation in elevated temperature environments while allowing thorough regeneration via back-pulsing, ultrasonic, or chemical cleaning protocols. This repeatable cleanability, combined with the corrosion-resistant material and welded union connection, guarantees extended service life, reduced change-out frequency, and lower total cost of ownership compared to disposable filter media, making it an optimal solution for rigorous filtration and separation duties.

Products Features

Enhanced Corrosion Resistance with 316L Material

The sintered 316L stainless steel matrix provides superior resistance to pitting and chloride-induced stress corrosion cracking compared to standard 304L grades. This material integrity ensures long-term stability when filtering aggressive media such as strong polar solvents, acidic catalysts, or high-purity process chemicals, preventing premature filter failure and metallic contamination.

Rigid Monolithic Structure for High-Pressure Service

Unlike layered or wound filters, the powder metallurgy sintering process creates a single-piece, porous metal tube with exceptional mechanical strength. This monolithic construction allows it to withstand high differential pressure, typically up to 1500 psi, and severe pressure cycling without structural collapse or media migration, guaranteeing consistent 20-micron absolute filtration.

High-Purity, Leak-Free Connection System

The integrally welded 1/4" Swagelok-compatible socket weld union enables a orbital-welded or socket-welded connection, eliminating potential leak paths associated with threaded or compression fittings. This design is critical for maintaining system integrity in ultra-high-purity applications, ensuring zero particle generation or entrapment at the fluid connection point.

Thermal Stability and Regenerative Longevity

The sintered 316L structure maintains pore stability and mechanical properties across a wide temperature range, from cryogenic conditions to sustained 400°C operation. This thermal resilience, combined with the depth filtration mechanism, permits effective in-situ regeneration through back-pulsing, ultrasonic, or chemical cleaning, significantly extending service life and reducing total cost of ownership versus disposable filters.ressive chemical environments commonly encountered in water treatment facilitie
