What CE Certification Really Means for 250 Micron Stainless Steel Mesh

When engineers ask me about ce certification 250 micron stainless steel mesh, they’re usually knee-deep in a project: a filter pack for solvent recovery, a pre-screen for a pharmaceutical centrifuge, or a food-grade strainer that must survive cleaning cycles. And yes, CE comes up fast—because in the EU, assemblies with mesh are often placed on the market under directives that require CE marking (think Pressure Equipment, Machinery, or Construction Products). The mesh itself, to be honest, doesn’t “get” CE in isolation; it underpins a CE-marked system with traceability, materials compliance, and reliable test data.

Product at a Glance

Wire Mesh for chemical from East Industry, Anping City, Hebei, China, is built in SUS302/304/316/304L/316L and woven in Plain, Twill, or Dutch patterns. Features? Acid/alkali/heat/corrosion resistance—exactly what chemical processors expect. In practice, many customers say 316L balances corrosion resistance with weldability and low carbon for clean-room duty. For ce certification 250 micron stainless steel mesh, 316L plain weave is the everyday workhorse.

Process Flow, Testing, and Service Life

Materials are drawn wire (ASTM A580) → precision weaving (ISO 9044) → anneal/flatten → ultrasonic degrease → passivation → dimensional and aperture tests (ASTM E2016) → packaging with heat-seal film and traceable labels. For aggressive media, labs often add ISO 9227 salt spray and ferrite checks for 316L purity. Illustrative test data: salt spray >240 h (no red rust), burst strength ≈1.2–1.6 MPa (60 mesh, plain), particle retention D90 ≈250 µm in water at 0.5 bar. In chemical duty, service life ranges 3–8 years, frankly depending on chloride load and cleaning SOPs.

Where it’s Used (and Why)

• Chemical: solvent recovery filter packs, catalyst retention (PED assemblies), corrosion-prone lines.
• Pharma: centrifuge pre-screens, API slurries—documentation really matters here.
• Food & beverage: mash tuns, syrup screening (EU 1935/2004 compliance possible).
• Machine making: suction strainers, hydraulic return-line filters.
• Mine & petroleum: sand control pre-screens, often backed by Dutch weave layers.

Case notes I’ve seen: a brewery moved to ce certification 250 micron stainless steel mesh 316L and shaved 18% CIP downtime; a pharma plant swapped to Dutch-under-plain composite for better retention; a solvent recycler met PED documentation by pairing 3.1 MTC with pressure-vessel CE paperwork.

Customization and CE Context

For ce certification 250 micron stainless steel mesh inside a CE-marked system, spec the documentation pack early: 3.1 MTC, material grade mapping to EN 10088, RoHS/REACH statements, and, when applicable, food-contact declaration. Options include laser-cut discs, multilayer sintered packs, edge welding, and electropolishing. Your integrator then compiles the technical file and Declaration of Conformity for PED/Machinery as relevant.

Customer feedback: “Aperture uniformity was on point; our dP stayed stable over 6 months,” said a downstream operator. Another noted, “Documentation made our CE dossier easier than expected.” That’s not flashy, but it’s what gets audits signed off.
