Custom-engineered filtration solutions compatible with acids, solvents, hydrocarbons, fuels, and industrial chemicals. Built for continuous operation under high temperature, high pressure, and chemically aggressive conditions.
Filtration Challenges
Petrochemical and chemical processing environments place the most demanding requirements on filter elements. Streams containing hydrocarbons, solvents, acids, and high-temperature gases cannot tolerate filter media that corrode, deform, or shed particles into the process.
In these environments, filter failure is not just a maintenance issue — it can mean contaminated product batches, equipment damage, or safety incidents. The filter element must perform consistently, not just on day one.
All-stainless steel construction — from the filter media to the end caps and support structure — eliminates the risk of media migration and ensures compatibility across the full range of chemical media encountered in petrochemical processing.
Product Selection
Three product lines that cover the core filtration requirements across petrochemical and chemical processing stages.
Multi-layer diffusion bonding ensures structural integrity under extreme pressure and temperature. Uniform pore distribution maintains consistent filtration accuracy across long service cycles.
All SS316L construction — media, support layers, and end caps. Compatible with acids, solvents, hydrocarbons, fuels, and polymers. Maximum differential pressure 17 bar forward.
Self-cleaning design for automated filtration systems. Contaminants are periodically removed through reverse-flow backwashing — no process shutdown, no manual replacement.
Selection Guide
Matching filter type, material grade, and operating parameters to your specific process stream and conditions.
| Process Stream | Recommended Product | Filtration Rating | Material | Key Requirement |
|---|---|---|---|---|
| Solvent filtration | Pleated Cartridge | 1–200µm | All SS316L | Chemical compatibility, no media shedding |
| High-temp gas filtration | Sintered Mesh Filter | 1–50µm | SS316L / 310S | Up to 600°C, structural stability |
| Hydrocarbon processing | Pleated or Sintered Mesh | 5–100µm | SS316L | Pressure resistance, cleanable |
| Continuous process lines | Backwash Filter Cartridge | 25–3000µm | SS304/316L | Auto self-cleaning, ≤10 MPa |
| Highly corrosive media | Sintered Mesh Filter | 1–200µm | Hastelloy / Inconel / Ti | Maximum corrosion resistance |

Application Cases
Filtration solutions delivered to petrochemical equipment manufacturers and chemical processing companies.
Challenge: A European chemical equipment OEM required SS316L pleated cartridges for solvent filtration housings. Previous mixed-material cartridges (polymer end caps) were failing due to solvent attack on the sealing components.
Solution: Full all-SS316L construction — media, support layers, and end caps. Electrolytic polishing and passivation testing applied to every batch. Custom lengths matched to existing housing.
Result: Zero seal failures across 6 production batches. Adopted as the standard replacement cartridge across the customer's full solvent processing product line.
Challenge: A petrochemical plant needed filter elements for gas streams operating above 400°C. Standard woven mesh filters were deforming and losing dimensional accuracy under sustained thermal cycling.
Solution: Multi-layer SS316L sintered mesh filter elements, 10µm rating, manufactured through high-temperature diffusion bonding. Custom diameter and length matched to the process vessel connection.
Result: Stable filtration accuracy maintained through 12 months of continuous operation including thermal cycling. No deformation or dimensional drift observed at inspection.
Challenge: A North American petrochemical company needed to eliminate production stoppages caused by manual filter element replacement in a high-solid-content process stream. Downtime cost was significant.
Solution: Automatic backwash filter cartridges with Basket Filter structure, 200µm rating, operating pressure ≤6 MPa. Self-cleaning cycle triggered by differential pressure sensor.
Result: Continuous operation achieved with zero planned downtime for filter maintenance. Manual intervention reduced to quarterly inspection only.
FAQ
Common questions about stainless steel filter elements for petrochemical and chemical processing.
SS316L is the standard choice for most chemical processing applications due to its low carbon content and enhanced corrosion resistance against acids and chlorides. For highly aggressive media — strong acids, chloride-rich streams, or extreme temperatures — we offer Hastelloy C276, Inconel 600, Monel 400, and titanium as alternative materials. We specify the appropriate grade after reviewing your media composition and operating conditions.
Our pleated SS316L filter cartridges are rated for –268°C to +371°C. Sintered mesh filter elements handle up to 600°C continuously. For applications above 600°C, we recommend sintered filters in 310S or high-nickel alloy materials. All temperature ratings apply to the full filter assembly including end caps and seals — not just the filter media.
All filter elements undergo electrolytic polishing and passivation treatment to remove free iron residues from the stainless steel surface. We use a passivation test kit (detects free iron on SS and titanium surfaces, up to 200 tests per kit) to verify 100% surface cleanliness before packaging. Material mill test reports confirming chemical composition are included with every shipment.
Yes. Our backwash filter cartridges use a Basket Filter or reinforced mesh structure that provides excellent anti-clogging capability. The self-cleaning cycle is triggered by differential pressure — when the pressure drop across the element reaches a set threshold, reverse-flow backwashing clears the accumulated solids. This design is specifically suited to high-solid-content or variable-load process streams where conventional elements would require frequent manual replacement.
Yes — drawing-based customization is our standard working mode. We support all common connection types (DOE, 222/226, threaded M20–M42) and can manufacture to any OD, ID, and length combination. Send us your existing filter drawing or the dimensions of the element you need to replace, and we will assess feasibility, confirm tolerances, and provide an initial sample within 48–72 hours of drawing confirmation.
We offer the following seal materials: EPDM, NBR, Viton (FKM), Silicone, PTFE, and PFA-coated Viton. For petrochemical and chemical applications, Viton is the most common choice due to its broad chemical resistance across hydrocarbons, fuels, and many acids. PTFE is recommended for highly aggressive acids or where zero contamination risk is required. Please specify your process media when enquiring so we can confirm the right seal material.
