Chemical Processing Filter Basket Insert
A chemical processing filter basket insert must connect the filtration opening to the real fluid chemistry, equipment interface, flow path, support, pressure or liquid head, removal access and cleaning method. Maidong reviews custom perforated, woven-mesh and composite basket inserts from drawings.
Direct Answer: The Insert Must Fit the Equipment and the Chemical Duty
Fluid compatibility
Identify every process chemical, concentration, temperature and cleaning agent.
Housing interface
Control seating face, flange, bolt pattern, collar, seal and insertion depth.
Filtration structure
Define perforation, woven mesh or composite layers plus support and flow direction.
Maintenance access
Provide handle, clearance, removal direction and cleaning or replacement method.
Chemical Filter Basket Insert Specification Table
Do not quote from basket diameter and a material grade alone. The housing interface, actual chemistry and filtration structure must be defined together.
| RFQ field | What to provide | Risk controlled |
|---|---|---|
| Chemical duty | Chemicals, concentrations, temperature, contaminants and cleaning agents | Unsupported material assumption |
| Equipment interface | Opening, seating face, flange/collar, bolts, seals and datums | Poor fit or bypass |
| Insert envelope | OD/profile, depth, active length, bottom clearance and removal envelope | Interference inside equipment |
| Filtration medium | Hole or mesh geometry, rating basis, layers and support | Wrong retention or unstable media |
| Operating load | Flow direction/rate, pressure or liquid head and reverse conditions | Incorrect support direction |
| Maintenance | Solids loading, handle, removal cycle, cleaning and quantity | Impractical servicing |
Material Selection Starts with the Real Chemical Exposure
Stainless steel grade selection must consider the process chemicals, concentration, temperature, water content, contaminants, cleaning chemistry, exposure duration and fabrication condition. A generic “chemical resistant” claim is not a usable specification.
Use the 304 vs 316 stainless steel mesh guide as a starting comparison, then confirm compatibility for the actual process.
Perforated, Woven Mesh and Composite Inserts
Perforated insert
Rigid coarse screen or support body defined by hole, pitch, pattern and margins.
Woven mesh insert
Defined square opening or construction-specific dense weave for finer retention.
Composite insert
Fine woven layer supported by perforated metal or a heavier wire structure.
For sheet construction, review the perforated filter basket. For filtration media, compare stainless steel mesh for filtration.
Control the Interface to Reduce Bypass Risk
Show where the insert seats, how it is located, the intended sealing boundary, dimensional clearances and whether fluid can pass around the basket. Define bolt holes, collars, grooves or gasket faces when present.
The broader custom stainless steel filter basket page covers general construction. This page focuses on chemical equipment inserts and service inputs.
Flow, Support and Cleaning
Normal flow
Mark upstream/downstream and which side of the media sees higher pressure.
Support position
Place the rigid layer on the loaded side required by the drawing and flow direction.
Reverse cleaning
State reverse pressure or head separately if backwashing or flushing occurs.
Cleaning chemistry
Check media, support, joints and any seals against the approved cleaning method.
Use the flow-direction and support guide and the metal mesh filter cleaning guide for the related technical inputs.

Typical Chemical-Process Installation Points
Vessel opening
Drop-in or bolted insert collecting solids at an access opening.
Tank return or outlet
Screens recirculating liquid or protects downstream equipment.
Strainer housing
Replaceable basket matched to the housing seat and flow path.
Process cleaning loop
Removable insert collecting released debris while allowing defined maintenance access.
Five-Step Chemical Basket Insert RFQ
1. Identify the chemistry
List chemicals, concentrations, temperature and cleaning agents.
2. Send the equipment interface
Add opening, seat, bolts, seals, datums and removal clearance.
3. Define filtration
State solids, opening/rating, media, layers and support.
4. Add operating conditions
Flow, pressure/head, direction, reverse flow and loading.
5. Release the RFQ
Attach drawing revision, quantity and acceptance requirements.
Chemical Processing Filter Basket FAQ
It is a removable or fixed metal basket installed inside a process vessel, tank, strainer housing or equipment opening to retain solids while liquid follows a defined flow path. The insert must match the housing interface and chemical duty.
304, 316 and 316L are common enquiries, but no grade is universally suitable. Provide the exact chemicals, concentrations, temperature, contaminants, cleaning agents and exposure conditions for compatibility review.
Perforated metal can provide coarse screening or structural support. Woven mesh can provide finer defined openings. Composite inserts combine a fine layer with a rigid supporting body when the duty requires both.
The drawing should define the seating face, flange or collar, seal location if used, clearances and the intended flow boundary. A correct basket opening does not prevent bypass if the equipment interface is incomplete.
Send the equipment or housing drawing, installation interface, basket profile and depth, medium chemistry, temperature, solids, required opening or rating, material, support, flow direction, pressure or head, cleaning method and quantity.
A sample can help identify geometry, but a controlled drawing and service data are still needed to define critical dimensions, material, media, support, interfaces and acceptance requirements.
