Demister pad price manufacturers

The price of a demister pad is primarily driven by material grade (SS304, SS316L, Monel, PP, or PTFE) and mesh density. Higher surface area densities (typically 150-400 kg/m³) provide better separation efficiency but increase material costs. Additionally, the wire diameter and the complexity of the supporting grid design (heavy-duty vs. light-duty) significantly impact the final quotation.

While PP (Polypropylene) pads offer the lowest initial price, they are limited to temperatures below 90°C. For corrosive environments involving sulfuric or nitric acid, investing in SS316L or Titanium is more economically feasible as it prevents frequent replacement shutdowns. PTFE is the premium choice for extreme chemical resistance, though it carries a significantly higher price point.

Buyers should ensure the supplier adheres to HG/T 21618-1998 (the Chinese industrial standard for wire mesh demisters) or international equivalents like ASME standards. Request a Material Test Certificate (MTC) to verify the chemical composition of the alloy, ensuring it matches the grade you paid for, particularly for nickel and molybdenum content in stainless steel.

For standard circular or rectangular pads, suppliers often quote per piece. However, for large-scale industrial towers, pricing is often calculated per cubic meter or by weight. When comparing prices on Made-in-China.com, always clarify if the quote includes the top and bottom support grids, as these can account for 30-40% of the total unit cost.

Material substitution is a common risk. Require the supplier to perform a PMI (Positive Material Identification) test before shipment and provide a video of the testing process. Using Made-in-China.com's Secured Trading Service can also protect your funds until third-party inspection confirms the material specifications.

Demister pads have a high volume-to-weight ratio. To optimize costs, request vacuum packaging for knitted mesh components to reduce volume. For large diameter pads, choose a segmented (split) design that fits into standard 20GP or 40HQ containers, avoiding the extreme costs associated with 'Out of Gauge' (OOG) shipping.

Provide a detailed technical data sheet (including gas velocity, liquid droplet size, and pressure drop requirements) during the inquiry. Suppliers on Made-in-China.com are more likely to offer volume discounts of 10-20% if you provide annual projected quantities rather than a single one-off spot purchase.

Always verify the supplier's ISO 9001 certification and check their export history. Ensure the Proforma Invoice (PI) clearly states the wire diameter tolerance (usually ±0.02mm) and the mesh weight per square meter, as these are the most common areas where low-quality manufacturers cut corners to lower the price.
