Chemical production processes are complex-strong acids and alkalis, salt spray, high temperature and pressure, and oily or highly viscous particulate fluids all place extremely high demands on filter screens.Jinhai, adhering to the principle of "demand-driven, engineering-customized,"helps customers design and deliver high-strength stainless steel filter screen solutions,ensuring a balance between filtration efficiency, service life, and ease of maintenance.

      Ⅰ. Define operating conditions and performance objectives

        Any customized work begins with a precise understanding of the operating conditions: media composition and pH value, operating temperature and pressure, maximum allowable pressure difference, particle characteristics, presence of oil or organic matter, online cleaning requirements, and maintenance cycles. Based on these parameters, the engineering team provides target indicators.

      Ⅱ. Material and Surface Treatment Preferred

        For applications with strong chemical corrosion, 316/316L or higher corrosion-resistant stainless steel is the preferred choice. For extreme corrosion resistance or marine environments, duplex or nickel-based alloys can be selected. Electropolishing, passivation, or thicker plating may be necessary to enhance corrosion resistance and reduce contamination.

      Ⅲ. Weaving techniques and structural design

        The filtration performance and anti-clogging ability of a filter screen are highly dependent on its weaving method:

        • Dutch weaving is used for high-precision, fine-pore filtration;

        • Twill and three-shuttle structures offer higher abrasion resistance and self-cleaning properties, suitable for fluids containing hard particles;

        For pressure-bearing or large-pore interception scenarios, multi-strand wound cable mesh or welded grid + filter layer composite structures are used to enhance overall rigidity and impact resistance. At the same time, by appropriately selecting wire diameter and mesh count, an aperture ratio and strength are balanced.

      Ⅳ. Rigorous testing and performance verification

        A complete set of tests is conducted before shipment: pore size and mesh count inspection, tensile and breaking strength testing, salt spray corrosion resistance testing, water permeability testing, and online simulated clogging and cleaning tests. For key projects, third-party reports and batch traceability certificates can be provided to ensure worry-free project acceptance.

        Choosing the right stainless steel filter mesh is not a simple matter of comparing a single parameter, but a systematic project involving materials, weave, edge design, and maintenance systems.
