Petrochemical stainless steel dutch mesh

Petrochemical-Grade Stainless Steel Dutch Weave Mesh | Custom Precision Filtration Mesh for Refinery & Chemical Processing

Our custom petrochemical stainless steel dutch weave mesh is tailor-manufactured targeting harsh refining and chemical production working conditions, specially developed to solve high-temperature crude impurity interception, acidic chemical medium filtration and high-pressure fluid separation pain points in petrochemical plants. Different from general-purpose dutch filter mesh on the market, we adjust wire diameter ratio and weaving density based on petrochemical working parameters like sulfur content, operating temperature and differential pressure, to realize stable micron-grade filtration under long-period continuous industrial running.

Key Technical Features

Customized micron filtration accuracy ranging from 3μm~80μm, matching different petrochemical filtering standards from API and GB;

Pre-stress weaving process improves mesh tensile strength by 30%, avoiding mesh distortion under long-time high-pressure petrochemical medium impact;

All raw metal wires pass in-house salt spray test (ASTM B117 ≥500h), effectively withstand H₂S, dilute sulfuric acid and alkaline medium erosion in petrochemical workshops;

Flat rolled mesh surface, easy to be welded into filter tube, filter disc and basket strainer for integrated petrochemical filter assembly.

Focused on downstream petrochemical full-chain usage, we have mature matching solutions for 4 core refining segments:

Crude Oil Refining: Reverse dutch mesh installed on pre-filter of atmospheric & vacuum distillation unit to intercept mechanical impurities and coke particles;

Catalytic Cracking Unit: 310S high temp dutch weave mesh for reactor flue gas dust & catalyst powder recovery;

Fine Chemical Production: 316L ultra-fine twilled dutch mesh for organic solvent, acid & alkali liquid precision separation;

Offshore Petrochemical Platform: 2205 duplex steel dutch mesh for seawater desalination & platform hydraulic oil filtration.

Founded in Anping (China Wire Mesh Capital) since 1988, our factory owns full automatic dutch mesh weaving production lines and independent QC testing workshop complying with ISO9001 certification. All petrochemical-grade mesh completes 3 times dimensional inspection & filtering performance test before delivery. We support OEM/ODM custom size cutting, roll & sheet production per client’s filter drawing; 90% of our petrochemical mesh products export to over 50 countries including Middle East oil-producing nations, Southeast Asia chemical parks.

Q1: Which material is better for sour crude filtration in petrochemical plant?

A: Duplex 2205 stainless steel dutch mesh is preferred for high-sulfur sour crude, outstanding anti-H₂S corrosion compared with regular 316 grade.

Q2: Can petrochemical dutch mesh be processed into filter disc?

A: Yes, our factory supports deep processing including cutting, punching, welding into filter disc, filter cylinder for petrochemical filter assembly.
