Marine Engineering Super Duplex 2507 Stainless Steel Screen Mesh

Product features:

This marine engineering screen mesh addresses unique challenges in offshore operations through its advanced material and design. First, the 2507 super duplex stainless steel material combines the advantages of austenitic and ferritic stainless steels, offering high tensile strength (≥800MPa) and excellent pitting corrosion resistance, which can withstand long-term immersion in seawater without rusting or deteriorating. Second, the plain-crimped composite weave structure creates a rigid mesh surface that resists deformation under high-intensity vibration and heavy loads, ensuring efficient screening of drilling mud or marine sediments during offshore operations. Third, it has a wide temperature resistance range, remaining stable in low-temperature deep-sea environments or high-temperature industrial processing on offshore platforms. Additionally, it has passed DNV GL and ABS marine industry certifications, ensuring compliance with global offshore engineering safety standards. Its 500kg per square meter load capacity ensures it can handle heavy marine equipment or materials without damage.

Product specifications:

The standard size of this marine engineering screen mesh is 1.2m×4m, with customizable maximum sizes up to 3m×12m to match large-scale offshore screening equipment. The wire diameter is 1.0mm with a tolerance of ±0.04mm, ensuring consistent mesh rigidity and corrosion resistance. The aperture size is 3mm with a tolerance of ±0.15mm, allowing efficient passage of small marine sediments while blocking oversized debris. Made of 2507 super duplex stainless steel that conforms to ASTM A995 standards, it has a hardness of HV 280-320 and elongation rate of ≥25%, providing excellent impact and fatigue resistance. It has passed seawater corrosion testing, showing no pitting or rust after immersion in 3.5% sodium chloride solution for 1000 hours. The pickling and passivation treatment removes surface oxides, further enhancing its corrosion resistance and ensuring compliance with marine environmental protection requirements. It can be customized with reinforced edges using heavy-duty steel bars for easy installation on offshore platforms or screening equipment.

Product application:

This super duplex 2507 stainless steel screen mesh is a critical component in various marine engineering projects. In offshore oil and gas platforms, it is installed on vibrating screens to filter drilling mud, separating solid sediments from drilling fluids and ensuring smooth drilling operations. In seawater desalination plants, it is used for pre-treatment filtration of seawater, removing large debris and marine organisms to protect downstream reverse osmosis membranes. In marine aquaculture, it serves as a barrier for fish farms, preventing predatory fish from entering while allowing water circulation and nutrient exchange. In port infrastructure projects, it is used for corrosion-resistant fencing, protecting port facilities from seawater corrosion and vandalism. It is also suitable for screening marine construction materials, such as sand and gravel used in offshore reclamation projects. Its exceptional corrosion resistance and marine industry certifications make it an essential choice for offshore engineering companies and marine equipment manufacturers.
