Stainless steel round pipe 88.9x2 mm AISI 304 (600 GRIT) — is a premium high-alloyed rolled metal of a large caliber, providing exceptional corrosion resistance, absolute environmental safety, and an unlimited service life in adverse weather conditions. The product has an exact outer diameter of 88.9 mm and a wall thickness of 2 mm, providing an inner through diameter of 84.9 mm. The combination of a solid diameter and a two-millimeter wall guarantees high mechanical strength, excellent resistance to significant wind, vibrational, anti-vandal, and impact loads. The profile is manufactured using advanced automatic TIG (Tungsten Inert Gas) welding technology in an inert gas environment, which guarantees 100% monolithicity of the seam, full tightness, and visual invisibility of the welded joint. The seam is located strictly inside the product, and the entire outer surface of the bar undergoes premium multi-stage processing with ultra-fine abrasives to achieve the highest roughness class of 600 GRIT. It acquires a flawless, ultra-smooth mirror shine (chrome effect) that perfectly reflects light, does not tarnish over the years, maximally simplifies sanitary maintenance, and prevents the retention of any dirt. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This round profile is manufactured from high-quality austenitic stainless steel grade AISI 304, known as the classic "food-grade" stainless steel (known domestic analogue is 08Х18Н10, European standard is EN 1.4301). Due to its high content of chromium and nickel, this alloy forms a stable self-healing oxide layer on the metal surface, providing absolute protection against rust even during prolonged contact with water, atmospheric precipitation, food products, and many chemically active substances. AISI 304 steel is completely non-magnetic, possesses high ductility, and is perfectly suited for mechanical processing (bending, forming) and welding. The products strictly comply with the rigorous requirements of international engineering standards ASTM A-554 (USA) for structural rolled products and EN 10296-2 (Europe), which guarantees flawless calibrated roundness, strict adherence to cross-sectional geometry, and wall thickness stability of 2 mm along the entire length of the product. The country of origin of the products is Vietnam.
Scope of Application and Purpose
Due to its large caliber of 88.9 mm, optimal 2 mm wall, maximum corrosion resistance of AISI 304 steel, and premium mirror polishing of 600 GRIT, this pipe is designed for operation in open outdoor environments and zones with high humidity:
Urban Environment and Road Infrastructure: manufacture of durable sidewalk and anti-parking bollards, parking restrictors, road fences, removable parking barriers, reliable urban traffic management systems, as well as long-lasting bases for road signs, info-board racks, indicator supports, and navigation steles.
Outdoor Structures and Masts: design and assembly of high architectural flagpoles, reliable flag holders, communication masts, and external reinforced brackets designed for constant wind loads.
Zones with Extreme Humidity and Water Transport: construction of fence elements and stairs for swimming pools, structures in coastal and marine zones, as well as the manufacture of parts and auxiliary structures for water transport (yachts, boats, vessels).
Food Industry and Production Workshops: assembly of auxiliary metal structures, frames of technological equipment, protective fences, and transportation lines in food blocks, professional kitchens, restaurants, and processing enterprises where strict sanitary and hygienic standards apply.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural stainless steel rolled products (standard ASTM A-554). Due to the specific nature of the structural TIG weld seam type, this pipe is categorically forbidden to be used as a high-pressure main pipeline in pressure engineering networks. It is designed for non-pressure, gravity, ventilation, or open systems, as well as technical pipelines without pressure.
• Operating Environment: AISI 304 steel grade is designed for long-term outdoor use (in moderate climates) and in aggressive environments. However, the pipe is not recommended to be used without additional approval in highly aggressive chemical environments (for example, in direct contact with concentrated hot acids or under conditions of extreme chloride content).
• Temperature Range: the product demonstrates exceptional structural stability and high resistance to sharp temperature drops. The minimum operating temperature is -196°C (can be used in cryogenic conditions), the maximum continuous operating temperature is +600°C (short-term peak heating without destruction and metal deformation is allowed up to +850°C).
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the flawless chromed shine of the 600 GRIT coating, mild soapy solutions or specialized disinfectants without free chlorine should be used. Cleaning is performed using a soft cloth (microfiber) or a soft foam sponge, which effectively remove dust, light dirt, and fingerprints.
Prohibited Care Products:
It is categorically forbidden to use cleaning agents based on chlorine, active acids, as well as any abrasive powders, stiff metal brushes, or scourers. Abrasives leave micro-scratches on the gloss, which irreversibly destroys the mirror effect and reduces the protective properties of the outer metal layer.
The products are delivered in perfect commercial condition (new). Each bar is supplied in a protective polymer film, which completely guarantees the preservation of the mirror surface against scuffs, scratches, and accidental damage during transportation, loading and unloading operations, and installation.
