Stainless steel round pipe 108x2.0 mm AISI 201 (600 GRIT) — is a high-strength, thick-walled structural rolled metal of a large diameter, which combines excellent performance characteristics and high cost-efficiency. Having an exact outer diameter of 108 mm and an increased wall thickness of 2.0 mm (the inner through diameter is 104 mm), this round profile features enhanced spatial rigidity, a solid margin of safety, and high resistance to static loads or bending deformations. The profile is manufactured using advanced automatic TIG (Tungsten Inert Gas) welding technology in an inert gas atmosphere, which ensures 100% monolithicity, reliability, and full tightness of the weld seam located strictly inside the product. The outer surface of the bar undergoes premium multi-stage processing with ultra-fine abrasives to achieve the highest roughness class of 600 GRIT. Due to this, the metal acquires a flawless, ultra-smooth mirror shine (chrome effect) that perfectly reflects light, gives structures a modern premium look, and prevents the accumulation of dust and dirt, maximally simplifying sanitary maintenance. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This large-caliber round profile is manufactured from high-quality austenitic stainless steel grade AISI 201 (domestic analogue is 12Х15Г9НД, European standard is EN 1.4372). In this alloy, a portion of the expensive nickel is strictly balanced and replaced with manganese and nitrogen, which provides the steel with higher mechanical hardness, tensile strength, and excellent weldability at a significantly lower and more stable cost compared to the AISI 304 grade. AISI 201 steel demonstrates good corrosion resistance in moderately aggressive environments and indoors. The products strictly comply with the requirements of international engineering specifications: the American standard ASTM A-554 for structural rolled products and the European standard EN 10296-2. This guarantees the buyer a flawless calibrated roundness, exact cross-sectional geometry, and wall thickness stability of 2.0 mm along the entire length of the bar. The country of origin of the products is Vietnam.
Scope of Application and Purpose
The combination of a large diameter of 108 mm, a reinforced wall, the aesthetics of 600 GRIT mirror gloss, and high mechanical reliability at an affordable price makes this round pipe an optimal choice for solving a wide range of tasks in construction, design, and industry:
Architecture, Interior Decor, and Improvement: erection of durable load-bearing metal structures, frame structures, elements of entrance group designs, creation of large exclusive fences, stair complexes, and handrails in office, shopping, entertainment, and business centers with a controlled (low) humidity level.
Commercial and Exhibition Equipment: installation of massive floor-standing advertising media, media steles, complex structures of exhibition pavilions, turnstiles, fencing systems, and visitor flow separation lines in modern public spaces where the premium appearance of monolithic chromed metal is essential.
Technological Equipment and Ventilation Systems: engineering of protective casings, frames, and screens for machine tools and industrial aggregates, assembly of internal dry ventilation systems, smoke removal, air ducts, and auxiliary metal structures within food blocks and clean production facilities (for structures that do not come into direct contact with food products in an aggressive state).
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 108 mm pipe is categorically forbidden to be used as a high-pressure main pipeline in pressure engineering or utility networks. It is designed exclusively for non-pressure, gravity, ventilation, or open systems, as well as technical pipelines without pressure.
• Operating Environment: AISI 201 steel grade is designed for long-term use indoors with low humidity and in moderate (non-aggressive) environments. The pipe is not recommended to be used under conditions of constant high humidity, outdoors without protective coatings, or in highly aggressive chemical environments, as its corrosion resistance is lower than that of AISI 304 steel.
• Temperature Range: the product demonstrates structural stability and moderate resistance to temperature drops. The minimum operating temperature is -40°C, the maximum continuous operating temperature is +400°C (short-term peak heating without destruction and metal deformation is allowed up to +550°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.
