Stainless steel round pipe 114.3x2.0 mm AISI 201 (600 GRIT) — is a high-strength, thick-walled structural rolled metal of a large diameter, combining excellent performance characteristics with high economic efficiency. With a precise outer diameter of 114.3 mm and a reinforced wall thickness of 2.0 mm (inner diameter is 110.3 mm), this round profile features enhanced spatial rigidity, a substantial safety margin, and high resistance to static loads and bending deformations. The profile is manufactured using advanced automatic TIG (Tungsten Inert Gas) welding technology in an inert gas atmosphere, ensuring 100% monolithicity, reliability, and complete airtightness of the weld seam, which is 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. As a result, the metal acquires a flawless, ultra-smooth mirror shine (chrome effect) that perfectly reflects light, gives structures a modern premium look, and prevents dust and dirt accumulation, maximally simplifying sanitary maintenance. The pipe is supplied in standard 6 m long bars.
Material of Manufacture and Standards
This large-caliber round profile is manufactured from high-quality austenitic stainless steel grade AISI 201 (domestic analogue — 12Х15Г9НД, European standard — EN 1.4372). In this alloy, a portion of expensive nickel is balanced with manganese and nitrogen, providing the steel with higher mechanical hardness, tensile strength, and excellent weldability at a significantly lower and more stable cost compared to AISI 304 grade. AISI 201 steel demonstrates good corrosion resistance in moderately aggressive environments and indoors. The products strictly comply with international engineering specifications: American standard ASTM A-554 for structural steel and European standard EN 10296-2. This guarantees the buyer flawless calibrated roundness, exact cross-sectional geometry, and stable 2.0 mm wall thickness along the entire length of the bar. The country of origin is Vietnam.
Scope of Application and Purpose
The combination of the large 114.3 mm diameter, reinforced wall, 600 GRIT mirror finish, and high mechanical reliability at an affordable price makes this round pipe an optimal choice for a wide range of tasks in construction, design, and industry:
Architecture, Interior Decor, and Landscaping: erection of durable load-bearing structures, frames, entrance group elements, creation of large exclusive fences, stair complexes, and handrails in office, retail, exhibition, and business centers with controlled (low) humidity.
Commercial and Exhibition Equipment: installation of massive floor-standing advertising media, steles, complex exhibition pavilion structures, turnstiles, fencing systems, and visitor flow management 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 structures in food processing facilities and clean production areas (for structures not in 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 (standard ASTM A-554). Due to the specific nature of the TIG structural weld, this 114.3 mm pipe is categorically forbidden for use as a high-pressure main pipeline in pressurized engineering or utility networks. It is designed exclusively for non-pressure, gravity-flow, ventilation, or open systems, as well as technical pipelines without pressure.
• Operating Environment: AISI 201 grade steel is designed for long-term use indoors with low humidity and in moderate (non-aggressive) environments. It is not recommended for use in 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 grade steel.
• Temperature Range: the product demonstrates structural stability and average resistance to temperature fluctuations. The minimum operating temperature is -40°C, and the maximum constant operating temperature is +400°C (short-term peak heating without destruction or deformation is permissible up to +550°C).
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the flawless chromed shine of the 600 GRIT finish, use mild soapy solutions or specialized chlorine-free disinfectants. Clean with a soft cloth (microfiber) or a soft foam sponge to effectively remove dust, light dirt, and fingerprints.
Prohibited Care Products:
It is categorically forbidden to use chlorine-based cleaning agents, active acids, as well as any abrasive powders, stiff metal brushes, or scourers. Abrasives leave micro-scratches on the gloss, irreversibly destroying the mirror effect and reducing the protective properties of the outer metal layer.
Products are delivered in perfect commercial condition (new). Each bar is supplied in a protective polymer film, which fully guarantees the preservation of the mirror surface against scuffs, scratches, and accidental damage during transportation, loading/unloading, and installation.
