Stainless steel round pipe 70x1.5 mm AISI 201 (600 GRIT) — is a high-strength, lightweight, and aesthetically flawless element of structural metal products with a hollow round cross-section. The product has a precise outer diameter of 70 mm and a reduced wall thickness of 1.5 mm, providing an inner through diameter of 67 mm. This geometric configuration allows for excellent structural bending stiffness with minimal specific weight, significantly reducing the load on supporting nodes and simplifying installation work. The profile is manufactured using automatic TIG (Tungsten Inert Gas) welding technology in an inert gas environment, which guarantees 100% monolithicity and absolute density of the welded joint. The seam is located inside the product, and the 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 mirror shine (chrome effect) that does not fade over time, prevents the retention of dirt and bacteria, and is as simple to maintain as possible. 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 structural stainless steel grade AISI 201 (well-known domestic analogue is 12X15H9ND, European standard is EN 1.4372). This alloy is легований with chromium, manganese, and nickel, is completely non-magnetic, possesses high ductility and strength, and is perfectly weldable by any known methods. Due to its balanced chemical composition, AISI 201 steel is a significantly more profitable and economical option compared to the classic AISI 304 grade, while providing a sufficient level of strength and wear resistance in favorable conditions. Production of the rolled products is strictly regulated by leading international engineering standards ASTM A-554 (USA) for structural pipes and EN 10296-2 (Europe), which guarantees perfect geometric roundness and wall thickness stability along the entire length of the bar. The country of origin of this series is Vietnam.
Scope of Application and Purpose
Due to its premium mirror polishing of 600 GRIT, high strength, and rational cost, this lightweight stainless steel pipe is an optimal choice for architectural, design, and infrastructure tasks in environments with moderate or low humidity.
Interior Decor and Commercial Furniture: the pipe with a diameter of 70 mm is in high demand in furniture production for creating strong frames, manufacturing premium furniture elements for cafes, bar counters, handrails, railings, and enclosure lines inside the premises of shopping and office centers.
Sports and Exhibition Equipment: construction of solid exhibition stands, stands, masts, advertising structures, as well as elements of professional sports equipment and strength training machines.
Mechanical Engineering and Non-Pressure Networks: manufacturing of parts and components in the transport sector and mechanical engineering, installation of auxiliary structures in food blocks, as well as laying technical non-pressure pipelines and drainage systems without internal pressure.
Recommended Environment: dry indoor spaces, office, residential, and shopping complexes, exhibition halls, indoor production workshops, the transport industry, as well as structures in moderate non-aggressive environments without constant exposure to moisture.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural stainless steel products (standard ASTM A-554). Due to the specific nature of the structural TIG weld seam type and the lightweight 1.5 mm wall, this pipe is categorically forbidden to be used as a high-pressure main pipeline in pressure engineering networks.
• Humidity and Chemical Mode: AISI 201 stainless steel has moderate corrosion resistance, so it is not recommended to be used in environments with constant high humidity, outdoors under direct precipitation, or in highly aggressive chemical zones (concentrated acids, alkalis, salts).
• Thermal Loads: the profile demonstrates excellent stability under thermal loads. The maximum continuous operating temperature is +400°C, maximum short-term heating (peak) is allowed up to +550°C, and the minimum operating temperature reaches -40°C. Resistance to sharp temperature drops is moderate.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original chromed shine of the 600 GRIT coating, mild soapy solutions or specialized disinfectants without free chlorine should be used. Cleaning is performed exclusively with 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 mineral 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 metal's outer 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 logistics, loading and unloading operations, and installation.
