Stainless steel round pipe 26.9x3 mm AISI 201 (600 GRIT) — a reinforced thick-walled structural metal product of precise gauge, manufactured from high-quality alloyed stainless steel in which deficient nickel is partially replaced by manganese and nitrogen. The product has a fixed outer diameter of 26.9 mm (in the market, buyers also often search for it as a diameter of 26 mm or 27 mm) and a maximum wall thickness for its size of 3.0 mm, thanks to which the inner through diameter is 20.9 mm. This unique geometric configuration provides the product with extraordinary mechanical strength, colossal stiffness of the spatial structure, and flawless resistance to breaking, bending, or twisting deformations under the influence of intense static, dynamic, and impact loads. The profile is manufactured using advanced high-precision TIG welding technology with complete technological cleaning and multi-stage mirror polishing of the outer weld to the highest roughness class of 600 GRIT (chrome, mirror, gloss). The finish processing with ultra-fine abrasives makes the weld visually and tactually absolutely imperceptible from the outside, guaranteeing flawless aesthetics and bright reflective shine for the product. The pipe is supplied in bars with a length of 6 meters.
Material of Manufacture and Standards
This profile is manufactured from cost-effective stainless steel grade AISI 201, which is a direct analog of the alloy 12X15G9ND according to GOST and the European standard EN 1.4372. Due to the balanced alloying with chromium, manganese, and nitrogen, this metal demonstrates excellent surface hardness, wear resistance, and stable operation under conditions of moderate corrosive aggressiveness. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) and EN 10296-2 (Europe), which guarantees perfect roundness of the product, precision of geometric parameters, and maximum strength of the weld joint. The country of origin for this series of metal products is Vietnam, whose plants are known for strict quality control and a high level of factory surface polishing.
Scope of Application and Purpose
The combination of an increased wall thickness of up to 3.0 mm, reference mirror gloss (600 GRIT), and affordable cost of AISI 201 steel makes this pipe the best choice for durable interior, commercial, and sports metal structures. The model is mass-used for the installation of reliable railings, handrails, protective barriers, as well as for the manufacture of durable medical and retail equipment. Due to increased stiffness and a thick wall, the profile is ideally suited for the manufacture of sports equipment — reliable outdoor and home training apparatus, pull-up bars, and horizontal bars that are resistant to high bending loads. In addition, the product is used in elements of heat exchange equipment and for manufacturing pipeline fittings elements — threaded nipples, barrel nipples, and short threads in non-pressure communications.
Recommended Environment: office, residential, and shopping centers, enclosed spaces with low and stable humidity, auxiliary structures of food blocks, production halls, machinery, mechanical engineering, internal transport, as well as any moderate (non-aggressive) environments.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products and is not designed for internal pressure. It is strictly forbidden to use it in hydraulic systems, high-pressure main pipelines, fuel lines, or pressure communications (it is allowed only as a mechanical blank for non-pressure parts).
• Environmental Specification: taking into account the specifics of the chemical composition of grade AISI 201, it is strictly forbidden to use it in environments with constant high humidity, highly aggressive chemical environments, as well as for outdoor street installation or in coastal marine zones (this can lead to the formation of surface corrosion).
• Temperature Regime: this steel grade has average resistance to temperature drops. The safe operation range spans from -40°C to a maximum continuous operating temperature of +400°C. Maximum short-term thermal heating without loss of strength is allowed up to +550°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original reference glossy shine of the 600 GRIT surface, mild soapy solutions or specialized chlorine-free disinfectants should be applied. Cleaning is performed exclusively with a soft cloth (microfiber) or a foam sponge. The mirror surface does not absorb odors and is easily cleaned of dust.
Prohibited Care Products:
It is not allowed to use agents containing chlorine, active acids, as well as abrasive powders and stiff metal brushes. Failure to comply with these rules leads to micro-damage of the passive protective layer of the product, the appearance of scratches, and dulling of the gloss.
The products are delivered in proper commercial condition (new) in a protective polymer film, which completely minimizes the risk of accidental damage, scratches, and scuffs during logistical operations, warehouse storage, and installation.
