Stainless steel round pipe 26.9x3 mm AISI 304 (600 GRIT) — a heavy-duty thick-walled structural metal product of precise gauge, manufactured from high-quality alloyed food-grade stainless steel of the austenitic class. 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 geometric configuration provides the product with colossal stiffness of the spatial structure, reference long-lasting strength, and absolute resistance to bending, flexing, breaking, or twisting deformations under the influence of critical 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 maximum 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 highly reliable food-grade stainless steel grade AISI 304, which is a direct reference analog of the alloy 08X18N10 according to GOST and the European standard EN 1.4301. Due to the balanced content of chromium (around 18%) and nickel (from 8% to 10%), this metal provides the product with absolute resistance to oxidation and reliable long-lasting operation under conditions of prolonged exposure to moisture, atmospheric factors, and aggressive chemical substances. 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 a maximum wall thickness of 3.0 mm, reference mirror gloss (600 GRIT), and high corrosion resistance of AISI 304 steel makes this pipe an indispensable material for premium design, the food industry, medicine, and construction with increased requirements for reliability and hygiene. The model is mass-used for the manufacture of modern medical, laboratory, kitchen, and retail equipment, high-quality heated towel rails, as well as elements of heat exchange systems. Due to increased stiffness and a thick wall, the profile is ideally suited for creating reliable sports equipment — outdoor pull-up bars, horizontal bars, and professional training apparatus. Increased resistance to salt water and chemical reagents makes this pipe a basic choice for structures on boats, yachts, marine equipment, as well as for installation in coastal zones, swimming pools, saunas, and bathrooms. The product is also used for manufacturing pipeline fittings elements — threaded nipples, barrel nipples, and short threads in non-pressure communications.
Recommended Environment: open air (moderate climate), coastal and marine zones, swimming pools, saunas, bathrooms, restrooms, auxiliary structures of food blocks and production halls, medical institutions, machinery, mechanical engineering, and shipbuilding.
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: despite its high resistance to most organic acids and moisture, this steel grade is not recommended for use in highly aggressive chemical environments or in direct continuous contact with concentrated mineral acids and industrial chlorides.
• Temperature Regime: the alloy grade AISI 304 has exceptional resistance to critical temperature drops. The safe operation range extends from ultra-low cryogenic -196°C to a maximum continuous operating temperature of +600°C. Maximum short-term thermal heating without loss of strength is allowed up to +850°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.
