Polished Round Stainless Steel Pipe

I. Excellent Surface Performance: Dual Advantages of Aesthetics and Protection

• Extremely High Surface Finish: Through mirror polishing (e.g., common grades like 8K, 12K) or brushed polishing, the surface roughness (Ra) can be as low as 0.01–0.8 μm (depending on the polishing grade). Mirror-polished pipes exhibit a mirror-like reflective effect, while brushed-polished pipes present a fine, uniform brushed or matte texture. Both have a high-end visual appeal, making them suitable for high-end decorative scenarios such as hotel lobby columns, home metal decorations, and elevator interiors.

• Enhanced Surface Protection: The polishing process removes the oxide layer, minor defects (e.g., scratches, pitting), and residual impurities on the pipe surface, forming a more uniform and dense surface structure. This not only reduces attachment points for contaminants (e.g., dust, oil stains) but also minimizes the penetration of external corrosive media (e.g., moisture, mild acids/bases) into the pipe, indirectly improving surface stain resistance and rust resistance. It is particularly suitable for environments with high hygiene requirements, such as food processing equipment and bathroom pipelines.

II. Inherited Core Properties of Stainless Steel: Durability and Stability

• Superior Corrosion Resistance: This primarily depends on the stainless steel grade (e.g., common 304, 316, 321). For instance:

• 304 polished pipes contain 18% chromium (Cr) and 8% nickel (Ni), forming a stable chromium oxide passive film in atmospheric or weak acid/alkali environments to resist rust.

• 316 polished pipes, with the addition of 2–3% molybdenum (Mo), have stronger resistance to salt spray, seawater, and strong corrosive media (e.g., some organic acids, chemical solutions), making them applicable in marine engineering and chemical piping systems.

• High Strength and Mechanical Stability: It possesses the inherent high strength of stainless steel (tensile strength typically ≥515 MPa, yield strength ≥205 MPa, varying by material and wall thickness) and good toughness. It is not prone to deformation or fracture at room temperature, can withstand a certain degree of pressure and external impact, and is suitable for scenarios such as fluid transportation (e.g., low-pressure fluid conveyance) or structural support.

• High/Low Temperature Resistance: Depending on the material, it can adapt to a wide temperature range. For example:

• 304 polished pipes maintain stable performance in environments ranging from -196°C (low temperature) to 800°C (high temperature).

• 316 polished pipes have a high-temperature resistance limit of up to 870°C, making them suitable for auxiliary boiler pipes and high-temperature fluid transportation (design must consider wall thickness and pressure).

III. Hygienic and Environmental Traits: Suitable for High-Cleanliness Scenarios

• Easy to Clean, No Hygienic Dead Zones: The smooth polished surface reduces the breeding space for bacteria and microorganisms. Cleaning requires no special tools (e.g., a regular cloth is sufficient for wiping), meeting food-grade (e.g., GB 4806.9) and medical-grade (e.g., GMP) hygiene standards. It is commonly used in food and beverage conveyance pipes (e.g., milk, beer pipes), medical device casings, and internal pipelines (e.g., surgical instrument flushing pipes).

• Eco-Friendly with No Harmful Substance Release: High-quality polished round stainless steel pipes are made of food-grade or medical-grade stainless steel raw materials, containing no heavy metals (e.g., lead, mercury, cadmium) or toxic additives. No harmful substances are released during long-term use, high-temperature sterilization (e.g., autoclaving), or contact with food/medicines, ensuring safety for humans and the environment.
