Tubo rotondo in acciaio inossidabile

1. Cos'è un tubo rotondo in acciaio inossidabile?
Il tubo rotondo in acciaio inossidabile è un tubo cavo, rotondo realizzato in acciaio inossidabile, ampiamente utilizzato nell'interior design e nelle industrie della lavorazione dei metalli. Le specifiche principali includono materiale, diametro, lunghezza, e spessore della parete. Rispetto ai tubi di forma speciale (come tubi rettangolari e a forma di diamante), i tubi rotondi sono una forma più basilare.

2. Quali sono i tipi di tubi rotondi in acciaio inossidabile?

Per applicazione: Tubi rotondi in acciaio inossidabile decorativi, Tubi rotondi in acciaio inossidabile industriali, and sanitary stainless steel round tubes.
By manufacturing process:
Seamless tubes: Include hot-rolled, cold-rolled, cold-drawn, and extruded tubes.
Welded tubes: Include straight seam welded and spiral welded tubes.
By material: 201 stainless steel round tubes, 304 stainless steel round tubes, and 316L stainless steel round tubes.

3. What are the specifications of stainless steel round tubes?

Materiale: I più comuni sono 201 E 304. Other austenitic stainless steels include 201, 202, 301, 304, 316, and 316L.
Diameters: 9.5, 12.7, 16, 19, 22, 25, 32, 38, 51, 63, 76, 89, 102, 114, 133, 159, E 219 mm.
Thicknesses: 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.5, 2.0, 2.5, 3.0, E 3.5 mm.
Lunghezza: Typically 6 metri per pezzo.
Colore: Typically silver with a mirror finish. Vacuum titanium plating can produce a variety of colors, including titanium, oro rosa, Champagne Gold, titanio nero, oro caffè, bronzo, and zirconium gold.

4. How are stainless steel round tubes produced?

Stainless steel welded pipe production process: Raw materials → Strip cutting → Welding → Heat treatment → Straightening → Straightening → End trimming → Pickling → Hydrostatic testing → Inspection (printing) → Packaging → Shipping

Cold drawn (rolled) seamless steel pipe: Round tube billet → Heating → Piercing → Heading → Annealing → Pickling → Oiling (placcatura in rame) → Multi-pass cold drawing (cold rolling) → Billet tube → Heat treatment → Straightening → Hydrostatic testing (Non-destructive testing) → Marking → Storage

Hot rolling (extruded seamless steel pipe): Round tube billet → Heating → Piercing → Three-roll cross-rolling, continuous rolling, or extrusion → De-tube → Sizing (or reducing) → Cooling → Billet tube → Straightening → Hydrostatic testing (or Non-destructive testing) → Marking → Storage

5. What are the characteristics of stainless steel round tubes?

Characteristics of Stainless Steel Welded Pipe:
Vantaggi: Continuous production, high precision, uniform wall thickness, high inner surface brightness, and customizable lengths. Economical and aesthetically pleasing for high-precision, low-pressure fluid applications.
Disadvantages: Thicker wall thicknesses require greater equipment investment and lower economic efficiency; thin-walled pipes offer a relatively better cost-effectiveness.
Characteristics of Stainless Steel Seamless Pipe:
Vantaggi: Thicker wall thicknesses are more economical and practical, demonstrating advantages in high pressure, high strength, and mechanical structures.
Disadvantages: Relatively low precision, potential uneven thickness, pitting and black spots on the inner and outer surfaces that are difficult to remove, requiring offline testing, and high cosmetic costs.

6. What are the uses of stainless steel round pipe?
Stainless steel round pipe is an economical steel material widely used in:

Decoration: Stair railings, finestre, railings, mobilia, ecc.
Industrial Applications: Pipes for transporting oil, gas, water, and steam.
Engineering Structures: Manufacturing of mechanical parts and engineering structures (due to their lightweight advantages).
Other Applications: Production of conventional weapons, firearms, artillery shells, ecc.
