Tube rond en acier inoxydable

Stainless Steel Round Tube

1. What is a stainless steel round tube?
Stainless steel round tube is a hollow, round tube made of stainless steel, widely used in the interior decoration and metalworking industries. Key specifications include material, diameter, length, and wall thickness. Compared to special-shaped tubes (such as rectangular and diamond-shaped tubes), round tubes are a more basic form.

2. What are the types of stainless steel round tubes?

By application: Decorative stainless steel round tubes, tubes ronds en acier inoxydable industriel, et tubes ronds en acier inoxydable sanitaire.
Par procédé de fabrication:
tubes sans soudure: Inclut laminé à chaud, laminé à froid, étiré à froid, et tubes extrudés.
Tubes soudés: Inclut tubes soudés à joint droit et tubes soudés en spirale.
Par matériau: 201 tubes ronds en acier inoxydable, 304 tubes ronds en acier inoxydable, et tubes ronds en acier inoxydable 316L.

3. Quelles sont les spécifications des tubes ronds en acier inoxydable?

Matériel: The most common are 201 et 304. D'autres aciers inoxydables austénitiques incluent 201, 202, 301, 304, 316, et 316L.
Diamètres: 9.5, 12.7, 16, 19, 22, 25, 32, 38, 51, 63, 76, 89, 102, 114, 133, 159, et 219 MM.
Épaisseurs: 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.5, 2.0, 2.5, 3.0, et 3.5 MM.
Longueur: Typiquement 6 meters per piece.
Couleur: Typiquement argenté avec une finition miroir. Le placage sous vide au titane peut produire une variété de couleurs, y compris or titane, or rose, Or champagne, Titane noir, coffee gold, bronze, et or zirconium.

4. Comment les tubes ronds en acier inoxydable sont-ils produits?

Processus de production des tuyaux soudés en acier inoxydable: Matières premières → Découpe de bandes → Soudage → Traitement thermique → Redressage → Redressage → Coupe des extrémités → Décapage → Essai hydrostatique → Contrôle (impression) → Emballage → Expédition

Tiré à froid (laminé) tube en acier sans soudure: Billet de tube rond → Chauffage → Perçage → Ébauchage → Recuit → Décapage → Huilage (placage de cuivre) → Traction à froid multi-passes (laminage à froid) → Tube billet → Traitement thermique → Redressage → Essai hydrostatique (Contrôle non destructif) → Marquage → Stockage

Laminage à chaud (tube en acier sans soudure extrudé): Billet de tube rond → Chauffage → Perçage → Laminage croisé à trois rouleaux, laminage continu, ou extrusion → Détubage → Sizing (ou réduction) → Cooling → Billet tube → Straightening → Hydrostatic testing (or Non-destructive testing) → Marquage → Stockage

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

Characteristics of Stainless Steel Welded Pipe:
Avantages: Continuous production, high precision, épaisseur de paroi uniforme, 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:
Avantages: Thicker wall thicknesses are more economical and practical, demonstrating advantages in high pressure, forte résistance, 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, fenêtres, railings, meubles, etc..
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, etc..
