Stainless steel round pipes can be classified according to their purpose, process, material, and shape structure. The following is a detailed introduction:
1\u3001 Classified by purpose
Decorative stainless steel round tube
Application scenarios: Mainly used in decoration fields such as stair handrails, railings, doors and windows, furniture, billboards, etc.
Features: Emphasis is placed on appearance, corrosion resistance, and ease of processing. The surface can be polished, brushed, and plated to meet different decorative needs.
Common materials: 201 stainless steel (low cost, suitable for dry environments), 304 stainless steel (excellent corrosion resistance and processability, widely used).
Industrial stainless steel round tube
Application scenarios: Widely used in industrial fields such as petroleum, chemical, natural gas, water treatment, mechanical instruments, etc., for transporting fluids (such as water, oil, gas, etc.) or as structural components.
Characteristics: It needs to withstand high pressure, high temperature or corrosive media, therefore requiring the pipe to have high strength, corrosion resistance and sealing performance.
Common materials: 304 stainless steel (universal material), 316\/316L stainless steel (containing molybdenum, strong resistance to chloride corrosion, suitable for marine environment or chemical industry).
Sanitary grade stainless steel round tube
Application scenarios: Mainly used in industries with high hygiene requirements such as food, beverage, pharmaceutical, medical, etc., such as beer fermentation tank cooling pipes, medical coated stainless steel hollow pipes, etc.
Characteristics: The inner wall of the pipe is required to be smooth, free of dead corners, and easy to clean to prevent bacterial growth and medium contamination.
Common materials: 304 stainless steel (requiring special polishing treatment), 316L stainless steel (with higher hygiene requirements).
2\u3001 Classified by process
Seamless stainless steel round tube
Production process: After piercing through steel ingots or solid billets, they are produced through processes such as hot rolling, cold rolling, or cold drawing.
Features: No welds, strong pressure bearing capacity, suitable for high-pressure environments; But the production cost is high and the processing difficulty is high.
Application scenarios: high-pressure boiler tubes, petroleum cracking tubes, hydraulic support tubes, etc.
Welded stainless steel round tube
Production process: It is made by rolling steel plates or strips and welding them together, and is divided into straight seam welded pipes and spiral welded pipes.
Features: Low production cost and high production efficiency; But there may be defects at the weld seam, and non-destructive testing is required to ensure quality.
Application scenarios: Decorative pipes, low-pressure fluid delivery pipes (such as water pipes, air pipes, etc.).
3\u3001 Classified by Material
Austenitic stainless steel round tube
Representative materials: 304 stainless steel, 316 stainless steel.
Characteristics: It has good corrosion resistance, toughness, and weldability, and is widely used in various decoration and industrial fields.
Martensitic stainless steel round tube
Representative materials: 410 stainless steel, 420 stainless steel.
Characteristics: It has high strength and hardness, but relatively poor corrosion resistance; Mainly used for manufacturing parts that need to withstand impact loads and wear.
Ferritic stainless steel round tube
Representative material: 430 stainless steel.
Characteristics: It has good corrosion resistance and oxidation resistance, but poor toughness and weldability; Mainly used for manufacturing corrosion-resistant structural and decorative components.
Duplex stainless steel round tube
Representative material: 2205 stainless steel.
Features: Combining the advantages of austenitic and ferritic stainless steels, it has good corrosion resistance, strength, and toughness; Suitable for harsh conditions such as marine environment and chemical industry.
4\u3001 Classified by shape and structure
Ordinary stainless steel round tube
Features: Uniform outer diameter and wall thickness, with a standard circular cross-section.
Application scenarios: Widely used in various decoration and industrial fields.
Irregular stainless steel round tube
Characteristics: Uneven outer diameter or wall thickness, and the cross-section may have special shapes such as elliptical or plum blossom.
Application scenarios: Mainly used for special structural or decorative components, such as car exhaust pipes, art sculptures, etc.<\/p>","protected":false},"excerpt":{"rendered":"
