Stainless Steel Pipe

Description

Stainless steel pipe is a hollow long steel made of stainless steel. It has the characteristics of corrosion resistance, high strength, high temperature resistance, etc. It is widely used in fluid transportation, mechanical structure, decoration and other fields.
Classification
By material:
Austenitic stainless steel pipe: such as 304, 316, excellent corrosion resistance and processing performance, wide range of uses.
Ferritic stainless steel pipe: such as 430, low cost, weak corrosion resistance, mostly used for decoration and household appliances.
Martensitic stainless steel pipe: such as 410, high hardness, good wear resistance, suitable for knives and mechanical parts.
Duplex stainless steel pipe: such as 2205, has both high strength and high corrosion resistance, suitable for chemical and marine engineering.
By production process:
Seamless steel pipe: made by hot rolling or cold drawing process, no weld, suitable for high pressure and high precision occasions.
Welded steel pipe: made by curling and welding steel plate or steel strip, low cost, suitable for low pressure fluid transportation and structural purposes.
By use:
Fluid delivery pipe: used to transport fluids such as water, oil, gas, etc., requiring corrosion resistance and high pressure resistance.
Structural pipes: used for structural support such as buildings and machinery, requiring high strength and wear resistance.
Decorative pipes: used for railings, handrails, furniture, etc., requiring smooth and beautiful surfaces.
According to surface treatment:
Polished pipes: the surface is polished and has high smoothness, suitable for decoration and food industries.
Pickled pipes: the surface is pickled to remove the oxide layer, suitable for general industrial use.
Sandblasted pipes: the surface is sandblasted to form a frosted effect, suitable for special decoration needs.
Process
Hot rolling: rolling at high temperature, high production efficiency, suitable for thick-walled pipes.
Cold rolling/cold drawing: rolling or drawing at room temperature, precise size, smooth surface, suitable for thin-walled pipes.
Welding: curling and welding steel plates or steel strips into pipes through high-frequency welding or argon arc welding.
Annealing: slow cooling after heating to eliminate internal stress and improve material properties.
Pickling: remove the surface oxide layer and improve corrosion resistance.
Polishing: improve surface smoothness, suitable for decoration and high-end equipment.
Features
Corrosion resistance: Chromium forms a dense oxide film to prevent further corrosion.
High strength: Suitable for applications requiring high strength and wear resistance.
High temperature resistance: Some stainless steels can still maintain their performance at high temperatures.
Easy to process: Good plasticity and toughness, suitable for a variety of processing methods.
Beautiful: Various surface treatments, suitable for decoration and construction.
Environmental protection: Recyclable, in line with sustainable development requirements.
Uses
Fluid transportation: Used for liquid and gas transportation in the petroleum, chemical, food, and pharmaceutical industries.
Building structures: Used for bridges, building frames, stair handrails, etc.
Machinery manufacturing: Used for mechanical equipment, auto parts, bearings, etc.
Decoration engineering: Used for decorative purposes such as railings, handrails, furniture, and lamps.
Energy field: Used in nuclear power plants, wind power generation equipment, solar brackets, etc.
Food industry: Used in food processing equipment, pipelines, storage tanks, etc.
Medical equipment: Used for surgical instruments, medical equipment, disinfection cabinets, etc.
Chemical equipment: Used for storage tanks, pipelines, reactors, heat exchangers, etc.
Stainless steel pipes have become an indispensable material in modern industry, construction and daily life due to their excellent performance and wide range of applications. Their corrosion resistance, high strength and easy processing make them an important part of high-end manufacturing and decoration.
