Customization:	Available
Application:	Cast Iron, Chemical Processing, Construction, Oil and Gas, Water Supply
Pipe Diameter:	Sch5s-Sch160, Xs,Xxs/Custom

Specification	Details
Standard	Hypothetical ASTM A466/A466M (Actual standard is for alloy steel fittings, here assumed for carbon steel pipe)
Outer Diameter Range	Likely large - diameter range, perhaps 100 - 1000 mm considering the original standard's focus on large - scale applications
Wall Thickness Range	Varies based on pressure and application requirements, potentially 5 - 50 mm
Pipe Length	Customizable, commonly 6 - 12 m for ease of transportation and installation in industrial settings

Property	Value
Yield Strength	Generally in the range of 200 - 300 MPa depending on carbon content and manufacturing process
Tensile Strength	350 - 500 MPa, providing sufficient strength for many industrial applications
Elongation	≥ 20%, indicating good ductility which is important for bending and forming during installation
Impact Resistance	Moderate impact resistance at normal temperatures, may decrease at lower temperatures

Element	Content (%)
Carbon (C)	0.15 - 0.30 (typical for carbon steel used in industrial pipes), affects strength and hardness
Manganese (Mn)	0.30 - 1.00, helps in strengthening the steel and improving its workability
Phosphorus (P)	≤ 0.04, controlled to avoid brittleness
Sulfur (S)	≤ 0.05, minimized to prevent hot shortness during processing
Silicon (Si)	0.10 - 0.40, aids in deoxidation and can contribute to strength

Process Step	Details
Steel Making	Carbon steel is produced through a combination of iron ore, coke, and limestone in a blast furnace or an electric arc furnace. The molten steel is then refined to achieve the desired chemical composition.
Pipe Forming	For large - diameter pipes, either seamless or welded methods can be used. Seamless pipes are made by piercing a solid billet and then rolling it into a tubular shape. Welded pipes are formed by bending steel plates into a cylindrical shape and welding the longitudinal seam.
Heat Treatment	May undergo processes like annealing to relieve internal stresses, improve ductility, and enhance the overall quality of the pipe. Normalizing can also be carried out to refine the grain structure and improve mechanical properties.

Environment	Performance
General Industrial Atmosphere	Moderate corrosion resistance. Forms a rust layer over time, which can be mitigated with coatings or inhibitors.
Water - containing Environments	Prone to rusting in the presence of water, especially if oxygen is also present. Galvanizing or using corrosion - resistant coatings can significantly improve resistance.
Mildly Acidic or Alkaline Fluids	Can resist mild corrosion from such fluids for a certain period, but in more aggressive environments, additional protection is needed.

Industry	Applications
Construction	- Large - diameter water supply and drainage pipes in infrastructure projects. - Structural support in some industrial buildings where high - strength pipes are required.
Industrial Plants	- Piping systems for transporting non - corrosive or mildly corrosive fluids, such as compressed air, certain chemicals in dilute forms, and cooling water.
Mining	- Transportation of slurry, water, and other fluids in mining operations. The large - diameter pipes can handle high - volume flow requirements.

Control Measure	Description
Raw Material Inspection	Test the chemical composition of incoming steel materials to ensure they meet the required carbon steel specifications. Mechanical property tests, such as tensile and impact tests, are also conducted on sample pieces.
In - process Monitoring	Monitor the pipe - forming process, including the welding process (if applicable) for proper seam quality. Check dimensions at various stages to ensure they are within the specified tolerances.
Final Product Testing	Conduct non - destructive testing, such as ultrasonic testing to detect internal defects, and hydrostatic testing to ensure the pipe can withstand the required pressure. Visual inspection is also carried out to check for surface imperfections.

Advantage	Explanation
Cost - effectiveness	Generally more affordable compared to alloy steel or stainless - steel pipes, making it a cost - efficient choice for applications where high - end corrosion resistance or special properties are not required.
Good Workability	Easy to form, cut, and weld, which simplifies installation and modification in the field.
Sufficient Strength	Can provide adequate strength for a wide range of industrial and construction applications.
