I. Common Cast Iron Pipes Lengths
Cast iron pipe standard length: The standard lengths of cast iron pipes typically include 3 meters, 4 meters, 5 meters, and 6 meters (approximately 9.84 feet, 13.12 feet, 16.4 feet, and 19.68 feet, respectively), which are set for convenient transportation, storage, and installation.
Special Lengths: Based on specific customer needs and project requirements, cast iron pipes can also be customized to special lengths, such as 2.5 meters (approximately 8.2 feet) or 7.5 meters (approximately 24.6 feet).Detailed introduction to the length of cast iron pipes, click to view.
II. Diameter Range of Pipe Castings
Small Diameters: The small diameter range of cast iron pipes usually starts from DN15 (half an inch, approximately 12.7 millimeters), suitable for small water supply and drainage systems and some special application scenarios.
Large Diameters: The large diameter of cast iron pipes can reach DN2000 (80 inches, approximately 2032 millimeters) or even larger, mainly used in large water supply and drainage systems, drainage networks, and industrial fluid transmission fields.We have provided a detailed introduction to the diameter and selection techniques of cast iron pipes in another article.

III. Wall Thickness Grades of Cast Iron Pipes
Thin-walled Pipes: Mainly used in scenarios with low pressure requirements, such as small water supply and drainage systems.
Thick-walled Pipes: Suitable for occasions requiring high pressure resistance or heavy loads, such as large water supply and drainage systems and industrial fluid transmission. The specific wall thickness varies according to actual needs and is usually expressed in millimeters.Detailed introduction to the Material of cast iron pipes, click to view.
IV. Cast Iron Pipe Joint Types
Socket Connection: Connecting pipes through socket joints, suitable for small water supply and drainage systems and low-pressure environments.
Flange Connection: Fixing pipes together through flange plates and bolts, suitable for large water supply and drainage systems and industrial fluid transmission in high-pressure environments. Connection dimensions are usually in millimeters or inches, but internationally, millimeters are preferred.
V. Performance Parameters of Cast Iron Pipes
Working Pressure: Depending on the pipe material and wall thickness grade, the working pressure of cast iron pipes can range from 0.1 MPa (approximately 10.2 kgf/cm²) to 1.6 MPa (approximately 163.3 kgf/cm²).
Impermeability: Cast iron pipes have good impermeability and can effectively prevent fluid leakage.
Service Life: Cast iron pipes have a long service life, generally reaching over 50 years, with low maintenance costs during use.
VI. Material and Classification of Cast Iron Pipes
Material: Cast iron pipes are mainly composed of elements such as iron, carbon, and silicon, made through casting processes.
Classification: Based on material and manufacturing processes, cast iron pipes can be classified into gray cast iron pipes and ductile cast iron pipes. Among them, ductile cast iron pipes are widely used in various complex environments due to their high strength and good toughness.
VII. Application Fields of Cast Iron Pipes
Urban Water Supply and Drainage Systems: Cast iron pipes are widely used in urban water supply and drainage systems due to their durability and corrosion resistance.
Drainage Networks: Cast iron pipes can withstand large water flow and pressure fluctuations, so they are often used in drainage networks.
Industrial Fluid Transmission: In some industrial fields, such as chemicals and petroleum, cast iron pipes are used for transmitting various fluids due to their corrosion resistance and high strength.
