ISO 9329-2 | Specifies seamless steel tubes with elevated temperature properties. |
ISO 9330-1 | Addresses welded steel tubes for pressure purposes with room temperature properties. |
ISO 9330-2 | Covers welded steel tubes with elevated temperature properties. |
ISO 7/1 | Specifies threaded joints for steel pipes used in water supply systems. |
Manufacturing and Testing Processes
Steel pipes manufactured under ISO standards undergo rigorous processes to ensure compliance:
- Material Selection: High-grade raw materials are chosen based on specific ISO requirements.
- Fabrication Techniques: Pipes are produced using seamless extrusion or welding methods to ensure structural integrity.
- Dimensional Inspection: Ensures compliance with specified tolerances.
- Mechanical Testing: Includes tensile strength, yield strength, and elongation tests.
- Non-Destructive Testing (NDT): Includes ultrasonic or eddy current testing to detect imperfections.
- Hydrostatic Testing: Verifies the pipe’s ability to withstand specified pressures.
Common Applications
Oil & Gas Industry:
- Used in pipelines for transporting crude oil, natural gas, and refined products under high pressure. These systems ensure environmental safety by preventing leaks.
- ISO standards also facilitate the design of pipelines that can handle extreme temperatures and corrosive substances effectively.
Water Treatment & Distribution:
- Ideal for pipelines transporting potable water or sewage due to their corrosion resistance. They ensure long-term durability in harsh environments.
- ISO-compliant pipes are also used in desalination plants to handle high-pressure water flow efficiently.
Construction & Structural Systems:
- Used in structural frameworks such as bridges and buildings due to their high load-bearing capacity. They offer stability in heavy-duty applications.
- Additionally, ISO standards guide the use of hollow sections in earthquake-resistant designs to enhance safety.
Power Generation:
- Essential for steam pipelines and heat exchangers in thermal power plants where high-temperature durability is critical.
- ISO-compliant pipes are also used in nuclear reactors to handle radioactive fluids safely.
Chemical Processing:
- Utilized in chemical plants for handling corrosive substances due to their resistance to chemical reactions.
- ISO standards help in designing piping systems that can withstand aggressive chemical environments, ensuring plant safety and efficiency.
Available Sizes and Dimensions
ISO-compliant steel pipes are available in a wide range of sizes:
Pipe Size (NPS) | Wall Thickness (Sch STD) | Wall Thickness (Sch XS) |
