Overview of ISO 559 Steel Pipe Standard for Water Supply and Sewage
Standard definition and scope of application
ISO 559:1991 EN is an international standard for steel pipes for water and sewage, which specifies the technical delivery conditions for seamless steel pipes and welded steel pipes used for transporting water and sewage at temperatures between 10 ℃ and 120 ℃, but does not apply to steel pipes and similar flat end pipes that comply with ISO 65.
Development process of standards
ISO 559 has different versions, among which ISO 559:1977 EN is an international standard for welded or seamless steel pipes for water, sewage, and natural gas, but this version has been abolished, discontinued, and no longer updated. ISO 559:1991 EN, as the second edition, cancels and replaces the first edition (ISO 559:1977).
Specific requirements of the standard
Design and Manufacturing Requirements
The manufacturing process requires the use of high-quality materials, precise manufacturing processes, and steel pipes that meet the specified dimensions and shapes.
Material requirements
The chemical composition of steel is specified, including the content of elements such as carbon, silicon, manganese, phosphorus, and sulfur.
Performance Requirement
Mechanical performance: It specifies the mechanical performance indicators of steel such as tension, bending, and impact, so that steel pipes can withstand corresponding pressure and external impact.
Pressure performance: Through the prescribed testing methods, the steel pipe can meet the requirements for use in terms of pressure.
Corrosion resistance: able to resist the corrosion of water and sewage, ensuring the integrity of the pipeline during long-term use.
Sealing performance: The sealing performance of pipeline connection parts to prevent water leakage.
Size, quality, and tolerance requirements
Clarify the size, quality, and allowable tolerance range of steel pipes, as well as the consistency and interchangeability of steel pipes.
Testing requirements
Various methods and standards for testing water pipes have been established, such as testing for pressure, corrosion resistance, sealing, etc., to ensure that the quality of steel pipes meets the requirements.
Marking requirements
Marking is an important means of identifying information such as pipeline type, manufacturer, manufacturing date, and material, facilitating traceability and management of steel pipes.
