Hello Pipe Enthusiasts!
In this edition of #SEAPIPipeInsights!, we will discuss an international standard that is highly relevant to public utilities: AWWA C200. This standard is issued by the American Water Works Association (AWWA) and serves as a key reference for the use of steel pipes in water transmission and distribution systems.
What is AWWA C200?
- Full name: AWWA C200 Steel Water Pipe, 6 in. (150 mm) and Larger
- Function and Purpose: Establishes requirements for steel pipes used in water transmission and distribution systems, both potable and clean water.
- Material: Steel pipes with or without protective coatings, manufactured using various welding methods (spiral, longitudinal).
- Diameter: Applicable for sizes ≥ 6 inches (150 mm) up to several thousand millimeters depending on project needs.
- Thickness: Determined by operating pressure and hydraulic conditions of the distribution system.
- Grade: Refers to carbon steel with mechanical properties that meet strength and water pressure resistance requirements.
Scope of the Standard
AWWA C200 covers:
- Steel pipe design → dimensions, tolerances, and fabrication methods.
- Material criteria → carbon steel with mechanical properties suitable for water systems.
- Coating & protection → internal linings and external coatings to prevent corrosion.
- Testing & inspection → including hydrostatic testing to ensure pipes withstand operating pressure.
- Main applications → potable water transmission, clean water distribution, and urban utility projects.
Why is it Important for the Steel Pipe Industry?
- Global relevance: Widely applied in clean water projects in major cities and public utility systems.
- Advantages: Emphasizes water supply safety and distribution reliability, making it a primary reference for EPC companies, utility operators, and steel pipe manufacturers.
- Practical value: By following AWWA C200, water distribution projects can ensure steel pipes with accurate dimensions, sufficient mechanical strength, and optimal corrosion protection.
Conclusion
AWWA C200 is a standard that ensures steel pipes for water distribution systems have precise dimensions, adequate mechanical strength, and effective corrosion protection. By applying this standard, utility projects can guarantee safe and sustainable water supply for communities.
SEAPI is capable of producing steel pipes according to AWWA C200 standards, ranging from diameters of 6 inches up to 140 inches. One of our notable projects under AWWA C200 was the Construction of the Raw Water Reservoir with a capacity of 12,400 m³ for the SPAM Regional Umbulan project.
The commitment of Southeast Asia Pipe Industries to international standards is reflected in various clean water transmission projects, reinforcing its role as a trusted partner in supporting vital infrastructure.
