产品描述

AWWA C210 is an important standard for the inner and outer coatings of steel Water pipes formulated by the American Water Works Association (AWWA for short). This standard is mainly applicable to drinking water distribution systems, ensuring that pipelines meet industry requirements in terms of anti-corrosion, durability and water quality safety.
1. Standard Overview
Scope of application:
- The C210 standard stipulates the requirements for the inner and outer coatings of steel water pipes and is suitable for transporting drinking water or other fluids with strict water quality requirements.
- The core objective is to prevent pipeline corrosion, reduce head loss and ensure water quality meets hygiene standards by standardizing coating materials and processes.
Versions and Updates:
- For the latest version, please refer to the AWWA official website. Generally, standards are revised in response to technological advancements and industry demands.
2. Material and coating requirements
Cement-Mortar Lining
- Material: Cement mortar (conforming to ASTM C150 or C595 standards).
- Thickness: Depending on the pipe diameter, the thickness range is usually between 3/16 inches (4.8 mm) and 5/16 inches (7.9 mm).
- Function: Prevent internal corrosion, reduce frictional resistance, and maintain water transmission efficiency.
  Outer coating (Coal-Tar Enamel or alternative materials)
- Traditional materials: coal tar enamel (which must meet environmental protection requirements), but nowadays more environmentally friendly alternative materials such as epoxy resin are often used.
- Thickness: Generally, a minimum thickness of 0.16 inches (4.1 millimeters) is required to ensure mechanical protection and anti-corrosion.
- Adhesion test: The coating needs to pass a peel test to ensure a tight bond with the surface of the steel pipe.
3. Manufacturing and process requirements
Surface treatment:
- Before coating, the steel pipe needs to undergo sandblasting cleaning to achieve the surface cleanliness standard of SSPC-SP 6/NACE No.3.
Coating process:
- Inner coating: Evenly covered by centrifugal method or mechanical spraying.
- Outer coating: The winding or spraying process should be adopted, and it is necessary to ensure that there are no defects such as bubbles and cracks.
- Curing conditions: The coating needs to be cured under specific temperature and humidity to ensure stable performance.
4. Testing and Inspection
- Thickness detection: Use a magnetic thickness gauge or ultrasonic equipment to measure the thickness of the coating.
- Electric spark test: Check the continuity of the outer coating to ensure there are no pinhole defects.
- Water quality safety: The inner coating needs to pass NSF/ANSI 61 certification to ensure that the material meets the drinking water contact standards.
5. Comparison with other AWWA standards
- C200 series: C210 is part of the steel water pipe standard and complements C200 (bare steel pipe), C213 (epoxy coating), etc.
- Differences: C210 emphasizes the comprehensive protection of both inner and outer coatings, while C213 only targets the fusing epoxy coating on the outer wall.
6. Application Scenarios and Advantages
Typical applications:
- Municipal water supply networks, main water transmission pipes, water conservancy projects, etc.
Advantages:
- Anti-corrosion: Extend the service life of pipelines to over 50 years.
- Water quality protection: The inner coating prevents the precipitation of metal ions.
- Economy: Reduce maintenance costs and water transmission energy consumption.
7. Installation and maintenance suggestions
- Installation precautions: Avoid mechanical damage to the coating. Use non-destructive connection methods (such as flanges or mechanical joints).
- Maintenance inspection: Regularly assess the condition of the coating and promptly repair any local damage.
8. Summary
AWWA C210 provides reliable technical support for the drinking water system by strictly regulating the inner and outer coatings of steel water pipes. Adhering to this standard can effectively enhance the safety, economy and sustainability of the pipeline network, and it is an important reference basis for the design and construction of water affairs projects.
