Material Requirements
AWWA C200 does not specify a single steel grade but permits various carbon steels meeting ASTM or equivalent standards (НАПРИМЕР., ASTM A36, A139, A283, A53). Common grades provide reliable strength for water applications.
Typical Mechanical Properties (Common Grades)
| Steel Grade/Reference | Предел прочности, Мин КСИ (МПА) | Предел текучести, Мин КСИ (МПА) | Elongation in 2 в. (50 мм), % мин |
|---|---|---|---|
| ASTM A36 | 58-80 (400-550) | 36 (250) | 23 |
| ASTM A139 Grade B | 60 (415) | 35 (240) | 30 |
| ASTM A283 Grade C | 55-75 (380-515) | 30 (205) | 25 |
| ASTM A283 Grade D | 60-80 (415-550) | 33 (230) | 23 |
Примечание: Exact properties depend on the selected grade and manufacturer certification. Chemical composition varies by steel mill but typically follows low-carbon steel requirements (НАПРИМЕР., C ≤ 0.26%, Mn ≤ 1.65%, и т. д., per applicable ASTM specs).
Product Features
- Excellent Corrosion Resistance → Cement-mortar lining (interior) prevents tuberculation; exterior coating protects against soil corrosion.
- Reinforced Mortar → Spiral wire or mesh/fabric reinforcement maintains mortar integrity.
- High Flow Efficiency → Smooth interior reduces friction (high Hazen-Williams C-factor).
- Structural Strength → Steel core handles high pressure and external loads.
- Proven Longevity → Designed for decades of service in demanding environments.
Приложения
- Municipal water transmission and distribution
- Potable water lines
- Fire protection systems
- Industrial and irrigation pipelines
