Stable, safe, and durable municipal pipeline systems are essential to urban infrastructure. To meet the stringent procurement requirements for large-scale water supply, wastewater treatment, and pipeline renovation projects overseas, we offer a comprehensive line of AWWA fittings that are ready for mass production and delivery. Our products are available in ductile iron, stainless steel, and carbon steel. All items comply with the authoritative North American waterworks standards. We provide compliant fitting solutions that cater to global EPC contractors, water utilities, and pipe distributors.
1. Full Range Production in Full Compliance with AWWA Standards
AWWA (American Water Works Association) sets globally recognized rigorous specifications for waterworks products, covering material composition, dimensional tolerance, pressure resistance, anti-corrosion coating, and drinking water safety.
Our complete AWWA fitting series includes four core categories:
Ductile Iron Fittings (AWWA C110 / C153)
90°/45° elbows, tees, reducers, flanges, caps, and grooved fittings are cast from QT450-12 ductile iron with a minimum tensile strength of 448MPa, offering outstanding impact and water hammer resistance. Lined with NSF61-certified epoxy coating, they are safe for long-term potable water transmission without harmful substance precipitation, ideal for municipal water and sewage pipelines.
Stainless Steel Water Fittings (AWWA C226 / C228)
304 / 316L stainless steel flanges and welded fittings feature excellent acid, alkali and seawater corrosion resistance, widely applied in desalination plants, water treatment facilities and coastal water supply projects, covering sizes from 13mm to 1800mm with fully interchangeable AWWA standard flange drilling patterns.
Fabricated Steel Fittings (AWWA C208 / M11)
Long & short radius elbows, welded tees, and concentric/eccentric reducers can be customized to any bending angle. Smooth inner surfaces reduce flow loss and are designed for large-diameter, long-distance water transmission mains.
2. Core Advantages for Large Overseas Projects
Strict Hydrostatic Pressure Testing for Zero Leakage
Every finished unit undergoes a 5-second burst pressure test and a long-duration steady pressure inspection. Optimized sealing structures for flanged and grooved joints guarantee leak-free performance under working pressure up to 250PSI, minimizing long-term maintenance costs caused by water hammer.
Standardized Dimensions for Global Interchangeability
All center-to-end dimensions, flange bolt circles and wall thickness tolerances fully match AWWA specifications, allowing direct connection with standard AWWA pipes without on-site modification to accelerate construction progress.
Multi-Layer Anti-Corrosion Coatings for Extended Service Life
Options include internal & external epoxy coating, bitumen coating, and polished stainless steel finish, providing reliable protection for buried, exposed, and sewage pipelines against acidic soil and underground water erosion.
Customization & Mass Supply Available
Custom non-standard shaped fittings, engraved brand logos, and special pressure ratings are acceptable. Our large-scale casting & machining workshops ensure stable bulk order delivery for overseas infrastructure projects with controllable lead time.
3. Commitment to Standardized Waterworks Product Supply
We have focused on R&D and manufacturing of water supply pipe fittings for years, continuously upgrading production lines and testing equipment to keep pace with updated AWWA standards. The launch of full-series AWWA Fittings completes our supply system for North American, Southeast Asian, and Middle Eastern water projects, enabling integrated supporting procurement of pipes, valves, and standard fittings for partners.
