Shanxi Xinshunda Flange Manufacturing Co., Ltd. proudly presents our precision-engineered AWWA Class B Flanges, designed specifically for water transmission and distribution systems requiring reliable, cost-effective connections. These waterworks flanges conform to ANSI/AWWA C207 standards and deliver exceptional performance in medium-pressure municipal applications up to 150 PSI.
Product Specifications
Shanxi Xinshunda's AWWA Class B Flanges feature flat face design with oversized bolt holes for easy field alignment. Our standard product range includes ring flanges, hub flanges, and blind flanges in sizes from 4" to 144" diameter. Each AWWA Class B flange is manufactured from high-quality ASTM A283 Grade C carbon steel with options for various protective coatings including Fusion Bonded Epoxy (FBE), liquid epoxy, or hot-dip galvanizing to ensure longevity in buried or submerged installations.
Engineering Excellence of Our AWWA Class B Flanges
The distinct design characteristics of our AWWA Class B Flanges make them ideal for water infrastructure projects worldwide. Unlike ANSI B16.5 flanges used in oil and gas industries, our waterworks flanges feature full flat faces that safely mate with cast iron valves without risk of hub cracking. The enlarged bolt holes (typically 1/8" over bolt diameter) accommodate field misalignment common in large-diameter pipeline installations.
Our manufacturing process begins with premium steel plates that undergo computer-controlled cutting, precision machining, and rigorous quality testing. Each AWWA Class B Flange is dimensional checked against the latest C207 standard specifications to ensure perfect compatibility with your pipeline system. The optimized thickness provides structural integrity while maintaining competitive weight and shipping costs.
Application Environments
These reliable AWWA Class B Flanges perform exceptionally in municipal water supply networks, wastewater treatment facilities, irrigation systems, fire protection mains, pump station connections, and hydroelectric projects. Their robust construction withstands the demands of underground installation, temperature variations, and continuous exposure to water environments.
Global Shipping & Packaging
We implement professional export packaging for our AWWA Class B Flanges, utilizing fumigated wooden crates with internal protection for sealing surfaces. Each shipment is carefully secured to prevent movement during ocean transit. Our strategic location in Shanxi Province provides excellent logistics connections to major Chinese ports, ensuring timely delivery worldwide.
