ASTM A234 WPB refers to a standard for wrought carbon steel fittings used in moderate and high-temperature services. Puddle flanges manufactured under this grade act as a watertight barrier when pipes pass through concrete structures.
These flanges are integrated into pipes and cast into concrete walls, foundations, or slabs. As a result, they block water paths at the interface and protect structural integrity.
Mesta Inc. manufactures these flanges in multiple sizes, ensuring compatibility with diverse project requirements.
Additionally, each flange is inspected and pressure-tested before delivery to ensure quality.
ASTM A234 WPB puddle flanges are widely used in:
These flanges are extensively used across Kazakhstan, India, UAE, Saudi Arabia, and Uzbekistan due to their durability.
When installed properly, ASTM A234 WPB puddle flanges can last for decades. They resist water pressure, temperature changes, and mechanical stress.
Their performance in regions with extreme climates proves their durability and reliability.
These flanges can be used for horizontal and vertical pipe installations, metallic and non-metallic pipelines, precast concrete structures, and retrofit projects.
Mesta Inc. ensures continuous innovation and adherence to global standards.
ASTM A234 WPB puddle flanges are essential for ensuring waterproofing and structural integrity in modern infrastructure.
Choosing Mesta Inc. guarantees durability, performance, and long-term reliability across all projects.
