Product Description
ASTM A234 WPB 90° Elbow
High strength carbon steel butt weld 90 degree elbow designed for oil, gas, and water pipeline systems.
Product Overview
ASTM A234 WPB 90° Elbow is a high-quality carbon steel pipe fitting manufactured in accordance with ASTM A234/ASME SA234 and ASME B16.9 standards. This core pipeline component is made from WPB carbon steel (Grade B), featuring excellent toughness, high tensile strength, and superior weldability for medium to high-temperature service applications.
Designed with a 90-degree angle, this butt weld elbow efficiently changes fluid flow direction in pipeline systems. Available in both long radius (R=1.5D) and short radius (R=1.0D) configurations, it offers robust construction, precise dimensional accuracy, and reliable sealing performance for high-pressure, high-temperature industrial applications across oil, gas, petrochemical, and water transmission industries.
