Product Description

This seamless 90-degree long radius butt-weld elbow complies with ASME B16.9 standard and is constructed of ASTM A234 WPB carbon steel. The long radius structure features a bending radius of 1.5 times NPS, ensuring smooth fluid passage and effectively reducing flow pressure loss inside the pipeline.

Typical Application

This elbow is extensively adopted in high-temperature and high-pressure piping systems in petrochemical, oil & gas, power generation, and refinery industries. It functions to alter fluid flow direction and creates durable, leak-free welded connections. The SCH 80 heavy wall thickness endows the fitting with superior mechanical strength and anti-corrosion capacity, perfectly fitting harsh working conditions.
