API Stands for American Petroleum Institute. API Socket Weld Flanges are manufactured to provide high strength and robustness. These flanges are made for high heat purposes. These flanges are commonly used for joining two or more pipes, pumps, or valves. Flanges are one of the most critical tools in the plumbing industry.
API Lap Joint Flange are made from high-quality material and enriched with higher strength. These flanges are constructed with high strength and flexibility. These API flanges are manufactured to resist stress cracking, corrosion, and crevice corrosion.
