Threaded olet is a reinforced pipe fitting used for branch pipe connection. It is mainly used to replace the traditional branch pipe connection methods such as reducing tees, reinforcing plates and reinforced pipe sections. The threaded branch pipe table has outstanding advantages such as safety and reliability, reduced cost, simple construction, improved medium flow path, series standardization, and convenient design and selection. It is especially widely used in high-pressure, high-temperature, large-diameter, and thick-walled pipelines. The body of threaded olet is made of high-quality forgings, and the material is the same as the pipe material.
