Structural Features
● 90 degree bending angle: the elbow is 90 degrees, which can be used for fluid steering in piping systems.
● Male outer thread: one end of the elbow is fitted with a male outer thread, which may be attached to a tube or fitting with an inner thread. The connection of this kind of connection is strong and the sealing is good.
● Material variety: 90 degree male thread elbow can be made from stainless steel, carbon steel, alloy steel and so on, so as to satisfy the requirements of different media and working environment.

Application Scenario
● Oil and gas industry: Used in piping systems for transporting oil, natural gas and other media, connecting pipes of different diameters and realizing fluid steering.
● Chemical industry: Used in chemical production process to connect various equipments and pipelines and fulfill specific fluid control requirements.
● Power industry: In the cooling water system of power stations, it is used to connect cooling water pipes and change the flow direction of cooling water.
● Other industries: such as shipbuilding, papermaking, food processing and other industries in the piping system, but also widely used 90-degree external wire elbow.
