90 ° stainless steel elbow

90 ° stainless steel elbow is a common in the elbow, because of the need to connect fitting, only mastering 90 - degree bend specification to use. 90 ° elbow bend is kind of a different Angle, other common and 45 ° and 180 °, in addition, according to the requirements of the project also includes 60 °, and other abnormal Angle bend. The bent material has cast iron, stainless steel, alloy steel, calcined cast iron, carbon steel, nonferrous metal and plastic etc.

90 ° stainless steel elbow forming the basic process is: first, welding a cross section of a polygon or both ends closed multi multi ring shell fan shell, internal filled with medium pressure, with inner pressure and internal pressure under the action of cross section of polygonal gradually became round, and eventually become a circular ring shell. According to the requirements, a circular ring shell can be cut into four 90-degree elbows or six 60-degree elbows or other specifications. The process is suitable for the diameter of the bend and the inner diameter of the elbow is greater than 1. 5. Any size of the large elbow is the ideal method for making large pressure bends.

The 90 ° elbow for pipe fittings, stainless steel pipe fittings. It is used in the branch of the main pipeline. Connect two of the nominal sizes of the same or different pipes to make the pipeline change in a 90-degree direction. The way to connect the pipe is: direct welding (commonly used) flange connection, thread connection and socket connection.
