The classification of elbow: according to the Angle, the most commonly used are 45°, 90° and 180° three kinds, in addition, according to the engineering needs also include 60° and other abnormal Angle elbow.
The connection modes with the pipe are: direct welding (the most common way), flange connection, threaded connection with socket type connection, etc.
Production methods can be divided into: pushing, pressing, forging, casting and so on. (Now it is generally pure forged)
304 stainless steel elbow can also be divided into equal diameter elbow, and non equal diameter elbow, equal diameter elbow used to connect the same size of the pipe, non equal diameter elbow used to connect the pipe with different outside diameter.
Manufacturing standards are: national standard, electric standard, water standard, American standard, German standard, Japanese standard, etc.
