High pressure flange

High pressure elbow plays a very important role in the pressurized pipeline system. It can not only change the direction of pipeline in the pipeline system, but also increase the flexibility of pipeline, reduce the vibration of pipeline, reduce the restraint of pipeline, and play a good compensation role for thermal expansion. So elbow is in the pressurized pipeline. Very important parts. Elbow in the pipeline is more stress, so it is also a more vulnerable part of the pipeline. The elbow plays a role in changing the direction of the pipeline in the pipeline.

According to the angle division, there are 45 degree elbows, 90 degree elbows and other common angle elbows such as 60 degree elbows, due to the different needs of pipelines, elbow angle is also different.

According to the material classification, there are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. According to the way of pipe connection, there are direct welding, flange connection, hot melt connection, electric melt connection, threaded connection and socket connection.

According to the production process, there are welding elbow, stamping elbow, pushing elbow, casting elbow and so on.

According to the radius of curvature, there are long radius elbows and short radius elbows (long radius elbows refer to the outer diameter of the pipe whose radius of curvature equals 1.5 times; short radius elbows refer to the radius of curvature equals the outer diameter of the pipe).

According to different shapes and uses, there are jacket elbow, double-bearing elbow, flange elbow, different-diameter elbow, seat elbow, internal and external tooth elbow, stamping elbow, push elbow, socket elbow, butt welding elbow, internal wire elbow, etc.
