1. First of all, let's talk about the process:
The process of the seamless elbow is hot pushing, cold pressing, and hot pressing, and the process of the elbow is medium frequency bending, hot pressing, and CNC bending. Among them, carbon steel is the most commonly used elbow in pressure pipes, alloy steel is a hot push, stainless steel is a cold push, and the most commonly used process for
steel elbow is intermediate frequency bending.
2. The difference in scouring strength:
The R of the
steel elbow and the
steel elbow itself is different. R is a position to control the length of the
steel elbow and the
steel elbow. The scouring strength of the small R through the medium is much larger than that of the large R, that is to say, 1D The scour strength of the elbow is not as good as that of the 1.5D elbow. The scour strength of 1.5D elbows is lower than that of
steel elbows, and
steel elbows are more resistant to erosion and wear than
steel elbows.
3. There is also a special case, such as the bridge class. It is necessary to use a large-span
steel elbow to cross it. At this time, a
steel elbow cannot be used. The general heat pipe also uses a
steel elbow.
Steel bends have different uses in different industries, they can be freely extended to further distances with the advantage of bending, and the strength of the building will also be reduced.
Steel elbows are widely used in electric power, petroleum, marine, chemical, and other fields, mainly used in oil transportation, natural gas transportation, and infusion, and play an important role in aircraft and their engines.
